Quick scan for cotton leaf curl Gezira virus

Description

This Quick scan was prompted by repeated findings of CLCuGV in cultivars of Lavatera/Malva (Malva is currently the preferred name but many plants are still traded as Lavatera). 

CLCuGV is a begomovirus and all but seven begomoviruses are regulated as Union quarantine pests. 

CLCuGV is officially absent from the EU, but the virus is most likely present in ornamental plants of Lavatera/Malva in the EU. 

Economic impact can be expected if CLCuGV were to become established in areas where susceptible host plants, especially cotton or okra, are grown and the natural vector B. tabaci is present. However, there is a high uncertainty whether the isolates found in the Lavatera/Malva cultivars can be transmitted by B. tabaci and if this is the case, whether these isolates can be transmitted to other plant species.
