Evaluation of Phytoextracts Against Macrophomina phaseolina (Tassi) Goid Causing Root Rot of Greengram

Greengram was found to suffer from stem and root rot disease in severe form in Saurashtra region of Gujarat state during summer. The efficacy of various botanicals were evaluated against Macrophomina phaseolina (Tassi.) Goid causing root rot of greengram. The phytoextracts of nine plant species were evaluated in vitro by poisoned food technique against M. phaseolina. The extract of garlic cloves (Allium sativum L.) was proved excellent with maximum inhibiting (65.68%) mycelial growth and scanty sclerotial formation followed by turmeric extract (Zingiber officinale) (60.86%). while least growth inhibition (30.85%) was recorded in ardusi extract. Turmeric extracts were ineffective to inhibit the growth of the fungus at all concentration.
