The present invention relates to pesticidal compositions comprising mixtures of O,O-dimethyl S-phthalimidomethyl phosphorodithioate or suitable salt forms thereof, and at least one benzoylurea based chitin inhibiting compound and especially preferably one or more of (RS)-1-[3-chloro-4-(1,1,2-trifluoro-2-trifluoromethoxyethoxy)phenyl]-3-(2,6-difluorobenzoyl)urea (also interchangeably referred to as “novaluron”) or suitable salt forms thereof, and 1-(2-chlorobenzoyl)-3-(4-trifluoromethoxyphenyl)urea (also interchangeably referred to as “triflumuron”) or suitable salt forms thereof, for the control of undesired pests, preferably for the control of Codling moths in fruit. In a further aspect the present invention relates to methods for controlling the presence of undesired pests in fruit, and fruit bearing trees which method comprises the step of applying a pest controlling effective amount of O,O-dimethyl S-phthalimidomethyl phosphorodithioate or suitable salt forms thereof, and/or at least one benzoylurea based chitin inhibiting compound and especially preferably one or more of (RS)-1-[3-chloro-4-(1,1,2-trifluoro-2-trifluoromethoxyethoxy)phenyl]-3-(2,6-difluorobenzoyl)urea or suitable salt forms thereof, and 1-(2-chlorobenzoyl)-3-(4-trifluoromethoxyphenyl)urea or suitable salt forms thereof wherein both said compounds are concurrently present on a treated fruit tree or fruit crop, for the control of undesired pests, in certain preferred embodiments, for the control of Codling moths in fruit crops.
The control of undesired insect pests in orchards of fruit trees is of significant technical and agricultural importance, as the infestation of such pests in fruits reduces the attractiveness of the fruit crop as well as reducing the overall useful fruit crop yield. Such is undesirable not only from a commercial standpoint, but perhaps more importantly from a supply-side standpoint in reducing the useful yields which can then be made available for ultimate human consumption. Thus, minimization of the incidence of such undesired fruit pests in orchards of fruit trees is very desirable. Furthermore, minimization of the quantities of active agents, e.g., pesticides, insecticides, etc. is also very desirable in reducing the amounts of and/or the frequency of application of such active agents onto fruit crops, e.g., fruit trees.
The prior art had suggested various active agents and regimens for their application for the control of certain undesired pests on fruit crops. Such include those published in the following documents: “Use Your New Control Options in Pest Control: Focus on Codling Moth and Leafrollers”, by Jay. F. Brunner, et al. (Washington State University, Tree Fruit Research and Extension Center, Wenatchee, Wash. (2004)); “Codling Moth Control with Rimon (Novaluron) and Other Reduced Risk Insecticides—Research Trial and Demonstration—IPM Apple Orchard, Kaysville, Utah” by Diane Alston, et al., (Utah State University, 2006); Abstract titled “Control of Codling Moth in Large Plot Apple Trials with Diamond 7.5 WG” by Ron Britt et al., an Abstract titled “Control of Codling Moth in Large Plot Apple Trials with Diamond 7.5 WG” by Vernon Fischer et al., and an Abstract titled “Managing Codling Moth in Southern Oregon Pear Orchards: Neonicotenoids, Novaluron, and Granulosis Virus” by Richard J. Hilton, et al., an Abstract titled “Efficacy and Field Longevity of Insecticides Used for Codling Moth” by Chuck A. Ingels, et al., and an Abstract titled “Codling Moth Control Strategies with New Chemistries” by Keith R. Granger, et al., all of the foregoing published as “Abstracts of the 78th Annual Western Orchard Pest & Disease Management Conference”, published by Washington State University, Pullman, Wash. (2004). Further publications include a protocol published by the Ontario—Ministry of Agriculture, Food & Rural Affairs titled “Codling moth programs”, listing Kathryn Carter as the author, and that this internet publication was made available 24. Apr. 2008.
As indicated in the foregoing most of the foregoing regimens require the sequential application of different classes of pesticides, typically at relatively high dosages of active constituents in order to provide satisfactory control of undesired insects pests, particularly of Codling moths. This specific pest is particularly pernicious as it infests the growing fruit and is known to devour part of the interior thereof during its growth cycle. Such results in visually unattractive fruit, when on it is interior is also discolored and/or partially consumed, each of which foregoing factors require the discarding of the otherwise ripened fruit. Thus, there remains a real need in the art for further improved treatment compositions, and treatment regimens for the improved control of undesired pests, particularly Codling moths on fruit crops. It is to these and further needs that the various aspects of the present invention are directed.
In a first aspect the present invention provides improved treatment compositions for the control of undesired pests prone to infest fruit crops.
In a second aspect the present invention provides improved treatment regimens for the control of undesired pests prone to infest fruit crops, which regimens comprise the use of and application of the improved treatment compositions according to the first aspect of the invention.
According to a third aspect, the present invention provides more environmentally acceptable compositions and methods for the control of undesired pests prone to infest fruit crops.
