Fall Scab Inoculum Reduction Strategies
Mike Basedow, Tree Fruit Specialist
Eastern New York Commercial Horticulture
While scab was relatively light in 2021 throughout much of the Eastern NY region, there may be some problem blocks here and there that would benefit from inoculum reduction strategies this fall. The objective of inoculum reduction is to eliminate a large proportion of the ascospores that would otherwise be produced in overwintering leaves. Fungicides applied next spring will be more effective when applied in these reduced inoculum orchards.
