摘　　要：为有效防治西瓜幼苗果斑病,以西瓜幼苗为试验材料,研究了不同浓度可杀得叁千叶面喷施对西瓜幼苗细菌性果斑病发病率的影响。结果表明:随着浓度升高,可杀得叁千对西瓜幼苗细菌性果斑病的防治效果逐渐增强,但浓度过高(9.4 mmol·L^-1以上)对西瓜幼苗会产生药害。适宜浓度的可杀得叁千(2.4-4.7mmol·L^-1)对西瓜幼苗细菌性果斑病的防效达到75%以上。In order to effectively control bacterial fruit blotch of watermelon seedlings,the test took watermelon seedlings as test materials,the effects of KCD3000 spraying at different concentrations on the incidence of bacterial fruit blotch of watermelon seedlings were studied.The results showed that with the increasing of concentration,control efficiency of KCD3000 to bacterial fruit blotch of watermelon seedlings increased gradually,but with too high concentration(above 9.4 mmol ·L - 1 ) caused drug damage to watermelon seedlings.The control efficiency of KCD3000(2.4-4.7 mmol ·L -1 ) with appropriate concentration on bacterial fruit blotch reached more than 75%.
