Pest Management

Grapes certainly have their share of insects, mites, and diseases. Selecting disease tolerant cultivars, good sanitation practices, managing vine canopies for good air movement, pest scouting, and an effective spray program are all part of a successful pest management program. Common grape diseases are black rot, downy mildew, powdery mildew, phomopsis cane and leaf spot, and botrytis bunch rot or gray rot. Major insects and mites on grapes are grape berry moth, Japanese beetle, grape flea beetle, European red mite, grape root borer, and grape phylloxera. Refer to OSU Extension Bulletin 780, Controlling Disease and Insects in Home Fruit Plantings, and Bulletin 506 B2, Ohio Commercial Small Fruit and Grape Spray Guide, and Bulletin 861, Midwest Small Fruit Pest Management Handbook for more information. There are also fact sheets available on the control of selected grape diseases and insects.

Home fruit growers can have a great deal of success with grape production if they know what is involved and are willing to do the work. It is also a very rewarding experience to be able to grow your personal favorite grapes that are not available in grocery stores or farmers¼ markets. In addition, home grape growers will get a greater appreciation of high quality grapes produced by farmers.
