Abstract

Yields and fruit quality of French prune trees in Tulare and Yuba counties were not improved by controlling late-season prune rust with mancozeb or sulfur over a 3-year period. Accelerated postharvest leaf loss induced by disease did not appear to cause a decline in yields in the following year. In a comparison of mancozeb 80W and sulfur 92W for control of prune rust, mancozeb provided superior control.
