In Vitro and in Vivo Efficacy of Fungicides against Alternaria triticina Causing Leaf Blight of Wheat

Leaf blight of wheat caused by Alternaria triticina is a major constraint in production of wheat. Management of diseases using fungicides is a common and economical practice. Different types of chemical fungicides are available to control leaf blight disease. But there is a lack of awareness regarding the use of suitable fungicides on wheat plants affected with Alternaria triticina. The experiment was conducted under in vitro conditions to observe the effect of fungicides like Propiconazole (25%EC), Mancozeb (75WP) and Carbendazim (50% WP) against Alternaria triticina by Poisoned Food Technique. Propiconazole showed the highest range of (94.93%) inhibition followed by Carbendazim (90.85%) and Mancozeb (90.65%). The research findings in the present study suggest Propiconazole (25EC) as most effective fungicide for the treatment of leaf blight disease of wheat. Propiconozole 25% EC was found to be the best among all treatments for inhibiting the growth of mycelium of Alternaria triticina under in vitro condition. Propiconozole 25EC @ 0.1% was the superior spray solution in comparison to all fungicide for controlling leaf blight disease of wheat.
