Abstract:
A survey for occurrence and distribution of rice sheath blight disease was conducted in major paddy growing areas of Andhra Pradesh during Kharif 2019.-20. Farmers’ fields were selected at random in different mandals of West Godavari, East Godavari, Nellore, Y.S.R. Kadapa and Chittoor districts. The per cent disease incidence (PDI) ranged from 11.31 to 45.66 per cent. Maximum PDI (45.66) was recorded at Penumanchili village of West Godavari district, while minimum (11.31) was observed at Koppolu village of Y.S.R. Kadapa district. The disease was observed from maximum tillering stage to grain hardening stage.
