Spring freeze damage can be a significant economic problem for Midwest grape growers. Widespread damage occurred in 2007, 2012 and 2017 when warm temperatures in February and March were followed by freezing temperatures. Obviously this year has been very cool so far so there is hopefully less risk of early budbreak and frost damage. But,…Read more about Pruning to Adjust for Winter Injury and Avoid Spring Frost Damage to Grapes[Read More]

We have evaluated crops at the…Read more about Determining Winter Injury in Grape Vines[Read More]

Apple harvest is winding down with late varieties such as GoldRush and Pink Lady being harvested. Quality has continued to be good, although some stem-end cracking has shown up on some cultivars. We have continued to run about a week early throughout the season.
Powdery and downy mildew can develop on grapes in the late season, post harvest. It is important to keep vines as healthy as possible going into winter. With the long fall we are experiencing, downy and powdery mildew are both becoming prevalent in many vineyards. Growers should consider a late season application of fungicides to…Read more about Late Season Leaf Diseases of Grapes[Read More]
