Preplant incorporated herbicides, such as dinitroanalines, may cause injury to tobacco when they are improperly applied or not uniformly incorporated. Typical injury symptoms include seriously pruned root systems which result in stunted root growth and irregular field appearance. Affected plants exhibit a deficiency of feeder roots in the zone of herbicide incorporation. Most secondary and feeder roots terminate in blunt knob-like tips. Injury is also more common when cool wet weather persists after transplanting, or when excessively high rates of herbicides are used.
