Abstract
The controlling effects of several chemicals(dose) on grape downy mildew were comparatively studied.The results showed that 72.2% Baolike diluted 600 times,10% Ankemengxin diluted 750 times and 72% Jiashuanglingmengxin of 600 times all had good effects on the control of downy mildew of grape,which was significantly superior than traditional chemicals such as 25% Jiashuangling diluted 500 times.Among them,the effect of(72.2%) Baolike diluted 800 times was most excellent in comparison with other treating chemicals.
