Abstract
Maize is major staple food crop grown worldwide. In India, Maize is an important cereal crop next to rice, wheat and sorghum. Maize is known as Queen of cereals because of its high genetic yield potential. Maize is one of the largest consumable cereal in the world. It is not only an important human nutrient but also a basic element of animal feed and raw material for many industrial products. Maydis leaf blight is a serious foliar fungal disease causes considerable losses to the maize crop. The present investigation on “Efficacy of newer fungicides against Maydis leaf blight disease of maize caused by Helminthosporium maydis” were undertaken to work out the efficacy of fungicides under both laboratory and field condition for the management of Maydis leaf blight disease of maize. Fungicides were tested against H. maydis on the Potato dextrose agar media using Poisoned food technique given by Sharvelle (1961) under in vitro condition. Among all tested fungicides evaluated at different concentrations in vitro against H. maydis by Poisoned food technique, Propiconazole was found highly effective with cent per cent inhibition of mycelial growth of H. maydis at the concentrations (150, 200 and 250 ppm). Mancozeb showed 93.88 per cent inhibition at the concentration of 250 ppm at par with Propiconazole followed by Carbendazim (92.03 per cent at 250 ppm). Minimum inhibition of mycelial growth was recorded in Copper Oxychloride (57.41 per cent at 50 ppm). All fungicides screened under in vitro, were further evaluated under field condition against Maydis leaf blight disease. Propiconazole 25 EC @ 0.1% and Mancozeb 75%WP@0.2% were found most effective in reducing the Maydis leaf blight (PDI of 18.51% and 29.62% respectively), as compared to control (85.17% PDI).
