5) The cultural, biological, and chemical control strategies that can be used for optimal production of commercial grapes. Bloom Time Grape Disease Control (A Power Point file updated June ) Order E, the Michigan Fruit Management Guide (updated annually) includes grapes and has information for selecting pesticides and other pest control. Types of pests that attack vineyard grapes and how to prevent and get rid of them. Pest and Disease Control of Vineyard Grapes.

They have mostly been a problem in the northeastern United States, but there is concern that they may be moving towards the west.

Control of most insect pests is a matter of inspecting vines. When an insect problem is detected, an appropriate insecticide should be applied. Grape berry moth is an exception to this strategy. This pest directly attacks the fruit, so by the time it is detected, fruit has already been damaged. Berry moths may never be a problem for many vineyards. Invasive Insect Alerts.

Field Monitoring for Viruses and Mealybug in PNW Vineyards .pdf. Grapes may be grown in all parts of Tennessee. However, not all types of grapes or varieties of grapes are adapted to all parts of the state. With proper attention to selection of the correct type and variety of grapes, site selection and reasonable cultural practices, grapes can be a viable crop for both commercial and hobby growers. Grapevines are susceptible to a number of pests. Mites, scales and mealybugs are only a few of the insects that are likely to plague vineyards at one time or another. However, since the grapes on your grapevine will ultimately be consumed, even organic pesticides should be avoided. The first step to controlling pests.

Pest Management Guide for Wine Grapes in Oregon EM page 2 pests. Pest control starts with correctly identifying the pest, whether it is a weed, insect or disease, as well as understanding how that pest develops in relation to the crop and the season. All of these parameters will help determine the stage(s) at which the pest is. In areas where this insect previously has been a problem, apply control sprays to plantings when shoots are 4 to 6 inches long. Grape cane girdlers, Ampeloglypter ater (LeConte), are small (1/8-inch), black weevils that girdle grape canes by chewing two series of holes several inches apart. The girdles are generally beyond the last grape.
