Coryneum blight, a.k.a. 'shot hole disease', is a major problem of apricots, nectarines, etc. in coastal British Columbia due to the winter rains. People plant their
trees under the eaves of their houses to try to keep them as dry as possible, and I've even seen smaller trees planted under a pergola with a glass roof to keep the rain off. The only other alternative is apparently to use Bordeaux spray and extreme tree sanitation.
I'd like to have apricots but am wondering if there are alternative varieties that are less susceptible. I was thinking of planting some Manchurian apricot seed as it is a different species or subspecies from the standard commercial apricots. I've read that it is very drought-tolerant and cold-tolerant, which I was hoping also translated into disease-resistant. According to one web site I read, though, it is very susceptible to plum pox (whatever that is). So maybe the plant is not so tough after all.
Does anyone know how well it handles Coryneum blight, since that seems to be the major concern for growing it here?
