摘要
为筛选高效低毒且对甜瓜细菌性果斑病防效较佳的农药试剂,以砂地甜瓜为研究对象,对 9 种高效低毒杀菌剂进行了田间筛选试验.结果表明,供试的 9 种药剂对甜瓜细菌性果斑病均具有一定的防治作用.77%硫酸铜钙可湿性粉剂 500 倍液第 1 次和第 2 次喷药 7d后防效均在 70%以上,且第 2 次防效比第 1 次上升 1.55个百分点,防治效果最佳.建议在白银市甜瓜果斑病防治中优先选用 77%硫酸铜钙可湿性粉剂 500 倍液喷雾防治.
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.
