Resumen

Botrytis cinerea es un patógeno fúngico necrotrófico de varias plantas distribuido en todo el mundo. En el presente estudio se analizó el efecto de nueve aislados bacterianos sobre la germinación de conidios de B. cinerea. Los aislados se identificaron como Bacillus amyloliquefaciens. Para evaluar la eficacia de los aislados, se realizaron confrontaciones duales tanto preventivas como simultáneas con los conidios de B. cinerea. Los resultados mostraron que cinco aislados fueron más eficaces cuando se co-inocularon simultáneamente con el patógeno. Cuatro aislados fueron más eficaces cuando se inocularon previamente cuatro horas antes el patógeno. La cepa denominada B24, mostró una inhibición de (84.04%) en concentraciones muy bajas (3x103 UFC/ml) y la cepa RA9 fue la cepa menos eficaz.