These and further aspects of the invention will become more evident from a careful review of the following specification.
In one aspect the present invention provides a mixture or blend of a first pesticidally effective compound, O,O-dimethyl S-phthalimidomethyl phosphorodithioate, or identified by the following chemical structure (I):
which may also optionally provided as an agronomically or nonagronomically suitable salt thereof, the foregoing first said compound or salt thereof being hereinafter interchangeably referred to as “phosmet”, in combination with a second pesticidally effective compound, namely at least one benzoylurea based chitin inhibiting compound and especially preferably wherein said chitin inhibiting compound is one or more of (RS)-1-[3-chloro-4-(1,1,2-trifluoro-2-trifluoromethoxyethoxy)phenyl]-3-(2,6-difluorobenzoyl)urea or suitable salt forms thereof, and 1-(2-chlorobenzoyl)-3-(4-trifluoromethoxyphenyl)urea or suitable salt forms thereof, any of the foregoing which combination has been observed by the present inventors to provide a synergistically effective benefit in the control of undesired pests prone to infest fruit crops, and especially Codling moths which may be present on or within such fruit crops.
Other compounds useful as the at least one benzoylurea based chitin inhibiting compound include one or more of the following: 1-[2-chloro-3,5-bis(trifluoromethyl)phenyl]-3-(2,6-difluorobenzoyl)urea, also known as “bistrifluoron”; [3,5-dichloro-4-(3-chloro-5-trifluoromethyl-2-pyridyloxy)phenyl]-3-(2,6-difluorobenzoyl)urea, also known as “chlorfluazuron”; 1-(4-chlorophenyl)-3-(2,6-difluorobenzoyl)urea, also known as “diflubenzuron”; the (E-) and (Z-) isomers of 1-{α-[(EZ)-4-chloro-α-cyclopropylbenzylideneaminooxy]-p-tolyl}-3-(2,6-difluorobenzoyl)urea, also known as “flucycloxuron”; 1-[4-(2-chloro-a,a,a-trifluoro-p-tolyloxy)-2-fluorophenyl]-3-(2,6-difluorobenzoyl)urea, also known as “flufenoxuron”; 1-[3,5-dichloro-4-(1,1,2,2-tetrafluoroethoxy)phenyl]-3-(2,6-difluorobenzoyl)urea, also known as “hexaflumuron”; (RS)-1-[2,5-dichloro-4-(1,1,2,3,3,3-hexafluoropropoxy)phenyl]-3-(2,6-difluorobenzoyl)urea, also known as “lufenuron”; 1-{3,5-dichloro-2-fluoro-4-[(RS)-1,1,2,3,3,3-hexafluoropropoxy]phenyl}-3-(2,6-difluorobenzoyl)urea, also known as “noviflumuron”; 1-(3,5-dichloro-2,4-difluorophenyl)-3-(2,6-difluorobenzoyl)urea, also known as “teflubenzuron”; of which however, the use of one or both of (RS)-1-[3-chloro-4-(1,1,2-trifluoro-2-trifluoromethoxyethoxy)phenyl]-3-(2,6-difluorobenzoyl)urea or suitable salt forms thereof (also known as, and hereinafter interchangeably referred to as “novaluron”); and 1-(2-chlorobenzoyl)-3-(4-trifluoromethoxyphenyl)urea or suitable salt forms thereof (also known as, and hereinafter interchangeably referred to as “triflumuron”) is particularly preferred.
The forgoing compound (I), phosmet, is presently commercially available from the Gowan Co. (Yuma, Ariz.) under the tradename Imidan® and is a typically classified within the general class of pesticidal compounds typically identified as organophosphates.
The (RS)-1-[3-chloro-4-(1,1,2-trifluoro-2-trifluoromethoxyethoxy)phenyl]-3-(2,6-difluorobenzoyl)urea, or “novaluron” may be represented by the following chemical structure (II):
which may optionally be applied as an agronomically or a nonagronomically acceptable salt form thereof. This compound is presently commercially available from Makhteshim Agan of North America, Inc., New York, N.Y.) under the tradename Rimon® and is typically classified as an insect growth regulator, or as a chitin inhibitor.
The 1-(2-chlorobenzoyl)-3-(4-trifluoromethoxyphenyl)urea, or “triflumuron” may be represented by the following chemical structure (III):
which may optionally be applied as an agronomically or nonagronomically acceptable salt form thereof. This compound is presently commercially available from a variety of suppliers.
The present inventors had surprisingly observed that when these two materials, viz, phosmet and at least one benzoylurea based chitin inhibiting compound, and especially one or both of the preferred novaluron and/or triflumuron compounds, were combined with one another and/or concurrently present on plant part, especially a fruit crop or fruit tree, notwithstanding completely different modes of operation in which they provided a pest regulating effect, an unexpected improvement in the overall control of undesired insect pests, particularly of Codling moths, was observed. Such a result was observed, although such a result was unexpected.
