[Vicia sativa L.]
vetch is a trailing winter annual weed that forms large mats of vegetation. It
is common to waste areas and roadsides. The leaves of common vetch are very
narrow, alternately arranged and compound. Tendrils form on the ends of the
leaves. Long stems arise from fibrous roots, and flowers are purple. Late in
the season after the flowers drop, seed pods form.

annual broadleaf weeds germinate in the fall or winter and grow during any warm
weather, which may occur in the winter, but otherwise remain somewhat dormant
during the winter. They resume growth and produce seed in the spring and die as
temperatures increase in late spring and early summer. They quickly invade thin
turf areas especially where there is good soil moisture. Shade may also
encourage growth. Many have a prostrate growth habit and are not affected by
mowing. A dense, vigorous turf is the best way to reduce the encroachment of
winter annual weeds. First, select adapted turfgrass cultivars for your area
and then properly fertilize, mow, and water to encourage dense growth.
Postemergence control of common
vetch can occur with two, three, and four way broadleaf herbicides applied in
the fall or spring. Additionally, triclopyr + clopyralid (Confront) or
fluroxypyr-containing products (Spotlight, Escalade 2, etc.) provide control.
Recommendations of specific chemicals are based upon information on the
manufacturer's label and performance in a limited number of trials. Because
environmental conditions and methods of application may vary widely,
performance of the chemical will not always conform to the safety and pest
control standards indicated by experimental data. The order in which brand
names are given is not an indication of a recommendation or criticism.
Recommendations for the use of
agricultural chemicals are included in this publication as a convenience to the
reader. The use of brand names and any mention or listing of commercial
products or services does not imply endorsement by North Carolina State
University or discrimination against similar products or services not
mentioned. Other brand names may be labeled for use on turfgrasses. Individuals
who use agricultural chemicals are responsible for ensuring that the intended
use complies with current regulations and conforms to the product label. Be
sure to obtain current information about usage regulations and examine a
current product label before applying any chemical. For assistance, contact
your county's Cooperative Extension agent.
