摘要： 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.

摘要： PURPOSE:A stable carrier for agricultural chemical having a large adsorption amount of active component of agricultural chemical, providing an agricultural chemical with low production cost, obtained by grinding rough stone such as basalt, andesite, sandstone, quartz porhyry, etc., into a specific particle size range by the same method as than for production of ground aggregate. CONSTITUTION:Impurities are removed from rough stone such as basalt, andesite, sandstone, quartz porphyry, etc., pulverized by using successively a crusher for grinding large mass, a crusher for middle grinding and a crusher for fine grinding, and classified, to give ground sand having a particle size (0.1-2.0mm particle diameter) passing through 9 meshes and not passing 150 meshes as a carrier for agricultural chemical. This carrier is used for inserticide, fungicide, herbicide, plant growth regulator, etc., stable, stands long-term storage and transportation, has a large adsorption amount of active component and high elution ratio, so agricultural chemicals with uniform size and uniform qualities can be economically obtained at low manufacturing cost.
