tailieunhanh - Evaluation of the efficacy of culture filtrate of Trichoderma isolates against Colletotrichum graminicola causing anthracnose of sorghum

In the present study, the efficiency of 15 day old culture filtrate (nonvolatile compound) of 20 Trichoderma isolates was evaluated at 10% and 25% concentration using poison food technique against mycelial growth C. graminicola. All the 19 isolates of Trichoderma asperellum and one isolate of Trichoderma harzianum were significantly reduced the mycelia growth of C. graminicola over control at 10% and 25% concentration. The maximum reduction of mycelia growth of C. graminicola at 10% and 25% of T4 isolate which recorded and inhibition radial growth respectively. | Evaluation of the efficacy of culture filtrate of Trichoderma isolates against Colletotrichum graminicola causing anthracnose of sorghum
