Abstract: Provided is a granular agrochemical composition by which the problems accompanying the prior art granular agrochemical compositions can be overcome, which can be prepared in a simple formulation and by which sustained releasability of the agrochemically active ingredient is obtained so that the load on the environments can be decreased and the chemical damages caused by the agrochemically active ingredient can be alleviated or prevented. The granular agrochemical composition contains an acidic agrochemically active ingredient, a cationic surfactant and a basic substance. Inter alia, a pH of 5 or higher is obtained in a 1% by mass aqueous suspension thereof. Preferably, the acidic agrochemically active ingredient should have a pKa of 2 to 7 and the cationic surfactant should be one which is gelled or exhibits swellability in water.

Abstract: As a novel, agricultural or horticultural granular composition having a low foamability and comprising a granular wettable powder, that is, water-dispersible granules which can have an improved disintegrability in water, an improved dispersibility in water and an improved suspensibility in water, irrespective of the nature and the property of the agrochemically active ingredient as incorporated, there is provided an agricultural or horticultural granular composition comprising as the essential components, (a) at least one of an agrochemically active ingredient, (b) at least one of a surfactant selected from a sulfonate-type surfactant, a sulfate-type surfactant and a phosphate-type surfactant, and (c) at least one of a metal salt of a fatty acid of 6 to 28 carbon atoms. An aqueous dispersion which may be prepared by diluting the composition of the present invention with water has a low foamability.
