Última Effects of ethanol and ultraviolet-c treatments on inactivation of Rhizopus oryzae spores which cause postharvest rot Ciênc. Tecnol. Aliment. UYAR,Gülsüm Ebru ÖZER; UYAR,Başar. Abstract Rhizopus oryzae is a filamentous fungi reported as a postharvest pathogen in recent years. Ethanol treatment (0, 10, 20, and 30%) and UVC irradiation (0, 1, 2, 5, 10 minutes) were used both individually and in combination for the inactivation of Rhizopus oryzae spores. Survival ratio of the spores and LD50 values for ethanol and UVC irradiation were determined to quantify the germicidal effect. UVC exposure is found to be significantly more effective than ethanol treatment on the reduction of R. oryzae spore survivability. The combination of UVC exposure and ethanol treatment enhanced the lethality of applying each treatment separately and the enhancement increased as the UVC exposure time and ethanol concentrations increased. The lowest spore... Tipo: Info:eu-repo/semantics/article Palavras-chave: Rhizopus oryzae; Postharvest rot; Ethanol; UVC irradiation.

ABSTRACT: One of the major problems in the commercialization of avocados is the incidence of postharvest diseases, especially anthracnose (Colletotrichum spp.) and stem-end rot (Lasiodiplodia theobromae, Fusicoccum aesculi and Neofusicoccum spp.). As there is a lack of epidemiological information on these pathosystems, the objective of this study was to establish a method to detect quiescent infections and characterize their temporal progression and spatial pattern in a commercial orchard. Detection of quiescent infections was evaluated in flowers and fruits that were immature and in commercial harvest stage, treated with paraquat, ethrel or water. Treatment of flowers and immature fruits with paraquat led to rapid detection of Colletotrichum spp. In two...
