在加拿大安大略省,广泛应用代森锰锌来防治葡萄霜霉病。但因代森锰锌与其它二硫代氨基甲酸酯杀菌剂混合物能转化为有毒的乙撑硫脲,这就限制代森锰锌的继续使用,故需要一种替换代森锰锌的杀菌剂。已证明,百菌清(四氯间苯二腈)对防治葡萄霜霉病和白粉病是有效的。本报告是测定百菌清的残留量,剂型对叶片病害的防治效果及对果实品质的影响。
In Ontario, Canada, mancozeb is widely used to control grape downy mildew. However, because mancozeb and other dithiocarbamate fungicide mixtures can be converted into toxic ethylene thiourea, which limits the continued use of mancozeb, there is a need for an alternative bactericidal effect of mancozeb Agent. Chlorothalonil (tetrachloroisophthalonitrile) has proved to be effective against grape downy mildew and powdery mildew. This report is the determination of chlorothalonil residues, dosage forms of leaf disease prevention and control effects and the impact on the quality of the fruit.
