葡萄霜霉病有效药剂筛选及综合防控技术

Screening of Effective Agents and Integrated Control Techniques for Grape Downy Mildew

选取5种药剂进行田间试验,筛选生物与化学新药剂或新剂型用于科学防控葡萄霜霉病。结果表明:生产上用来防治葡萄霜霉病较频繁的酰胺类杀菌剂烯酰吗啉和霉多克、喹啉铜等仍具有较好的防效;新型复配药剂60%吡唑醚菌酯·代森联水分散粒剂在试验药剂中防效表现突出,生物杀菌剂多抗霉素药后7天防效接近80%,是防治葡萄霜霉病的有效生物杀菌剂。同时针对病害发生特点对其综合防控技术进行了研究集成。

Five kinds of medicaments were selected for field experiments to screen new biological and chemical agents or new dosage forms for the scientific control of grape downy mildew. The results showed that the amide fungicides such as dimethomorph,Meiduoke and oxine-copper,which are frequently used to control grape downy mildew in the production,still had good control effects. The new compound 60% Pyraclostrobin& dithane Water Dispersibie Granua showed outstanding anti-effervescent effect in the test chemicals. The antibacterial effect of the multi-antimicrobial biocide was nearly 80% seven days after the antibacterial agent was applied. It is an effective biocide for controlling grape downy mildew. At the same time,according to the characteristics of disease occurrence,the integrated prevention and control technology was researched and integrated.
