Pyricularia oryzae is one of the most primary causes to destroy Rice crop in all the Rice producing countries. It causes Blast disease in Rice, other species of Pyricularia also infect the different monocot plant. Humidity, temperature, Rainfall and nutrients are the major factors which control the growth and spread of the Pyricularia oryzae. Some nutrients in very small quantities are required for the growth, development, and other physiological and metabolic activities of the fungi. In P. oryzae we can control the production of spores and growth by changing the quantity of these trace elements. In the present study, we tried to understand the effect of three trace elements or micronutrients i.e. Iron (Fe), Manganese (Mn), and Molybdenum (Mo) on spore formation and growth efficiency of P. oryzae.5 ppm (part per million) concentration of Fe is most suitable for optimum spore formation and growth in Pyriculariaoryzae when we increased the concentration of Fe in the media is poses a negative effect. Mn is required in a little more quantity than Fe. As we increased Mn concentration growth and sporulation increased respectively. On other hand, controlled quantity of Mo is sufficient for growth and sporulation. The increase in a small quantity of Mo in the medium poses a negative effect on Pyricularia oryzae growth and spore production. So, by manipulating quantities of these trace elements in the food chain, we can control blast disease.

The effect on seed germination, seedling growth, chlorophyll and protein syntheses were recorded. An inhibition of 35.4 to 42.6% in seed germination, maximum being in case of Samruddhi Gold was found. Seedling growth comprising root and shoot lengths also showed a marked reduction. An inhibition of 32.9, 40.8 and 37.4% in root length and 41.5, 46.5 and 46.3% in shoot length were recorded in Pusa Bold, Samruddhi Gold and J.K. Suraj, respectively. Visual chlorosis was observed in the emerging leaves of all the varieties. A depletion of 30.5 to 42.3% in total chlorophyll was recorded in the varieties. A significant inhibition in protein biosynthesis was also noted. It was 15.9% in Pusa Bold, 22.8% in Samruddhi Gold and 26.8% in J.K. Suraj.
