Field bindweed is adaptable to different environmental conditions and very difficult to eradicate due to its deep root structure, which can penetrate the soil to a depth of 20 feet with numerous long lateral roots. It can be controlled with biological agents, herbicide, and cultivation. Integrating these methods in certain cropping practices will help to control it. Total eradication is not a realistic short-term goal because the seeds can lie dormant in the soil for decades. With persistence, this weed can be eliminated. ControlBiological: Although it is not productive forage, sheep have grazed it with no reported ill effects. Cattle do not readily graze field bindweed when more desirable forage is present. Swine poisonings have been noted by consuming this weed. There is a gall mite and a moth that are known to target this Noxious Weed, however, availability and insect survival is limited. Herbicide: This department has seen fairly good results in rangeland, pastures, and other non-crop areas by applying products containing metsulfuron, picloram, or dicamba. Picloram is a “restricted use” product and can only be applied by a licensed applicator.When choosing any kind of control method, assure that your choice is suited for your particular situation. Always read and follow the entire product label before applying any herbicide. | |
