Description

The invention relates to the use of particular alkoxylated vegetable oil derivatives as drift-reducing components in crop treatment compositions or to the use of particular alkoxylated vegetable oil derivatives for reducing drift in the application of crop treatment compositions, to a method for reducing drift in the application of crop treatment compositions, and to compositions for drift reduction.


Crop protection compositions are applied to agricultural production fields in a very efficient manner using spray tanks in aircraft, tractors or other equipment. In order to achieve very exact positioning of the active substances, it is necessary to obtain a very narrow spray cone and to prevent drift of the spray mist away from the target site.


The drift of the spray mist is determined essentially by the droplet size distribution. The smaller the droplets, the longer the residence time in the air and the greater their tendency to drift horizontally and to evaporate and/or to miss the target site. The literature discloses that the fine droplet fraction of <150 μm (Teske et al., 2004, The Role of Small Droplets in Classifying Drop Size Distributions, ILASS Americas 17th Annual Conference, Arlington Va.), especially <100 μm (Vermeer et al., Proc. ISAA 2013, The use of adjuvanted formulations for drift control) determines the proportion of droplets in the spray mist that contributes to the drift effect. The reduction of the fine droplet content in the spray mist is therefore crucial to reduction of drift and is therefore utilized for determination of the drift properties of a composition.


Distinct minimization of the drift effect can be achieved by addition of suitable “drift control agents” to crop protection formulations, and these bring about a decrease in the fine droplet content and hence an increase in droplet size in the spray mist. The formulations modified with “drift control agents” additionally have to be insensitive to the shear forces to which they are exposed in the spray pumps and nozzles. Good biodegradability, compatibility with other constituents of the crop protection compositions and high storage stability and thermal stability are further requirements for “drift control agents”. It is known that the rheology of aqueous compositions can be modified by addition of water-soluble polymers, for example polyacrylamides, acrylamide/acrylic acid polymers, sodium polyacrylate, carboxymethyl cellulose, hydroxyethyl cellulose, methyl cellulose, polysaccharides, natural and synthetic guar gum (U.S. Pat. No. 4,413,087, U.S. Pat. No. 4,505,827, U.S. Pat. No. 5,874,096), these leading to a shift in the droplet size spectrum toward larger droplets.


Molasses and organic thickeners have also been described as effective drift reduction agents (Pesticide Drift III; Drift Reduction with Spray Thickeners; Ware, G. W. et al.; J. of Economic Entomology 63; 1314-1316; 1970). It is additionally known that particular emulsions—via a mechanism which is not fully understood—lead to a reduced fine droplet content (Vermeer et al.; Crop Protection 44; 2013; Spray drift review: The extent to which a formulation can contribute to spray drift reduction).


Even though good results are already achieved with the known systems, there is still a need, for technical, economic and ecological reasons, to find suitable “drift control agents” which, even under practical conditions, effectively increase the droplet volumes of the aqueous compositions and reduce drift of the spray mist. Especially the conflict with crop treatment composition formulations, fertilizers and interface-active tankmix additives limits the effect of the “drift control agents”, and more robust products are needed.


It has now been found that, surprisingly, particular alkoxylated vegetable oil derivatives are suitable as drift-reducing adjuvants for crop treatment compositions and, when these crop treatment compositions are sprayed, bring about an effective increase in droplet size through a reduction in the fine droplet content in the spray mist. It has thus been found that, surprisingly, these particular alkoxylated vegetable oil derivatives are suitable for use for reducing drift in the application of crop treatment compositions.


The invention therefore provides for the use of one or more alkoxylated vegetable oil derivatives, these containing structural units derived from

  • a) vegetable oil, and
  • b) alkylene oxide, where alkylene oxide is ethylene oxide, propylene oxide, butylene oxide or mixtures of ethylene oxide and propylene oxide or mixtures of ethylene oxide and butylene oxide, and
  • c) one or more monocarboxylic acids of the formula (I)





R1—COOH  (I)

    • where R1 is unbranched or branched, saturated alkyl having 1 to 29 carbon atoms or unbranched or branched, mono- or polyunsaturated alkenyl having 2 to 29 carbon atoms,


      for reducing drift in the application of crop treatment compositions.


