  • The state's largest organization of wine grape growers is making signs for distribution to vintners who are concerned with the risks herbicide spray drift can pose to vineyards.
    Oregon Winegrowers Association is making fence post signs available to wineries and vineyard owners. The signs alert farmers who are using 2,4-Dichlorophenoxyacetic acid, commonly referred to as 2,4-D, to the potential danger to the state's 25,000 acres of vineyards.
    The systemic herbicide, used in the control of broadleaf weeds, is one of the most widely used herbicides in the world, and is the third most commonly used herbicide in North America.
    When it drifts beyond its target weed population, however, it can create a threat, specifically when it hits a pocket of cool air and falls on vines. Grapes are among the most sensitive of all plants to this chemical's ability to disrupt growth. In some instance, the herbicide can kill otherwise healthy, mature vines.
    The OWA is providing the 12- by 18-inch signs for $21 each through the OWA office in Portland. Grape growers can reach the OWA at 503-228-8336.
