Effect of Micronutrients and Fungicides on Spot Blotch of Wheat

Experiment was conducted to know the effect of deficient and recommended doses of micronutrients (Zinc, Iron, Manganese, Boron, Molybdenum and Sulpher) and fungicides (Carbendazim and Mancozeb) on incidence and severity of spot blotch disease and crop yield. Efficiency of micronutrients and fungicides was tested by spraying at tillering and boot leaf stages. During both crop season i.e. 2008-09 & 2009-10 minimum disease incidence was observed which was double when sprayed with Carbendazim followed by two times application of Mancozeb. Among micronutrients, application of molybdenum, boron and manganese resulted in minimum disease incidence when applied at tillering and boot leaf stages. In case of fungicides severity, Carbendazim resulted in maximum reduction of spot blotch incidence, severity and gave highest yield followed by Mancozeb in the order of superiority mentioned.
