"Evaluation Of Specific Efficacy Of Fungicides, Bio Agents And Botanicals Against Leaf Spot Caused By Alternaria Alternata In Green Gram (Vigna Radiata L.): An Integrated Disease Management Approach”
Abstract
The present study investigated in the kharif 2022 and 2023 in RBD for check the efficacy of Different methods for managing leaf spot disease caused by Alternaria alternata.. Evaluated the impact of fungicides, bio agents and botanicals treatments at three distinct stages of crop growth: 30 days after sowing (DAS), 60 DAS and 90 DAS, providing a comprehensive understanding of their effectiveness over time. In research trails minimum percent disease incidence was recorded in treatment T4 - Foliar spray of T. viride @ 108 conidia/ml+Foliar spray with Neem oil @ 0.5%+ Foliar spray@ 0.1% Propiconazole 25% EC with pooled (kharif 2022 and 2023) 26.015, 33.55 and 45.00 at 30.60 and 90 DAS, respectively. Whereas treatment T4 - Foliar spray of T. viride @ 108 conidia/ml+Foliar spray with Neem oil @ 0.5%+ Foliar spray@ 0.1% Propiconazole 25% EC showed maximum seed yield 653.12 (kg/ha). The results highlight the importance of adopting a stage-specific approach to disease management, as the impact of Alternaria alternate and the effectiveness of treatments can vary significantly throughout the crop growth cycle. This research provides valuable insights into optimizing disease management strategies for A. alternata in Kharif crops, emphasizing the need for a holistic approach that integrates various control measures.
