Studies on Antimicrobial Effect of Botanicals on Leaf Blight of Indian mustard Caused By Alternaria brassicae

The present study was conducted at ANDU&T Kumarganj Ayodhya at student instructional form (SIF). As in the investigation it was observed that foliar spray with Carbendazim (0.1%), Neem oil (5%), followed by Neem leaf extract (5%) found to be more effective on growth parameters like Number of branches/plants, number of leaves/ plants, plant height (cm), number of pods/plants,) and increased the yield (1000-seed weight, per plant yield (g), per hectare yield) and also significantly reduced the Alternaria blight in Indian mustard. Carbendazim (0.1%), Trichoderma harzianum (2%) followed by garlic bulb extract (5%) was found most effective in reducing Alternaria blight, recorded maximum disease incidence i.e. percent Disease intensity, percent Leaf area disease (LAD), percent leaf infection, number of spots per pods, seed infection percent respectively.