Advantageously the inventors' discovery now permits for the use of reduced amounts of phosmet and at least one benzoylurea based chitin inhibiting compound which of provides improved treatment regimens for the control of undesired pests prone to infest fruit crops, as reduced amounts of one or both of the phosmet and/or the at least one benzoylurea based chitin inhibiting compound may now be applied without compromising the expectation of satisfactory control of pests in and among the fruit crop.
Alternately thereto, or in addition thereto, the inventors' discovery may provide improvements in treatment regimens in the treatment of fruit crops, as reduced amounts of the active constituents, namely one or both of the O,O-dimethyl S-phthalimidomethyl phosphorodithioate (and/or salts), viz., “phosmet”, and/or the at least one benzoylurea based chitin inhibiting compound (and particularly, the (RS)-1-[3-chloro-4-(1,1,2-trifluoro-2-trifluoromethoxyethoxy)phenyl]-3-(2,6-difluorobenzoyl)urea (and/or salts thereof), and/or the 1-(2-chlorobenzoyl)-3-(4-trifluoromethoxyphenyl)urea (and/or salts thereof)) may permit for either a reduced frequency of treatment of the fruit crops or fruit trees, either before and/or during and/or after the growth period of the fruit crops on said fruit trees, or require reduced frequency of treatment applications of the said active constituents, as well as potentially permitting for both reduced frequency of treatment of the fruit crops or fruit trees as well as the use of relatively reduced amounts of the active constituents as compared to prior art treatment regimens which had applied in separate application steps but in which both the phosmet and the at least one benzoylurea based chitin inhibiting compound were applied together or in the same application treatment step.
The inventors' discovery also has important environmental benefits as well. The inventors' discovery permits for the possible reduction in the number of application steps or the reduction in the amount of treatment compositions which need be applied to fruit crops in order to provide a satisfactory pesticidal benefit.
The present invention thus improved treatment compositions for the control of undesired pests prone to infest fruit crops, especially pome fruit crops (e.g., apples, pears). Such improved treatment compositions may comprises at least one of phosmet or at least one benzoylurea based chitin inhibiting compound but preferably comprise both in a single compositions. It is to be understood that the present invention contemplates a method whereby pesticidal effect of amounts of one of phosmet or at least one benzoylurea based chitin inhibiting compound or applied from separate compositions, but that sufficient amounts of one or both of phosmet or at least one benzoylurea based chitin inhibiting compound are nonetheless concurrently present upon a fruit crop and/or fruit tree in order to provide the improved synergistic benefits described herein. The invention thus specifically provides for compositions comprising both of phosmet and at least one benzoylurea based chitin inhibiting compound which include, without limitation concentrate compositions, pre-mixture compositions, tank-mixed compositions comprising each of phosmet and at least one benzoylurea based chitin inhibiting compound which simultaneously present when applied to a fruit crop and/or fruit tree grown for, or bearing a fruit crop. The invention further also specifically provides for separate compositions, which comprise only one of either the phosmet or the at least one benzoylurea based chitin inhibiting compound which compositions may also be, without limitation, concentrate compositions, pre-mixture compositions, or other product forms which may be separately applied to a fruit crop and/or fruit tree grown for, or bearing a fruit crop. In this latter instance, one of either the phosmet or at least one benzoylurea based chitin inhibiting compound is separately applied from its respective composition but is nonetheless each of the phosmet and the at least one benzoylurea based chitin inhibiting compound are simultaneously present upon a fruit crop and/or fruit tree grown for, or bearing a fruit crop.
Advantageously, when either only one of, or both of phosmet and at least one benzoylurea based chitin inhibiting compound are provided in a composition which may include one or more adjunct materials, e.g. solid carriers, liquid carriers, which may further optionally include one or more for the adjunct materials which can provide a technical benefit, e.g., surfactants, further biologically active materials, and the like. Such a composition may be provided as a premix composition or concentrate composition containing one or both of phosmet and at least one benzoylurea based chitin inhibiting compound, which is intended to be diluted or admixed to further materials in order to form a treatment composition therefrom suited for application to a fruit crop or fruit tree. Alternately such a composition may be supplied in a ready-to-use form requiring no further dilution or ad mixing in order to form a suitable treatment composition therefrom. Preferred embodiments of the inventive compositions or run include both of phosmet and at least one benzoylurea based chitin inhibiting compound, in suitable amounts such that in any treatment composition formed therefrom and prior to application, advantageously each out of the phosmet and at least one benzoylurea based chitin inhibiting compound are present in respective weight ratios of between 1:100 to 100:1 of the former to the latter said compound. More preferred respective weight ratios of the phosmet to the at least one benzoylurea based chitin inhibiting compound include one or more of the following respective weight ratios: 1:99, 2:98; 5:95; 7.5:92.5; 10:90; 12.5:87.5; 15:85; 17.5:82.5; 20:80; 22.5:77.5; 25:75; 27.5:72.5; 30:70; 32.5:67.5; 35:65; 37.5:62.5; 40:60; 42.5:57.5; 45:55; 47.5:52.5; 50:50; 52.5:47.5; 55:45; 57.5:42.5; 60:40; 62.5:37.5; 65:35; 67.5:32.5; 70:30; 72.5:27.5; 75:25; 77.5:22.5; 80:20; 82.5:17.5; 85:15; 87.5:12.5; 90:10; 92.5:7.5; 95:5; 97.5:2.5; 98:2 and 99:1.
