Management of Fusarium wilt of lentil using antagonistic microorganisms in Tarai region of Uttarakhand

Ankita Garkoti, H. S. Tripathi

Abstract

Two bio-agents, Trichoderma harzianum and Pseudomonas fluorescence were screened in vitro against Fusarium wilt pathogen of lentil by using dual culture technique. Observations revealed that T. harzianum grew faster than P. fluorescens. All the isolates of T. harzianum significantly checked the growth of the test pathogen. Maximum inhibition (71.8%) after 96 hrs of incubation was recorded with isolate of Th 5 followed by Th 39 (70.8%) and Th 14 (68.9%). Isolates of P. fluorescence were found less effective in comparison to T. harzianum in inhibiting the growth ofthe test pathogen (Fusarium oxysporum f.sp.lentis).
