TTU Vineyard Advisor

The Vineyard Advisor provides recommendations for management of more than 360 problems afflicting grapes nationwide, from diseases, insects, mites, nematodes and wildlife, to environmental stress, physiological disorders and weeds.

Recommendations are given for disease and pest control strategies and action thresholds, natural controls and cultural practices, organic materials, and pesticides. The most current list of all pesticides labeled for use on grapes to control a specific problem is retrieved from the EPA label database. Complete pesticide labels are available in PDF format for most products. Two search options are available to the user: search the database for grape problems by common name, or search for pesticides labeled for use on grapes. The pesticide search can be done by product name or active ingredient.

Weed management recommendations provide cultural practices and general recommendations, as well as special considerations for difficult to control weeds, or those that have developed tolerance to herbicides. The most current list is provided of all herbicides labeled for use on grapes to control a specific weed; organized by preemergence and postemergence herbicides.

Additional resources include ratings of pesticide efficacy in controlling grape diseases, insects, weeds, and other pests; fungicide use requirements (reentry interval, pre-harvest interval); FRAC resistance class, and additional information on fungicide resistance. External links are provided to the Organic Materials Research Institute database of approved organic products, and several pest identification websites. Location-specific links are provided to the user’s state agricultural extension service and pesticide regulatory agency.

The Vineyard Advisor is produced by the Viticulture and Enology program at Texas Tech University and is managed by Edward Hellman, Professor of Viticulture and Enology.
