Abstract:
Chilli (Capsicum annuum L.) is an economically important vegetable cum spice crop grown in almost all parts of tropical and subtropical regions of the world. Chilli leaf curl virus is one of the major limiting factors and is currently a serious problem in all the major chilli growing area of India. A survey was conducted during December- January months for two years (2018-19 and 2019-20), in five different districts of Chhattisgarh plains viz., Raipur, Durg, Rajnandgaon, Kabirdham and Dhamtari covering ten blocks viz., Tilda, Raipur, Kumhari, Kawardha, Pandariya, Lohara, Magarlod, Loharsi, Chhuikhadaan and Bodla, to record the percentage incidence of chilli leaf curl disease. Percentage incidence of chilli leaf curl in the year was 2018-19 ranged from 15 to 98% and was recorded highest at Raipur District (98%). In the second year, leaf curl incidence ranged from 14 to 100%, highest recorded at Rajnandgaon District. Commercial hybrids such as T-305, VNR 435, Pride, Sunidhi, Agnirekha, Namdhari 2722, Namdhari 2992, Armour, Karishma, VNR Vidya 725, Mahyco Sierra, Nupoor, Indu and Pusa Jwala, and other local cultivars were taken up by the farmers for chilli cultivation. A higher percentage of leaf curl incidence was recorded in the crop sown during October to November indicates the presence of viruliferous vector population might have favoured the higher incidence and spread of the disease.
