摘要: 为明确新型杀菌剂对葡萄霜霉病的田间防治效果,比较了10%氟噻唑吡乙酮可分散油悬浮剂、10%四唑吡氨酯悬浮剂、20%精甲霜灵悬乳剂、25%恶唑菌酮悬浮剂和30%恶酮·精甲霜灵悬乳剂5种杀菌剂的防治效果。结果表明,10%氟噻唑吡乙酮可分散油悬浮剂对葡萄霜霉病的田间防治效果优于其他4种杀菌剂,可达80%以上,可作为推荐用药。其他4种杀菌剂防治效果均在70%以上,其中30%恶酮·精甲霜灵悬乳剂的防治效果优于10%四唑吡氨酯悬浮剂,但二者防治效果差异不显著。

Abstract: To clarify the field control effects of novel fungicides against grape downy mildew, a field experiment was conducted to compare the control effects of five test fungicides: 10% oxathiapiprolin dispersible oil suspension, 10% picarbutrazox suspension concentrate, 20% metalaxyl-M suspension emulsion, 25% famoxadone suspension concentrate, and 30% metalaxyl-M + famoxadone suspension emulsion. The results showed that 10% oxathiapiprolin dispersible oil suspension exhibited the highest control efficacy, exceeding 80%, and could be recommended for controlling grape downy mildew. The other four fungicides also demonstrated control efficacies above 70%. Among these four, 30% metalaxyl-M + famoxadone suspension emulsion showed better performance than 10% picarbutrazox suspension concentrate, although the difference was not statistically significant.
