Eco Friendly Management of Fusarium Wilt of Chickpea with Botanicals and Bio Agents in In-vitro

Abstract

Chickpea (Cicer arietinum L.) is one of the most important pulse crop grown all over India. Chickpea wilt caused by Fusarium oxysporum f. sp. ciceri is one of the major disease on chickpea in Northern Karnataka, which is soil and seed borne. Heavy inoculum in the soil and favorable environment condition results in the death of infected plant and therefore total yield loss.In this study, three antagonists, and seven botanicals were studied against Fusarium oxysporum f. sp. ciceri causing chickpea wilt. In vitro studies found that among the botanicals, turmeric rhizome extract gave maximum per cent inhibition of mycelial growth (26.73%) and least per cent inhibition of mycelial growth (9.96%) was observed in cassia tora at 15 per cent concentration. Among the antagonists, Trichoderma harzianum was effective in per cent inhibition of Fusarium oxysporum f. sp. ciceri with (76.47%) and Pseudomonas fluorescens found least effective in per cent mycelial inhibition with (34.41%).
