Evaluation on potentiality of bio-agents against Drechslera oryzae causing brown leaf spot of Paddy

The potentiality of bio-agents viz. Trichoderma harzianum (Delhi), T. hazianum (Kanpur), T. viride (Delhi), T. viride (Kanpur). G. virens (K), T. hamatium (K) against Drechslera oryzae inhibited the growth of Drechslera oryzae. Maximum reduction (98.8%) was recorded in T. harzianum (Delhi) isolate f...

Summary:The potentiality of bio-agents viz. Trichoderma harzianum (Delhi), T. hazianum (Kanpur), T. viride (Delhi), T. viride (Kanpur). G. virens (K), T. hamatium (K) against Drechslera oryzae inhibited the growth of Drechslera oryzae. Maximum reduction (98.8%) was recorded in T. harzianum (Delhi) isolate followed by T. harzianum (Kanpur) (94.6%). Treatment of rice seeds with spore suspension of T. harzianum (Delhi) proved significantly superior in enhancing the maximum shoot length and root length at 30 days of seedlings. The foliar spray with crude extract of bio-agents were competence enough to reduce the number of lesion from 13.49 to 3.15. Disease severity was varied significantly from 14.1 _ 58.1% in different treatments.
