Q.How does the sunblotch affect the root stock
If i can graft the infected cultivar bud wood on the negative root stock will then discover later that my bud wood was infected then i cut off the grafting union. Does that mean the root stock is also infected?

The disease is usually transmitted during the grafting process. When any signs of the disease develop, the tree should be removed to prevent further infection of other trees. Avocado plants are highly susceptible.
