Greenhouse and field tests carried on for four years have shown that the Loganberry is not affected by Verticillium wilt, the most serious disease of the Boysen and Young varieties. The Logan therefore can be grown on land cropped previously to tomatoes, potatoes or other susceptible crops without danger of wilt losses, and can even be intercropped the first year with tomatoes. The Loganberry is also immune to powdery mildew, a serious disease of the Boysen and Young varieties in the coastal berry growing districts of California.
