Process for the preparation of spherical microparticles containing

Coated microparticle agglomerates

Multiply-coated particles

The invention relates to a novel formulation of per se known pesticides in the form of microcapsules, to a process for the preparation of microcapsules and to the use of said microcapsules for controlling weeds, plant diseases, insects and representatives of the order Acarina.

Pesticidal formulations

A process for the preparation of microcapsules, which comprises rapidly stirring an aqueous solution of a precondensate of urea and a dialdehyde in the molar ratio of urea to dialdehyde of 1:1 to 1:2.5, into an acidified aqueous dispersion of a water-immiscible pesticide or a readily volatile water-immiscible solvent.

Microcapsulated pesticidal formulations, their preparation and use

The invention relates to aqueous formulations containing 1 to 70% by weight of an agrochemical active substance which is sparingly soluble in water, besides an amount which inhibits crystallization of the active substance or breaking of the emulsion, of a compound of the formula I

Aqueous formulations and their use

Salts of formamidines with polymers containing sulfonic acid groups; processes for producing these salts; and the use thereof in combating pests.

Salts formed from formamidines with polymers containing sulfonic acid

Salts of 3-methyl-2-(2',4'-dimethyl-phenylimino)-4-thiazoline with polymers containing sulfonic acid groups, processes for producing them, and their use in combating pests.
