Abstract : Unheated (26-32°C) and heated (53°) suspensions of benomyl, imazalil and prochloraz were compared as postharvest treatments for control of anthracnose (Colletotrichum gloeosporioides [Glomerella cingulata]) of Tommy Atkins and Keitt mangoes. Mature-green mangoes were immersed for 20 s in an unheated suspension or 3 min in a heated suspension. Fruit were then held for 16 d at 13° followed by ripening at 24° before examining for decay. Heated dip treatments affected fruit quality of both cultivars. Treatment for 3 min at 53° in tap water, 0.2% benomyl, 0.2% imazalil, 0.2% prochloraz and 0.05% benomyl plus 0.05% prochloraz satisfactorily controlled anthracnose after 16 d storage at 13°. This paper was presented at the 100th annual meeting of the Florida State Horticultural Society, held at Orlando, Florida, USA on 2-5 Nov. 1987.
