1. Field of the Invention
The present invention relates to novel water-dispersible agrochemical formulations such as, for example, water-based suspension concentrates and water-dispersible granules of agrochemically active compounds, to a process for preparing these formulations and to their use for applying the active compounds comprised therein.
2. Description of Related Art
To unfold their biological action, systemic agrochemically active compounds, in particular systemic insecticides and fungicides, require a formulation which allows the active compounds to be taken up by the plant/the target organisms. Accordingly, systemic agrochemically active compounds are usually formulated as an emulsion concentrate (EC), as a soluble liquid (SL) and/or as an oil-based suspension concentrate (OD). In an EC formulation and in an SL formulation, the active compound is present in dissolved form; in an OD formulation, the active compound is present as a solid. In general, a suspension concentrate (SC) or water-dispersible granules (WG) are technically also feasible. Hereinbelow, only suspension concentrates are described; however, this is meant to include other types of formulation where the active compound is present in a water-dispersible form. However, to achieve a satisfactory biological action when using SC formulations, it is necessary for the active compound in the SC to be combined with an additive. In this context, an additive is a component which improves the biological action of the active compound, without the component for its part having a biological action. In particular, an additive permits/facilitates the uptake of the active compound into the leaf (penetrant). A penetrant may be incorporated into the formulation of the agrochemically active compound (in-can formulation) or be added after dilution of the concentrated formulation of the spray liquor (tank-mix). To avoid dosage errors and to improve user safety during application of agrochemical products, it is advantageous to incorporate the penetrants into the formulation. This also avoids the unnecessary use of additional packaging material for the tank-mix products.
Some water-based suspension concentrates of agrochemically active compounds comprising penetrants are already known. Thus, WO 05/036963 describes formulations of this type which, in addition to certain fungicides, also comprise at least one penetrant from the group of the alkanolethoxylates. WO 99/060851 describes various alkanolethoxylates based on fatty alcohols.
A disadvantage of the formulations, mentioned above, with penetrants is the fact that, in particular in the case of application to leaves, fruits or other parts of plants in sensitive crop plants, such as pome fruit (for example Malus domestica, Pyrus communis), stone fruit (Prunus armeniaca, Prunus domestica, Prunus persica), citrus crops, vegetables, such as, for example, bell peppers (Capsicum annuum) and cantaloupes (Cucumis melo), and also ornamental plants, such as roses, the spray liquor residue left after application and drying of the spray liquid may cause damage to the plants.
Furthermore, Pest. Manag. Sci. 58:825-833 (2002) discloses triglyceride ethoxylates (Agnique® RSO series) which are recommended for use as tank-mix penetrants for systemic water-soluble agrochemically active compounds. As an advantage of these auxiliaries, the plant compatibility on weeds was mentioned. This is characterized by having no effect on photosynthesis, which is advantageous for the systemic action of phloem-mobile active compounds such as glyphosate. However, the spray liquor concentrations required for a satisfactory uptake of active compound were between 1 and 10 g/l, which is incompatible with an in-can formulation.
US 2002/01 55954 mentions triglyceride ethoxylates which reduce the surface tension of the spray liquor to less than 40 mN/m as additives. In this application, the triglyceride ethoxylates are described in an in-can formulation. However, because of their origin, the castor oil-based triglyceride ethoxylates described in this publication differ significantly, structurally, from the triglyceride ethoxylates according to the invention. Castor oil is a vegetable oil which has a hydroxy functionality in the aliphatic side chains, therefore requiring an additional ethoxylation in this position. This is in contrast to the triglyceride ethoxylates according to the invention which are ethoxylated only between the glyceride unit and the various aliphatic side chains.
It is an object of the present invention to develop stable, storable, water-based suspension concentrates comprising at least one penetrant, without adversely affecting plant compatibility.
It has been found that this object is achieved by water-dispersible agrochemical formulations comprising a penetrant from the class of the polyalkoxytriglycerides. Accordingly, the present invention provides water-dispersible agrochemical formulations, comprising
The compositions according to the invention are preferably liquid suspension concentrates comprising
Preference is also given to water-dispersible granules which can be prepared by customary methods, comprising
Furthermore, it has been found that water-based suspension concentrates according to the invention can be prepared by mixing together
Finally, it has been found that the suspension concentrates according to the invention are highly suitable for applying the agrochemically active compounds comprised therein to plants and/or their habitat.
