Abstract
The comparative study revealed that mushrooms and botanicals extract were taken for screening the efficacy against pathogen Alternaria triticina in vitro through poisoned food technique. Maximum inhibition per cent was recorded on Lentinula edodes @ 2per cent (100%) as it was followed by Pluerotus florida (71.59%) @ 10 per cent and Azadirachata indica (67.25%) @10 per cent. The pot experiment was conducted for efficacy of best treatment against leaf blight disease of wheat. Ethanolic extracts of Lentinula edodes showed the less disease severity (14.41) in with greater wheat yield (90.89 gram) on average value. The average highest disease severity was recorded in control (68.67%) followed by methanolic extract of Pluerotus florida (64.33%) @10 per cent followed by methanolic extract of Allium sativum (63.15%) @10 per cent and Lawsonia inermis (62.05%) @10 per cent. Lentinula edodes was better fungicide for Alternaria triticina in comparison to all other treatments.
