Protecting your vineyard grapes from the environment is a challenge that takes some cunning. Throughout the growing season you will want to ensure that your grapes are protected from disease as well as from pests like birds and insects, but also deer and other large grazing animals that may roam free where you live.
Fungus and Disease
There are several diseases that can harm the grapes in your vineyard. Some common ones are mildew, fungus and black rot, all forms of fungus and so fungicide is the most common cure. However the right cure is necessary for the right disease. Most disease is recognized by its effect on the vine leaves. Examine the plants in your vineyard regularly and once grapes are visible, inspect those too for signs of decay. For example, small yellow spots with dark brown centers could be signs of phomopsis cane. Generally, leaf discoloration, or spots on the leaves are signs of problems. You might also see a film over the leaf or the berries may show signs of rotting before they are ripened.
Insect Pest Control
Some of the most common insects that affect vineyards and threaten your grape production are moths, leafhoppers and beetles. The Berry Moth lays its eggs directly on the grapes. The young larvae eat their way through the center of your grapes, leaving tell-tale holes. Leafhoppers tend to accumulate on the underside of the vine leaf. Leafhoppers don’t do that much damage unless they become densely populated and then they can damage the crop. Rose chafers and Japanese beetles feed on the grape clusters as they mature on the vine.
