The invention relates to storage-stable prothioconazole-containing formulations having a particularly low content of 2-(1-chlorocyclopropyl)-1-(2-chlorophenyl)-3-(1H-1,2,4-triazol-1-yl)propan-2-ol based on organic vinyl compounds, to a process for their preparation, to a method for controlling phytopathogenic fungi in crop protection and to their use as crop protection agents.
It is already known that prothioconazole can be used in standard formulations for control of fungi (WO-A 96/16 048). This active ingredient is 2-[2-(1-chlorocyclopropyl)-3-(2-chlorophenyl)-2-hydroxypropyl]-2,4-dihydro-3H-1,2,4-triazole-3-thione. Prothioconazole-containing formulations are generally liquid formulations and are supplied on the market, for example, in the form of emulsion concentrates.
It is known that the active ingredient prothioconazole can be degraded under particular conditions to give the compound 2-(1-chlorocyclopropyl)-1-(2-chlorophenyl)-3-(1H-1,2,4-triazol-1-yl)propan-2-ol (PSM-Zulassungsbericht [Crop Protection Agent Registration Report], Tilmor, 2010.08.30, serial no. 21, German Federal Office of Consumer Protection and Food Safety).
Therefore, prothioconazole (hereinbelow referred to as PTZ)-containing formulations, as early as in the course of production, may contain a certain amount of 2-(1-chlorocyclopropyl)-1-(2-chlorophenyl)-3-(1H-1,2,4-triazol-1-yl)propan-2-ol. In the case of storage under severe conditions, such as elevated temperatures, incidence of light and intensive oxygen contact, it is likewise possible for degradation of prothioconazole to take place to give 2-(1-chlorocyclopropyl)-1-(2-chlorophenyl)-3 -(1H-1,2,4-triazol-1-yl)propan-2-ol, as a result of which the proportion of active ingredient in the formulations is correspondingly reduced. Since the compound 2-(1-chlorocyclopropyl)-1-(2-chlorophenyl)-3-(1H-1,2,4-triazol-1-yl)ppropan-2-ol (hereinbelow referred to as desthio) is a relevant impurity, the content thereof in prothioconazole-containing formulations is subject to regulatory limitation.
Here, the maximum permissible amount of desthio in PTZ formulations depends on the amount of PTZ in the formulation in g/l. The maximum permissible amount of desthio is given in ppm, with the permissible proportion of desthio in ppm being half of the value of the PTZ load in g/l. Thus, the maximum permissible desthio content in a formulation with 100 g/l PTZ is 50 ppm (=0.005% by weight).
WO-A 2012/033590 discloses aqueous dispersions of prothioconazole containing a sulfur compound, for example L-cysteine, for stabilization.
The unpublished PCT/EP 2016/080215 (Bayer CropScience AG) is considered to be the closest prior art. What is described therein are emulsion concentrates comprising PTZ dissolved in a solvent. It was possible to stabilize the formulation by addition of formula (I)
Compounds of the formula (I) are known from WO-A 2012/061094 and can be prepared by the process of metathesis. These are, for example, products from Stepan ((N,N-dimethyl9-decenamide, CAS number: 1356964-77-6, Hallcomid® 1025 or Steposol® MET-10U).
These compounds have the disadvantage that they can only be prepared via a technically complex olefin metathesis step, that they comprise unwanted metal impurities which may catalyze the decomposition of active and inactive ingredients, and that compound I can only be used as solvent. Thus, alternative formulation types where PTZ is not dissolved (such as, for example, WG, SC, OD) are not accessible. Another disadvantage is the limited availability of products. Hitherto, the only industrial quantities of compound (I) available are of Hallcomid 1025.
WO 2016/092030 describes sugar surfactants having a 9-decenoyl radical for use in aqueous adjuvant compositions for increasing the efficacy of active electrolyte ingredients. Hereinbelow, the compounds described in WO 2016/092030 are referred to as glycoside surfactants having a 9-decenoyl radical.
There was therefore a need for stable PTZ-containing formulations, which, even over a relatively long period and under unfavorable storage conditions, for example oxygen contact, high temperatures or incidence of light, do not include any amounts of PTZ degradation products, in particular of 2-(1-chlorocyclopropyl)-1-(2-chlorophenyl)-3-(1H-1,2,4-triazol-1-yl1)propan-2-ol.
Accordingly, it was an object of the present invention to provide novel, improved prothioconazole-containing formulations which have high storage stability and do not exhibit any significant degradation rates of prothioconazole to give 2-(1-chlorocyclopropyl)-1-(2-chlorophenyl)-3-(1H-1,2,4-triazol-1-yl)propan-2-ol, where the formulations are free of compounds of formula (I).
In addition, the formulations are preferably free of glycoside surfactants having a 9-decenoyl radical. The present invention therefore provides formulations comprising

Application
Examples of administration forms include all the processes known as commonly used to the person skilled in the art: spraying, dipping, misting and a number of specific processes for direct treatment below or above ground of whole plants or parts (seed, root, stolons, stem, trunk, leaf), for example trunk injection in the case of trees or stem bandages in the case of perennial plants, and a number of specific indirect application processes.
The respective area- and/or object-based application rate of the crop protection compositions of a wide variety of different formulation types for control of the harmful organisms mentioned here varies very greatly. In general, the application media known to the person skilled in the art to be commonly used for the respective field of use are used in the conventional amounts for this purpose, for example from several hundred liters of water per hectare in the case of standard spraying processes through a few liters of oil per hectare in the case of ‘ultra low volume’ aircraft application down to a few milliliters of a physiological solution in the case of injection processes. The concentrations of the inventive crop protection compositions in the particular application media therefore vary within a wide range and are dependent on the respective field of use. In general, concentrations known to the person skilled in the art to be commonly used for the respective field of use are used. Preferred concentrations are from 0.01% by weight to 99% by weight, more preferably from 0.1% by weight to 90% by weight.