The invention additionally provides for the use of one or more alkoxylated vegetable oil derivatives obtainable by reaction of components a) and b) and c)

  • a) vegetable oil, and
  • b) alkylene oxide, where alkylene oxide is ethylene oxide, propylene oxide, butylene oxide or mixtures of ethylene oxide and propylene oxide or mixtures of ethylene oxide and butylene oxide, and
  • c) one or more monocarboxylic acids of the formula (I)





R1—COOH  (I)

    • where R1 is unbranched or branched, saturated alkyl having 1 to 29 carbon atoms or unbranched or branched, mono- or polyunsaturated alkenyl having 2 to 29 carbon atoms,


      for reducing drift in the application of crop treatment compositions.


The vegetable oil a) preferably comprises triglycerides, i.e. esters of glycerol and a single fatty acid or a plurality of different fatty acids Ra—COOH where Ra is a linear or branched, saturated alkyl radical having 5 to 29, preferably 7 to 21, carbon atoms, which may also contain one or more OH groups, or a linear or branched, mono- or polyunsaturated alkenyl radical having 5 to 29, preferably 7 to 21, carbon atoms, which may also contain one or more OH groups.


In the context of the present invention, the structural units derived from ethylene oxide are structural units —C2H4O—, the structural units derived from propylene oxide are structural units —C3H6O—, and the structural units derived from butylene oxide are structural units —C4H8O—, which are also referred to hereinafter simply as EO, PO and BO units respectively.


“Crop treatment compositions” in the context of the invention are preferably understood to mean compositions containing one or more substances selected from the group consisting of pesticides, phytohormones, preferably growth regulators, biological control agents, salts that can be deployed in water, preferably fertilizers or plant nutrients, or fungicidal copper compounds, and repellents. The one or more substances just mentioned, selected from the group consisting of pesticides, phytohormones, preferably growth regulators, biological control agents, salts that can be deployed in water, preferably fertilizers or plant nutrients, or fungicidal copper compounds, and repellents, are referred to in the context of the present invention as “agrochemical substances”.


“Drift” in the context of the invention is understood to mean the effect that the spraying of the crop treatment composition forms small droplets which are borne beyond the area to be treated, and can thus make the spraying less effective or even harmful to adjacent areas and crops.


In addition to the drift, relatively small droplets have a tendency to increased vaporization, which can lead to reduced availability of the active ingredient in the target area.


In the context of the present invention, “drift reduction” or “reducing drift” are preferably understood to mean the reduction of the proportion of fine droplets having a diameter of <105 μm in the spray mist compared to the application of a composition which does not contain the alkoxylated vegetable oil derivatives, preferably by at least 10% and more preferably by at least 25%.


It is known that the presence of particular substances in aqueous spray liquors increases the fine droplet content in the spray mist compared to aqueous spray liquors which do not contain these substances. If alkoxylated vegetable oil derivatives used in accordance with the invention are added to these spray liquors having an elevated fine droplet content, the relative reduction in drift may be even much higher than that specified above.


“Application” of a crop treatment composition in the form of a spray liquor containing one or more agrochemical substances in the context of the invention is understood to mean the application of an aqueous spray liquor containing one or more agrochemical substances to the plants to be treated or the site thereof.


Preferably, the one or more alkoxylated vegetable oil derivatives used in accordance with the invention contain structural units derived from or obtainable by reaction of

  • c) 0.1% to 40% by weight of one or more monocarboxylic acids of the formula (I)





R1—COOH  (I)

    • where R1 is unbranched or branched, saturated alkyl having 1 to 29 carbon atoms or unbranched or branched, mono- or polyunsaturated alkenyl having 2 to 29 carbon atoms.


In the alkoxylated vegetable oil derivatives used in accordance with the invention, said proportions of components a), b) and c) (in % by weight) are based on the total amount of the components as used for preparation of the alkoxylated vegetable oil derivatives. They do not relate to the final composition of the alkoxylated vegetable oil derivatives, which differs slightly therefrom as a result of elimination of water released in the condensation.

The hydrolysis number of the one or more alkoxylated vegetable oil derivatives is preferably between 70 and 150 mg KOH/g and more preferably between 100 and 120 mg KOH/g.


The hydrolysis number is determined using the method described in DIN EN ISO 3618.


The acid number of the one or more alkoxylated vegetable oil derivatives is preferably less than 10 mg KOH/g and more preferably less than 7 mg KOH/g.


The acid number is determined using the method described in DIN EN ISO 2114.


Especially preferred are the alkoxylated vegetable oil derivatives detailed in the examples section.

In a further preferred embodiment of the invention, the one or more vegetable oil derivatives are obtained by reaction of components a) and b) and c).


The one or more alkoxylated vegetable oil derivatives may be used in all standard formulation types, preferably in liquid formulations. In principle, the compounds can also be introduced into solid formulations.