The formation of plant damage is complex and can be traced back to the penetration of penetrants such as alkanolethoxylates in particular at the edge of the spray droplets on the plant. This may result in high local concentrations of additive and/or active compound, causing necrotic rings or circles to appear on the treated plant surface, the area of some of which will extend owing to the destruction of tissue. Surprisingly, it has now been found that the occurrence of necroses is associated with the presence of stomata or structures derived therefrom, such as, for example, lenticels. Furthermore, polyalkoxytriglycerides were found which facilitate the uptake of active compound but which, surprisingly and in contrast to other penetrants typically employed, do not lead to necroses. Thus, for example, the use of alkanolethoxylates—with or without active compound—on the underside of rose leaves at concentrations of 0.1-1 g/l results in strong ring necroses, whereas with polyalkoxytriglycerides—likewise with or without active compound—no necroses are observed. It is not known why necroses occur just with sensitive plants on the side of the leaf with stomata. Furthermore, it has been found that, at use concentrations of 0.1-1 g/l, these compatible polyalkoxytriglycerides are distinguished in that their spray liquors have surface tension values of more than 41 mN/m, in contrast to US 2002/0155954.
It is furthermore surprising that polyalkoxytriglycerides, such as, for example, rapeseed oil ethoxylate Crovol® CR70G (Croda) facilitates the uptake of very different substances (for example substances of differing lipophilicity, electrolytes and non-electrolytes), such as, for example, sulphonylureas, ketoenols, azol fungicides, etc. Here, in the case of the polyalkoxytriglycerides according to the invention, the uptake kinetics are distinguished in that, in contrast to known penetrants, penetration of the active compound takes place not preferably immediately after application, with a considerable decrease thereafter, but with very constant kinetics over a period of several days. This effect, too, affects plant compatibility positively since it is thus possible to avoid temporary high local concentrations of critically active compounds in the leaf tissue.
The incompatibility of herbicides is also crucially dependent on the rapid formation of high local concentrations in the treated organs of the crop plant. As a result, herbicides, such as, for example sulphonylureas, are less well tolerated in cereals when penetrants are used, which cause a rapid uptake of active compound after application. In contrast, a slow uptake of the herbicide is often tolerated well. Since the properties found of the polyalkoxytriglycerides, which for their part do not cause necroses and which facilitate the slow but long-lasting uptake of active compound from the spray coating also applies to herbicidally active compounds, there is a positive effect on the selectivity of herbicides compared to alkanolethoxylates or rapeseed oil methyl ester penetrants, for example.
Finally, it is extremely surprising that the suspension concentrates according to the invention have very good stability. The polyalkoxytriglycerides used, like the dispersants of a water-based suspension concentrate, have surfactant properties, which normally results in a competition with the dispersants. Especially at high storage temperature or after storage at changing temperature conditions, this results in a destabilization of the suspension concentrate.
Preferred embodiments of the subject of the invention are described below.
Suitable penetrants in the present context are polyalkoxytriglycerides. Polyalkoxytriglycerides can be prepared by alkoxylation of triglycerides. The alkoxylation of triglycerides gives substance mixtures in which one to three of the side chains are alkoxylated. In alkoxylations, a distinction may be made between ethoxylation, propoxylation, butoxylation or a mixture of these processes. For each of the side chains, the length of the unmodified side chains can vary from 9 to 24, preferably from 12 to 22, very preferably from 14 to 20, carbon atoms independently of the other side chains in the same molecule. These aliphatic side chains can be straight-chain or branched.
In a preferred embodiment of the present invention, the polyalkoxytriglycerides are obtained by ethoxylation of triglycerides.
In a particularly preferred embodiment of the present invention, the polyalkoxytriglycerides are obtained by ethoxylation of rapeseed oil, maize oil, palm kernel oil or almond oil.

When used, the compositions according to the invention can furthermore be present in their commercially available formulations and in the use forms, prepared from these formulations, as a mixture with synergistic agents. Synergistic agents are compounds which increase the action of the active compounds present in the compositions according to the invention, without it being necessary for the synergistic agent added to be active itself.
