Abstract

The invention relates to water-emulsifiable granules of crop protection agents composed of the pesticidal active substance in liquid or dissolved form and an at least partially water-soluble shell-forming structural material, to the use of these granules as novel, advantageous formulations of crop protection agents, and to processes for their preparation. It furthermore relates to the general use of polyvinyl alcohols as shell-forming structural materials in the preparation of water-emulsifiable granules which contain organic compounds dissolved in a high-boiling solvent or solvent mixture.

Dependent claims

Water-emulsifiable granules having an average particle diameter of 0.3 to 5 mm, which granules comprise

2 to 70% by weight of a pesticidally active substance which is not soluble, or which is only sparingly soluble in water, selected from the group consisting of herbicides, safeners, insecticides, fungicides, acaricides, nematicides, pheromones and repellants,
20 to 80% by weight of a high-boiling solvent or solvent mixture, and
10 to 80% by weight of an at least partially water-soluble shell-forming structural material, which shell-forming structural material is comprised of a polyvinyl alcohol obtained by partial hydrolysis of polyvinyl acetate, or of a mixture of such polyvinyl alcohols, and which granules do not contain deltamethrin as the pesticidally active substance.
