Fungicide trials against strawberry fruit rot (Botrytis cinerea Fr.) were conducted in 1968, 1969 and 1970 on cv. Cambridge Favourite. Dichlofluanid was applied at 6 lb a.i./acre/year (6.72 kg/ha), tetrachloroisophthalonitrile at 7.5 lb a.i./acre/ year (8.41 kg/ha) and benomyl at 1.5 lb a.i./acre/year (1.68 kg/ha). The first spray was applied when two or three flowers per plant had opened, and one, two or three subsequent applications were made at approximately 10-day intervals. Three or four applications gave better control than two. Application of any of the three fungicides reduced fruit rot and resulted in improved yield. Benomyl and tetrachloroisophthalonitrile caused malformation of fewer fruits than dichlofluanid.
