Abstract
Abstract Chemically and physically stable insecticidal, nematocidal, water-soluble, liquid concentrates of (a) S-methyl-[(methylcarbamoyl)oxy]-thioacetimidate, and (b) methyl N',N'-dimethyl-N-[(methylcarbamoyl)oxy]-1-thiooxamimidate when dissolved in an appropriate solvent, preferably methanol and water, in the presence of a small amount of acid, display solubility synergism.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
99 words
An insecticidal and nematocidal composition of matter comprising (a) S-methyl-[(methylcarbamoyl)oxy]-thioacetimidate, and (b) methyl N',N'-dimethyl-N-[(methylcarbamoyl)oxy]-1-thiooxamimidate in a solvent, said solvent selected from solvent systems consisting of methanol/water containing from 0 to 70 weight percent water, acetone/water containing from about 0 to 70 weight percent water, and cyclohexanone/cyclohexanol/-methanol/water containing from about 20-92 weight percent cyclohexanone and cyclohexanol provided at least about 35% of this component is cyclohexanone, about 3-25 weight percent methanol and at least about 5 weight percent water, the ratio of (a) to (b) being 2:1 to about 1:21/2, said composition having a pH of about 2.8 to 3.2.
Claim 2
Dependent Claim
