Abstract
Chilli (Capsicum annuum L.) is one of the most important
constituent of the cuisines of tropical and subtropical countries and the
fourth major spice as well as commercial vegetable crop cultivated globally.
Among the various biotic stresses chilli leaf curl virus (ChiLCV) is the major
virus disease in the chilli cultivation. Due to the availability of inoculum
from the alternate host, vector population (whitefly), congenial environmental
conditions and monocropping of chilli the ChiLCVD has been spreading continuously
and causing >98 per cent of yield loss as per the earlier reports.
Information of its distribution, host cultivars and vector abundance helps in
determining its management. In the present study, survey to know the status of
ChiLCVD across six districts of North Karnataka was carried our during Kharif
2024-25. Among the six district surveyed, disease incidence ranging from
12.45 to 54.52 per cent and highest average district disease incidence was
noticed in Raichur (48.35 %) and minimum in Haveri (12.45 %). Irrespective of
soil types the ChiLCV infection was found in all the cultivars. This
information helps to identify the ChiLCV and vector free areas for successful
chilli cultivation
