IPM program helps North Coast growers in fight against Virginia Creeper Leafhopper
Virginia creeper leafhopper (VCLH) first arrived in California's Sacramento Valley and Sierra Foothill regions in the 1980s.

In the absence of biological control, chemical controls for VCLH were required, needing to go on earlier in the season, in May or June. When the first outbreaks of VCLH occurred, many growers responded by putting on multiple late season sprays to little effect. Some certified organic growers resorted to conventional pesticides and lost their organic certification.
