不同药剂对番茄灰霉病的防治效果研究

目的]为番茄灰霉病的防治工作提供参考。方法]试验设在安徽省合肥市三十岗乡，设6组处理，分别为：0350％速克灵可湿粉剂1500倍液；（至）25％灰克超微可湿粉剂10130倍液；③爱可2000倍液；（砚％扑海因悬浮剂1500倍液；⑤36％粉霉灵悬浮剂500倍液；⑥cK。观察6组处理对番茄灰霉病的防治效果，以及对番茄产量的影响。结果]除CK外，其余各组处理均对番茄灰霉病有不同程度的防治效果，以处理②、④的防效较好，分别为92．1％、85．4％，①、③、⑤的防治效果分别为：66．7％、79．4％、77．8％；与CK相比。各处理对番茄产量均有一定影响，其中，处理②的产量最高，达15941．30ks／hm2，其次为处理④，而处理①的产量最低，仅14162．63ks／hm2。结论]处理②、④是最佳防治药荆，且对番茄具有明显的增产作用。

Study on Control Effect of Different Medicament on Tomato Gray Mold

Objective] The study aimed to provide the reference for control work of tomato gray mold.Method] The test was conducted at Sanshigang County,Hefei City,Anhui Province,and divided into six groups,which including: ① 50% procymidone wettable powder;② 25% huikechaowei wettable powder 1 000 times liquid;③ aike 2 000 times liquid;④ 2% iprodione suspension concentrate 1 500 times liquid;⑤ 36% fenmeiling suspension concentrate 500 times liquid;CK.The control effects of six treatments on tomato gray mold and the influence on yield were studied.Result] The groups had control effect at different degree expect CK,the control effect of treatment ②,④ were better than the other,respectively for 92.1%,85.4%;the control effect of ①,③,⑤ were 66.7%,79.4%,77.8% respectively.All treatments have some influences on yield of tomato compared with CK,among them,treatment ② had the highest yield,which was 15 941.30 kg/hm2,then treatment ④,① which had the minimum yield(14 162.63 kg/hm2).Conclusion] Treatment ②,④ were the best control medicament,and had the obvious yield increasing effect.
