ABSTRACT
The present investigation emphasizes the role of rice ear head bug and mealy bug in predisposing the rice plant for sheath rot (Sarocladium oryzae) infection was established by the present study. Infestation of rice earhead bug (10/tiller) followed by the spraying of the spore suspension of sheath rot fungus recorded the maximum (584.00) sheath rot disease index. The disease incidence increased with increase in earhead bug population. The maximum (674.67) disease index was recorded in the plants inoculated with 10 mealy bug crawlers soaked in spore suspension/tiller which was significantly different.
Key words :
Disease index, Rice, Sheath rot, Sarocladium oryzae.
