摘要
研究了银法利687.5 g/L悬浮剂防治辣椒疫病的田间药效。结果表明：银法利687.5 g/L悬浮剂1 125 g/hm^2对水675-1 800 kg/hm^2喷雾,对辣椒植株安全,防治辣椒疫病效果可达72.15%-85.19%。生产上经济用量为银法利687.5 g/L悬浮剂1 125 g/hm^2对水1 125 g/hm^2。
The field trial effect on 687.5 g/L Yinfali suspension to pepper phytophthora blight was tested. Results showed that spraying Yinfali suspension with concentration 1 125 g/hm^2 adding with water 675 to 1 800 kg/hm^2 on pepper plants were safe. The control effects were from 72. 15% to 85.19%. The optimum dose was 687. 5 g/L Yinfali suspension with concentration 1 125 g/hm^2 adding with water 1 125 kg/hm^2.
