They show a mortality of 70 –80 per cent if forced to feed continuously on papaya for more than 24 hrs. Whitefly management is the main method to control the spread of this virus so far. Papaya leaf curl disease was first reported in India in 1939 (1). The main symptoms are downward and inward rolling of top leaves and thickening of veins. Other symptoms include the thickening of the leaf veins, sometimes with the formation of outgrowths. The leaves become leathery, brittle and distorted. p. 126. 2009-01-20 13:25:43 2009-01-20 13:25:43. doi: Rudolph C, Schreier PH, Uhrig JF (2003) Peptide-mediated broad spectrum plant resistance to tospoviruses.
