Abstract:
Pearl millet (Pennisetum glaucum (L.) R. Br.) is one of versatile crop grown in arid and semi-arid regions of Africa and Asia. India is the single largest producer of pearl millet and subsistence for food, feed and fodder has been expanding into non-traditional regions of the world. Pearl millet encounter by several diseases during the crop growth, among them Pyricularia leaf spot, caused by Pyricularia grisea (teleomorph: Magnaporthe grisea) is one of the emerging threats to the production of pearl millet fodder and grain. In the current investigation, in vitro efficacy of three fungicides (Tebuconazole, carbendazim and propiconazole) at six different concentrations were examined against M. grisea. Out of which, fungicide propiconazole was found highly effective at 1500 ppm conc. with 100 per cent mycelium growth inhibition, whereas tebuconazole shows 90.74 per cent the mycelium growth inhibition. The maximum growth observed in case of carbendazim with the mean least mycelium growth inhibition (68.21%) against M. grisea.
