PURPOSE:To obtain the subject agent having extremely high stability, low toxicity and high insecticidal effect and applicable without troubles by adding a water-miscible solvent and an allylalkane compound having >=2 phenyl groups to bensultap and converting the mixture into emulsifiable concentrate or wettable powder. CONSTITUTION:An agricultural insecticide having excellent emulsion stability and insecticidal effect can be produced by adding an allylalkane compound having >=2 phenyl groups (e.g. phenylxylylethane) and a water-miscible solvent to bensultap [1,3-bis(benzenesulfonylthio)-2-(N,N-dimethylaminoipropane]. The amounts of the allylalkane compound and the water-miscible solvent are preferably 0.05 to 1 pts.wt. and 0.1 to 5 pts.wt. per 1 pt.wt. of bensultap, respectively. The precipitation of bensultap crystal in the emulsifiable concentrate or wettable powder does not take place during the storage or the preparation of spraying liquid. Furthermore, the agent does not clog the spray-nozzle of a sprayer and exhibits excellent insecticidal effect. |
