The invention provides agrochemical aqueous suspension concentrate compositions that include fungicidal active ingredients suspended in water.
There is an ongoing need to develop effective pesticidal formulations, such as herbicidal, fungicidal, insecticidal, herbicidal, and nematicidal formulations, which exhibit desired characteristics, including having improved storage stability and shelf life.
Storage stability of agrochemical compositions can be adversely affected by numerous chemical and physical phenomena that provoke crystal growth e.g. known as Ostwald ripening.
Crystal growth of compounds, including agriculturally active compounds in agrochemical, such as pesticidal, compositions can result in undesirable properties. For example, a lack of efficacy of the pesticide, a need for increased dosage of the pesticide, non-optimal concentrations of the active in the formulation, decreased shelf-life of the formulation, and/or blockages in filters and nozzles used for application when the formulation is applied.
Crystal growth can occur by either of two mechanisms: (1) slow diffusion, and/or (2) slow attachment. The rate of crystal/particle growth is determined by the slower process.
Additionally, Ostwald ripening can be accelerated by temperature cycling.
There is a need to provide formulations of agriculturally active ingredients suspended in water that do not undergo Ostwald ripening or have reduced or slower occurrence of this phenomenon. There is also an ongoing need to increase shelf life of agricultural formulations. Further, there is always a need to increase bioavailability of the active ingredient in formulations, e.g. by increased penetration.
WO 2017/121695 describes the combination of herbicides with carriers to prevent agglomeration and improve redispersibility. U.S. Prov. 62/676,518 describes the use of Fluopyram and Isoflucypram in combination with hydroxypropylmethylcelluose ether (HPMC) in aqueous suspension concentrates.
WO 2015/124330 describes the use of Hydroxypropylmethylcellulose ether (HPMC) in combination with xanthan gum or other polysaccharides to provide storage stable aqueous fungicidal suspension concentrates.
However, none of these documents describes the combination of an azol type fungicide such as Difenoconazole with a succinate dehydrogenase inhibitor (“SDHT”) inhibitor such as Fluopyram or Isoflucypram in combination with a penetration enhancer. Furthermore, the mixture of such fungicides decreases the melting point of the corresponding active ingredients.
In particular, the mixtures of Difenoconazole and Fluopyram as well as Difenoconazole and Isoflucypram have a melting point of 65° C. only, which makes it very challenging to have crystal growth stable aqueous suspension concentrates as the tendency of crystal growth increases with reduced melting points of the active ingredients and their respective mixtures. The melting point was measured with a Mettler DTA (open, nitrogen purged on aluminium, 160 μL high) with a heating cycle of 3 K/min, from 30 to 450° C. at a nitrogen flow of 80 mL/min. The weight ratio was 1:1 for Difenoconazole:Isoflucypram and 1:2 for Difenoconazole:Fluopyram.
Another object of the present invention was also to include a penetration enhancer into the formulation. While these enhancers provide faster uptake of the active ingredients at higher concentrations without or with minimum loss of the active ingredient from the plant surface through physical wash off or bounce effects, however, these penetration enhancers not only swell the wax layers of the plant leaf, but also they do solubilize the active ingredients in the formulation so that the crystal growth behavior is further increased as solubilization of the active ingredient takes place.
A further object of the present invention was to provide a formulation in which crystal growth of DMIs as well as SDHIs in mixture formulations is prevented or significantly reduced.
The DMI (Demethylation Inhibitors) or Sterol Biosynthesis Inhibiting (SBI's) fungicides belong to FRAC code 3 which include the triazoles and imidazoles. DMI's work by inhibiting the biosynthesis of ergosterol which is a major component of the plasma membrane of certain fungi and needed for fungal growth. Resistance by fungi to the DMI fungicides has been characterized and is generally known to be controlled by the accumulation of several independent mutations, or what is known as ‘continuous selection’ or ‘shifting’, in the fungus.
