Abstract:
Sheath rot of rice caused by Sarocladium oryzae (Sawada) Gams and Hawksworth has become potentially destructive disease. A roving survey was carried out to know the severity of sheath rot in different locations of six districts in Northern Karnataka and two districts in Andhra Pradesh. Among the different places surveyed, high per cent incidence was recorded in Khanapur (35.59) and high PDI was noticed in Arabhavi (37.78). Among the eight districts, high per cent incidence (27.89) and PDI (22.42) was recorded in Dharwad. Among varieties grown in different districts maximum per cent incidence was observed in Sonamasuri (29.69). Among different sowing conditions drill sown paddy showed maximum disease incidence and PDI and the PDI was maximum in paddy grown in black soils.