When used, the compositions according to the invention can furthermore be present in their commercially available formulations and in the use forms, prepared from these formulations, as mixtures with inhibitors which reduce degradation of the agrochemically active compound present after use in the environment of the plant, on the surface of parts of plants or in plant tissues.
The active compound content of the use forms prepared from the commercially available formulations can vary within wide limits. The active compound concentration of the use forms can be from 0.00000001 to 95% by weight of active compound, preferably between 0.00001 and 1% by weight.
The compounds are employed in a customary manner appropriate for the use forms.
All plants and plant parts can be treated in accordance with the invention. Plants are to be understood as meaning in the present context all plants and plant populations such as desired and undesired wild plants or crop plants (including naturally occurring crop plants). Crop plants can be plants which can be obtained by conventional breeding and optimization methods or by biotechnological and genetic engineering methods or by combinations of these methods, including the transgenic plants and including the plant cultivars which can or cannot be protected by plant breeders' rights. Plant parts are to be understood as meaning all parts and organs of plants above and below the ground, such as shoot, leaf, flower and root, examples which may be mentioned being leaves, needles, stalks, stems, flowers, fruit bodies, fruits and seeds, as well as roots, tubers and rhizomes. The plant parts also include harvested material, and vegetative and generative propagation material, for example cuttings, tubers, rhizomes, offshoots and seeds.
Treatment according to the invention of the plants and plant parts with the compositions is carried out directly or by action on their environment, habitat or storage space using customary treatment methods, for example by dipping, spraying, evaporating, atomizing, broadcasting, spreading-on, injecting and, in the case of propagation material, in particular in the case of seeds, furthermore by coating with one or more layers.
As already mentioned above, it is possible to treat all plants and their parts according to the invention. In a preferred embodiment, wild plant species and plant cultivars, or those obtained by conventional biological breeding methods, such as crossing or protoplast fusion, and parts thereof, are treated. In a further preferred embodiment, transgenic plants and plant cultivars obtained by genetic engineering methods, if appropriate in combination with conventional methods (Genetically Modified Organisms), and parts thereof are treated. The terms “parts”, “parts of plants” and “plant parts” have been explained above.
Particularly preferably, plants of the plant cultivars which are in each case commercially available or in use are treated according to the invention. Plant cultivars are to be understood as meaning plants having novel properties (“traits”) which have been obtained by conventional breeding, by mutagenesis or by recombinant DNA techniques. These can be cultivars, bio- or genotypes.
Depending on the plant species or plant cultivars, their location and growth conditions (soils, climate, vegetation period, diet), the treatment according to the invention may also result in superadditive (“synergistic”) effects. Thus, for example, reduced application rates and/or a widening of the activity spectrum and/or an increase in the activity of the substances and compositions which can be used according to the invention, better plant growth, increased tolerance to high or low temperatures, increased tolerance to drought or to water or soil salt content, increased flowering performance, easier harvesting, accelerated maturation, higher harvest yields, higher quality and/or a higher nutritional value of the harvested products, better storage stability and/or processability of the harvested products are possible, which exceed the effects which were actually to be expected.
