5种杀菌剂对葡萄霜霉病的控制效果

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、20 d的防效分别为91.98％、88.41％、67.15％和...

Control effect of five fungicides against Plasmopara uiticola

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 dimethomorph>propineb>cymoxanil-mancozeb>azoxystrobin>fluopicolide-propamocarb.
