Subject(s): Online resources: In: Egyptian journal of phytopathology 2002.v.30(1)Summary: Survey of lime fruits diseases at different local markets from different governorates in Egypt indicate that sour rot caused by Geotrichum candidum is the most important disease affecting lime fruits. It caused 65% infection of surveyed lime fruits. Green mould (Penicillium digitatum) and blue mould (P. italicum) are less incidence(17.9 & 13.3%, respectively). All chitosan concentrations significantly reduced the linear growth and spore germination of all fungi. Complete inhibition was obtained with chitosan 6g/l for G. candidum and at 8g/l for P. digitatum and P. italicum. Lime fruits coated with chitosan protected the fruits against postharvest fungi.
