Turfgrass species listed on the label include annual bluegrass, creeping bentgrass where specifically directed, fine fescue, Kentucky bluegrass, perennial ryegrass, tall fescue, and zoysiagrass. It is also labeled for use around many established deciduous and evergreen trees, shrubs, herbaceous plants, flowering plants, wildflowers, and selected desirable native grasses.\u003c\/p\u003e\n\u003ch2\u003eTarget Weeds\u003c\/h2\u003e\n\u003cp\u003eExplain controls annual grass weeds including barnyardgrass, foxtail species, goosegrass also called silver crabgrass, hairy crabgrass, Japanese stiltgrass, seedling Johnsongrass, large crabgrass, smooth crabgrass, panicum species, sandbur, and sprangletop. In rights-of-way uses, the label also lists shattercane, roughstalk bluegrass, and wild oats.\u003c\/p\u003e\n\u003cp\u003eExplain temporarily suppresses common bermudagrass and rhizome Johnsongrass. Explain has little or no activity on broadleaf weeds or sedges, so tank mixes or sequential applications may be needed where broadleaf weeds or sedges are also present.\u003c\/p\u003e\n\u003ch2\u003eApplication Notes\u003c\/h2\u003e\n\u003cp\u003eApply Explain to young, actively growing grass weeds for best control. Explain only controls grasses that have emerged at the time of spraying, so repeat applications may be needed where new grass weed germination occurs or where dense weed populations prevent thorough coverage. Visual effects generally begin as yellowing or reddening of the leaf surface followed by weed death.\u003c\/p\u003e\n\u003cp\u003eFor turfgrass applications, use labeled rates based on grass weed growth stage. The label lists 3.5 to 39 fl oz per acre depending on weed size and turfgrass tolerance, with lower rates for very young grasses and higher rates for tillered weeds. Do not mow treated areas for at least 24 hours after application. Do not apply through irrigation systems, and do not apply to drought-stressed turf or ornamentals.\u003c\/p\u003e\n\u003ch2\u003eProduct Information\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eActive Ingredient:\u003c\/strong\u003e Fenoxaprop-p-ethyl 6.7%\u003cbr\u003e\u003cstrong\u003eHRAC Group:\u003c\/strong\u003e Group 1 Herbicide\u003cbr\u003e\u003cstrong\u003eChemical Family:\u003c\/strong\u003e ACCase Inhibitor \/ Aryloxyphenoxypropionate Herbicide\u003cbr\u003e\u003cstrong\u003eFormulation:\u003c\/strong\u003e Water Emulsion\u003cbr\u003e\u003cstrong\u003eEPA Reg.
