¹ FRAC group = Group numbers and letters are used to distinguish the fungicide mode of action. All fungicides within the same group (with same number or letter) indicate same active ingredient or similar mode of action. This information must be considered for the fungicide resistance management decisions. M = multi-site inhibitors; U = unknown, or a mode of action that has not been classified yet; P = host plant defense inducers. Source: FRAC Code List 2022; http://www.frac.info/ (FRAC = Fungicide Resistance Action Committee).

AFR = Anthracnose Fruit Rot; BFR = Botrytis Fruit Rot; PM = Powdery Mildew; ALS = Angular Leaf Spot; CCR = Colletotrichum Crown Rot; PCR = Phytophthora Crown Rot; NPT = Neopestalotiopsis

(+++) = good efficacy; (++) = moderate efficacy; (+) = low efficacy; (-) = no efficacy or not labeled; (nd) = no data, or inconclusive, based on field trials conducted at the University of Florida, GCREC. Note: efficacy for NPT based on a combination of field and lab trials. ^‡based on only one trial

² BFRr: Fungicide resistance of Botrytis populations recovered from Florida strawberry fields

(***) = widespread; (**) = moderate frequency; (*) = low or absent; (nd) = not determined
