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. |
