Abstract

ABSTRACT: Early blight disease is painful nerve to tomato growing farmer because it causes huge economic loss to the farmer every year. Alternaria solani cause early blight of tomato and it is considered weed of field because of its wide adaptability under different environment. Use of fungicides for the management of disease in crop puts a large number of negative health and environmental effects therefore, the urgent need for a more sustainable and ecological approach to manage disease without fungicides. To avoid relying solely on chemicals and to identify a viable alternative component, five neem formulations and four bio-inoculants were evaluated by Poison Food Technique and Dual Culture Technique in the lab in the year of 2020-21 against A. solani. Among neem formulations, neem oil (71.91%) was found effective inhibiting mycelial growth of A. solani followed by multineem (58.49%), Neem excel (48.92%) and Repellent plus (38.00%) at the mean of two concentration (1000 & 1500 ppm).