Therefore, in a preferred embodiment DMI and SDHI (succinate dehydrogenase inhibitor) in combination as aqueous suspension concentrates are used. None of these above discussed documents describe the use of DMI and SDHI aqueous formulations that reduce crystal growth with low melting active ingredient combinations, in particular not without using hydroxypropylmethyl cellulose, while also preferably using penetration enhancers in the formulation.
In one embodiment the penetration enhancer is mandatory.
In one embodiment of the instant invention, agrochemical compositions of the present invention comprise at least one DMI and at least one succinate dehydrogenase inhibitor (“SDHI”/FRAC Class C2) as an active ingredient. Succinate dehydrogenase (“SDH”) is an enzyme complex found in the inner mitochondrial membrane of eukaryotes, as well as in many bacterial cells. SDH participates in both the citric acid cycle and the electron transport chain. In the citric acid cycle, SDH catalyzes oxidation of succinate to fumarate by coupling it with reduction of ubiquinone to ubiquinol. This catalysis occurs in the inner mitochondrial membrane.
In pesticidal and other agrochemical compositions such as suspensions, crystal growth of the active component can result in a thicker, more viscous composition. In Fluopyram suspension concentrate formulations, for example, long, needle-like crystals have been observed, resulting in solidification of the suspension concentrate formulations during shelf storage concentrations. Moreover, the needles or sediments tend to clog nozzles and pipes, which presents a problem during application.
In Difenoconazole formulations and also other DMI based fungicides, rather flat crystals will be found that grow over time. Furthermore, these growing crystals tend to agglomerate with the grown needle like crystals of the SDHI. Thus it is a challenge to find non agglomerating recipes.
The present invention solves the above mentioned problems.
In particular, in one embodiment of the instant invention the combination of low melting DMI and SDHI suspended in water can be stabilized with regard to crystal growth, wherein in one embodiment said stabilization is achieved without using hydroxypropylmethyl cellulose (HPMC) as crystal growth inhibitor (also crystal growth inhibiting carrier).

As crystal inhibitor carrier c3) any known cellulose ether can be used as a crystal growth inhibitor of the present invention. Cellulose ethers are generally known compounds that are commercially available, for example, as Methocel® from Dow Chemical Company, or as Culminal® from Hercules. They may be prepared by etherification of the polysaccharide cellulose. The manufacturing process may be carried out in either one of several steps. The reactions usually taking place are alkalization and alkylation. These reactions can be carried out in the presence or absence of solvents. Pure cellulose has large crystalline regions due to hydrogen-bonded hydroxyl groups and is thus insoluble in water and in most organic solvents. In the first step of cellulose ether manufacturing, cellulose may be activated with sodium hydroxide to become alkali cellulose. In some processes, alkali cellulose is degraded oxidatively much more rapidly than cellulose. Controlled reduction of the degree of polymerization allows for adjustment of the solution viscosities of the final products. By the selection of the substituent, the type of cellulose ether is determined. Mixed ethers can be produced with a mixture of reactants or by stepwise addition of the substituents. This reaction step may be carried out under pressure and at increased temperature. Alkylation may be carried out with alkyl halides. With epoxides, the process is called alkoxylation. As with all polymer reactions, this reaction may not occur uniformly along the polymer chain.
The cellulose ether can be methylhydroxyethyl cellulose or hydroxypropyl methylcellulose. In an aspect, the cellulose ether is hydroxypropyl methylcellulose. The cellulose ether may have solubility in water at 20° C. of at least 3 g/l, preferably of at least 10 g/l, and in particular of at least 20 g/l. The molecular weight of cellulose ether is usually determined by kinematic or dynamic viscosity. Lower viscosities mean typically lower molecular weight of the cellulose ether.

In another embodiment, the cellulose ether is Methocel E15 Premium from Dow Chemical Company.

