Description

CONCENTRATE OF NON-AQUEOUS SUSPENSION DESCRIPTION OF THE INVENTION This invention pertains to a non-aqueous stable suspension concentrate (SC) for active crop protection compounds, a method for the manufacture of such suspensions and their use for combating pests. As a rule, the inert ingredients should be used to provide active crop protection compounds, for example fungicidal compounds in a form that the user can apply, either as such or after dilution with water. The correct selection of the proper inert, ingredients, such as carriers, for the formulation is often determined to a significant degree if the active ingredient exhibits its full efficiency in the application. Not every active ingredient is suitable for use in any given formulation, because the efficiency and physiochemical stability of the active ingredient can be affected by other ingredients in the formulation. the efficiency of the active components can often be improved by the addition of other ingredients. The observed efficiency of the ingredient combination can sometimes be significantly greater than would be expected from the amounts of the individual ingredients used (synergism). An adjuvant is defined in the present as a substance which can increase the biological activity of an active ingredient but is not in itself significant and biologically active. The adjuvant can be included in the formulation or can be added separately, for example to spray a tank together with the formulation containing the active ingredient. For ease and safety of handling and dosing of these adjuvants by the end user, and to avoid unnecessary packing material, it is desirable to develop concentrated formulations that already contain such adjuvants. International Patent Application WO 95/01722 discloses aqueous pesticidal formulations containing nonionic dispersants selected from block polymers having a polyoxypropylene core, an anionic dispersant, and a wetting agent selected from polyalkoxylated fatty alcohols. However, it is not established that these wetting agents improve the activity of pesticides. In addition, there is no description of non-aqueous suspension concentrates.

Another aspect of the present invention is a process for the preparation of the SC described above, which comprises: (a) an air grinding component (a) optionally in the presence of the component (e), and / or a grinding aid such as kaolin or silica; and (b) mixing all components (a) to (c), (d) and / or (e) and, optionally, (f) in a mixer. In addition, the invention relates to a method for controlling pests in a location which comprises diluting a SC according to the invention with water and treating the site with an effective amount of the diluted formulation.