A preferred embodiment of the invention is the use of the one or more alkoxylated vegetable oil derivatives for reducing drift in the application of crop treatment compositions as a tankmix additive, meaning that the one or more alkoxylated vegetable oil derivatives are not added until directly prior to deployment of a spray liquor produced from a concentrated formulation.


Another preferred embodiment of the invention is the use of the one or more alkoxylated vegetable oil derivatives for reducing drift in the application of crop treatment compositions as an in-can variant, meaning that the one or more alkoxylated vegetable oil derivatives are already incorporated into a concentrated formulation together with the ingredients of the crop treatment composition and are deployed as spray liquor diluted with water.

These spray liquors used in the inventive use preferably contain one or more agrochemical substances.


If a crop treatment composition contains two or more alkoxylated vegetable oil derivatives, the stated amount should be understood as the total content of all the alkoxylated vegetable oil derivatives.


The radical definitions, value ranges and elucidations given above, in general terms or in areas of preference, can be combined with one another as desired, i.e. including combinations between the particular ranges and ranges of preference.


The mechanism of action of the one or more alkoxylated vegetable oil derivatives for reducing drift in the application of crop treatment compositions is basically independent of the nature of the agrochemical substance used. However, the selection of the optimal alkoxylation level of the one or more alkoxylated vegetable oil derivatives for maximum drift reduction on application can be influenced by any cloud point-lowering substances present in the crop treatment compositions, for example active ingredient salts or other salts.


The one or more alkoxylated vegetable oil derivatives can be used in the production of crop treatment compositions. The result here is compositions used in accordance with the invention that contain one or more alkoxylated vegetable oil derivatives and one or more agrochemical substances.

Standard formulation forms for crop treatment compositions are, for example, water-soluble liquids (SL), emulsion concentrates (EC), emulsions in water (EW), suspension concentrates (SC, SE, FS, OD), water-dispersible granules (WG), granules (GR) and capsule concentrates (CS). These and further possible formulation types are described, for example, by Crop Life International and in Pesticide Specifications, Manual on development and use of FAO and WHO specifications for pesticides, FAO Plant Production and Protection Papers—173, prepared by the FAO/WHO Joint Meeting on Pesticide Specifications, 2004, ISBN: 9251048576.


The crop treatment compositions may optionally contain action-improving adjuvants. An adjuvant in this context is a component which enhances the biological effect of the formulation, without the component itself having any biological effect. Examples of adjuvants are penetrants, for example vegetable oils, for example rapeseed oil, sunflower oil, mineral oils, for example paraffin oils, alkyl esters of vegetable fatty acids, for example rapeseed oil methyl ester or soya oil methyl ester, or alkanol alkoxylates and/or spreaders, for example alkylsiloxanes and/or salts, for example organic or inorganic ammonium or phosphonium salts, for example ammonium sulfate or diammonium hydrogenphosphate and/or retention promoters, for example dioctyl sulfosuccinate or hydroxypropylguar polymers and/or humectants, for example glycerol and/or fertilizers, for example ammonium-, potassium- or phosphorus-containing fertilizers and/or agents which promote sticking to the leaf surface.


Optionally, the crop treatment compositions may contain auxiliaries, preferably in combination with the abovementioned adjuvants. The auxiliaries may, for example, be extenders, solvents, spontaneity promoters, carriers, emulsifiers, dispersants, antifreezes, biocides and/or thickeners.


The crop treatment compositions are produced in a known manner, for example by mixing the active ingredients with auxiliaries, for example extenders, solvents and/or solid carriers and/or further auxiliaries, for example surfactants. The crop treatment compositions are produced as formulations either in suitable facilities or else before or during application.


Auxiliaries used may be those substances which are suitable for imparting particular properties, such as particular physical, technical and/or biological properties, to the formulation of the active ingredient or to the use forms prepared from these formulations (for example ready-to-use crop protection compositions such as spray liquors or seed dressing products).


Suitable extenders are, for example, water, polar and nonpolar organic chemical liquids, for example from the classes of the aromatic and nonaromatic hydrocarbons (such as paraffins, alkylbenzenes, alkylnaphthalenes, chlorobenzenes), the alcohols and polyols (which may optionally also be substituted, etherified and/or esterified), the ketones (such as acetone, cyclohexanone), esters (including fats and oils) and (poly)ethers, the unsubstituted and substituted amines, amides, lactams (such as N-alkylpyrrolidones) and lactones, the sulfones and sulfoxides (such as dimethyl sulfoxide).


