Pesticidal aqueous suspension

摘要

A pesticidal aqueous suspension having an excellent dispersion stability, which comprises, as a pesticidally active ingredient, an N-methyl- or N-phenylcarbamate which is solid and has a solubility in water of about 10 to 10,000 ppm at room temperature, suspended in water in a finely dispersed state with a surfactant having a hydrophilelipophile balance (HLB) less than 5 and polyvinyl alcohol having a degree of hydrolysis of about 70 to 90 mol % and a degree of polymerization of about 300 to 2,600 as dispersing agents in the presence of ethylene glycol and liquid paraffin as dispersion stabilizers.