The transgenic plants or plant cultivars (obtained by genetic engineering) which are preferably to be treated according to the invention include all plants which, by virtue of the genetic modification, received genetic material which imparted particular advantageous, useful traits to these plants. Examples of such traits are better plant growth, increased tolerance to high or low temperatures, increased tolerance to drought or to water or soil salt content, increased flowering performance, easier harvesting, accelerated maturation, higher harvest yields, higher quality and/or a higher nutritional value of the harvested products, better storage stability and/or processability of the harvested products. Further and particularly emphasized examples of such traits are a better defence of the plants against animal and microbial pests, such as against insects, mites, phytopathogenic fungi, bacteria and/or viruses, and also increased tolerance of the plants to certain herbicidally active compounds. Examples of transgenic plants which may be mentioned are the important crop plants, such as cereals (wheat, rice), maize, soya beans, potatoes, sugar beet, tomatoes, peas and other vegetable varieties, cotton, tobacco, oilseed rape and also fruit plants (with the fruits apples, pears, citrus fruits and grapes), and particular emphasis is given to maize, soya beans, potatoes, cotton, tobacco and oilseed rape. Traits that are emphasized are in particular the increased defence of the plants against insects, arachnids, nematodes and slugs and snails by virtue of toxins formed in the plants, in particular those formed in the plants by the genetic material from Bacillus thuringiensis (for example by the genes CryIA(a), CryIA(b), CryIA(c), CryIIA, CryIIIA, CryIIIB2, Cry9c, Cry2Ab, Cry3Bb and CryIF and also combinations thereof) (referred to hereinbelow as “Bt plants”). Traits that are also particularly emphasized are the increased defence of plants against fungi, bacteria and viruses by systemic acquired resistance (SAR), systemin, phytoalexins, elicitors and resistance genes and correspondingly expressed proteins and toxins. Traits that are furthermore particularly emphasized are the increased tolerance of the plants to certain herbicidally active compounds, for example imidazolinones, sulphonylureas, glyphosate or phosphinotricin (for example the “PAT” gene). The genes which impart the desired traits in question can also be present in combinations with one another in the transgenic plants. Examples of “Bt plants” which may be mentioned are maize varieties, cotton varieties, soya bean varieties and potato varieties which are sold under the trade names YIELD GARD® (for example maize, cotton, soya beans), KnockOut® (for example maize), StarLink® (for example maize), Bollgard® (cotton), Nucotn® (cotton) and NewLeaf® (potato). Examples of herbicide-tolerant plants which may be mentioned are maize varieties, cotton varieties and soya bean varieties which are sold under the trade names Roundup Ready® (tolerance to glyphosate, for example maize, cotton, soya bean). Liberty Link® (tolerance to phosphinotricin, for example oilseed rape), IMI® (tolerance to imidazolinones) and STS® (tolerance to sulphonylureas, for example maize). Herbicide-resistant plants (plants bred in a conventional manner for herbicide tolerance) which may be mentioned include the varieties sold under the name Clearfield® (for example maize). Of course, these statements also apply to plant cultivars having these genetic traits or genetic traits still to be developed, which plant cultivars will be developed and/or marketed in the future.
The plants listed can be treated according to the invention in a particularly advantageous manner with the compositions according to the invention. The preferred ranges stated above for the compositions also apply to the treatment of these plants. Particular emphasis is given to the treatment of plants with the compositions specifically mentioned in the present text.

The compositions according to the invention comprising at least one herbicidally active compound (=herbicidal compositions) have excellent herbicidal activity against a broad spectrum of economically important mono- and dicotyledonous harmful plants. In this context, it is immaterial whether the substances are applied pre-sowing, pre-emergence or post-emergence.
By way of example, specific mention may be made of some representatives of the mono- and dicotyledonous weed flora which can be controlled by the compounds according to the invention; however, this list is not to be understood as meaning a limitation to certain species.
Among the monocotyledonous grass species, the compounds act efficiently, for example, both against self-sown cereals, such as wheat, barley, rye and triticale, and, for example, against Apera spica venti, Avena spp., Alopecurus spp., Brachiaria spp., Digitaria spp., Lolium spp., Echinochloa spp., Panicurn spp., Phalaris spp., Poa spp., Setaria spp. and also Bromus spp., such as Bromus catharticus, Bromus secalinus, Bromus erectus, Bromus tectorum and Bromus japonicus, and Cyperus species from the annual group and, from among the perennial species, Agropyron, Cynodon, Imperata and Sorghum, and also perennial Cyperus species.
In the case of the dicotyledonous weed species, the spectrum of action extends to species such as, for example, Abutilon spp., Amaranthus spp., Chenopodium spp., Chrysanthemum spp., Galium spp., Ipomoea spp., Kochia spp., Lamium spp., Matricaria spp., Pharbitis spp., Polygonum spp., Sida spp., Sinapis spp., Solanum spp., Stellaria spp., Veronica spp. and Viola spp., Xanthium spp., Papaver rhoeas spp., Centaurea spp. among the annual species, and also Convolvulus, Cirsium, Rumex and Artemisia spp. among the perennial weeds.
