What are the symptoms of Corvus activity on weeds?
Typically, weeds are controlled so early that they may appear to never have emerged in the corn crop. Those weeds that do emerge may appear bleached or chlorotic (yellow), may be stunted and will eventually result in dead tissue and plant death. Bleached or chlorotic weed symptoms are likely to be observed following rain of one-half inch or more when weeds have emerged during a dry period following planting.
