Abstract:

Chilli crop is attacked by a large number of pathogens but heavy crop loss is caused due to leaf curl disease of chilli caused by Begomovirus belonging to the family Geminiviridae is transmitted by viruliferous whitefly (Bemisiatabaci Genn.). In India, Senanayake et al., (2006) have reported first time chilli leaf curl virus on chilli crop and crop loss has been estimated up to 80% in some parts of India (Nigam et al., 2015). Therefore, an integrated approach involving physical, botanical and chemical module has been formulated to manage the chilli leaf curl virus disease during three consecutive years from 2014-15, 2015-16 and 2016-17 at AICRP on Vegetable Crops, OUAT, Bhubaneswar during Rabi season. Our results showed that the chilli leaf curl virus disease could effectively be reduced by all the treatments through integration of physical, botanical and chemical management practices since they were statistically equally effective over control in respect of reducing disease incidence and white fly population/plant and fruit yield (q/ha). But while considering cost of different treatments and net income over the years, the pooled data revealed that the maximum net return (Rs.1,36,909/-) was obtained with integrated management practices (T3) with substantially low percent disease incidence (6.9%) and white fly population/plant (0.99/plant) while minimum net return was recorded in T6 (Rs.25,261/-). Similarly, the cost benefit ratio was found to be the maximum in integrated management practices (T3) (2.44) and the minimum B: C was recorded in T6 (1.29). So, chilli growers who are facing problem from chilli leaf curl disease can easily grow their crop by adopting the technologies involving spray of Imidacloprid 70% WG @ 2 g/15 l + Neem oil @ 2 ml/l at 7 days interval till fruit formation coupled with border crop of maize (Two rows of maize at 15 days prior transplanting) and use of Agri silver mulch because this integrated disease management practice (T3) gave maximum net return (Rs.1,36,909/-) with highest B:C ratio (2.44).
