Grape Scouting Reports
MSU's grape team will be scouting vineyards and reporting the results through our grape scouting reports. MSU staff, educators and specialists in southwest and northwest Michigan will visit multiple vineyards, check growth stages, monitor traps and sample leaves and clusters. These reports will cover weather, grape phenology, disease and insect information and serve as a platform for us to announce meetings. These reports will be posted on Wednesdays every week throughout the growing season. We will add additional reports as specific issues come up through the season.
The free scouting reports will be included in MSU Extension’s News for the Grape & Wine Industry e-newsletter. If you are not already receiving MSU Extension News, you can sign up by entering your email address with MSU Extension News, then scroll down the list and click the box to select “Grape & Wine industry.” You can also click to select additional topics for other e-newsletters that may be relevant for you.
