Acetamiprid, (E)-N1-[(6-chloro-3-pyridyl)methyl]-N2-cyano-N1-methylacetamidine,, possesses a broad insecticidal spectrum and excellent systemic activity. For the purpose of finding the practical way of application that makes the best use of the potential of acetamiprid, the efficacy of acetamiprid against larvae of the diamondback moth by soil treatment, mainly the planting hole application, was investigated. Release controlled granule was investigated to improve the efficacy of release uncontrolled formulation. The improved formulation provided an excellent efficacy without fluctuating depending on the soil type and rainfall. The efficacy of acetamiprid 2% granule against larvae of the diamondback moth was superior to that of benfuracarb 5% granule and acephate 5% granule by the soil treatment. Moreover, the granule showed an outstanding efficacy against the diamondback moth by the nursery box application. The granule was expected to have the potential for more practical usage in soil treatment for the excellent efficacy with planting hole application and nursery box application
