الوصف: | Bacteria from the genus Bacillus sp. have a high potential for the biological control of phytopathogenic fungi. Therefore, in the present research we proposed to evaluate the antagonistic capacity of Bacillus sp. isolates against the phytopathogenic fungus Sclerotium sp. The tests were performed using two methods (dual and modified dual), also using five Bacillus sp. isolates (LBM01, LBM02, LBM03, LBM04 and LBM06). Mycelial growth evaluations were performed on BDA culture medium. All experiments were performed in triplicate and the plates were incubated under a 12 h photoperiod at 28±1 ºC for 7 days. Radial growth of the pathogens was measured at the intervals of 24, 48, 72, 96, 120, 144 and 168 h. The percentage of inhibition was calculated using the equation: I% = [(C-T)/C]x100. All Bacillus sp. isolates tested were able to inhibit the mycelial growth of Sclerotium sp. within 72 h, while isolates LBM01, LBM03 and LBM06 were able to maintain inhibition for 168 h. The isolate LBM06 showed the highest percentage of inhibition in all two culture methods used. ; Las bacterias pertenecientes al género Bacillus sp. tienen un alto potencial para el control biológico de hongos fitopatógenos. Por lo tanto, en la presente investigación nos propusimos evaluar la capacidad antagónica de los aislados de Bacillus sp. contra el hongo fitopatógeno Sclerotium sp. Las pruebas se realizaron utilizando dos métodos (dual y dual modificado), así como cinco aislados de Bacillus sp. (LBM01, LBM02, LBM03, LBM04 y LBM06). Las evaluaciones del crecimiento micelial se realizaron en medio de cultivo BDA. Todos los experimentos se realizaron por triplicado y las placas se incubaron bajo un fotoperiodo de 12 h a 28±1 ºC durante 7 días. El crecimiento radial de los patógenos se midió a intervalos de 24, 48, 72, 96, 120, 144 y 168 horas. El porcentaje de inhibición se calculó mediante la ecuación: I% = [(C-T)/C]x100. Todos los aislados de Bacillus sp. probados fueron capaces de inhibir el crecimiento micelial de Sclerotium sp. en 72 h, ... |
