Abstract
Two orchard sprays with 800 ppm methyl l-(butylcarbamoyl)-2-benzimidazole-carbamate (benomyl) or three orchard sprays with 300 ppm 2-(4-thiazolyl) benzimidazole (thiabendazole or TBZ) achieved significant control of storage decay of ‘Spadona’ pears (Pyrus communis L.). Almost complete control of storage decay required postharvest dip-treatments of 1000 ppm benomyl or 500 ppm TBZ. Penicillium expansum and Botrytis cinerea (Pers. ex Fr.) were inhibited by these treatments but Alternaria tenuis (Nees ex Cda.) was unaffected and its incidence increased during storage, possibly due to control of the other organisms. These benzimidazole treatments tended to increase the incidence of internal breakdown of treated pears during prolonged regular cold storage.Keywords
