For commercial growers, the disease is primarily controlled by use of fungicide sprays. Fungicides are much more effective when applied early in the season when the inoculum load is low as cherry leaf spot is a prolific, unrelenting, tireless disease. Fungicide applications should begin at petal fall or shortly after leaves have unfolded.
Fungicide residues have been found on food for human consumption, mostly from post-harvest treatments. [16] Some fungicides are dangerous to human health, such as vinclozolin, which has now been removed from use.
