BIO-CONTROL OF LATE BLIGHT OF POTATO

In the present study, four bio-agents, viz., Penicillium aurantiogriseum, P. viridicatum, Trichoderma viride and Acremonium strictum were evaluated for their potential in controlling potato late blight. All the four bio-agents significantly reduced P. infestans sporangial germination, T. viride and' P. viridicatum being better than the others. Besides, all the bio-agents tested provided good control of late blight development both on detached leaves and whole plants of potato cv. Kufri Chandramukhi.
