Evaluation of Fenpropimorph and Flutriafol for Control of Sour Rot, Blue Mold, and Green Mold in Lemon Fruit. Eliahou Cohen, Associate Research Professor, Department of Fruit and Vegetable Storage, Agricultural Research Organization, The Volcani Center, P.O.B. Bet Dagan 50250, Israel. . Plant Dis. 73:807-809. Accepted for publication 27 March 1989. Copyright 1989 The American Phytopathological Society. DOI: 10.1094/PD-73-0807.

Fenpropimorph and flutriafol added to agar at 10500 ppm completely inhibited growth of most postharvest pathogens of citrus fruit. When these fungicides were applied to lemons within 24 hr after inoculation with Geotrichum candidum or within 48 hr after inoculation with Penicillium italicum or P. digitatum, the subsequent development of disease was significantly reduced. Experimental treatment of lemons at a packinghouse with these chemicals reduced postharvest decay up to 94% of the control. Lesions and sporulation at inoculation sites on treated fruit appeared to be arrested. No phytotoxic effects were evident on citrus fruit treated with these fungicides.
