Evaluation of efficacy of chemicals against zonate leaf pot of sorghum
Author(s): Mamta and Y Singh
Abstract: Zonate leaf spot caused by Gloeocercospora sorghi Bain & Edgerton is one of the most destructive diseases of sorghum in India and Uttarakhand is considered as a hot spot for this disease. The present investigation was carried out to test the efficacy of eight chemicals viz, Mancozeb, Carbendazim, Blitox-50, Roko, Sure, Tilt, Ridomil and Kavach were evaluated at different concentrations (50, 100 and 250ppm) against G. sorghi for their antifungal activity in-vitro condition. At minimum concentration i.e. 50ppm, Mancozeb gave maximum mycelial growth inhibition (100%) of the test fungus followed by Carbendazim (97.13%), Ridomil (97.02%), Tilt (95.80%), Kavach (94.65%) and Sure (94.13%). At 100 and 250ppm, Mancozeb, Carbendazim and Ridomil showed complete inhibition of test fungus. The findings suggest that Mancozeb and Carbendazim can suppress the pathogen.
