Abstract
Background
Maize Downy Mildew (MDM) is a devastating disease in the humid sub-tropical/tropical regions of Asia. In this study, the prevalence of MDM during the rainy Kharif seasons of south Karnataka state (India) ranged between 6.8% (2018) and 19.1% (2022). The research evaluated new fungicidal treatments and assessed the genetic tolerance of maize lines to develop robust management strategies that enhance maize productivity and stability.
Results
During the Kharif seasons of 2021 and 2022, we conducted field trials to evaluate the effectiveness of six different fungicides, both individually and in combination. The most effective approach combined seed treatment with Metalaxyl (4%) and Mancozeb (64%) WP, followed by a foliar spray of Azoxystrobin (18.2%) and Difenoconazole (11.4%) SC. This treatment reduced MDM incidence by 97.6% and increased maize yield up to 85.6 quintals per hectare, with a benefit-cost ratio of 2.2. Additionally, screening of 317 maize inbred lines in Kharif
