Phomopsis cane and leaf spot is a disease that causes symptoms in the common grapevine species, Vitis vinifera, in many regions of the world. [2] This disease is mainly caused by the fungal pathogen, Phomopsis viticola, and is known to affect many cultivars of table grapes, such as Thompson Seedless, Red Globe, and Flame Seedless. [3]
If the infection has spread throughout a larger area, it may be best to remove the affected limb of the plant to reduce further spread. Fungicides may be used as treatment. There are a number of remedies used to prevent the spread of black leaf disease, including mixtures of baking soda, soap, vegetable oil, and water. [3] [unreliable source]
Grape vines and their canopies. In viticulture, the canopy of a grapevine includes the parts of the vine visible aboveground - the trunk, cordon, stems, leaves, flowers, and fruit. The canopy plays a key role in light energy capture via photosynthesis, water use as regulated by transpiration, and microclimate of ripening grapes. [1]
Vines are trained into a variety of styles that aid the growers in managing the canopy and controlling yields. The use of vine training systems in viticulture is aimed primarily to assist in canopy management with finding the balance in enough foliage to facilitate photosynthesis without excessive shading that could impede grape ripening or promote grape diseases.
Should the lesions spread and the infection make it into the vascular system of the leaf, the anthracnose will prevent the proper development of the leaf and will lead to malformation or to the drying of the leaf. [citation needed] Grape vines are susceptible to anthracnose before flowering all the way through fruit soften and coloration.
