摘要
测定嘧菌酯、锰锌·霜脲、烯酰吗啉·锰锌、唑菌酮·霜脲、氟吗啉·代森锰锌和霜·锰锌6种杀菌剂防治设施和露地黄瓜霜霉病。结果表明:杀菌剂对设施和露地黄瓜霜霉病的防治效果有一定差异。其中72%锰锌·霜脲WP(制剂用量1999.5g/hm2)和25%嘧菌酯SC(制剂用量600g/hm2)对露地和黄瓜霜霉病防治效果均显著,在发病前或发病初期每隔7d施药1次,共3次,防效均在77%以上;52.5%唑菌酮·霜脲WG(制剂用量750g/hm2)对黄瓜霜霉病的防效露地栽培明显高于设施栽培。
Field experiment of amistar, mancozeb.cymoxanil, dimethomorph.mancozeb, famoxadone-cymoxanil, fiumorph-mancozeb and oxadixyl.mancozeb on cucumber downy mildew in protective area and field were examined. The results of field experiment showed that control efficacy was differences of fungicides on controlling downy mildew of protective area and field cucumber. Mancozeb.cymoxanil 72% WP （1999.5 g/ha） and azoxystrobin 25% SC （600 g/ha） had higher control efficacy on control of cucumber downy mildew, before disease coming on, per 7-10 days apply fungicides 1 times and total of 3 times, the prevention effect go beyond 77%. Control efficacy of famoxadone＇cymoxanil 52.5% WG （750 g/ha） on cucumber downy mildew was field cultivation more higher protective area cultivation.