If the herbicidal compositions according to the invention are applied to the soil surface prior to germination, then the weed seedlings are either prevented completely from emerging, or the weeds grow until they have reached the cotyledon stage but then their growth stops, and, eventually, after three to four weeks have elapsed, they die completely.
If the active compounds are applied post-emergence to the green parts of the plants, growth also stops drastically a very short time after the treatment and the weed plants remain at the developmental stage of the point in time of application, or they die completely after a certain time, so that in this manner competition by the weeds, which is harmful to the crop plants, is eliminated at a very early point in time and in a sustained manner.
The herbicidal compositions according to the invention are distinguished by a rapid and long-lasting herbicidal action. The shower resistance of the active compounds in the combinations according to the invention is generally favourable. By using the active compound combination according to the invention, it is possible to reduce the required application rate of the active compounds considerably.
The herbicidal compositions according to the invention have excellent herbicidal activity against a broad spectrum of economically important monocotyledonous and dicotyledonous harmful plants including species resistant against herbicidally active compounds such as glyphosate, glufosinate, atrazine or imidazolinone herbicides.
Although the herbicidal compositions according to the invention have an excellent herbicidal activity against monocotyledonous and dicotyledonous harmful plants, the crop plants are not damaged at all, or only to a negligible extent.
In addition, the compositions according to the invention in some cases have outstanding growth-regulating properties in crop plants. They engage in the plant metabolism in a regulating manner and can thus be employed for the targeted control of plant constituents and for facilitating harvesting, for example by provoking desiccation and stunted growth. Furthermore, they are also suitable for generally regulating and inhibiting undesirable vegetative growth, without destroying the plants in the process. Inhibition of vegetative growth plays an important role in many monocotyledonous and dicotyledonous crops because lodging can be reduced hereby, or prevented completely.
By virtue of their herbicidal and plant growth-regulatory properties, the compositions according to the invention can be employed for controlling harmful plants in crop plants which are genetically modified or have been obtained by mutation/selection. These crop plants generally have particularly advantageous properties, for example resistance to herbicidal compositions or plant diseases or causative organisms of plant diseases, such as certain insects or microorganisms such as fungi, bacteria or viruses. Other particular properties relate, for example, to the quantity, quality, storage-stability, composition and specific ingredients of the harvested product. Thus, for example, transgenic plants having an increased starch content or a modified quality of the starch or those having a different fatty acid composition of the harvested product are known.
Conventional ways of preparing novel plants which have modified properties compared to known plants comprise, for example, traditional breeding methods and the generation of mutants (see, for example, U.S. Pat. No. 5,162,602; U.S. Pat. No. 4,761,373; U.S. Pat. No. 4,443,971). Alternatively, novel plants having modified properties can be generated with the aid of genetic engineering methods (see, for example, EP-A-0 221 044, EP-A-0 131 624). For example, there have been described several cases of
Numerous molecular biological techniques which allow the preparation of novel transgenic plants having modified properties are known in principle; see, for example, Sambrook et al., 1989, Molecular Cloning, A Laboratory Manual, 2nd Ed., Cold Spring Harbor Laboratory Press, Cold Spring Harbor, NY; or Winnacker “Gene und Klone” [Genes and Clones], VCH Weinheim, 2nd Edition 1996, or Christou, “Trends in Plant Science” 1 (1996) 423-431).
In order to carry out such genetic engineering manipulations, it is possible to introduce nucleic acid molecules into plasmids which allow a mutagenesis or a change in the sequence to occur by recombination of DNA sequences. Using the abovementioned standard processes it is possible, for example, to exchange bases, to remove partial sequences or to add natural or synthetic sequences. To link the DNA fragments with each other, it is possible to attach adaptors or linkers to the fragments.
Plant cells having a reduced activity of a gene product can be prepared, for example, by expressing at least one appropriate antisense-RNA, a sense-RNA to achieve a cosuppression effect, or by expressing at least one appropriately constructed ribozyme which specifically cleaves transcripts of the abovementioned gene product.
