UNIFORMLY DISPERSIBLE GRANULAR AGROCHEMICAL PREPARATION AND METHOD FOR SPRAYING THE SAME PREPARATION

摘要

PROBLEM TO BE SOLVED: To establish uniformly dispersible granular agrochemical preparation, premised on local spraying, having good dispersibility of a agrochemical active ingredient and capable of obtaining desired agrochemical treating effect even when algae, etc., are blown together and water surface of paddy field, etc., is covered by algae, etc., and a method for spraying the preparation.;SOLUTION: This uniformly dispersible granular agrochemical preparation comprises an agrochemical active ingredient and has a particle size distribution in which particles having ≥3 mm particle diameter occupy 80% and property floating on water surface and disintegrates on the water surface within 30 min. This method for spraying uniformly dispersible granular agrochemical preparation comprises spraying the preparation over an area of 5% to 50% based on total paddy field area at distance separated by ≥1 m from levee of paddy field under flooding.;COPYRIGHT: (C)2002,JPO