In principle, it is possible to use any suitable solvents. Examples of suitable solvents are aromatic hydrocarbons, for example xylene, toluene or alkylnaphthalenes, chlorinated aromatic or aliphatic hydrocarbons, for example chlorobenzene, chloroethylene or methylene chloride, aliphatic hydrocarbons, for example cyclohexane, paraffins, mineral oil fractions, mineral and vegetable oils, alcohols, for example methanol, ethanol, isopropanol, butanol or glycol and the ethers and esters thereof, ketones, for example acetone, methyl ethyl ketone, methyl isobutyl ketone or cyclohexanone, strongly polar solvents such as dimethylformamide and dimethyl sulfoxide, and also water.


In principle, it is possible to use any suitable carriers. Useful carriers especially include: for example ammonium salts and natural rock flour such as kaolins, aluminas, talc, chalk, quartz, attapulgite, montmorillonite or diatomaceous earth, and synthetic rock flour such as finely divided silica, aluminum oxide and natural or synthetic silicates, resins, waxes and/or solid fertilizers. It is likewise possible to use mixtures of such carriers. Useful carriers for granules include: for example crushed and fractionated natural rocks such as calcite, marble, pumice, sepiolite, dolomite, and synthetic granules of inorganic and organic flours, and also granules of organic material such as sawdust, paper, coconut shells, corn cobs and tobacco stalks.


It is also possible to use liquefied gaseous extenders or solvents. Especially suitable are those extenders or carriers which are gaseous at standard temperature and under standard pressure, for example aerosol propellants such as halohydrocarbons, or else butane, propane, nitrogen and carbon dioxide.


Examples of emulsifiers and/or foam formers, dispersants or wetting agents with ionic or nonionic properties, or mixtures of these surfactants, are salts of polyacrylic acid, salts of lignosulfonic acid, salts of phenolsulfonic acid or naphthalenesulfonic acid, polycondensates of ethylene oxide with fatty alcohols or with fatty acids or with fatty amines, with substituted phenols (preferably alkylphenols or arylphenols), salts of sulfosuccinic esters, taurine derivatives (preferably alkyl taurates), phosphoric esters of polyethoxylated alcohols or phenols, fatty acid esters of polyols, and derivatives of the compounds containing sulfates, sulfonates and phosphates, for example alkylaryl polyglycol ethers, alkyl sulfonates, alkyl sulfates, arylsulfonates, protein hydrolyzates, lignosulfite waste liquors and methyl cellulose. The presence of a surfactant is advantageous when one of the active ingredients and/or one of the inert carriers is insoluble in water and when application is effected in water.


Further auxiliaries which may be present in the formulations and the use forms derived therefrom are dyes such as inorganic pigments, for example iron oxide, titanium oxide and Prussian Blue, and organic dyes such as alizarin dyes, azo dyes and metal phthalocyanine dyes, and nutrients and trace nutrients such as salts of iron, manganese, boron, copper, cobalt, molybdenum and zinc.


Additional components may be stabilizers, such as cold stabilizers, preservatives, antioxidants, light stabilizers, or other agents which improve chemical and/or physical stability. In addition, foam formers or defoamers may be present.


In addition, the formulations and the use forms derived therefrom may also comprise, as additional auxiliaries, stickers such as carboxymethyl cellulose and natural and synthetic polymers in the form of powders, granules or latices, such as gum arabic, polyvinyl alcohol and polyvinyl acetate, or else natural phospholipids such as cephalins and lecithins and synthetic phospholipids. Further possible auxiliaries are mineral and vegetable oils.


It is possible if appropriate for still further auxiliaries to be present in the formulations and the use forms derived therefrom. Examples of such additives are fragrances, protective colloids, binders, adhesives, thickeners, thixotropic agents, penetrants, retention promoters, stabilizers, sequestrants, complexing agents, humectants, spreaders.


In general, the agrochemical substances can be combined with any solid or liquid additive which is commonly used for formulation purposes.


Useful retention promoters include all those substances which reduce dynamic surface tension, for example dioctyl sulfosuccinate, or increase viscoelasticity, for example hydroxypropylguar polymers.


Useful penetrants in the present context are all those substances which are typically used to improve the penetration of agrochemical substances into plants.


