EFFICACY OF ACETAMIPRID 2-PERCENT GRANULE AGAINST DIAMONDBACK MOTH ONCABBAGE BY SOIL TREATMENT

Acetamiprid, 3-pyridyl)methyl]-N-2-cyano-N-1-methylacetamidine, posses ses a broad insecticidal spectrum and excellent systemic activity. For the purpose of finding the practical way of application that makes th e best use of the potential of acetamiprid, the efficacy of acetamipri d against larvae of the diamondback moth by soil treatment, mainly the planting hole application, was investigated. Release controlled granu le was investigated to improve the efficacy of release uncontrolled fo rmulation. The improved formulation provided an excellent efficacy wit hout 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 effica cy against the diamondback moth by the nursery box application. The gr anule was expected to have the potential for more practical usage in s oil treatment for the excellent efficacy with planting hole applicatio n and nursery box application.
