生物农药[大豆油和蛋黄(Soybean oil and lecithin,SOL)]对黄瓜白粉病具有防治作用,本试验通过盆栽与大棚试验对SOL生物农药最适稀释浓度进行筛选,其中SOL300组表现出优异的防治效果,盆栽试验预防效果达到100%,治疗效果达到了97.54%;大棚试验发病初期治疗效果为86.09%,发病中期为60.84%。同时,SOL 300倍的防治效果显著高于甲基硫菌灵的防治效果。试验结果表明,SOL生物农药的最适稀释浓度为300倍。
Biopesticide [Soybean oil and lecithin (SOL)] has the preventive and curative effect on cucumber powdery mildew. In this experiment, the optimum concentration of SOL biopesticide was screened by pot and greenhouse test. Among them, SOL300 group showed excellent control The results showed that the preventive effect of pot experiment reached 100% and the treatment effect reached 97.54%. The initial treatment effect was 86.09% and the incidence was 60.84% in the greenhouse experiment. At the same time, the control effect of 300 times of SOL was significantly higher than that of thiophanate-methyl. The test results show that the optimum concentration of SOL biological pesticides diluted 300 times.
