Evaluation of Antagonism of Penicillium TS67 Against Soybean Root Rot Disease and Corn Southern Leaf Blight

Abstract:

Through pot experiments, the disease index and control efficiency of TS67 cell, the fermentation liquid of TS67 and the supernatant of TS67 separately act on Fusarium oxysporum and Bipolaris maydis was detected. Experiment results analysis with SPSS statistical analysis software indicated all treatments of TS67 could inhibit both of soybean root rot disease and corn southern leaf blight (P<0.01). Using dressing seeding with the mixture of TS67 cell and Fusarium oxysporum on soybean, the maximum control efficiency of soybean root rot disease (63.98%) was obtained. Spraying the fermentation liquid of TS67 before infecting corn southern leaf blight, the maximum control efficiency of corn southern leaf blight (53.34%) was obtained. Furthermore, experiment results indicated that dressing seeding with TS67 on soybean promoted soybean seeding growth.