Alternatively, wherein the phosmet and the at least one benzoylurea based chitin inhibiting compound are used in providing or forming two separate treatment compositions which are separately applied to a fruit crop and/or fruit tree grown for or bearing a fruit crop from separate compositions, advantageously the ultimate weight ratio of the phosmet to the at least one benzoylurea based chitin inhibiting compound which is applied from separate compositions falls within the above preferred respective weight ratios. In such a situation, the total weight of the two separate treatment compositions, one of each which separately includes one of either the phosmet or the at least one benzoylurea based chitin inhibiting compound may be used to calculate the total amount of the two separate compositions applied per unit coverage area, e.g, plant, tree, ground area, etc. which it thus considered a treatment composition. Thus, the total amounts of the phosmet and of the at least one benzoylurea based chitin inhibiting compound may be calculated on such a combined weight basis, and therefrom the respective weight ratios of these compounds can be determined by routine analytical methods, or alternately by routine calculation. In the case the latter situation, wherein two separate treatment compositions are used to separately apply one of either the phosmet or the at least one benzoylurea based chitin inhibiting compound, and a further separate treatment composition is used to apply the other of the phosmet or the at least one benzoylurea based chitin inhibiting compound, it is only required that both the phosmet and the at least one benzoylurea based chitin inhibiting compound be simultaneously present upon a fruit crop and/or fruit tree grown for, or bearing a fruit crop. This recognizes that a time interval may be permitted to elapsed between the application of each of the two foregoing separate treatment compositions. In particularly preferred embodiments, the two foregoing separate treatment compositions and the time interval between their applications is minimize, is preferably less than 48 hours there between, and in order of preference time interval between the application of the separate treatment compositions is not more than 42, 40, 38, 36, 34, 32, 30, 28, 26, 24, 22, 20, 18, 17, 16, 15, 14, 13, 12, 11, 10, 9, 8, 7, 6, 5, 4, 3, 2, 1, 0.75, 0.5, and 0.25 hours. Such decreased amounts of time between applications of the said foregoing separate treatment compositions improves the retention of the first of the applied compounds, either the phosmet or the at least one benzoylurea based chitin inhibiting compound prior to the application of the other of these said compounds which had not been applied. Consequently, such improves the likelihood of an improved efficacy against undesired insect pests, as described elsewhere in this specification. Again, however as noted previously in particularly preferred embodiments both of the phosmet and the at least one benzoylurea based chitin inhibiting compound are simultaneously applied within one treatment application step or treatment application process step such that both of the phosmet and the at least one benzoylurea based chitin inhibiting compound or simultaneously or concurrently delivered to a fruit crop and/or fruit tree grown for, or bearing a fruit crop. Such simultaneous application reduces the likelihood of an applied treatment composition being washed away such as my rainwater, spraying of further treatment compositions, including that of a subsequent treatment composition as may be applied to the a fruit crop and/or fruit tree grown for, or bearing a fruit crop.
The amount or application rate of the phosmet may be varied according to the needs of the particular environmental conditions, the type of fruit crop being grown. It is well recognized that such environmental conditions vary widely between geographic regions, as well as seasons of the year. The phosmet may be applied to a fruit crop and/or fruit tree grown for, or bearing a fruit crop, in any amounts which is found to be effective in providing a desired degree of control of unwanted insect pests, when said compound is concurrently present upon the fruit crop and/or fruit tree grown for, or bearing a fruit crop with an effective amount of the at least one benzoylurea based chitin inhibiting compound. Advantageously the phosmet may be applied to a fruit crop and/or fruit tree grown for, or bearing a fruit crop, at delivery rates of 0.01 lbs.-10 lbs. per acre of crop treated, preferably at delivery rates of 0.5 to 5 lbs. per acre of crop being treated, and especially preferably between 1 and 3.5 lbs. per acre of crop being treated. The phosmet may be applied to a fruit crop and/or fruit tree grown for, or bearing a fruit crop, either a single time during the year or growing season for the fruit crop but is often advantageously applied two or more times to the fruit crop and/or fruit tree grown for, or bearing a fruit crop, during the growing season. The at least one benzoylurea based chitin inhibiting compound may be applied according to similar guidelines, as it is similarly recognized that the amount or application rate of the at least one benzoylurea based chitin inhibiting compound may be varied according to the needs of the particular environmental conditions, the type of fruit crop being grown. The at least one benzoylurea based chitin inhibiting compound may be applied to a fruit crop and/or fruit tree grown for, or bearing a fruit crop, in any amounts which is found to be effective in providing a desired degree of control of unwanted insect pests, when said compound is concurrently present upon the fruit crop and/or fruit tree grown for, or bearing a fruit crop with an effective amount of the phosmet. Advantageously the at least one benzoylurea based chitin inhibiting compound may be applied to a fruit crop and/or fruit tree grown for, or bearing a fruit crop, at delivery rates of 0.01 to 10 lbs. per acre of crop being treated, preferably at delivery rates of 0.05-5 lbs. per acre of crop being treated. The at least one benzoylurea based chitin inhibiting compound may be applied to the said may be applied to a fruit crop and/or fruit tree grown for, or bearing a fruit crop, either a single time during the year or growing season for the fruit crop but is often advantageously applied two or more times to the fruit crop and/or fruit tree grown for, or bearing a fruit crop, during the growing season. By way of nonlimiting example, application rates to specific crops include those demonstrated in one or more of the following examples described hereafter; such include preferred application rates as well as application regimens. It is of course to be understood that other application rates, timing frequencies, and the like may be practiced in order to enjoy the full benefits of the present invention.
