Chapter 21

Managing Vineyard Insect and Mite Pests

(book excerpts)

Pest management is an important and integral part of wine grape production. Pests cause extensive damage and are responsible for two major kinds of damage to grapevines. First is direct injury to the grapevine by pests feeding on leaves, shoots, roots, and grapes. The second type is indirect damage in which the pest itself does little or not harm but transmits a bacterial, viral, or fungal infection to the vines. To manage these pests in the vineyard, it requires implementing an integrated pest management program, which consists of the following: 1) monitoring the populations of the major pest species in the vineyard; 2) using action thresholds based on pest populations to determine when a spray should be used to control a pest; and 3) when possible, using an effective and safer alternative to reduce pest populations.
