Non-Chemical Management
- Plant disease-resistant cultivars such as 'Antonovka', 'Delicious', and 'Wealthy'. 'Golden Delicious', 'McIntosh', and 'Rome Beauty' are moderately resistant.
- The rootstocks M9 (highly resistant) and M2, M7, M26, and MM111 (moderately resistant) resist crown and collar rot.
- Do not overwater or allow water to pool at base of trees.
- Avoid wounding crowns and collars.
- Cut out diseased tissues from crowns in dry weather and leave wounds exposed to the air.
