The subject invention relates in part to the control of AAD-1 monocot volunteers in fields planted with dicot crops such as soybeans or cotton. According to some embodiments of the subject invention, cyclohexanedione herbicides are selected as being an effective tool for controlling AAD-1 volunteers, as AAD genes do not impart tolerance to this class of graminicide chemistry. In addition, imidazolinone-class herbicides can be used in some preferred embodiments for selective control of conventional or herbicide-tolerant varieties of volunteer corn. AAD-1 corn comprising Event DAS-40278-9 is used in some particularly preferred embodiments.