Any of the compositions of the invention, including any prepared treatment composition of the invention, which includes at least one of phosmet or at least one benzoylurea based chitin inhibiting compound, but which preferably simultaneously include both phosmet and at least one benzoylurea based chitin inhibiting compound, may include still further optional constituents which will be recognized as being commonly encountered adjunct materials useful in pesticidal compositions, particularly largely aqueous pesticidal compositions which are adapted to be applied by conventional spraying methods and machinery. Such include, by way of non-limiting example: surfactants, solid carriers, liquid carriers, safeners, oils, wetters, dispersants, emulsifiers, preservatives, antifreeze agents, solvents, oils, fillers, colorants, carriers, antifoams, evaporation inhibitors, pH regulators, viscosity regulators, as well as one or more further adjunct materials which can provide a technical or biological benefit.

Specific examples of C10-C22-fatty acid esters are esters obtained by reacting glycerol or glycol with the C10-C22-fatty acids as they exist, for example, in oils from oil-plant species, or C1-C20-alkyl-C10-C22-fatty acid esters as can be obtained, for example, by transesterification of the above-mentioned glycerol- or glycol-C10-C22-fatty acid esters with C1-C20-alcohols (for example methanol, ethanol, propanol or butanol). Preferred C1-C20-alkyl-C10-C22-fatty acid esters are the methyl, ethyl, propyl, butyl, 2-ethylhexyl and dodecyl esters. Preferred glycol- and glycerol-C10-C22-fatty acid esters are the uniform or mixed glycol esters and glycerol esters of C10-C22-fatty acids, in particular of those fatty acids which have an even number of carbon atoms, for example erucic acid, lauric acid, palmitic acid and, in particular, C18-fatty acids such as stearic acid, oleic acid, linolic acid or linolenic acid.
The application rates for one or more oils, when in a treatment composition of the invention, may vary widely but in general are advantageously from about 0.001 to about 50% by weight, preferably 0.01-40% by weight, based on the total weight of the composition of which one or more such oils form a part.
Treatment compositions of the invention may include one or more non-aqueous solvents in effective amounts. Representative solvents include: aromatic hydrocarbons, preferably the fractions containing 8 to 12 carbon atoms such as mixtures of alkylbenzenes, typically xylene mixtures or alkylated naphthalenes; aliphatic and cycloaliphatic hydrocarbons such as paraffins, cyclohexane or tetrahydronaphthalene; alcohols such as ethanol, propanol or butanol; glycols and their ethers and esters such as propylene glycol or dipropylene glycol ether; ketones such as cyclohexanone, isophorone or diacetone alcohol; strongly polar solvents such as N-methyl-2-pyrrolidone, dimethyl sulfoxide, and in some cases also silicone oils. While such non-aqueous solvents may be omitted, when present they may be included in any effective amounts. Representative amounts are from about 0.001 to about 95% by weight, preferably from about 5% to about 90% by weight, based on the total weight of a treatment composition within which the non-aqueous solvent is present, or of which the non-aqueous solvent forms a part.
The treatment compositions of the invention may include solid carriers in effective amounts. Non-limiting examples of suitable carriers include materials known to the relevant art and are solid carriers typically used for dusts and dispersible powders are usually natural mineral fillers such as calcite, talcum, kaolin, montmorillonite or attapulgite. To improve the physical properties it is also possible to add highly dispersed silicic acid or highly dispersed absorbent polymers. Suitable granulated adsorptive carriers are porous types, including pumice, broken brick, sepiolite or bentonite; and suitable nonsorbent carriers are materials such as calcite or sand. In addition, innumerable pregranulated materials of inorganic or organic origin may be used, especially dolomite or pulverised plant residues. When present, such solid carriers may be included in a treatment composition any effective amounts. Representative amounts are from about 0.001 to about 95% by weight, preferably from about 5 to about 90% by weight, based on the total weight of the sulfonylurea based herbicide treatment preparation with which the solid carriers is present, or of which the solid carriers forms a part.
