CONTROLLED RELEASE PESTICIDAL GRANULES COATED WITH BIODEGRADABLE POLYMER OF LOW MELTING POINT OR AMORPHOUSNESS AND PROCESS FOR PRODUCING THE SAME

PURPOSE: Controlled release pesticidal granules coated with biodegradable polymer of low melting point or amorphousness and a process for producing the same pesticidal granules are provided, thereby effectively controlling plant pathogenic bacteria by spraying the controlled release pesticidal granules at one time, so that problems such as poison and environmental pollution can be significantly reduced. CONSTITUTION: The controlled release pesticidal granules comprises a mineral support and a coating layer which coats the mineral support, wherein the coating layer comprises one or more pesticidal compounds and biodegradable polymer of low melting point of 40 to 70 deg. C or amorphousness; the biodegradable polymer is aliphatic polyester polymer of formula (1), polycaprolactone(PCL) or biodegradable polyester urethane in which a and b are polymerization degree and integer of 0 or 1 or more, provided that a+b is 30 or more, m is an integer of 1, R2 and R3 are independently dicarboxylic acid, and R1 is diol; and the aliphatic polyester polymer is selected from PBA(poly(butylene adipate)) monopolymer, PEA(polyethylene adipate) monopolymer, PBSA(poly(butylene succinate-co-butylene adipate)) copolymer and PESA(poly(ethylene succinate-co-ethylene adipate)) copolymer.
