Also the diseased plants do not die quickly, never recover, and if allowed to stand in the field they help spread of disease to healthy plants. Epidemiology. Peach leaf curl reduces the amount of leaves and fruit produced by peach and nectarine trees. Diseased plants produced small and distorted fruits that tend to fall prematurely.

These results suggest that the causal agent of papaya leaf curl disease is a bipartite geminivirus that may be provisionally called papaya leaf curl virus (PLCV).

This virus is a serious threat to Australia’s cotton industry. Papaya trees are tropical plants that produce pear-shaped and melon-like fruit. The viral disease caused by Papaya leaf curl virus (PLCV) has become a serious loss to pawpaw cultivation in Northern India. Severely affected plants produce fewer, smaller, and deformed fruits. Several diagnostic techniques especially molecular techniques have been developed to detect the begomoviruses at early stages of infection to control the further spread of the begomovirus, but so far not much reports are available to control the begomoviral infection at later stage. It is not seed or soil borne nor sap transmissible but is transmitted by grafting and white flies. PaLCuV is found in tropical and subtropical regions, and it significantly affects papaya production in India's major papaya growing regions. Not affiliated (Penz.
