ABSTRACT: Foliar blight of wheat is mainly caused by Bipolaris sorokiniana (Sacc.) Shoem. syn. Drechslera sorokiniana (Sacc.) have emerged as serious concern for cultivation of wheat in warmer and humid regions of the world. A study has been conducted at Department of Mycology and plant pathology, Institute of Agricultural sciences, BHU, Varanasi  on  in vitro evaluation of direct effect of garlic cloves and  different botanical extracts  viz garlic (Allium sativum L.) clove extract, ginger (Zingeber officinale L.) rhizome extract, neem (Azadiracta indica L.) leaves extract, onion (Allium cepa L.) bulb extract, tulsi (Ocimum sanctum L.) and marigold (Tagetus erecta L.) leaves extract were evaluated against foliar blight of wheat. The reduction in growth of the fungus measured to the difference in radius of the colony covered with cloves and kept uncovered exhibited 45% reduction in growth of B. Sorokiniana four days after the clove treatment and out of the six test botanicals, garlic clove extract showed complete inhibition of spore germination  followed by ginger rhizome extract and neem leaves extract at the 5.0 percent concentration ( P=0.05).
