Cucumber viral jaundice, caused by the melon aphid, has spread rapidly in Dutch greenhouses due to limited pest control. The virus quickly yellows leaves and infects melons and gourds, making it difficult to control. The best strategy is to have zero tolerance for aphids in the greenhouse. Unfortunately, the ban on the insecticide Plenum has made this task more difficult for producers. Breeders play a crucial role in developing resistances to these viruses. In the meantime, growers are encouraged to ensure there are aphids causing the problem and to control them efficiently.
