Cucurbit Yellow Stunting Disorder Virus (CYSDV)
This virus is transmitted by the white fly. This virus causes severe yellowing of the leaves and is moved in symptom less watermelon transplants.
Cultural Control
Destroying infected cucurbit plants and removing overwintering crops early in the spring prior to the emergence of adult white flies may prove useful. To be effective, this sort of control measure should be applied over an entire area and preferably where there is no continuous production in glasshouses, as these are often the sites of white fly activity and active virus spread throughout the year. Weeds in and surrounding glasshouses should also be destroyed as they could act as hosts for B. tabaci.
