Late Sanitation for Disease Management
Mike Basedow, Tree Fruit Specialist
Eastern New York Commercial Horticulture
Fall has finally arrived, and with it, an excessive number of rainstorms and wet weather. Such weather can greatly favor late season diseases such as fruit rots and lead to the accumulation of inoculum for apple scab and Marssonina leaf blotch. While getting tractors into the orchards is still possible, there are opportunities to do some sanitation and significantly reduce disease pressure for next spring. It may be feasible to capitalize on any available labor that might be there for the harvest. Overall, fungal disease pressure was light in 2022, but there may still be some late season apple scab and Marssonina leaf blotch that could lead to increased disease pressure in the following spring.
