Abstract

Tomato is one of the most preferable and extensively grown vegetables in India as well as in Chhattisgarh. The tomato plant is infected with many diseases in its life but they do not occur simultaneously and their development varies with place and season. Therefore a study was undertaken in rabi season of three consecutive years (2014-15, 2015-16 and 2016-17) at Horticulture Instruction cum Research Farm, College of Agriculture, Raipur to know the prevalent diseases of tomato, their occurrence pattern and extent of infection. Five diseases viz. leaf curl, mosaic, tomato spotted wilt, early blight and collar rot were observed to infect the crop during the investigation. Under Raipur situations the first occurrence of leaf curl, collar rot, mosaic, early blight and tomato spotted wilt were recorded in November, December, December–January, January and January–February, respectively. Leaf curl and early blight were most serious diseases of the crop out of five commonly occurring diseases.
