Corvus® herbicide has the unique feature, reactivation, that sets it apart from other herbicides. It makes the residual control of Corvus last longer than the competition, regardless of weather conditions. During dry periods, other herbicides stop working and don’t come back. But Corvus remains in the soil and with a half inch of rain, reactivates to take out emerged weeds and keeps new weeds from emerging as long as there is sufficient moisture.
