In any IPM program, the use of resistant cultivars is an important consideration. Many commercial cultivars have resistance and/ore tolerance to leaf spot, leaf scorch, red stele, and powdery mildew. The more resistance within a program, the better. Table 21 (page 27) lists ratings for disease resistance in several of the more commonly grown strawberry cultivars.
