1. A method for growing a monocotyledonous plant, the growth of which is resistant to an herbicide, comprising:

  • cultivating a monocotyledonous plant, the growth of which is resistant to inhibition by a 2-(2-imidazolin-2-yl)pyridine herbicide, or an herbicidal derivative thereof, at levels which normally inhibit the growth of that species of plant by inhibiting the activity of acetohydroxyacid synthase, wherein said resistance is conferred by an altered acetohydroxyacid synthase whose activity is resistant to inhibition by said herbicide or derivative at levels of said herbicide or derivative which normally inhibit the activity of an unaltered acetohydroxyacid synthase of that species of plant, in the presence of said herbicide or derivative at levels which normally inhibit the growth of that species of plant.
