在果肉中均未检出有残留，即使采用最高浓度250倍，最多5次，最短距收期3d，在果和土壤中的残留也仅分别0.3657-0.3735mg·kg^-1和0.4219-0.4831mg·kg^-1，参照欧共体规定代森锰锌MRL值0.5mg·kg^-1，分析结果均在允许值范围内。

We adopted many forestry techniques, including scarifying, weeding, draining, fertilizing, digging far-between dyke, choosing and breeding eximious clone. We also took measures of excavating aperture and irragating root, directly watering root, daubing remedy, stubbing died trees and sterilizing soil in the aperture.We carried through integrated preventional measures of chemical prevention and biological prevention, by using 200×CuSO4, 70% mancozeb 800×5% Chlorothalonil 800×, and Suillus grevillei. All of the meaures got favorable results. The preventional effect exceeded 72%. The incidence of disease descended from 15.5% in 1998 to 2.8% in 2002.This kind of disease was controlled on the whole.