The agrochemical formulations of the invention can be deployed, for example, in the formulation forms customary for liquid preparations, either as such or after prior dilution with water, i.e., for example, as emulsions, suspensions or solutions. Application is effected by customary methods, i.e., for example by spraying, pouring or injecting.
Depending on the nature of the active ingredient possibly present in addition to prothioconazole, the formulations of the invention are useful for controlling a large number of pests and can be used either for treatment of plant crops or else for that of inanimate material and in the household.
“Pests” or “harmful organisms” are understood here to mean all kinds of pests which can be controlled or kept under control with organic crop protection active ingredients, i.e. crop protection agents, especially fungicides and mixtures of fungicides with other crop protection agents. The term “pest” therefore encompasses organisms that are harmful to plants, especially harmful fungi and their spores, but also harmful insects, arachnids, nematodes and harmful plants. The term “control” encompasses both curative treatment, i.e. the treatment of affected plants with a formulation of the invention, and protective treatment, i.e. the treatment of plants for protection from pest infestation.
The present invention thus also relates to the use of the formulations described herein for control of pests, especially plant pests, and to a method of controlling harmful organisms, especially plant-damaging organisms, comprising the contacting of the harmful organisms, their habitat, their hosts, such as plants and seed, and the soil, the area and the environment in which they grow or could grow, but also of materials, plants, seeds, soil, surfaces or spaces which are to be protected from attack or infestation by organisms that are harmful to plants, with an effective amount of the formulations of the invention.
A further aspect of the invention relates to the use of the formulations described herein for protection of plants including seed, especially useful plants, from infestation by harmful organisms, especially harmful fungi. The present invention thus also relates to the use of the formulations for control of plant-damaging organisms, for example harmful fungi, insects, arachnids, nematodes and harmful plants, especially for control of harmful fungi.
The formulations of the invention can be used in crop protection, particularly as foliar, seed-dressing and soil fungicides, in a manner known per se for control of phytopathogenic fungi.
Plants which can be treated with the formulations of the invention include the following: cotton, flax, grapevine, fruit, vegetables, such as Rosaceae sp. (for example pome fruits such as apples and pears, but also stone fruits such as apricots, cherries, almonds and peaches, and soft fruits such as strawberries), Ribesioidae sp., Juglandaceae sp., Betulaceae sp., Anacardiaceae sp., Fagaceae sp., Moraceae sp., Oleaceae sp., Actinidaceae sp., Lauraceae sp., Musaceae sp.

The formulations of the invention can be applied in undiluted form or diluted with water. In general, they are diluted with at least one part water, preferably with 10 parts water and more preferably with at least 100 parts water, for example with 1 to 10 000, preferably 10 to 5000 and more preferably with 50 to 24 000 parts water, based on one part of the formulation.
The present invention likewise provides an emulsion obtainable by mixing water with the liquid formulation of the invention. The mixing ratio of water to emulsion concentrate may be in the range from 1000:1 to 1:1, preferably 400:1 to 10:1.
The dilution is achieved by pouring the emulsion concentrates of the invention into the water. For rapid mixing of the concentrate with water, it is customary to use agitation, for example stirring. However, agitation is generally unnecessary. Even though the temperature for the dilution operation is an uncritical factor, dilutions are typically conducted at temperatures in the range from 0° C. to 50° C., in particular at 10° C. to 30° C. or at ambient temperature.
The water used for dilution is generally tap water. The water may, however, already contain water-soluble or finely dispersed compounds which are used in crop protection, for instance nutrients, fertilizers or pesticides.
It is possible to add various kinds of oils, wetting agents, adjuvants, fertilizers or micronutrients and further pesticides (e.g. herbicides, insecticides, fungicides, growth regulators, safeners) to the emulsion of the invention in the form of a premix or, if appropriate, not until shortly before use (tank-mix). These compositions may be added to the formulations of the invention in a weight ratio of 1:100 to 100:1, preferably 1:10 to 10:1.
The user will apply the formulation of the invention typically from a pre-dosing system, a backpack sprayer, a spraying tank, a spraying aircraft or an irrigation system; the formulation of the invention is typically diluted to the desired deployment concentration with water, buffer and/or further auxiliaries, which affords the ready-to-use spray liquid or agrochemical composition of the invention. Typically, 20 to 2000 liters, preferably 50 to 400 liters, of the ready-to-use spray liquor are deployed per hectare of useful agricultural area.
The required application rates of the pure active ingredients without formulation aids depend on the intensity of pest infestation, on the development phase of the plants, on the climatic conditions of the site of use and on the application method. In general, the application rate is in the range from 0.001 to 3 kg, preferably from 0.005 to 2 kg, more preferably from 0.01 to 1 kg and most preferably from 50 to 500 g of active ingredient per hectare, active ingredient here meaning prothioconazole plus possible further active ingredients.
The generally diluted formulations of the invention are applied mainly by spraying, especially spraying of the leaves. Application can be conducted by spraying techniques known to those skilled in the art, for example using water as carrier and amounts of spray liquor of about 50 to 1000 liters per hectare, for example from 100 to 400 liters per hectare.
The novel prothioconazole-containing formulations have advantageous properties in respect of the treatment of plants; more particularly, they feature good use properties, high stability and high fungicidal activity.
