Spanish Catalonia sets leafhopper controls
The Spanish regional government of Catalonia’s plant health service has implemented a campaign to control leafhoppers in grapevines in the region. They cause the aggressive viral disease, grapevine flavescence, which “spreads quickly across grapevine areas”, the service says. The control programme includes insecticide treatments to take place from June to early August. A “collective campaign” has been waged since 1996 when the pest was first located in the region. The dates set for insecticide applications are determined by the insect’s life cycle and can vary from year to year, the service adds.
