[Allium vineale L.]
garlic is a perennial plant with an odor of garlic which develops from a basal
bulb covered by a membranous coat. At maturity, the bulb is covered with small
yellowish bulbs, flattened on one side, which readily split apart. Leaves are
hollow and round. The greenish pink to purplish flowers are borne in clusters
at the stem tip and are often mixed among small greenish aerial bulblets.
upright leaves are slender, round, and hollow and resemble
bulbous; fibrous roots are attached to the bottom of the bulb

turf weeds are capable of living more than two years. They thrive in weak, thin
turf; golf fairways and roughs; home lawns; playfields; and industrial grounds.
Proper turf maintenance is the key to control of this weed. First, select
adapted turfgrass cultivars for your area and then properly fertilize, mow, and
water to encourage dense growth.
Wild garlic can be controlled in
the fall, preferably, or in spring with 2,4-D plus a nonionic surfactant. Apply
for 2 years to get over 90% control. Wild garlic is also controlled with
imazaquin (Image) and various sulfonylurea herbicides including metsulfuron
(Manor, Blade, etc.).

Efficacy ratings are based on
herbicide trials performed by weed scientists at North Carolina State University between 1997 and 2007. The number of trials included in the efficacy ratings
is displayed in the next-to-last column. The higher this number, the more
confidence can be placed in the efficacy values. Trials may have involved
sequential applications of one or more chemical. Details of individual trials
(herbicide rates, dates of application, environmental conditions at time of
application, etc) can be viewed on the TurfFiles web site, through the Turf Weed Management
Efficacy ratings for chemicals
lacking trial data are from “Pest
Management Strategic Plan for Turfgrass in the Southern United States,”

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.
