This, as well as other shot-hole-producing fungi, maybe controlled by the use of neutral or alkaline dilute Bordeaux mix-ture, although the use of Bordeaux may be accompanied by in-juries to the foliage. Weather conditions seem to affect greatlyits relations to foliage injuries, and this is particularly true withrespect to the peach and Japanese plums. In any case, however, thorough spraying with strong Bordea
