Grape vines are susceptible to anthracnose before flowering all the way through fruit soften and coloration. Essentially, the berries are susceptible to the pathogen throughout the growing season. Anthracnose presents itself on the berries as small reddish circles, around a quarter inch in diameter, that will become sunken with a narrow dark brown to black border. Eventually, the center of the lesion will change color from violet to white or grey and become velvety. These lesions often look like a shooting target or bullseye. Should the disease spread to and affect the pulp of the berry, it will cause cracking, which opens the berry to secondary infections.
