• Abstract

  Corynespora cassiicola is the causal agent of the target spot in leaves of several cultivated species, especially cucumber, where reports of damage in greenhouse cultivation conditions have been very frequent. Due to the difficulty of disease management, related to the lack of information on the resistance of cultivars and the absence of registered pesticides for cucumber disease in Brazi…

• Abstract

  A major problem in the commercialization of avocados is the incidence of postharvest diseases, which coincides with the ripening of fruits. The main postharvest diseases are anthracnose (Colletotrichum gloeosporioides) and stem end rots (Lasiodiplodia theobromae, Fusicoccum spp. e Neofusicoccum spp.), called quiescent disease because infect developing fruit in the field and the symptoms e…

• Abstract

  A major problem in the commercialization of guavas is the incidence of postharvest diseases, which coincides with the ripening of fruits. The blossom-end rots are caused by Botryosphaeriaceae species, however, accurate information about the species that occur in guava is needed, as well as data on environmental requirements for infection and the control of these pathogens. This project ai…

• Abstract

  The target spot, caused by Corynespora cassiicola, occurs in several cultivated species, being considered an important disease in cucumber. This project aims to determine the response of the cucumber to the target spot according to the age of the plant, seeking to avoid economic damage to producers and to present a recommendation for preventive management of the target spot with fungicide…
