防治烟草黑胫病常用农药残留量与降解的研究
The degradation dynamics and residue level of different germicides against tobacco black shank
摘要
Abstract
Degradation dynamics and residue level of metalaxyl, dimethomorph, propamocab, mancozeb and phosetyl-Al in tobacco leaves were studied using data from two years' CAP field trials in Shandong. Results showed that degradation speed of 5 germicides was fast, with half-life of 0.7 ~ 3.2 days. Trial dosage, spray times and harvest time after the last trial were the most important factors, and single factor and multiple factors are prominent in different germicide. Residue level in tobacco leaves were lower than CORESTA guidance level if the right dosage was applied in appropriate time,关键词
