Abstract:
The experiment was conducted Lal Bahadur Shastri Krishi Vigyan Kendra, Gopalgram, Gonda (U.P.) and laboratory, Department of Plant Pathology Mansarovar global university Sehore Bilkisganj (Madhya Pradesh) faculty of Agriculture Science and Technology in order to disease was seen on the leaves of some exotic varieties of Indian mustard grown in the Department of Plant Pathology's Agricultural Research Farm and on student trial plots inside the Faculty of Agriculture Science and Technology at Mansarovar Global University Sehore Bilkisganj (Madhya Pradesh). Five fungal toxicants, including mancozeb (0.2%), azoxystrobin (0.05%), propiconazole (0.05%), Pseudomonas, Trichoderma viride, and Trichoderma harzianum, were examined for their effectiveness as a seed therapy for Alternaria blight. during rabi 2020-2021 and 2021-2022 at the time of sowing under field conditions for two consecutive years. To make sure that foliage and blooming stage overlap with period of maximum disease development, susceptible mustard variety "NDR 8501" was sown during first week of November in both seasons. Based on results of the in-vivo study to evaluate the selected treatments, it may be concluded that among the botanical treatments, lantana leaf extract gave better results and among the chemical fungicides, Trichoderma viride @ 1ml /gm performed the best. In combined effect of the treatments also gave the satisfactory results to manage the Alternaria blight disease of mustard. Treatments gave the best result regarding yield and yield attributes.