Methods described herein can be used in the treatment of genetically modified organisms (GMOs), e.g., plants or seeds. Genetically modified plants (or transgenic plants) are plants of which a heterologous gene has been stably integrated into genome. The expression “heterologous gene” essentially means a gene which is provided or assembled outside the plant and when introduced in the nuclear, chloroplastic or mitochondrial genome gives the transformed plant new or improved agronomic or other properties by expressing a protein or polypeptide of interest or by downregulating or silencing other gene(s) which are present in the plant (using for example, antisense technology, cosuppression technology or RNA interference—RNAi—technology). A heterologous gene that is located in the genome is also called a transgene. A transgene that is defined by its particular location in the plant genome is called a transformation or transgenic event.
In an aspect, plants can be obtained by traditional breeding and optimization methods or by biotechnological and recombinant methods, or combinations of these methods, including the transgenic plants and including the plant varieties which are capable or not capable of being protected by Plant Breeders' Rights.
In another aspect, plant species and plant varieties which are found in the wild or which are obtained by traditional biological breeding methods, such as hybridization or protoplast fusion, and parts of these species and varieties are treated. In another embodiment, transgenic plants and plant varieties which were obtained by recombinant methods, if appropriate in combination with traditional methods (genetically modified organisms) and their parts are treated.
“Plant parts” should be understood as meaning all above ground and subsoil parts and organs of plants, such as shoot, leaf, flower, root, leaves, needles, stalks, stems, fruiting bodies, fruits and seeds, tubers and rhizomes. Plant parts also include harvested crops, and also vegetative and generative propagation material, for example cuttings, tubers, rhizomes, slips and seeds.
Seeds, plant parts, leaves, and plants may be treated with the described compositions by applying the compounds or compositions directly to the seed, plant part, leaf, or plant. In another aspect, the seed, plant part, leaf, or plant may be treated indirectly, for example by treating the environment or habitat in which the seed, plant part, leaf, or plant is exposed to. Conventional treatment methods may be used to treat the environment or habitat including dipping, spraying, fumigating, chemigating, fogging, scattering, brushing on, shanking or injecting.
“Habitat” denotes where a plant or crop is growing or where a plant or crop will be grown. The composition can be used to treat the plant, crop, or habitat thereof.
According to the invention, the treatment of the plants and seeds with a composition described herein can be carried out directly by the customary treatment methods, for example by immersion, spraying, vaporizing, fogging, injecting, dripping, drenching, broadcasting or painting, and seed treatment.
A composition described herein can take any of a variety of dosage forms including, without limitation, suspension concentrates, aerosols, capsule suspensions, cold-fogging concentrates, warm-fogging concentrates, encapsulated granules, fine granules, flowable concentrates for the treatment of seed, ready-to-use solutions, dustable powders, emulsifiable concentrates, oil-in-water emulsions, water-in-oil emulsions, macrogranules, microgranules, oil-dispersible powders, oil-miscible flowable concentrates, oil-miscible liquids, foams, pastes, pesticide-coated seed, suspoemulsion concentrates, soluble concentrates, wettable powders, soluble powders, dusts and granules, water-soluble granules or tablets, water-soluble powders for the treatment of seed, wettable powders, natural products and synthetic substances impregnated with a compound or composition described herein, a net impregnated with a compound or composition described herein, and also microencapsulations in polymeric substances and in coating materials for seed, and also ULV cold-fogging and warm-fogging formulations.
These compositions include not only compositions which are ready to be applied to the plant or seed to be treated by means of a suitable device, such as a spraying or dusting device or drones, but also concentrated commercial compositions which must be diluted before they are applied to the crop.
The pesticidal compositions of the present invention can be used to curatively or preventively control phytopathogenic fungi on crops, but also to curatively or preventively control nematodes and/or insects.
