CALCIUM APPLICATIONS BEFORE HARVEST AFFECT THE SEVERITY OF ANTHRACNOSE FRUIT ROT OF GREENHOUSE-GROWN STRAWBERRIES
Fruit rot development was rated 72 hr and 96 hr after inoculation. In Study I fruit from plants receiving drench or foliar applications of calcium sulfate developed less fruit rot than fruit from plants receiving water or the calcium chloride or calcium nitrate treatments. Fruit from plants receiving foliar applications of CaCl2 developed less fruit rot than that from plants receiving soil applications of calcium chloride. In Study II, calcium sulfate at 2.5 mM and ¼X Hoagland's solution resulted in the lowest fruit rot severity ratings.
