Control biológico de Colletotrichum fusarioides O´Gara, patógeno de semillas de albahaca (Ocimum basilicum L.) con Trichoderma Rifai


The effectiveness of Trichoderma isolate for the biological control of Colletotrichum fusarioides was studied.Trials were performed in the greenhouse by sowing pre-treated basil seeds with a bioproduct (liquid and semi liquid) of Trichoderma + C. fusarioides. The antagonistic effect was evaluated through: number of germinated seeds and healthy plants. Statistically significant differences (p<0.05) were observed in relation to: increase of germination rate (69% liquid multiplication), seeds treated with Trichoderma + C. fusarioides and a higher number of healthy plants (84% liquid, 26% semi liquid) obtained from seeds inoculated with the antagonist + pathogen compared to those only inoculated with C. fusarioides.
