摘要
[目的]筛选能够有效防治沿海地区保护地番茄早疫病的药剂。[方法]针对不同熟期的番茄品种通过田间试验研究了29％嘧菌酯·戊唑醇悬浮剂和44％百菌清·苯醚甲环唑悬浮剂对番茄早疫病的防治效果。[结果]按有效剂量计，29％嘧菌酯·戊唑醇悬浮剂130．5、174．0 g／hm2对早熟番茄品种早疫病的防效分别为75．40％和81．30％；44％百菌清·苯醚甲环唑悬浮剂660．0、825．0 g／hm2对中熟番茄品种早疫病的防效分别为74．60％和80．30％，可有效防治早熟和中熟番茄品种早疫病，且对番茄安全。[结论]试验结果为沿海地区设施番茄早疫病的防治提供了参考。
Abstract
Objective] The aim was to screen out fungicides for controlling tomato early blight under greenhouses in the coastal area .[ Meth-od] Control effects of 29% Azoxystrobin tebuconazole SC and 44%Chlorothalonil difenoconazole SC against tomato early blight of different ma-ture period were studied through field test.[Result] According to effective dose,the control effects of 130.5 and 174.0 g/hm2 29% Azoxys-trobin tebuconazole SC against tomato early blight of early-maturing variety were 75.40% and 81.30%;660.0 and 825.0 g/hm2 44%Chlo-rothalonil difenoconazole SC against tomato early blight of medium variety were 74.60% and 80.30%,and they showed good control effects on tomato early blight and were safe for tomato .[ Conclusion] The research results provide reference for the control of tomato early blight under greenhouses in the coastal area.
