Abstract: In order to realize the technology of green prevention and control, the effect of new environmental-friendly microbial fungicide Yabijing against Aphis gossypii was explored, compared to two chemical pesticides (imidacloprid and chlorpyrifos). Field tests indicated that Yabijing, imidacloprid and chlorpyrifos showed high control efficacy. The control effect maintaine up to 98% after 5~15 days of microbial fungicide Yabijing application, and it had significant difference with the control effect of 10% imidacloprid and 40% chlorpyrifos application. The control effect of 10% imidacloprid and 40% chlorpyrifos application began to decrease and declined greatly after 15 days which resulted in increasing the quantity of A. gossypi.

Key words: microbial fungicide, chemical pesticides, Aphis gossypii Glover, control effect
