Technical Abstract: Fungicide studies were conducted at Hammond, LA and Poplarville, MS during the 2002 and 2003 fruiting seasons. Ten (MS) or 13 (LA) fungicide treatments were applied at 7-10 day intervals to the strawberry cultivars, Camarosa (LA), Chandler (MS) and Pelican (MS). Berry diseases were identified and counted at harvest. The amount of fruit diseases, particularly anthracnose and gray mold, was low. Stem-end rot caused by Gnomonia comari was prevalent and was controlled by the combination fungicides, Elevate + Captan, Pristine, and Switch. Gray mold incidence was reduced by Scala, Elevate + Captan, Pristine, Switch, boscalid, and Elevate. In at least two of the four trials, the number of berries with diseases symptoms was lowest on plots treated with Pristine, Switch, Cabrio, Captevate, Captan, and Quadris.
