When the snow melts very soon, go to the lawn & garden store and get dormant oil and spray according to directions for fall and then in the spring when the snow starts to melt spray the fruit tree again. We spray up to the bud stage........and after the bud open only spray the trunk of the tree up to the bottom branch. Wear old long clothes, goggles, mask, gloves and a hat. Do not spray if it' windy or going to rain. Keep children & pets away from that area until dry.
