What is Field Bindweed?
Field Bindweed is a creeping, deep-rooted, perennial weed native to Europe and Western Asia. It is suspected that Field Bindweed arrived in the United States around the mid-eighteenth century when it was utilized as an ornamental and medicinal herb. This hardy weed can be found throughout all of Kansas and most of the Continental United States.
What does Field Bindweed look like?
Mature Field Bindweed plants have leaves that vary in size and shape. Leaves are typically egg to arrowhead shaped and range from 1/2" to 2" long, depending on environmental conditions. Leaves alternate along the stem and are attached by a short leaf stalk, or petiole.
Field Bindweed is a low-lying plant with vines that trail over soil and other vegetation, often causing dense mats. Like many vining plants, Field Bindweed often climbs objects for support. It is commonly found growing on upright plants such as trees, shrubs, or grapevines with its stems and leaves entwined throughout the plant.
Field Bindweed flowers are trumpet, or funnel-shaped, approximately 1" in diameter and bloom in pink or white. They often resemble a small Morning Glory.
Why is Field Bindweed such a big deal?
Field Bindweed is infamous for its ability to multiply. This non-native plant can spread to smother or out-compete millions of acres of crops. Bindweed can form tangled mats, run along the ground, twist and twine around other plants, and climb up a multitude of plants and structures. Each plant can produce up to 500 seeds that remain viable for 50 years. But, bindweed’s biggest threat is what it is hiding underground.
Field Bindweed has an extensive root system of both vertical and lateral roots. Vertical roots can reach depths of 30 or more feet while the shallow lateral roots extend far enough to potentially reach from one pasture to the neighboring pasture. Each of those creeping, lateral roots can produce a number of new plants in addition to those that are a product of viable seeds.
How is Field Bindweed controlled?
Current research indicates that Field Bindweed may be controlled with the following approved control programs.
- Competitive Cropping
- Appropriate and Timely Cultivation
- Application of Approved Herbicides
What Herbicides are approved?
Herbicides currently recommended and approved for control of Field Bindweed are as follows:
When should I apply herbicides?
Field Bindweed is typically treated from May to October. It is important to remember that regardless of the month, plants must be actively growing at the time of application in order for treatment to be effective.