Penetrants are defined in this context by their ability to penetrate from the (generally aqueous) application liquor and/or from the spray coating into the cuticle of the plant and hence increase the mobility of active ingredients in the cuticle. The method described in the literature (Baur et al., 1997, Pesticide Science 51, 131-152) can be used to determine this property. Examples include alcohol alkoxylates, for example coconut fat ethoxylate (10) or isotridecyl ethoxylate (12), fatty acid esters, for example rapeseed oil methyl ester or soya oil methyl ester, fatty amine alkoxylates, for example tallowamine ethoxylate (15) or ammonium salts and/or phosphonium salts, for example ammonium sulfate or diammonium hydrogenphosphate.


The crop treatment compositions contain preferably between 0.00000001% and 98% by weight of agrochemical substances, more preferably between 0.01% and 95% by weight of agrochemical substances and especially preferably between 0.5% and 90% by weight of agrochemical substances, based on the weight of the crop treatment compositions.


The content of agrochemical substances in the use forms (crop protection compositions) prepared from the crop treatment compositions can vary within wide limits. The concentration of the agrochemical substances in the use forms, especially in the spray liquors, may typically be between 0.00000001% and 95% by weight of agrochemical substance, preferably between 0.00001% and 5% by weight of agrochemical substance, more preferably between 0.00001% and 1% by weight of agrochemical substance and especially preferably between 0.001% and 1% by weight of agrochemical substance, based on the weight of the use form, especially of the spray liquor. Application is accomplished in a customary manner appropriate to the use forms.


The formulations are produced, for example, by mixing the components with one another in the particular ratios desired. If the agrochemical substance is a solid substance, it is generally used either in finely ground form or in the form of a solution or suspension in an organic solvent or water. If the agrochemical substance is liquid, there is frequently no need to use an organic solvent. It is also possible to use a solid agrochemical substance in the form of a melt. The temperatures can be varied within a particular range in the course of performance of the process. In general, working temperatures are between 0° C. and 80° C., preferably between 10° C. and 60° C.


According to the formulation type, the production of the crop treatment compositions used in accordance with the invention is possible in various ways which are sufficiently well known to those skilled in the art. The procedure in the production may, for example, be to mix the alkoxylated vegetable oil derivatives with one or more agrochemical substances and optionally with auxiliaries. The sequence in which the components are mixed with one another is arbitrary. Useful equipment in the production is customary equipment which is used for production of agrochemical formulations.


In the use according to the invention, crop treatment compositions are preferably deployed in the form of spray liquors. This preferably involves production of a spray liquor by dilution of a concentrate formulation with a defined amount of water.


The invention further provides a method for reducing drift in the application of crop treatment compositions, wherein a preferably aqueous spray liquor is sprayed onto the plants to be treated or the site thereof, the spray liquor contains one or more alkoxylated vegetable oil derivatives and the amount of the one or more alkoxylated vegetable oil derivatives in the spray liquor is preferably from 0.001% to 5% by weight, more preferably from 0.005% to 3% by weight, especially preferably from 0.01% to 1% by weight and exceptionally preferably from 0.03% to 0.5% by weight, based in each case on the total weight of the spray liquor. The spray liquor used in the method of the invention further preferably contains one or more agrochemical substances.


The invention further provides compositions for reducing drift in the application of crop treatment compositions containing one or more of the alkoxylated vegetable oil derivatives described above and preferably spray liquors containing one or more of the alkoxylated vegetable oil derivatives described above, wherein the amount of the one or more alkoxylated vegetable oil derivatives in the spray liquor is preferably from 0.001% to 5% by weight, more preferably from 0.005% to 3% by weight, especially preferably from 0.01% to 1% by weight and exceptionally preferably from 0.03% to 0.5% by weight, based in each case on the total weight of the spray liquor. The compositions of the invention and preferably the spray liquors of the invention preferably further contain one or more agrochemical substances.

Preparation Examples
A) Preparation of Alkoxylated Vegetable Oil Derivatives Based on Castor Oil, Ethylene Oxide and Oleic Acid
A1) Preparation Example A1
Stage 1—Ethoxylation of Castor Oil

A 3 L stirred autoclave is initially charged with 915 g (1 mol) of castor oil, which are mixed homogeneously with 3.59 g (0.0256 mol) of potassium hydroxide solution (40% by weight in water) while purging with nitrogen. After evacuation to a pressure of 25-30 mbar, water is drawn off at 100° C. for 2 h and then the autoclave is purged repeatedly with nitrogen. Within 5 h, 880 g (20 mol) of ethylene oxide are then injected at a reaction temperature of 155° C. up to a maximum pressure of 2 bar. The exothermicity which occurs is compensated for by water cooling. After ethoxylation has ended, the internal pressure is increased to 4.0 bar with nitrogen and reaction is continued at 160° C. for 1 h. After cooling to 100° C., reduced pressure is applied for 1 h and any remaining by-products are removed. The intermediate is transferred after venting with nitrogen.


