Journal of Nutrition and Food Sciences. PAPAYA LEAF CURL DISEASE (Papaya leaf curl virus.) Main symptoms of papaya leaf curl disease are inward/outward curling of plant leaves, vein thickening, and stunted plant growth with small distorted fruits or no fruits. Raven press, New York, p 364, Flint ML (2015) Integrated pest management for homes, gardens, and landscapes. However, holding the population of whiteflies in check can reduce the severity of the infection.

Sci Rep 6:34706. Symptoms of papaya leaf curl disease appeared in the form of severe distortion of leaves associated with curling and rolling of leaves, leathery leaf, vein zigzag and reduction in the size of petioles, internodes, and main shoot. 6.

Mol Plant Pathol 8:223–231. To help assess the risks of spread of this virus, we compared the acquisition, retention and transmission of PaLCuCNV among four species of whiteflies, Middle East-Asia Minor 1 (MEAM1), Mediterranean (MED), Asia 1 and Asia II 7.

It is mainly transmitted by whiteflies. Not logged in Papaya leaf curl virus is not transmitted through mechanical work in the field. The virus is widely distributed but as of today it has a limited incidence. Virology 204:289–296. At later stages of the disease defoliation can occur.

Papaya, Carica papaya, is an herbaceous perennial in the family Caricaceae grown for its edible fruit. Soil application at the time of sowing and 4-5 foliar sprays of dimethoate or metasystox at an interval of 10 days can effectively control whitefly populations.

Labeled leaf curl of papaya diagram. Top leaves are most affected. Papaya leaf curl China virus (PaLCuCNV) is a distinct begomovirus found in Guangxi province of China (Wang et al., 2004).In recent years the virus has caused a severe leaf curl disease on papaya in southern China. Whereas, maximum leaf curl disease incidence (23.50%), during 2007-08, was recorded in Lucknow district. doi: Sagar SB, Parmar HC, Darji VB (2012) Economics of production of papaya in middle Gujarat region of Gujarat, India.
