Identification of the causal agent of leaf spot on citrus in the coffee production area of Colombia


, : Identification of the causal agent of leaf spot on citrus in the coffee production area of Colombia. Fitopatologia Colombiana 19(1): 31-35

Colletotrichum and Alternaria were frequently isolated from necrotic lesions on leaves and fruits of tangelo Minneola, lemon and mandarin in the Quindio region, Colombia. Pathogenicity tests in humid chambers were carried out on plantlets of tangelo Minneola with new shoots, detached leaves, post-bloom fluorescence and fruit. Only material infected with Alternaria and Alternaria + Colletotrichum produced symptoms.

Effect of light on gemmae formation in M. citricolor. Respiration in M. citricolor probably follows the glycolytic pathway but evidence concerning the Krebs cycle was less convincing. Suspensions of mycelial fragments oxidized chlorogenic and ascorbic acids, and fungal filtrates oxidized indoleacetic...
