Investigations were made to determine the status of major targeted diseases of rice in different locations grown in agro climatic conditions of Jabalpur. With a view to determine the status of diseases in rice crop, survey was made in kymore plateau and satpura zone of Madhya Pradesh. Six different locations around Jabalpur (Panagar, Maharajpur, Patan road, Damoh road, Tilwara, Bhedaghat) and Seed production units at COA, Jabalpur were surveyed through random plot and fixed field survey method. Percent disease incidence was recorded on randomly selected 50 plants in a particular field of that location. In each village five randomly road side rice fields were selected. The incidence of diseases was observed on the basis of typical field symptoms and later the association was confirmed through microscopic examinations under lab condition. The incidence of sheath blight was higher in Panagar and Maharajpur. Least number of infected plants were observed in Maharajpur, Patan road, Damoh road and Tilwara. Grain discoloration was observed in range of 5.0 –17.0% at six locations. The incidence of neck blast was observed in one field of Damoh road and Bhedaghat in the range of 7.0- 10.0%.
