Molecular detection and quantification of Colletotrichum abscissum in sweet orange propagative material

“…In the greenhouse, C . abscissum was shown to survive for up to 7 months on leaves with intermittent simulated rainfall or only 3 months without rainfall; in the field, the pathogen was isolated from leaves for 7 months in rainy periods and 3 months in the dry season (Pereira, 2013). Under the same controlled conditions, C .…”

“…Although PFD symptoms are not observed on citrus leaves, C. abscissum may produce appressoria on the leaf surface and survive on citrus and weed leaves Frare et al, 2016;Savi et al, 2019;Zulfiqar et al, 1996). In the greenhouse, C. abscissum was shown to survive for up to 7 months on leaves with intermittent simulated rainfall or only 3 months without rainfall; in the field, the pathogen was isolated from leaves for 7 months in rainy periods and 3 months in the dry season (Pereira, 2013). Under the same controlled conditions, C. abscissum did not colonize citrus leaves, with or without injury, but the pathogen produced a large amount of secondary conidia on the leaf surface, which may be an important mechanism for its spread (Savi et al, 2019).…”
