Última Chitosan reduces infection by Guignardia citricarpa in postharvest 'Valencia' oranges BABT Rappussi,Maria Cristina Canale; Pascholati,Sérgio Florentino; Benato,Eliane Aparecida; Cia,Patrícia. Citrus fruits are affected by the black spot disease caused by Guignardia citricarpa. Resistance induction is an alternative control measure and chitosan exhibits potential as resistance inducer. The effect of chitosan on G. citricarpa was evaluated in vitro and in 'Valencia' oranges. Citrus fruit were immersed into different chitosan concentrations. Chitosan (2%), combined with or without thiabendazole and the citric acid was also investigated. All the chitosan concentrations inhibited G. citricarpa mycelial growth and affected morphologically the conidial germination and appressorium formation. Chitosan inhibited the development of new lesions in oranges at room condition or under refrigeration. Thiabendazole and citric acid did not reduce the formation...

ABSTRACT: The aim of this study was to evaluate the ethanolic extract of green propolis (EEP) in the protection of common bean plants against two main bacterial cultures, bacterial blight (Xanthomonas axonopodis pv. phaseoli) and wildfire (Pseudomonas syringae pv. tabaci). Experiments on antimicrobial activity were performed, inducing phytoalexins, defense-related enzymes, and disease severity, under concentrations of 0, 0.5, 1.0, 2.5, and 5.0%. The EEP presented antimicrobial activity on both phytobacteria, causing a decrease in their development. It has also promoted a linear accumulation of phaseolin in bean hypocotyls according to the EEP concentration used. There was a reduction in the lesion area, which was caused by bacterial blight on bean leaves...
