GRANULAR COMPOSITIONS AND METHODS FOR COMBATTING RICE PESTS AND FUNGAL DISEASES

摘要

This invention relates to a method for combating rice pests and/or fungal diseases, which comprises applying to an aqueous medium, in which rice is grown, a granular composition obtainable by preparing one or more melts comprising: 1-60% by weight of an appreciably water-soluble insecticidal or fungicidal active ingredient or a combination of such active ingredients, and optionally one or more other insecticidal or fungicidal active ingredients, 0-70% by weight of at least one inert carrier, 0-50% by weight of one or more organic or inorganic additives, and 20-80% by weight of at least one thermoplastic, water- insoluble polymer, to a total of 100% by weight; extruding or co-extruding the melt or melts and granulating the extrudate. It also relates to a controlled release composition for use therein.
