| Hoping folks can give me some recommendations on some table grape varieties that are either naturally resistant to Pierce's Disease, or have been bred to be resistant to Pierce's Disease (Xylella fastidiosa). Due to my proximity to an 80 acre abandoned orange orchard, most of my oleanders are exhibiting signs of Oleander Leaf Scorch. Plus, I appear to have 3 or 4 grape vines that are having great difficulties growing (when I first moved into our home last September, I didn't even realize they were there, they are stuggling so badly). They struggle in the summer to produce maybe 4 or 5 leaves, that end up turning brown and crispy, so I'm assuming I probably also have Pierce's Disease as well, sigh... I am in Vista, which is in N. San Diego County, about 7 miles from the ocean, and the grapes would be planted on a hillside, possibly up against my wrought iron fencing, getting just about full sun all day, and a southern exposure, so nice and warm. I know that some of the native California grapes as well as muscadines tend to be more resistant, but I sure love good tasting table grapes. And possibilities of finding something that is being bred to be resistant to X. fastidiosa? And, where I might purchase these? That would be just fabulous!!

| Most labrusca grapes (think concord) are resistant to Pierce's. As stated before, Jupiter (Raintree Nursery) is a top seedless grape with excellent disease resistance. Maybe you could dig up specific info on Jupiter's Pierce resistance on the University of Arkansas web site as the developed it. Other favorite labrusca table grapes of mine are Suffolk Red, Glenora, and Steuben. |

| Thanks, fruithack. Unfortunately, Jupiter is not resistent to Pierce's Disease, as are any of the Arkansas local grape varieties/hybrids. Here is a quote right from U of Arkansas' website about their local varieties, which includes Jupiter: "...Although developed in the South, the Arkansas varieties are not resistant to the most devastating grape disease in the deep South - Pierce's disease. These varieties are not recommended where Pierce's disease is a threat." Labruscas are not naturally resistent to Pierce's, but do have some better than normal resistence to fungal infections. Which is too bad, because I LOVE Stubens, yum. I think you might be thinking of the muscadines (native N. Carolina grapes)? They DO have a natural resistence to Pierce's, although not entirely immune, and I'm probably going to end up with a couple of muscadines (Late Fry and Darlene), since I can't find any California table grapes that are either resistent or immune. U of Florida has done some extensive research, and I just happened upon a great article written about their PD-resistent grapes they are recommending to both commercial growers as well as hobbists: So, I'm going to check into Blue Lake, Conquistador, Stover, Suwannee and Daytona as options as well. I understand muscadines can be an "acquired taste", and I have never had a chance to try them, so I might just toss the dice and put up the muscadines, too. :-) Patty S. |

| Patty- Try find an America grape, they're pretty tough plants. Seems like I've seen them available to ship to CA. I still say try a Jupiter and Steuben. Maybe your micro-climate in combo with them will work out. I've made a career out of ignoring the "experts" (if you only knew). About half the time I come out smelling like a rose, about half the time I get hammered. Good luck. |

| Your dilemna is understood. PD nearly wiped out Orfila winery. Check out Blanc du Bois as offered by Willis Orchards. The company is able to ship to CA, which is an important part in your quest. |

| In doing some pretty extensive research, I found that the Unversity of Texas in conjunction with the Texas AgriLife Extension Service have been working with Martha and Friench Tarkington, owners of Tarkington's Vineyard in Victoria, Texas. They have developed a new grape variety that has been tested in Texas as well as in Arkansas, working with the University of Arkansas. I think this testing has spanned about 20 years in total, looking back at this variety retrospectively at the Tarkington's vineyards where its been growing for that amount of time. It is officially called 'Victoria Red' and is an extremely large table grape that will be available to the public in 2011. The Texas Extension office is offering up a limited supply this spring to those who requested a small number of vines. I was able to get on the list, and I should be getting 2 vines in about 4 weeks or so. Here is a link about this really incredible table grape, which has defied PD in both Texas and in trials for U of Ark. Patty S. |

| I too have been wanting to grow bunch grapes, wine or table, for a while. Got a white grape vine that has fruited in a container, but it will presumably succumb at some point. More recently, I was looking again, and found there are a number of varieties out there, mostly wine grapes, but they should be good for eating too. Most, if not all are seeded, but I'm giving some a try. There are a few places I found to get them, but Willis Orchards doesn't have the best reputation, and Macevicius Farms is sold out right now. However, Truevine Vinyards has 4 varieties, including the Blanc du Bois mentioned above, so I ordered 4 of each, and was very happy with what arrived. Truevine don't have online ordering, but on the strength of an email exchange, Chris sent the vines followed by an invoice, with payment to be made by check. |

| Thanks, Joseph. Great information. University of Texas and Texas A&M have done some very intensive research on PD resistant grapes, especially table grapes and their info is really helpful for those of us in PD areas. If I could get the grapevines in my yard to grow more than just a few leaves, I could tell for sure what's ailing them. But since they turn brown and die before I can get a good look, odds are very high it's PD. So, Going with Victoria Red, which at this point, appears to be IMMUNE to PD, and would be my best choice. I could try Orlando Seedless if I can find some more room in my yard, since Victoria Red is seeded, so definitely going on the "list". Patty S. |
