南四湖地区甜瓜病虫害防治中的农业面源污染防控研究

摘要

A field experiment was carried out to study disease and pest control efficiency, economic benefit and environmental benefit in melon powdery mildew, frosty mildew, anthracnose ,etc, fungal disease control throughout biological pesticide green substitution and pesticide reduction with accurate use, for the purpose of providing the basis of pesticide green substitution and reduction dosage in agricultural disease and pest control, preventing or slowing down agricultural non-point source pollution for the region.%通过生物农药绿色替代和农药减量与精准施用技术应用,研究其在甜瓜白粉病、霜霉病、炭疽病等真菌病害防治中的病虫防治效果、经济效益、环境效益,为地区农业病虫防治中农药替代、减施增效,防止或减缓农业面源污染提供依据.
