Treatment recommendationsMinimize irrigation, because most turfgrasses can survive with less moisture than dollarweed can. Apply LockUp® specialty herbicide when dollarweed is actively growing. Repeat spring or fall applications may be necessary, as dollarweed can be difficult to control for an entire growing season. State restrictions on the sale and use of LockUp apply. Consult the labels of products containing LockUp before purchase or use for full details. Always read and follow label directions.
Weather can be one of the most unpredictable factors during the springtime rush. Preemergence herbicides are a trusted weed control method this time of year, but they must be applied prior to weed seed germination to be effective. Use this handy table as your guide to answer any questions you have on preemergence weed control.

Application flexibilityCrabgrass is most effectively controlled by using a preemergence herbicide, which works by inhibiting the establishment of young seedlings. To be effective, however, preemergence herbicides must be in place before germination occurs, allowing the herbicide to form a barrier before the crabgrass seedlings emerge.
“Applying a preemergence herbicide such as Dimension specialty herbicide prior to crabgrass germination will optimize performance,” Jamie Breuninger, technical leader for Dow AgroSciences Turf and Ornamental, said. “Dimension will control what is germinating and will put a barrier down to prevent future growth.”Dimension® specialty herbicide offers excellent preemergence and early postemergence control of crabgrass in established lawns; golf course fairways, roughs and tee boxes; and commercial sod farms. Early postemergence crabgrass control also is obtained when Dimension is applied prior to tillering of crabgrass (up to five leaves), typically corresponding to the time when crabgrass seedlings are first observed in turfgrass. Dimension also provides noticeable control of crabgrass treated at the start of tillering. Depending on climatic conditions and rate of growth, the time from crabgrass emergence until tillering will vary from two to eight weeks. The benefit of this product’s early postemergence activity is to provide you with a longer window of application to achieve crabgrass control, allowing you more time to make crabgrass applications.