In certain product formats of the treatment composition, a major amount of water may be added to the forgoing constituents present in a treatment composition such as in a concentrated form, or pre-mix form of a treatment composition in order to form a tank mix or working solution or dispersion of the said forgoing constituents which in such a form is particularly adapted to be delivered by spraying. Water may be used as a carrier and/or as a solvent for one or more of the constituents present in a treatment composition, or may be both a solvent and carrier.
It is to understood that a treatment composition within the scope of this invention can exist not only as either phosmet without any further constituents, or at least one benzoylurea based chitin inhibiting compound without any further constituents, or a mixture consisting solely of phosmet and at least one benzoylurea based chitin inhibiting compound without further constituents, but usually product forms of treatment compositions may further include one or more further adjuncts as described herein, as well as further agrochemically active constituents, additives and/or customary formulation auxiliaries not described herein but known to the skilled formulator. Any such further adjuncts and/or further agrochemically active constituents, additives and/or customary formulation auxiliaries may be added to either the phosmet and/or at least one benzoylurea based chitin inhibiting compound prior at any time prior to the application of either the phosment or the at least one benzoylurea based chitin inhibiting compound or both, to a fruit crop or fruit tree. For example, such a treatment composition may be formed by combining at least one of phosment or at least one benzoylurea based chitin inhibiting compound, but preferably both, with a suitable carrier, e.g, water, optionally with one or more adjuncts with or without one or more further agrochemically active constituents, additives and/or customary formulation auxiliaries in order to form a treatment composition therefrom. Any treatment composition may be applied in the customary manner. Any treatment composition of the invention can be formulated in various ways, depending on the prevailing biological and/or chemical-physical parameters. The following are examples of general possibilities for formulations: wettable powders (WP), water-soluble concentrates, emulsifiable concentrates (EC), aqueous solutions (SL), emulsions (EW) such as oil-in-water and water-in-oil emulsions, sprayable solutions or emulsions, suspension concentrates (SC), oil- or water-based dispersions, suspoemulsions, dusts (DP), seed-dressing materials, granules for soil application or for broadcasting, or water-dispersible granules (WG), ULV formulations, microcapsules or waxes.
Wettable powders (sprayable powders) are products which are uniformly dispersible in water and which, in addition to at least the phosmet or the at least one benzoylurea based chitin inhibiting compound but preferably both, frequently also comprise ionic or nonionic surfactants (wetters, dispersants), for example polyoxethylated alkylphenols, polyethoxylated fatty alcohols or fatty amines, alkanesulfonates or alkylbenzenesulfonates, sodium lignosulfonate, sodium 2,2′-dinaphthylmethane-6,6′-disulfonate, sodium dibutylnaphthalenesulfonate or else sodium oleoylmethyltauride, in addition to a diluent or inert material.
Emulsifiable concentrates of treatment compositions of the invention may also be formed using conventional techniques, and used according to treatment methods of the invention. For example, at least one of phosmet and novaluran are dissolved in an organic solvent, for example butanol, cyclohexanone, dimethylformamide, xylene or else higher-boiling aromatics or hydrocarbons with addition of one or more ionic or nonionic surfactants (emulsifiers) to form an emulsifiable concentrate. Non-limiting examples of emulsifiers which may be used are: calcium salts of alkylarylsulfonic acids, such as calcium dodecylbenzene sulfonate, or nonionic emulsifiers such as fatty acid polyglycol esters, alkylaryl polyglycol ethers, fatty alcohol polyglycol ethers, propylene oxide/ethylene oxide condensates, alkyl polyethers, sorbitan fatty acid esters, polyoxyethylene sorbitan fatty acid esters or polyoxethylene sorbitol esters. The emulsifiable concentrate can be later diluted or dispersed prior to use in a suitable carrier, and used as a treatment composition.
Typically, dusts are obtained by grinding the sulfonylurea based herbicide with finely divided solid materials, for example talc, natural clays such as kaolin, bentonite and pyrophyllite, or diatomaceous earth.
Suspension concentrates (SC) can be water- or oil-based. They can be prepared, for example, by wet grinding by means of commercially available bead mills and, if appropriate, addition of further surfactants as they have already been mentioned for example above in the case of the other formulation types.
Emulsions, for example oil-in-water emulsions (EW), can be prepared for example by means of stirrers, colloid mills and/or static mixers using aqueous organic solvents and, if appropriate, further surfactants as have already been mentioned for example above in the case of the other formulation types.
Microemulsions may also be used as a product form for the inventive compositions, which may be produced according to convention methods know to the art.
Similarly microencapsulated product forms may also be used as a product form for the inventive compositions, which may be produced according to convention methods know to the art.
