Chemical pest management options for growers with only a few vines are limited. While non-restricted use pesticides can be purchased and used by anyone (meaning, anyone who reads and understands the pesticide label prior to application and applies it legally), they usually come in package sizes intended for commercial growers with at least several acres of vineyard. This article is intended for the small/homeowner/backyard/hobbyist grower producing a small amount of grapes for their personal use (or to share with friends).

Small vineyard owners often find that they need to spray chemicals for control of weeds, insects, and disease, but can’t justify the expense of a tractor-operated sprayer (not to mention the tractor). The need for chemical applications to control grapevine diseases can be minimized by selecting cultivars that are relatively disease-resistant, and by planting the vineyard in a location with full sunlight and good air movement. However, in humid climates, some fungicide applications are almost always needed to maintain a healthy canopy of leaves and/or disease-free fruit. Most fungicides are applied to prevent the development of diseases, while insecticides are usually applied when insects are present and have met or exceeded established thresholds. In very small vineyards weeds can be controlled by hand-pulling or hoeing, or by applying organic or synthetic mulches, but larger vineyards often require the application of chemical herbicides. Finally, wildlife predation by deer, rabbits, and birds is sometimes accomplished with the use of exclusion devices such as fences and netting, but repellant sprays are sometimes needed to minimize predatory damage to young vines or to fruit.
