摘要
为明确5种生物农药对海南甜瓜细菌性角斑病的田间防效,特开展本试验。试验结果表明,在甜瓜细菌性角斑病高发期施药2次,5亿CFU/g多黏类芽孢杆菌KN-03悬浮剂50倍液和20%春雷霉素水分散粒剂1500倍液在第2次药后5 d,防效分别可达到85.08%和76.52%,效果突出,可推广应用。
In order to clarify the field control efficacy of five biological pesticides on bacterial angular leaf spot of Hainan melon,the experiment was carried out.The results showed that the control efficacy of 500 million CFU/g Paenibacillus polymyxa KN-03 suspending agent 50 times liquid and 20%kasugamycin water dispersible granule 1500 times liquid could reach 85.08%and 76.52%respectively at five days after the second application.The efficacy was outstanding and these two biological pesticides could be popularized and applied.
