A hot water dip at 50 D C for 8 min effectively controlled quiescent infections in red tamarillos (Cyphomandra betacea (Cav.) SendL) caused by Colletotrichum gloeosporioides (Penz.) Arx and C. acutatum Simmonds. This dip reduced the percentage of fruit with body lesions without significantly increasing peduncle necrosis. Fungi colonising damaged peduncle tissue were controlled using an imazalil dip (1 min at 15 -20DC) at 250 mg active ingredient/litre. The method of imazalil application (in hot water, as a separate cold water dip, or in wax) did not affect its efficacy. Imazalil residues in skin, pulp, and whole fruit were lowest when the fungicide was applied as a separate cold water dip. Storage disorders were significantly reduced using the hot water/imazalil dip, allowing 7 days shelf-life at 20 D C after 8 weeks cool storage at 3.5°C.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
