The Effect of Suspension Concentrate of Ginkgolic Acid on Melon Powdery Mildew

为了明确银杏酚酸对甜瓜白粉病的防治效果及使用剂量,选取10%银杏酚酸悬浮剂(Suspension concentrate,SC),以40%氟硅唑SC和80%多菌灵可湿性粉剂(Wettable powder, WP)作对照,采用田间试验,研究了10%银杏酚酸SC防治甜瓜白粉病的效果。结果表明,10%银杏酚酸SC对甜瓜白粉病具有良好防效,最佳使用剂量为16 g/667 m^2,防效优于80%多菌灵WP,且对甜瓜生长安全,是防治甜瓜白粉病较理想的生物药剂之一。

To discover the effect of suspension concentrate of ginkgolic acid （GASC） on melon powdery mildew, this study a fieldcari-ied out experiment using the treatment of 10% GASC, compared with the controls of 40% suspension concentrate of flusilazole and 80% wettable powder of carbendazim. The results showed that 10% GASC had an better effect on melon powdery mildew under the dosage of 16 g/667 m2 than that of 80% wettable powder of carbendazim, which was a perfect biological agent for melon powdery mildew.
