  • Publication number: 20170354142
    Abstract: A formulated composition suitable for controlling or preventing pathogenic damage in a plant comprising (A) at least one solid active ingredient having a water solubility of at most 100 ?g/litre at 25° C. at neutral pH, in an amount of at least 1 weight %, based on the total weight of the formulated composition, (B) at least one non-ionic surface active compound having a hydrophile-lipophile balance (HLB) of between 10 and 18, one or more customary formulation auxiliaries, and water; wherein active ingredient (A) is suspended or dispersed in the water, the weight ratio of surface active compound (B) to active ingredient (A) is in the range of from 1.5 to 15.0, provided the minimum amount of surface active compound (B) is at least 6 weight %, based on the total weight of the formulated composition. Also a method of improving pesticide residue levels in agriculture.

  • Patent number: 5866153
    Abstract: The invention relates to a process for the preparation of an aqueous suspension of microcapsules having a capsule wall of polyurea and encapsulating a water-immiscible pesticide, by dispersing a solution of a polyisocyanate in the sparingly water-soluble pesticide in water and subsequently reacting the dispersion with a polyamine, which process comprises effecting the dispersion of the solution of the polyisocyanate in the sparingly water-soluble pesticide in water and the subsequent reaction of the dispersion with the polyamine in the presence of at least one water-soluble or water-dispersible nonionic surfactant of a block copolymer having at least one hydrophobic block and at least one hydrophilic block.
