Hi I understand they have done some work on producing disease resistant grape vines, suitable for growing in the Pacific Northwest. Do you know where I can get information on these varieties ? Thanks Joe
Answer From Expert Roger Bohmrich MW
What type of disease resistance are you referring to in particular, as there has been a great deal of research and progress in this field in recent years. Much attention has been given to developing vines with resistance to Pierce's Disease. Advances have also been made in rootstocks with resistance to numerous pests (nematodes, for example). If you are a grape grower in the Northwest, I suggest you contact one of the universities in those states as well as the Berry & Grape Information Network (berrygrape.org) and the Washington organization of growers (wawgg.com).
