Abstract

Fusarium oxysporum and Rhizoctonia solani are causal agents of chili wilt and cause losses up to 80% in the crop in Mexico. The inadequate use of chemical fungicides has generated problems of resistance, this was not observed with microbial agents, so they were evaluated in the biocontrol of wilt of chili in experimental plots where F. oxysporum and R. solani were identified as causal agents of the illness. Trichoderma spp., Bacillus spp., mixture of microbial propagative ferment, thiabendazole and control, were applied on a plot of 800 m2 with six varieties of chili. The treatments Trichoderma and propative ferment showed low percentages of incidence and severity, high yield with Trichoderma in HS-52 and Coloso (15.67 and 13.89 t ha-1). Trichoderma treatments and propagative fermentation promote the biocontrol of chili wilt caused by F. oxysporum and R. solani and increase yield.
