Title : Ecologically Sustainable Approaches for Mitigating Root Rot of Pea

Abstract :

The present investigation had been undertaken in the Department of Plant Pathology, College of Agriculture, CSK HPKV, Palampur during 2017-2019. The study identified Fusarium solani f. sp. pisi as the causative agent of pea root rot in the region. Pathogenicity tests revealed distinct symptoms, including blackening and maceration of roots, accompanied by leaf yellowing. Various disease management approaches were evaluated in vitro, with Vermicompost exhibiting the highest mycelial inhibition (36.7%) among composts. Trichoderma harzianum strain SMA-5 emerged as the most effective bioagent, displaying a 76.0% mycelial inhibition. Eupatorium adenophorum extracts showcased notable botanical efficacy (38.9% mycelial inhibition). Jeevamrit and Panchgavya proved potent among organic inputs, with Jeevamrit achieving complete mycelial inhibition at 8% concentration. For eco-friendly management module, soil amendment with Vermicompost @ 10 tonnes/ ha + chopped Eupatorium adenophorum leaves @ 20 tonnes/ ha and further seed treatment with Jeevamrit @ 5ml/ kg seed + Pseudomonas fluorescens @ 5ml/ kg seed + Trichoderma harzianum (SMA-5) @ 5g/ kg was found best against test pathogen with 60.87 % disease control.
