TL;DR: Several fungicides, antibiotics, oils and oil cake extracts were tested for their effectiveness against sugarcane downy mildew of maize caused by Sclerospora sacchari and a combination of chloroneb seed treatment, rogueing of infected plants and one foliar spray of azadirachta oil gave the most effective control.
Abstract: Several fungicides, antibiotics, oils and oil cake extracts were tested for their effectiveness against sugarcane downy mildew of maize caused by Sclerospora sacchari. In the laboratory eight fungicides, three oils and two oil cake extracts significantly inhibited conidial germination. In the field seed treatments with chloroneb, toluene-p-sulphonamide and sodium lauryl sulphate significantly reduced disease incidence. Furrow treatment with chloroneb gave better results than the seed treatment. In the glasshouse azadirachta and maduca oils and extracts of their cakes gave promising results. A combination of chloroneb seed treatment, rogueing of infected plants and one foliar spray of azadirachta oil gave the most effective control.
