Abstract:
The presence and environmental condition is very important factor on agricultural production especially manage rice growth. The culture from the National Research Centre for banana, Tiruchirappalli was sub cultured and inoculated in the soil. The present experiment was conducted for isolation and inoculation of endophytic fungus, Beauveria bassiana in soil as well as in rice seedlings by differential application methods to ensure the availability of this fungus in the plant system. Experiment conducted for whether this fungus is in available in the plants system and also causing the impacts on the Cnaphalocrocis medinalis larva in rice. The source of leaf folder was collected from the field near by the Anbil Dharmalingam Agricultural College & Research Institute, Tiruchirappalli. The rice leaf folder making their incidents in all seasons of rice period in all over the world. The pathogenicity of B. bassiana tested against by using the 2 x 106 ratio of conidial suspension. The bio assay con ducted in pot culture revealed this fungus giving the mortality against the leaf folder in all the treatments. Even though the foliar spray, root dip method and seed treatment having the high mortality after the ten days inoculation in the plants as well as eco-friendly to the environment. Hence, endophytic B. bassiana present in the rice plants can be largely exploited for the controlling of rice leaf folder in eco-friendly manner.
