Kansas City, Mo. - BI/Gordon Corp. introduced new Q4 Plus, an improved formulation of their grassy and broadleaf herbicide containing quinclorac. The other ingredients - sulfentrazone + 2,4-D + dicamba ?EUR??,,????'?????<???(R) remain the same. With the disappearance of MSMA from use on residential and commercial turf, new Q4 Plus offers the professional turf manager more knockout power on grassy weeds. ''Like Trimec Plus, which contains MSMA, Q4 Plus offers a single product control option for grassy and broadleaf weeds and yellow nutsedge,'' said Doug Obermann, Product Manager for Gordon's Professional Products. ''Users appreciate that convenience.'' The fast action of Q4 Plus also gives visual results within 24 to 48 hours ?EUR??,,????'?????<???(R) another bonus for turf managers. ''When their clients see fast results, it reduces the number of call backs that they receive. That's going to save money,'' said Obermann.
Q4 Plus is formulated for use on bluegrasses, perennial and annual ryegrass, fescues and, now, bermudagrass. The EPA approved the new label in December 2009 and state registrations are complete with the exception of California which is still pending. The product has been available for shipment since May.
