This table summarizes the reactions of nematodes likely to cause problems on stonefruits and nuts in California to four popular rootstocks.
In order to select a suitable rootstock, one needs to know which nematodes are present.
Nemaguard is sold as a "resistant" rootstock, often without specifying to which nematodes it is resistant. If root-knot nematode is the problem, Nemaguard as well as several rootstocks are good candidates.
However, for ring, lesion or dagger nematode, all rootstocks (including Nemaguard) are susceptible and intolerant.
Research by H. Ferris and M. V. McKenry indicates that in a ring nematode infested orchard, nematode damage will be more severe on Nemaguard than on Lovell rootstock.
Often, other factors (which are beyond the scope of this discussion) than nematodes (e.g. soil type and plant pathogenic fungi) need to be taken into account when choosing a rootstock.
Within California, University of California Farm Advisors should be consulted when choosing a rootstock.
