Ohio grain farmers are using dicamba and 2,4-D more frequently against herbicide-resistant weeds. These herbicides are stronger and prone to off-target drift. A new video from Ohio State discusses the high cost of drift damage on specialty crops, ranging from lower yields to delayed or lost harvests and even the loss of long-term investments like grape vines or certification status.
2,4-D and dicamba are synthetic auxins, herbicides that affect multiple growth processes by mimicking natural plant hormones. Not all plants are highly sensitive to synthetic auxins, but most will react to exposure in characteristic ways (see photos). Damage is usually characterized by severe distortion of stems and leaves but can also cause delayed or uneven fruit ripening and plant loss.
