| 中文摘要: |
| 葡萄白粉病( Uncinula necator )是造成云南葡萄减产品质降低的主要病害之一,特别是在金沙江干热河谷早熟葡萄产区,白粉病的流行会使葡萄减产30%,严重减产50%。通过田间试验对几种药剂对葡萄白粉病防效进行比较,从而选出防效较好的药剂。第1次药后7d,新高脂膜粉剂防治效果最高,达42.92%。第2、3、4次药后,15%三唑酮防治效果最高,分别达到51.50%、57.86%、51.81%,其余生物药剂防治效果都未达到50%,存在显著性差异。 |
| 英文摘要: |
| Uncinula necator of grape is one of the main diseases which cause the decrease of grape yield and quality in Yunnan,Especially in the early maturing grape producing areas of Jinsha river hot valley,the prevalence of powdery mildew will reduce the yield of grapes by 30%, and reduce the yield by 50%。Field experiments were conducted to compare the control effects of several insecticides on grape powdery mildew, and to select the fungicides with better control effect. On the 7th day after the first drug treatment, the prevention and cure effect was the highest, up to 42.92%. The control effect of 15% triadimefon reached 51.50%, 57.86% and 51.81% respectively, but the other biological agents did not reach 50%, there was significant difference. |
