9种杀菌剂对甜瓜细菌性果斑病的田间防效
Field Efficacy of Nine Bactericides against Acidovorax citrulli in Muskmelons
摘要
Abstract
In order to screen efficient and low toxicity pesticide reagents with better control effect on Acidovorax citrulli of muskmelon,in this experiment,the muskmelon in sandy land of Baiyin City was taken as the research object,and the field screening test was carried out on 9 kinds of highly effective and low toxic bactericides.The 9 tested bactericides all had certain preventive and therapeutic effects on Acidovorax citrulli in muskmelons.Control effects after 7 days using 77%Copper(Ⅱ)sulfate calcium wettable powder 500 times dilution for 1-time and 2-time spray were all above 70%,and the 2-time control effect was 1.55 percent higher than that of the 1-time treatment,which showed the best control effect.Therefore,spraying 77%Copper(Ⅱ)sulfate calcium wettable powder 500 times dilution are recommend in the prevention and control of muskmelon Acidovorax citrulli in Baiyin City.关键词