To this end it is possible to employ both DNA molecules which comprise the entire coding sequence of a gene product including any flanking sequences that may be present, and DNA molecules which comprise only parts of the coding sequence, it being necessary for these parts to be long enough to cause an antisense effect in the cells. It is also possible to use DNA sequences which have a high degree of homology to the coding sequences of a gene product but which are not entirely identical.
When expressing nucleic acid molecules in plants, the synthesized protein can be localized in any desired compartment of the plant cell. However, to achieve localization in a certain compartment, it is possible, for example, to link the coding region with DNA sequences which ensure localization in a certain compartment. Such sequences are known to the person skilled in the art (see, for example, Braun et al., EMBO J. 11 (1992), 3219-3227; Wolter et al., Proc. Natl. Acad. Sci. USA 85 (1988), 846-850; Sonnewald et al., Plant J. 1 (1991), 95-106).
The transgenic plant cells can be regenerated to whole plants using known techniques. The transgenic plants can in principle be plants of any desired plant species, i.e. both monocotyledonous and dicotyledonous plants. In this manner, it is possible to obtain transgenic plants which have modified properties by overexpression, suppression or inhibition of homologous (=natural) genes or gene sequences or by expression of heterologous (=foreign) genes or gene sequences.
Furthermore, the present invention also provides a method for controlling unwanted vegetation (for example harmful plants), preferably in crop plants such as cereals (for example wheat, barley, rye, oats, crossbreeds thereof, such as triticale, rice, corn, millet), sugar beet, sugar cane, oilseed rape, cotton and soya bean, particularly preferably in monocotyledonous crops such as cereals, for example wheat, barley, rye, oats, crossbreeds thereof, such as triticale, rice, corn and millet, or in dicotyledonous crops, which method comprises applying one or more herbicides of type (A) and one or more herbicides of type (B) jointly or separately, for example by the pre-emergence method, the post-emergence method or the pre- and post-emergence method, to the plants, for example harmful plants, parts of plants, plant seed or the area on which the plants grow, for example the area under cultivation.
The crop plants may also be genetically modified or obtained by mutation/selection.
The herbicidal compositions according to the invention can also be employed non-selectively for controlling unwanted vegetation, for example in plantation crops, on roadsides, squares, industrial sites or railway tracks.
The preparation and use examples below illustrate the invention without limiting it in any way.
To prepare a suspension concentrate, initially all liquid components are mixed with one another. In the next step, the solids are added and the mixture is stirred until a homogeneous suspension is formed. The homogeneous suspension is subjected initially to coarse grinding and then to fine grinding, resulting in a suspension in which 90% of the solids particles have a particle size below 10 μm. Subsequently, Kelzan® S and water are added at room temperature with stirring. This gives a homogeneous suspension concentrate.
Storage Stability of the Formulations According to the Invention
To examine the storage stability, 100 ml of formulation were stored under changing temperature conditions (TW) and at 54° C. for eight weeks. The changing temperature conditions are 48 hours at 30° C., reduction of the temperature over 22.5 hours at 2° C./hour to −15° C., 75 hours at −15° C., increase of the temperature over 22.5 hours at 2° C./hour to 30° C. After storage, the sample is brought to room temperature, and dispersibility, particle size and viscosity are checked.
The dispersibility (DISP) is determined according to the CIPAC MT 180 method, the particle size (d90, Part) is measured on a Malvern Mastersizer 2000, and the dynamic viscosity (Visc) is measured at 20 s−1 using a RheoStress RS 150 from Haake.
Determination of the Static Surface Tension
Surface tens ion of the penetrants according to the invention at 0.5 g/l in tap water and at room temperature measured using a Krüss tensiometer K100 Wilhelmy plate method in accordance with ASTM D 1331-56.
Determination of the Plant Compatibility of Various Adjuvants
Plant compatibility of the penetrants (on their own) at 0.5 g/l in tap water on sensitive leaves of miniroses. Plants in a climatized cabinet at 20° C./60% atmospheric humidity during the day and 18° C./70% atmospheric humidity at night.
Depending on the penetrant, 4×10 μl drops were applied to the upper side of a leaf, in each case two on the two halves of the leaf as defined by the central axis. A number of leaves of the same plant were used. Moreover, as an internal standard for a typical reaction of the leaf, Genapol C-100 was applied to the front third of the leaf, resulting in a ring-shaped necrosis. Application and drying were carried out at a relative atmospheric humidity of 30-40% and a temperature of ˜21° C.
