Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
106 words
A process for preparing an insect-repellent and insecticidal article for breeding plants which comprises forming a clathrate compound consisting of fenitrothion (O,O-dimethyl O-(3-methyl-4-nitrophenyl) thiophosphate) or a pyrethroid insecticide included in cyclodextrin or a starch hydrolyzate containing cyclodextrin; drying and powdering the obtained clathrate compound; melting 0.1 to 50% by weight of the obtained powder together with a synthetic resin compound which can be molded at a temperature lower than the decomposition temperature of the fenitrothion or pyrethroid insecticide; pelletizing the mixture and molding the pellets into the shape of a desired article at a temperature lower thant the decomposition temperature of the fenitrothion or pyrethroid insecticide.
