spp. are important pathogens of citrus that cause dieback of branches and postharvest disease. Globally, several species of have been identified as causing anthracnose of citrus. One hundred and sixty-eight isolates were collected from anthracnose symptoms on citrus stems, leaves, and fruit from Victoria, New South Wales, and Queensland, and from State herbaria in Australia. sp. nov., , , , and were identified using multi-gene phylogenetic analyses based on seven genomic loci (ITS, , , , , , and ) in the gloeosporioides complex and five genomic loci (ITS, , , , and ) in the boninense complex, as well as morphological characters. Several isolates pathogenic to chili (), previously identified as , formed a clade with the citrus isolates described here as sp. nov. The spore shape and culture characteristics of the chili and citrus isolates of were similar and differed from those of . This is the first report of isolated from citrus and the first detection of and associated with citrus anthracnose in Australia.

A comprehensive dataset on lemon leaf disease can surely bring a lot of potentials into the development of agricultural research and the improvement of disease management strategies. This dataset was developed from 1354 raw images taken with professional agricultural specialist guidance from July to September 2024 in Charpolisha, Jamalpur, and further enhanced with augmented techniques, adding 9000 images. The augmentation process involves a set of techniques-flipping, rotation, zooming, shifting, adding noise, shearing, and brightening-to increase variety for different lemon leaf condition representations.

The hairiness of the leaves is an essential morphological feature within the genus Vitis that can serve as a physical barrier. A high leaf hair density present on the abaxial surface of the grapevine leaves influences their wettability by repelling forces, thus preventing pathogen attack such as downy mildew and anthracnose. Moreover, leaf hairs as a favorable habitat may considerably affect the abundance of biological control agents.

Sorghum anthracnose is one of the major diseases that have negative impacts on sorghum production in Ethiopia. This study was conducted to evaluate the resistance response of sorghum genotypes against sorghum anthracnose and to determine yield performances of sorghum genotypes under field conditions in two consecutive cropping years. Forty-nine sorghum genotypes were tested for their reactions to anthracnose in the East and West Hararghe Zones, East Ethiopia, during the 2017 and 2018 main cropping seasons.
