Insektizides Mittel

A stabilized insecticidal composition comprises a finely-divided solid carrier, e.g. kaolin, montmorillonite and attapulgite clay, an organic phosphate insect toxicant having the formula wherein R1, R2 and R3 are lower alkyl radicals of not more than 4 carbon atoms; or the formula wherein Alk is a...

Beschreibung
Zusammenfassung:	A stabilized insecticidal composition comprises a finely-divided solid carrier, e.g. kaolin, montmorillonite and attapulgite clay, an organic phosphate insect toxicant having the formula wherein R1, R2 and R3 are lower alkyl radicals of not more than 4 carbon atoms; or the formula wherein Alk is an alkyl radical selected from the group consisting of methyl, ethyl, n-propyl, i-propyl and t-butyl, and an effective amount of a polyalkylene glycol, e.g. ethylene glycol, propylene glycol, butylene glycol, diethylene glycol, triethylene glycol, polyethylene glycol, to prevent deactivation of the toxicant by the carrier. Preferably the toxicant is present in an amount from 1-30% and the glycol from 1-20% based on the weight of the carrier. Specified toxicants are O,O-diethyl S-(ethylthiomethyl) phosphorodithioate, S-(N-methyl-carbamoylmethyl) O,O-dimethyl-phosphorodithioate.
