Oxytetracycline as a preventative/treatment for Pierce's Disease?

gonebananas_gwMarch 10, 2014

I notice that oxytetracycline (an antibiotic) is able to be used on fruit trees as an injectable and thus systematic antibacterial agent. This includes for fireblight on pears and certain diseases of peaches and lethal yellowing of coconuts..

I wonder if it also might allow susceptible bunch grapes to be grown in the south?

I'm sure they would have tried it. Sure wish they would come up with a treatment as I would love to grow concords.

I have found a bunch grape growing semiwild in a long abandoned yard (now a thicket) where the house was torn down many years ago, this in central SC where bunch grapes routinely die in a few years. It looks a bit like "Concord," tastes a bit like it, and ripens irregularly in a bunch as "Concord" is reported to do in hot climates. It must be PD resistant. Could it possibly be a "Concord" bud mutation with some PD resistance?

In any case, it got accidentally trimmed along the edges of the yard where it grew best in sunshine (a parking lot abuts). so I cannot get dormant cuttings this season.
