Grape farmers in Wisconsin are facing a growing threat, and in many cases it is coming from their own neighbors.
Herbicides that are used to kill weeds in crops such as corn and soybeans can be deadly to other plants, including grapes. Food or wine grape vines exposed to the chemicals may shrivel up, turn colors and grow strange, elongated new leaves.
