Insecticidal and nematocidal compsn. - contg. s-methyl-(methylcarbamoyloxy)-thio:acetimidate, methyl-(n',n)-di:methyl-(n)-(methylcarbamoyloxy)-thio:oxamimidate and solvent

摘要

An insecticidal and nematocidal compsn. comprises (a) S-methyl- (methylcarbamoyl)oxy -thioacetamidate, and (b) methyl N', N'-dimethyl - N - (methylcarbamoyl)oxy -1-thiooxamimidate in a solvent. The solvent systems is methanol/water contg. 0-70 wt.% water, acetone/water contg. 0-70 wt.% water, and cyclohexanone/cyclohexanol/-methanol/water contg. 20-92 wt.% cyclohexanone and cyclohexanol =35% of this component is cyclohexanone, about 3-25 wt.% methanol and =5 wt.% water. The ratio of (a) to (b) is 2:1 - 1:2-1/2, the composition is maintained at a pH of 2.8 - 3.2.