Stage 2—Esterification of the Castor Oil Ethoxylate with Oleic Acid


A 3 L four-neck flask is initially charged with 1795 g (0.95 mol) of castor oil ethoxylate (intermediate from stage 1), 401.2 g (1.425 mol) of oleic acid (Edenor Ti 05) and 5.5 g of esterification catalyst under a nitrogen atmosphere. The reaction mixture is then heated to 160° C. while stirring and stirred at this temperature for 2 h. Subsequently, the esterification reaction is continued at 180° C. for 4 h, and aqueous condensate is distilled off (top temperature: 70-103° C.) in order to obtain the product.


A2) Preparation Example A2
Stage 1—Ethoxylation of Castor Oil

A 3 L stirred autoclave is initially charged with 915 g (1 mol) of castor oil, which are mixed homogeneously with 3.59 g (0.0256 mol) of potassium hydroxide solution (40% by weight in water) while purging with nitrogen. After evacuation to a pressure of 25-30 mbar, water is drawn off at 100° C. for 2 h and then the autoclave is purged repeatedly with nitrogen. Within 5 h, 880 g (20 mol) of ethylene oxide are then injected at a reaction temperature of 155° C. up to a maximum pressure of 2 bar. The exothermicity which occurs is compensated for by water cooling. After ethoxylation has ended, the internal pressure is increased to 4.0 bar with nitrogen and reaction is continued at 160° C. for 1 h. After cooling to 100° C., reduced pressure is applied for 1 h and any remaining by-products are removed. The intermediate is transferred after venting with nitrogen.


Stage 2—Esterification of the Castor Oil Ethoxylate with Oleic Acid


A 1 L four-neck flask is initially charged with 372.8 g (0.20 mol) of castor oil ethoxylate (intermediate from stage 1), 71.7 g (0.25 mol) of oleic acid (Edenor Ti 05) and 1.11 g of esterification catalyst under a nitrogen atmosphere. The reaction mixture is then heated to 160° C. while stirring and stirred at this temperature for 2 h. Subsequently, the esterification reaction is continued at 180° C. for 2 h, and aqueous condensate is distilled off (top temperature: 70-103° C.) in order to obtain the product.

C) Use Examples
Measurement of Droplet Size Distribution

A Malvern Spraytec “real-time spray sizing system” was used to determine the droplet size distribution. For this purpose, the system (STP5321, Malvern Instruments GmbH, Heidelberg, Germany) was installed in a specially constructed spray cabin, with the option of being able to choose spray applications customary in practice with freely adjustable pressure for various hydraulic nozzles and freely adjustable distances (nozzle-target surface). The spray cabin can be darkened and all disruptive parameters can be switched off. For the measurements, the standard flat jet nozzle XR11002 (Teejet) with a high proportion of fine droplets (<105 μm) in the droplet spectrum and the injector nozzles ID12002 (Lechler) and ID(3)12002 (Lechler) having coarser droplet sizes were used. The pressure set was varied, and mean pressure was kept constant at 3 bar for the measurements reported hereinafter. The temperature and relative air humidity varied between 21.5° C. and 29° C. and between 33% and 56% respectively. In each test series, tap water was always measured as internal standard, and a spray liquor comprising the anti-drift adjuvant Synergen® OS as commercially available standard.


The Spraytec measurement was made at the setting of 1 kHz, since measurements at 2.5 kHz or higher, and also other influencing parameters such as additional suction, were found to be negligible. The measurement in the spray cone was kept constant at a position with distances of exactly 29.3 cm from the nozzle and 0.4 cm from the perpendicular below the nozzle. The measurements were made within 5 seconds, and the mean of 6 repetitions is reported as the proportion by volume of the droplets having diameters <90 μm (“Vol 90”), <105 μm (“Vol 105”) and <150 μm (“Vol 150”) (percentage standard error 0.5%-2.5%). As a further measurement parameter, the proportion by volume of the droplets having diameter <210 μm (“Vol 210”) was determined and expressed in relation to the proportion by volume of droplets having diameter <105 μm (“Vol 210/Vol 105”). In addition, the percentage reduction in the proportion by volume of droplets having diameter <105 μm in the case of use of spray liquors containing test substances was calculated in comparison to the use of tap water as internal standard (“Red 105”).