The composition according to the present invention is well tolerated by plants, have favorable homeotherm toxicity and are environmentally friendly; it is suitable for protecting plants and plant organs, for increasing harvest yields, for improving the quality of the harvested material and for controlling animal pests, in particular insects, arachnids and nematodes encountered in agriculture, in forests, in gardens and leisure facilities, in the protection of stored products and materials and in the hygiene sector. It is preferably used as crop protection agents. It is active against normally sensitive and resistant species and against all or some stages of development. Among the animal pests that can also be controlled by the method according to the present invention, mention may be made of:
The plant-parasitic nematodes such as species of the genera Aphelenchoides spp., Bursaphelenchus spp., Ditylenchus spp., Globodera spp., Heterodera spp., Longidorus spp., Meloidogyne spp., Pratylenchus spp., Radopholus spp., Trichodorus spp., Tylenchulus spp, Xiphinema spp., Helicotylenchus spp., Tylenchorhynchus spp., Scutellonema spp., Paratrichodorus spp., Meloinema spp., Paraphelenchus spp., Aglenchus spp., Belonolaimus spp., Nacobbus spp, Rotylenchulus spp., Rotylenchus spp., Neotylenchus spp., Paraphelenchus spp., Dolichodorus spp., Hoplolaimus spp., Punctodera spp., Criconemella spp., Quinisulcius spp., Hemicycliophora spp., Anguina spp., Subanguina spp., Hemicriconemoides spp., Psilenchus spp., Pseudohalenchus spp., Criconemoides spp., Cacopaurus spp.

The following examples serve to illustrate certain aspects of the disclosure and are not intended to limit the disclosure.
All tests were performed after customary in crop protection CIPAC methods (CIPAC=Collaborative International Pesticides Analytical Council; www.cipac.org). The long-term storage was carried out 40° C. Storage time after CIPAC MT 46.3. Storage time and temperature as indicated in the tables. The particle size was measured using CIPAC MT 187 testing method for agrochemicals. D90 particle size, crystal growth out which increases.
General preparation of the suspension concentrate:
The active ingredients and formulation inerts were added without any special order. The mixture was pregrinded using a rotar stator until a particle size of 80-150 μm was achieved. The mixture was further grinded using a bead mill until the final particle size of 2-10 μm was achieved. The thickener xanthan gum was added at the end to adjust the final viscosity. In a preferred embodiment the penetration enhancer is added after milling.
Used materials:
R3 is an example without the penetration enhancer f. The amounts of dispersant d) and e) was slightly modified to match the final viscosity. There was no particle size growth observed and no agglomerates were present during accelerated storage. However, in view of biological performance of this formulation a penetration enhancer f) is needed, since cuticle penetration is unsufficient as can be seen below (Table 3).
R14 was made based on the combination of a hydroxypropylmethylcellulose ether (Benecel K 200M) and xanthan gum as thickener as described by WO2015124330 for Fluoxypyroxad based fungicide formulations. However, the formulation was not stable, there were two phases and separation of the solids though the particle size growth was acceptable. R13 without the used a additional Benecel K 200M was even worse than R15.
R29 was using additionally Aerosil R 972 as crystal growth inhibiting carrier material. Though the particle size was slightly higher than R13 and R14, the liquid was flowable after mixing of the stored samples and could be further utilized. However, in comparison to R35, R 36 and R37, it is less preferred adding additional hydroxypropylmethylcellulose ether to the formulation.
R30 is using Aerosil 200 (hydrophilic silica) in comparison to R29. The crystal growth is also quite high, however, the formulation stays flowable after storage. However, same as R29 this formulation contains hydroxypropylmethylcellulose ether and is less preferred.
R35-R37 are preferred formulations as the crystal growth is very low and the formulation stays fluid without separation or sediment upon accelerated storage.
Evaluation of Bioavailability/Penetration Enhancement
A spray mixture (0.5 g of active ingredient/L) is added to each of three apple cuticles. The amount of active substance in the cuticle is measured; after drying after 0, 24 and 72 h determined by HPLC.
The penetration enhancer shows more than 4 times more penetration of the active ingredient.
