511:. In climates with strong winters, even if the disease does not outright kill the vine, it will reduce its photosynthetic capacity, leading to decreased amounts of carbohydrate reserves in the vine and eventual death in winter as those reserves dry up and the plant is unable to sustain itself. In addition, once the disease afflicts the berries, it will lead to a decrease in quality and quantity, which will have detrimental economic impact as wine makers will have lower volumes of lower quality berries to work with.
490:. This dormant fungicide application is then followed up throughout the season by foliar sprays—sprays that target the surface of foliage. These sprays help protect the new susceptible tissues. Foliar sprays are typically recommended at two-week intervals. Other commercial products often used include Mancozeb, Captan, Ziram, Sovran, Rally, Elite, Inspire Super, Adamant, Mettle, Revus Top, Vintage, and Pristine. The majority of these fungicides are sterol inhibitors and a few are

lethal to the plant, either through defoliation and removal of photosynthetic capacity, or through injury to the active regions of the vine. Grape anthracnose is particularly important to the wine industry, as it can decrease quality and quantity of berries produced as well as kill the vine outright, leading to large economic losses, in particular during the middle summer months.

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.

reddish-brown to violet-black color. If left untreated, lesions on shoots will become larger and eventually kill the shoot. While these lesions may be very apparent and easy to identify, they can sometimes be confused for hail damage. Hail damage typically appears on only one side of the plants. Also, anthracnose lesions will have darker and more raised edge.

Canopy upkeep can be an important preventive measure when dealing with anthracnose. Proper pruning and training will increase air flow around the plant and thus reduce the drying time of external tissue surfaces. Appropriate care is especially crucial for target areas of new growth because they are

Fungicides are a control measure commonly used once grape anthracnose has become established in a vineyard. The most important fungicide application occurs in early spring during the dormant period before bud swell. A lime-sulfur solution is most commonly used. This is typically applied at a rate

Sanitation is a critical factor in controlling grape anthracnose. The removal of infected tissues is done during the dormant stage, often when it is cold and dry in the winter months. The infected tissue must be then be destroyed upon removal. This reduces the amount of primary inoculum available

Anthracnose is possible even before bud break. The infection rate will escalate with increases in

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,
277:
Anthracnose on grape presents itself as lesions on shoots, leaves, and berries. Lesions will first appear on young shoots, showing up as small circular reddish spots that will later become larger and create grey lesions which appear sunken. The lesions will eventually develop margins that are a dark

Wild grape varieties in proximity to cultivated grapes should be removed. The wild species can host grape anthracnose and are a source of primary inoculum. Because the conidia are spread by water splashing, it is not crucial to eliminate all wild grapes, just the ones near the cultivated grapes.
216:
This type of anthracnose affects several plant varieties, including some brambles and wine grapes. Grape anthracnose can be identified by the "bird's eye" lesions on the berries and sunken black or greyish lesions on leaves and shoots. From these lesions, conidia are produced. This disease can be

Anthracnose lesions on leaves and petioles look very similar to those on shoots. However, on leaves, the lesions will have dry grey or white centers that will eventually fall off, leaving a hole. This response by the plant is called a shot-hole. Should the lesions spread and the infection make it

Another control method is ensuring the use of disease-free plantings, although phytosanitary regulations ban the movement of infected plants and propagules. The best way to ensure one is getting disease-free plantings is to buy them from a certified operation with disease-tested grape vines.
