Each flush should be protected with fungicide to control the disease. Pruning produces additional flushes, making the disease more difficult to control. Alternate bearing is a problem with Dancy which affects fruit size and quality. Unfortunately the best control for the problem is pruning in large crop years and this contributes to the Alternaria control problem. Dancy has a thin, delicate peel which necessitates careful handling.
Clipping is recommended as the preferred method of fruit removal to avoid plugging.
Fortunately, Dancy is self-fruitful and therefore requires no other pollenizer trees nearby to enhance productivity. Citrus Growing in Florida. University of Florida Press, Gainesville, Florida. Citrus Varieties of the World. Sinclair International Limited, Norwich, England.
