The chili crop in Nagpur and Amravati [districts of Maharashtra] is
reported to have been hit by a virus. The infection may bring the
yield down by almost 50 per cent. Even growers in Madhya Pradesh have
been hit, where the crisis is reported to be worse [and] the crop
expected to be down to 30 per cent.
The state's agriculture department said there had been an attack of
the churda-murda virus. Around 50 000 hectares [about 124 000 acres]
area in Nagpur are under chili cultivation [and] growers [are]
reporting heavy losses.

[Chili leaf curl, locally known as 'murda', is the most destructive
disease of chili crops in India and Sri Lanka. The term is used
specifically in chili for disease symptoms including leaf distortion,
chlorosis, and necrosis, as well as stunting of plants and failure to
produce fruit. It is a disease complex which is thought to involve
feeding damage by chili thrips (_Scirtothrips dorsalis_) and broad
mite (_Polyphagotarsonemus latus_), as well as several viruses
including at least one whitefly transmitted leaf curl virus and
probably one or more _Tospovirus_ species. Secondary fungal or
bacterial infections via the feeding wounds may also occur. Disease
management relies mainly on systemic insecticides, and resistant chili
varieties are being developed.
