ABSTRACT

ABSTRACT 

Chilli is the foremost important spice crop of India. It is affected by many diseases, among which chilli fruit rot is a major fungal disease that causes severe yield loss. A rowing survey was conducted in different places of Tamil Nadu. The overall disease severity ranges from 19 per cent to 3.6 per cent. The highest fruit rot disease incidence was recorded in Kovilpatti and the least was recorded in Sathanoor. The pathogenicity of these isolates through different inoculation methods on unfascinated semi ripe chilli fruit variety K1 revealed that C. capsici Ccl17 was most virulent with an average lesion size of 16.5 mm and a least lesion size observed in Ccl3 was 4.9 mm. Among the twenty isolates, the isolate Ccl17 was significantly the most virulent one, which recorded the highest fruit rot intensity (65.8 %) and leaf infection (59.7 %) followed by CcI19 which was the least virulent. In the present study, an exhaustive survey was conducted in Tamil Nadu during 2019 to know the incidence and severity of the fruit rot disease in a large scale basis

Keywords: Colletotrichum capsici, pathogenicity, virulence, chilli
