对不同浓度70％甲基硫菌灵可湿性粉剂进行黄瓜白粉病防治田间试验研究.结果表明：在黄瓜白粉病发病初期,1 hm2用70％甲基硫菌灵可湿性粉剂的525～ 630g,对水750kg,对黄瓜白粉病有较好的防治效果.喷药间隔期为7d,共喷3次.药后7d各处理防效分别78.78％～80.54％,且对黄瓜生长安全.
With different concentration of 70% thiophanate -methyl WP to control cucumber powdery mildew in the field, the result show that it was the high control efficiency to cucumber powdery mildew as it was early stage with 70% thiophanate - methyl WP 525 -630g/hm^2added water 750kg. thiophanate - methyl WP were sprayed three times, the interval was 7 days.
