Leafroll Receives Designation as a Threat To Winegrapes
The PD/GWSS Board has designated grapevine leafroll disease as a serious threat to California winegrapes. The disease and its vectors are now eligible for Board funding for research and outreach.
Since 2010, the Board has had the ability to use assessment funds for research and outreach on other serious pests and diseases of California winegrapes, as long as such funding does not substantially diminish PD/GWSS research and management efforts.
In 2014, the Board designated grapevine red blotch-associated virus (GRBaV), vine mealybug, and the brown marmorated stink bug as serious pests and disease of California winegrapes, making them eligible for funding research and outreach activities.
