Dichondra

Description

Dichondra is a perennial, spreading by slender creeping stems that root at the nodes. It forms mats not over 1½ to 3 inches tall. The kidney-shaped to nearly circular leaves grow alternate to each other, sometimes appearing whorled on the stems. The white to greenish small flowers are borne in clusters in the leaf axils below the level of the leaf. Dichondra is cultivated as a ground cover in some states.

Cultural Control

Perennial broadleaf 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.

Chemical Control

Herbicide and Formulation
Amount of Formulation per 1,000 sq ft
Amount of Formulation per Acre
Pounds Active Ingredient per Acre

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

thiencarbazone-methyl + iodosulfuron + dicamba, MOA 14 + 2 + 4 (Celsius WG) 68 WG

Amount of Formulation per 1,000 sq ft

0.057 to 0.113 oz

Amount of Formulation per Acre

2.5 to 4.9 oz

Pounds Active Ingredient per Acre

0.106 to 0.208

Precaution and Remarks

For use by licensed applicators in residential and commercial lawns, golf courses (excluding greens), sports fields, parks, recreational areas, roadsides, school grounds, and sod farms. Provides up to 60 days residual control. Use on bermudagrass, zoysiagrass, centipedegrass, and St Augustinegrass. Apply maximum 7.4 ounces per acre per season. Safe to use at high temperatures. Ryegrass can be overseeded 2 weeks after application. Apply 30 days prior to seeding bermudagrass or zoysiagrass. Wait 2 weeks after bermudagrass seedlling emergence or sprigging operation before applying. For zoysiagrass, wait 3 weeks after seedling emergence before applying. A nonionic surfactant or methylated seed oil at 0.25% v/v is required for optimum control.

Postemergence Control

Herbicide and Formulation

2,4-D amine, MOA 4 (various brands) 4 SL

Amount of Formulation per 1,000 sq ft

3 to 4 tsp

Amount of Formulation per Acre

1.5 to 2 pt

Pounds Active Ingredient per Acre

0.75 to 1

Precaution and Remarks

Cut rate one-half for bentgrass, carpetgrass, centipedegrass, and St. Augustinegrass. Spray when weeds are young and actively growing. To reduce danger of injury to flowers and ornamentals by spray drift, use low pressure and do not spray on windy days.
