Pink purslane (Portulaca pilosa) is a summer annual weed that can reach 8 inches in height. The leaves are thick and fleshy, arranged alternately on the stem, and low and spreading along the ground. Leaves are usually 1 inch long, and rounded with a slight point at the end. The flowers are bright pink, and have five petals. The plant blooms in late spring and early fall. Pink purslane is usually found in dry, sandy areas.
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.
|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|
|mesotrione, MOA 27 (4 SC) (Tenacity)||0.092 to 0.183 fl oz||4 to 8 fl oz||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 prodiamine 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.|
|[sulfentrazone + prodiamine], MOA 14 + 3 (4 SC) (Echelon)||0.184 to 0.826 fl oz||0.5 to 2.25 pt||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 inch 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. [Sulfentrazone + prodiamine should not be applied to cool-season turf with N-containing fertilizers unless some short-term discoloration is tolerable.|
|carfentrazone-ethyl, MOA 14 (1.9 EW) (various brands)||0.0126 to 0.048 fl oz||0.55 to 2.1 fl oz||0.008 to 0.031|
|Precaution and Remarks: May be applied to bahiagrass, bermudagrass, buffalograss, centipedegrass, St. Augustinegrass, zoysiagrass, Kentucky bluegrass, tall fescue, fine fescue, perennial ryegrass, and bentgrass. To expand the weed spectrum and extend control of the weeds listed here and on the label, carfentrazone-ethyl can be tank mixed with the entire range of phenoxy products—amines, esters, and other salts—and is also compatible with dicamba, atrazine, glyphosate, glufosinate, clopyralid, triclopyr, and MSMA. When applied alone, add 0.12 to 0.25% nonionic surfactant.|
