Abstract

Understanding the effect of environmental factors and sowing dates on disease development is crucial for optimizing crop health, improving yield, and devising effective, timely disease management strategies in agriculture. The current investigation, which was conducted During 2021 in the laboratory of the Department of Plant Pathology, Naini Agricultural Institute, and Sam Higginbottom University of Agriculture Technology and Sciences. To investigate the impact of environment and date of sowing on development of disease Maydis leaf blight of maize. During Kharif 2021 and 2022, for all four sowing dates, the disease progression of maydis leaf blight on maize variety CML-186 was monitored at weekly intervals beginning at 45 DAS of crop. It can be concluded that the crop stage showed the highest disease incidence at 45, 80, and 87 DAS; consequently, this stage tends to exhibit the most susceptible reaction during Kharif 2021. The crop stage with the highest disease incidence during Kharif 2022 was at 45, 52, and 80 DAS; as a result, this stage typically exhibits the most susceptible response. During Kharif 2021 and 2022, for all four sowing dates, the AUDPC of maydis leaf blight on maize variety CML-186 was noted at weekly intervals beginning at 45 DAS of crop.
