Grapes Connecticut

Background

New England is experiencing a growth in the number of farms and acreage dedicated to grapes, made up of small diversified farms as well as those dedicated to grape growing. In 2012, New England had 510 grape producing farms on 1226 acres, while Connecticut alone had 114 farms covering 536 acres. The 2017 Census of Agriculture is expected to show an increase in the number of farms and acreage dedicated to grapes across New England. In 2011, the total economic contribution of the grape growing and winery industries in the New England states (CT, MA, ME, NH, VT) was $70.1 million. This includes 3,260 jobs and $36.7 million in labor income. Vineyards contributed $8.2 million to the total, wineries $38.6 million, and winery tourists $23.3 million.

Objective

This project will allow for up-to-date information regarding the movement of grape pests and beneficials throughout New England to be provided to Extension professionals, growers, and crop consultants.

Training growers in the use and importance of iPiPE is an equally important goal of this project. Providing growers, Extension professionals and crop consultants with this tool to record their findings in the field and then how to use it to aid in IPM decisions (such as timing, threshold awareness, etc) should save them time and money overall. 

A third goal is to train two undergraduate students in the use of iPiPE to upload as well as garner valuable information from other field reporters, proper scouting and IPM techniques, pest and beneficial identification, and the dissemination of information to growers, Extension professionals and crop consultants.


Situation

With climate change, the New England states are not experiencing the steady sub-freezing winter temperatures of previous decades that helped to reduce some pest populations. Growing seasons have recently been warmer than ‘normal’, as well as drier. The impact on new pest outbreaks is evolving. The grape berry moth has been and is continuing to be a problem, as well as the recent arrival of non-native insects, the Spotted Wing Drosophila and Brown Marmorated Stinkbug, the latter considered an agricultural pest in CT and present in the other New England states. The predatory wasp of BMSB, Trissolcus japonicas, has been found as close as the Hudson Valley.

Learning to identify Trissolcus japonicas and other new arrivals (the Spotted Lanternfly is not yet here but may be soon) through scouting efforts will be imperative, as will providing scouting information to Extension professionals, growers, crop consultants and other interested parties.
