The present invention provides methods for preparing herbicide tolerant corn plants. Also provided are herbicide tolerant corn plants, as well as seeds and progeny derived from these plants.

Gene combinations for herbicide tolerance in corn

Maize plants are grown in a planting area that are tolerant of inhibition by a cyclohexanedione herbicide, an aryloxyphenoxypropanoic acid herbicide, or mixtures thereof, at levels which normally inhibit growth and development, wherein said tolerance is conferred by an altered acetylcoenzyme A carboxylase (ACCase) tolerant of inhibition by the herbicide at levels which normally inhibit the activity of an unaltered ACCase. Additionally, an effective quantity of the named herbicide is applied so that the weeds (e.g., grass) are killed and the maize plants are uninjured. A representative cyclohexandione herbicide is sethoxydim and a representative aryloxyphenoxypropanoic acid herbicide is haloxyfop. Competition for the maize crop posed by weeds effectively is eliminated.

Method for combating weeds among maize plants

The present invention provides a maize plant wherein the growth and development of said plant is tolerant of inhibition by a cyclohexanedione herbicide, an aryloxyphenoxypropanoic acid herbicide, or mixtures thereof, at levels which normally inhibit the growth and development of maize, wherein said tolerance is conferred by an altered acetyl coenzyme A carboxylase (ACCase) tolerant of inhibition by said herbicide at levels which normally inhibit the activity of an unaltered ACCase.

Method for imparting cyclohexanedione and/or aryloxyphenoxypropanioc

Corn plants tolerant to sethoxydim and haloxyfop herbicides
