As Midwest vineyards move in next door to longstanding fields of corn or soybeans, they don’t always make good neighbors. Occasionally, herbicides like 2,4-D drift beyond their target, and for nearby vineyards the results can be devastating.
2,4-D is a common herbicide used by farmers because it kills weeds but doesn’t kill their corn. Landscapers and golf courses use it on lawns and fairways. Highway crews often spray 2,4-D on road ditches.
