Fenpropimorph and flutriafol added to agar at 10–500 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.
