Abstract
Rice plants are disclosed with multiple sources of resistance to herbicides that normally inhibit a plant's acetohydroxyacid synthase (AHAS) enzyme. Besides controlling red rice, many AHAS-inhibiting herbicides also effectively control other weeds that are common in rice fields. Several of these herbicides have residual activity, so that one treatment can control both existing weeds and weeds that sprout later. With effective residual activity against red rice and other weeds, rice producers now have a weed control system superior to those that are currently available commercially.
Claims53
A rice plant wherein:
- (a) the growth of said plant is resistant to inhibition by one or more of the following herbicides, at levels of herbicide that would normally inhibit the growth of a rice plant:
- imazethapyr, imazapic, imazapyr, nicosulfuron, imazaquin, imazamox, metsulfuron methyl, thifensulfuron methyl, tribenuron methyl, pyrithiobac sodium, or a derivative of any of these herbicides;
- and
- (b) said plant is the plant with ATCC accession number PTA-904.