Granules can be prepared either by spraying one or both of the phosmet or at least one benzoylurea based chitin inhibiting compound and any further optional constituents (where appropriate) onto adsorptive, granulated inert material or by applying one or both of the phosmet or at least one benzoylurea based chitin inhibiting compound and any further optional constituents (where appropriate) to the surface of carriers such as sand, kaolites or granulated inert material with the aid of binders, for example polyvinyl alcohol, sodium polyacrylate or else mineral oils. Granulation may occur in the manner conventionally used for the production of fertilizer granules, if desired in a mixture with fertilizers. As a rule, water-dispersible granules are prepared by conventional processes such as spray drying, fluidized-bed granulation, disk granulation, mixing with high-speed mixers and extrusion without solid inert material, according to techniques known to the art.
Treatment compositions may be provided in a variety of product forms. In one such form a concentrated composition containing one or both phosmet and at least one benzoylurea based chitin inhibiting compound, optionally with one or more further adjunct materials, are provided in a form wherein the concentrated composition is intended to be blended or dispersed in a further fluid carrier such as water or other largely aqueous liquid, to which fluid carrier may be separately added or within which is already present one or more adjunct materials. Such is a convenient method to form a “tank mix” or other form of a treatment composition which may be ready-to-use and suitable for application onto a fruit crop and/or fruit tree.
In a still further product form, the treatment composition may also be provided in a powdered or solid form, e.g., a comminuted solid which can be dispersed into a fluid carrier or medium, in a concentrated form, which may be a solid, liquid, or a gel which is intended to be further dissolved or dispersed in a carrier medium, such as a liquid which may be pressurized or non-pressurized, e.g., water. Such a form of a treatment composition is advantageously and conveniently provided as a dispersible or dilutable concentrate composition which is then used in a “tank mix” which may optionally include further adjunct materials.
In a further product form, treatment compositions of the invention are provided as a ready-to-use product which requires no further dilution but can be directly applied to plants, or crops, viz., as a ready to use composition.
The treatment compositions of the invention may also be provided in any suitable or conventional packaging means. For example, conventional containers such as bottles, or sachets containing a solid, liquid or fluid composition enclosed within a water-soluble film may be conveniently provided particularly when the former are provided in premeasured unit dosage forms. The latter are particularly useful in avoiding the need for measuring or packaging and provides a convenient means whereby specific doses that the treatment compositions can be provided.
In a second aspect the present invention provides improved treatment regimens for the control of undesired insect pests prone to infest crops, particularly fruit crops, which regimens comprise the use of and application of the improved treatment compositions according to the first aspect of the invention. Broadly stated, in the second aspect of the invention, pesticidally effective amounts of both phosmet and at least one benzoylurea based chitin inhibiting compound are applied so to be present upon a fruit crop and/or fruit tree in order to provide particularly effective control of undesired insect pests thereon, in one or more stages of growth, e.g, eggs, larval or adult.
Nonlimiting examples of undesired insect pests which may be controlled by the inventive composition include one or more of: fireworm, gypsy moth, fruitworm, flea beetle, spanworm, leafroller, maggot, Colorado potato beetle, corn borer, budmouth, leafminer, fruitmoth, twig borer and weevil, in methods for their control in one or more stages of their growth, e.g., eggs, larval stage or adult, utilizing the inventive composition. In certain particularly preferred embodiments, there are provided methods for the control of Codling moth in one or more stages of its growth, e.g., eggs, larval stage or adult, utilizing the inventive compositions described herein.
The treatment compositions of the invention may be used in otherwise conventional application regimens or treatment processes used for the application of pesticides on crops, particularly fruit crops, e.g. fruit trees. By way of nonlimiting example, crops which may be treated using the inventive compositions include more of: blueberry, cranberry, stone fruit crops, pome fruit, potato, sweet potato, peas, nuts, including ground nuts as well as tree nuts, grapes and even alfalfa.
Non-limiting examples of equipment which may be used in conjunction with the treatment compositions of the invention include: airblast sprayers, fan driven sprayer, high velocity fan, pressurized spray heads, hand gun sprayers, sprinklers as well as other equipment known to be useful in application of treatment compositions to fruit crop and/or fruit trees.
The treatment compositions according to the invention as well as the methods according to the invention may be practiced upon virtually any plans or plant parts which may become or is susceptible to infested with, or is already undesirably infested with one or more insect pests, particularly the Codling moth. In preferred embodiments, the compositions of the invention are use to control the incidence of Codling moth on or among a fruit crop and/or fruit tree grown for or bearing a fruit crop.
Examples of fruit trees and/or fruit crops which are our advantageously treated with the treatment compositions taught herein include, but are not limited to one or more of the following: pome fruits, e.g., pears, apples, stone fruit, as well as nuts such as walnuts including English walnuts, stone fruit, crabapples, rosacea family fruits and flowers. While not listed here, further plants and crops which are to be understood to include both fruit crops as well as ornamental plants may also benefit from the inventive compositions.
