Only 1 of 16 applications of imazapyr at 0.56 kg ha-1 controlled less than 90% regardless of plant vigor. "It is considered to be one of the most noxious weeds in the world," says Andy Hulting, OSU weed specialist. Holt, Jodie. In conjunction with cultivation, withholding water to dry the site might help to reduce the perennial population in a summer season, assuming the roots have not tapped into deep moisture. Use a translocated herbicide, such as glyphosate, or a combination of glyphosate and dicamba, in areas where its use is allowed, when the plant is actively growing. Selective. It won’t affect germination of field bindweed seed, so new seedlings will have to be controlled with mulch, preemergent herbicides, or persistent cultivation.
