Wild Garlic

Description

Wild 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.

Cultural Control

Perennial 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.

Preemergence and Postemergence Control

Herbicide and Formulation

mesotrione, MOA 27 (Tenacity) 4 SC

Amount of Formulation per 1,000 sq ft

0.092 to 0.183 fl oz

Amount of Formulation per Acre

4 to 8 fl oz

Pounds Active Ingredient per Acre

0.125 to 0.25

Precaution and Remarks

Use on residential turf, golf courses (not greens) and sod farms for pre- and postemergence weed control. Tolerant turfgrasses include St. Augustinegrass, centipedegrass, tall fescue, fine fescue, Kentucky bluegrass, and perennial ryegrass. Add a nonionic surfactant and repeat application after 2 to 3 weeks for improved postemergence control. Tank mix with Barricade 65 WG for extended preemergence grassy weed control. Can be applied at seeding to all tolerant grasses except fine fescue. After turf germination, wait 4 weeks or until turf has been mowed twice before making a postemergence application. Also controls henbit, chickweed, dandelion, white clover, Florida betony, Florida pusley, ground ivy, oxalis, wild violet, creeping bentgrass, and yellow nutsedge.

Preemergence and Postemergence Control

Herbicide and Formulation

sulfentrazone + prodiamine, MOA 14 + 3 (Echelon 4 SC) 4 SC

Amount of Formulation per 1,000 sq ft

0.184 to 0.826 fl oz

Amount of Formulation per Acre

0.5 to 2.25 pt

Pounds Active Ingredient per Acre

0.25 to 1.125

Precaution and Remarks

For use in residential and institutional lawns, athletic fields, sod farms, golf course fairways and roughs, roadsides, utility right-of-ways, railways, and industrial areas. Apply to turf following a second mowing if a good root system has been established. Apply up to 12 fluid ounces per acre to bentgrass at 0.5 inches or higher, fine fescue, and perennial ryegrass. Apply 18 to 24 fluid ounces per acre to perennial bluegrass, tall fescue, and all warm season grasses except St. Augustinegrass (do not apply) and bermudagrass (apply 18 to 36 fluid ounces per acre). For sod production, apply 6 months after establishment, and do not harvest within 3 months. Do not apply with adjuvants or surfactants. Echelon should not be applied to cool-season turf with N-containing fertilizers unless some short-term discoloration is tolerable.

Postemergence Control

Herbicide and Formulation

metsulfuron, MOA 2 (Blade, Manor, or MSM Turf) 60 WDG

Amount of Formulation per 1,000 sq ft

0.003 to 0.02 oz

Amount of Formulation per Acre

0.125 to 1 oz

Pounds Active Ingredient per Acre

0.005 to 0.038

Precaution and Remarks

May be applied to established bermudagrass, zoysiagrass (Meyer or Emerald), St. Augustinegrass, Kentucky bluegrass or fine fescue. Do not apply to turf less than 1 year old. Do not exceed 0.5 ounces per acre on centipedegrass, fine fescue, or Kentucky bluegrass. See label for a complete list of weeds controlled. The addition of 0.25% nonionic surfactant will enhance control. May be used for removal of perennial ryegrass from overseeded warm-season turf species. For bahiagrass control, use 0.25 to 0.75 ounces per acre after spring greenup but before seedhead development. A repeat treatment may be necessary in 4 to 6 weeks.

Some discoloration or delayed greenup may occur on St. Augustinegrass, centipedegrass, zoysiagrass, or bahiagrass if applied while turf is under stress. See label for a complete list of weeds controlled. The addition of 0.25% nonionic surfactant will enhance control.
