Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
127 words
A composition comprising an insecticidally and nematocidally effective amount of an organothiophosphorus compound having the following general formula: (RS).sub.2 P(O)OR' wherein R' is selected from the group consisting of methyl and ethyl, R is selected from the group consisting of propyl and butyl when R' is methyl, and R is propyl when R' is ethyl, a solid particulate attapulgite clay carrier therefor and a mixture of from about 2 to 10 weight percent, by weight of the total composition, of propylene glycol and from about 2 to 10 weight percent, by weight of the total composition, of an acid selected from the group consisting of acetic acid, acrylic acid, ethylhexanoic acid, and formic acid; wherein said propylene glycol and said acid are present in equal weight amounts.
