Abstract

Experiments of control effects were carried out against potato blast with six chemicals such as, 30% No.3 Bingchongjing, 64% Oxadixyl mancozeb, 25% metalaxyl WP, 50% fosetyl-Al-Mn-Zn, 72% Du Pont Curzate and 50% mancozeb.The results showed that 30% No.3 Bingchongjing was the best chemical to control effect potato blast. Its control efficiency was 71.95% . The next were 72% Du Pont Curzate and of 25% metalaxyl WP. Their control efficiency were 71.22% and 61.59% respectly. The worst one was to control effects with 64% mancozeb, Its control efficiency was only 47.18%.
