Abstract: | Objective] To screen out reagents for controlling southern blight disease and soft rot disease of Amorphophallus albus.Method] We studied effects of five different reagents on field disease ratio and yield of Amorphophallus albus through plot test, and determined glucomannan content of Amorphophallus albus.Result] 600 times diluent of bronopol+300 mL/hm2 lunasen+800 times diluent of antracol had high yield of Amorphophallus albus,good control effect on southern blight disease and soft rot disease of Amorphophallus albus and high glucomannan content.Conclusion] 600 times diluent of bronopol+300 mL/hm2 lunasen+800 times diluent of antracol can be used to control southern blight disease and soft rot disease of Amorphophallus albus. |