Evaluation was carried out visually using an evaluation template. Furthermore, photos were taken with a digital camera. To exclude the possibility that spray coatings are identified as damage, all application sites were stripped with cellulose acetate and an additional scoring was carried out after removal of the spray coating.
Determination of the Plant Compatibility of Various Spirotetramate/Adjuvant Combinations
Plant compatibility of spray liquors comprising the insecticide spirotetramate (0.2 g/l) with the penetrants at 0.5 g/l in tap water on bell pepper leaves (Capsicum annuum cv. Pusta Gold). Plants in a climatized cabinet at 20° C./60% atmospheric humidity during the day and 18° C./70% atmospheric humidity at night.
Depending on the penetrant, 2×10 μl drops were applied in each case once to both halves of the leaf as defined by the central axis. A plurality of penetrants were applied to one leaf (upper side) and a number of leaves of the same plant were used. Moreover, as an internal standard for a typical reaction of the leaf, Genapol C-100 was applied to the front third of the leaf, resulting in a ring-shaped necrosis. Application and drying were carried out at a relative atmospheric humidity of 30-40% and a temperature of ˜21° C.
Evaluation was carried out visually using an evaluation template. Furthermore, photos were taken with a digital camera. To exclude the possibility that spray coatings are identified as damage, all application sites were stripped with cellulose acetate and an additional scoring was carried out after removal of the spray coating.
Determination of the Plant Compatibility of Various Tebuconazole/Penetrant Combinations
Plant compatibility on soya bean leaves of tebuconazole formulated as WG with rapeseed oil methyl ester penetrant (Mero®) and Crovol® CR70G.
Depending on the penetrant, 2×10 μl drops were applied to the leaf, in each case to both halves of the leaf as defined by the central axis. A plurality of penetrants were applied to one leaf (upper side) and a number of leaves of the same plant were used. Application and drying were carried out at a relative atmospheric humidity of 30-40% and a temperature of ˜21° C.
Evaluation was carried out visually using an evaluation template. Furthermore, photos were taken with a digital camera. To exclude the possibility that spray coatings are identified as damage, all application sites were stripped with cellulose acetate and an additional scoring was carried out after removal of the spray coating.
Determination of the Cuticle Penetration of Various Spirotetramate/Penetrant Combinations
Penetration* of spirotetramate with penetrants according to the invention compared to the control without penetrant and the rapid-action uptake enhancer Genapol® X150. All penetrants employed at 0.5 g/l.
This test measured the penetration of active compounds through enzymatically isolated cuticles of apple leaves.
The leaves used were cut in the fully developed state from apple trees of the Golden Delicious variety. The cuticles were isolated as follows:
Thereafter only those cuticles from the top leaf sides that were free from stomata and hairs were used further. They were washed a number of times in alternation with water and with a buffer solution, pH 7. The clean cuticles obtained were, finally, applied to Teflon plaques and smoothed and dried with a gentle jet of air.
In the next step the cuticular membranes obtained in this way were placed in stainless steel diffusion cells (transport chambers) for the purpose of membrane transport investigations. For these investigations the cuticles were placed centrally using tweezers on the edges of the diffusion cells, which were coated with silicone grease, and sealed with a ring, which was likewise greased. The arrangement was chosen so that the morphological outer side of the cuticles was directed outwards, in other words to the air, while the original inner side was facing the interior of the diffusion cell.
The diffusion cells were filled with a 1% phospholipid suspension. Penetration was determined by applying in each case 10 μl of the spray liquor of the composition below, containing radiolabeled active compound in the stated concentrations, to the outer face of the cuticles. The spray liquor is prepared using local tap water of average hardness.
After the spray liquors had been applied, the water was evaporated and then the chambers were inverted and placed in thermostatted troughs, in which the temperature and air humidity over the cuticles was adjustable by means of a gentle air stream onto the cuticles with the spray coating (20° C., 60% rh). At regular intervals, an autosampler took aliquots which were subjected to measurement in a scintillation counter.