As noted previously, the inventive compositions and inventive methods have been observed in the control of Codling moth (Cydia pomonella Linnaeus), and the incidence of damage to fruit crops caused thereby. However it is to be understood that the inventive compositions and methods may also be similarly effective in the control of other undesired fruit worms in the family Tortricidae, including but not limited to: grape berry moth (Endopiza viteana Clemens), and oriental fruit moth (Grapholita molesta Busck). Also as noted previously the inventive compositions and improved treatment regimens may also be used to control other undesired insect pests.
Certain preferred examples of treatment compositions, as well as certain examples of methods for controlling the presence of undesired pests in fruit, and fruit bearing trees are disclosed in the following examples.
Comparative studies of the efficacy of treatment compositions according to the invention which contained both phosmet and triflumuron, as compared to comparative compositions which included only triflumuron were undertaken. Both during and after the conclusion of the treatments with the various compositions, the incidence of fruit damage due to the incidence of Codling moth was evaluated and reported. The incidence of Codling moth damage on an untreated control sample of trees (“UTC”) was also evaluated to provide baseline results for each set of trees at each of the test locations.
The location (US State) identity of the fruit crop, tree age, size of tree sample, treatment composition, wt/wt ratio of the active constituents in the treatment composition, application volume, mode of application, number of treatment applications, and application intervals, are indicated on Table 1, following. Treatment compositions and treatment protocols are identified by an example number beginning with the letter “E”, while treatment compositions and treatment protocols according to comparative sample are identified by an example number beginning with the letter “C”. The indicated treatment compositions were formed by dispersing the indicated constituents in a larger volume of water, to provide the indicated concentrations, which were thereafter applied.
Each of the foregoing treatment protocols were initiated shortly after the fall of the fruit tree blossoms.
Evaluation of fruit damage caused by the incidence of Codling moth larvae was performed at two time intervals, a first evaluation was performed mid-season, approximately at the 1st generation stage of Codling moth development, and a second evaluation was performed at harvest, approximately at the 1st and 2nd generation stage of Codling moth development. The reported results at harvest were indicative of cumulative injury to the examined fruit. At each evaluation, approximately 100-250 fruit were collected from trees treated according to each particular treatment protocol and were closely visually evaluated for Codling moth stings and complete larval entries, either of which would dictate damage to the fruit and require its culling. The reported results of the second evaluation, which is relevant as indicating the amount of marketable fruit, are indicated on the following Table 1A, for each of the treatment compositions and treatment protocols indicated on Table 1, as “% fruit damage”. Further the % fruit damage for the untreated control sample of trees (“UTC”) was also evaluated and reported on Table 1A.
Comparative studies of the efficacy of treatment compositions according to the invention which contained both phosmet and novaluron, as compared to comparative compositions which included only novaluron or only phosmet were undertaken. Both during and after the conclusion of the treatments with the various compositions, the incidence of fruit damage due to the incidence of Codling moth was evaluated and reported. The incidence of Codling moth damage on an untreated control sample of trees (“UTC”) was also evaluated to provide baseline results for each set of trees at each of the test locations.
The location (US State) identity of the fruit crop, tree age, size of tree sample, treatment composition, application volume, mode of application, number of treatment applications, and application intervals, are indicated on Table 2, following. Treatment compositions and treatment protocols are identified by an example number beginning with the letter “E”, while treatment compositions and treatment protocols according to comparative examples are identified by an example number preceded by the letter “C”. The indicated treatment compositions were formed by dispersing the indicated constituents in a larger volume of water, to provide the indicated concentrations, which were thereafter applied.
Each of the foregoing treatment protocols were initiated shortly after the fall tree blossoms.
Evaluation of fruit damage caused by the incidence of Codling moth larvae was performed at two time intervals, a first evaluation was performed mid-season, approximately at the 1st generation stage of Codling moth development, and a second evaluation was performed at harvest, approximately at the 1st and 2nd generation stage of Codling moth development. The reported results at harvest were indicative of cumulative injury to the examined fruit. At each evaluation, approximately 100-250 fruit were collected from trees treated according to each particular treatment protocol and were closely visually evaluated for Codling moth stings and complete larval entries, either of which would dictate damage to the fruit and require its culling. The reported results of the second evaluation, which is relevant as indicating the amount of marketable fruit, are indicated on the following Table 2A, for each of the treatment compositions and treatment protocols indicated on Table 2, as “% fruit damage”. Further the % fruit damage for the untreated control sample of trees (“UTC”) was also evaluated and reported on Table 2A.
As is evident from a review of the reported results, it is surprisingly observed that many treatment compositions which included reduced amounts of phosmet with novaluron were very effective as compared to comparative treatment compositions which included only phosmet. At least equally surprising was the generally observed trend that satisfactory or improved control of Codling moth was seen to occur in treatment compositions including both phosmet with novaluron; such indicates a synergistic effect.
