摘要
利用依天得(1000亿个/g芽孢杆菌可湿性粉剂)以不同浓度防治黄瓜白粉病,经试验结果表明,用依天得40、60g/667m2防治黄瓜白粉病,均有较好的防治效果,尤以60g/667m2的防治效果较好,与化学农药20.0%三唑酮乳油60g/667m2的防效相当,生产中可以使用生物农药依天得取代化学农药,从而提高农产品的质量安全。
According to pesticide of (1 00 billion/g bacillus wettable powder) with different concentrations controlling cucumber powdery mildew, the test results show that according to the day with 40 to 60 g/667 m2, controlling cucumber powdery mildew, all have good control effect, especially in 60 g/667 m2 prevention and cure effect is better, and the chemical pesticide 20% beta-cypermethrin triadimefon 60 g/667 m2 control effect quite, the production of can use biological pesticide in day to replace the chemical pesticide, so as to improve the quality and safety of agricultural products.
