Seedlings of field bindweed are easy to control with cultivation, but only for about 3 to 4 weeks after germination. It has an extensive deep fibrous root system and reproduces/spreads from seed and roots. Experiments in some annual and perennial crops have demonstrated the effect of shade on bindweed growth. 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.

Herbicides have been relatively effective for suppression of bindweed, but In addition rhizomes have the ability to penetrate through fabric, plastic, and other barriers. For control, products containing trifluralin, oryzalin, or pendimethalin applied before emergence will reduce perennial shoots and control the germinating seedlings, but they won’t kill established bindweed plants. Its seed has a long dormancy and can last in soil for up to 60 years. Systems Approach to Control of Field Bindweed. Because the seed lasts such a long time in the soil, control practices must be conducted continuously. Generally, additional applications need to be made when the bindweed regrows. Within a month, the seed coat has matured and become impervious to water. It is a ground cover over bare ground or short grass and a climber where there is competition.
