It has a vigorous root and rhizome system that makes it almost impossible to control with cultivation between desirable plants or broad scale tillage alone; in fact, it often spreads the infestation. Plants are prolific seed producers, with an average plant producing over 500 seeds. In the landscape, field bindweed will survive with sprinkler or drip irrigation. However, because of its flowers and climbing nature, some seeds were probably planted as ornamentals, as a ground cover, in hanging baskets, or on trellises.

For field bindweed, late summer or early fall is the best time to apply because plants move nutrients into the roots in preparation for winter. Mature field bindweed plants have arrowhead-shaped leaves that can be 1/2 to 2 inches long, depending on environmental conditions. It competes with crop plants for soil moisture and, to a lesser extent, for light. If there is no summer water, the plant reduces its seed production first and then reduces growth and leaf size, but it still will produce some flowers and seed. herbicide than those actively growing. If field bindweed is present, land is devalued and the weed precludes planting of many vegetable crops. Contact webmaster. Selective.

When applying herbicide at this particular cycle of the plant, the leaves will suck in the chemicals and bring it down to the roots and rhizome system. Most parts of the bindweed roots and rhizomes can produce buds that can create new roots and shoots. Calif. Weed Sci. Effective control requires prevention of seed production, reduction of stored carbohydrates by deep tillage of the root system, competition for light from other plants, and constant vigilance in removing top growth.
