摘要
通过田间小区试验和同田对比试验,研究了烯酰吗啉、安泰生、嘧菌酯、氟菌.霜霉威、霜脲氰.锰锌5种杀菌剂对葡萄霜霉病的防治效果.田间小区试验表明:50%烯酰吗啉SC 3 000倍液和70%安泰生WP 700倍液对葡萄霜霉病的防效极显著,且持效期长,药后5、10、20d的防效分别为91.98%、88.41%、67.15%和85.71%、78.53%、60.09%,防效显著高于其他3种药剂;同田对比试验表明:50%烯酰吗啉SC 3 000倍液和70%安泰生WP 700倍液对葡萄霜霉病的防效较好,药后3、7d防效分别为93.17%、83.33%和85.99%、73.59%,防效明显优于其他3种药剂;5种杀菌剂防效顺序依次为:烯酰吗啉>安泰生>霜脲氰.锰锌>嘧菌酯>氟菌.霜霉威.
The control effects of five novel fungicides against Plasmopara uiticola were tested in fields.The field experiment showed that：50% dimethomorph SC 3000 times and 70% propineb WP 700 times appeared a significantly control efficacy to grape downy mildew and had a longer efficacy duration.The control efficacy were 91.98%,88.41%,67.15% and 85.71%,78.53%,60.09% respectively after 5,10 and 20 days treatments,which were significantly higher than cymoxanil-mancozeb,azoxystrobin and fluopicolide-propamocarb.50% dimethomorph SC 3000 times and 70% propineb WP 700 times appeared a higher control efficacy to grape downy mildew comparing to the field experiment without fungicides treatment.The control efficacy was 93.17%,83.33% and 85.99%,73.59% after 3 and 7days of treatments respectively,which were much higher than the other three fungicides.The control efficacy of five fungicides arranged as dimethomorphpropinebcymoxanil-mancozebazoxystrobinfluopicolide-propamocarb.
