reating weeds in the fall is one of the best things you can do for turfgrass. Targeting fall-germinating weeds like chickweed, henbit and annual blue-
grass with a pre-emergence herbicide is the path of least resistance to a lush lawn next spring. "Most of the time, it's a lot more cost-
effective to treat weeds pre-emergently," says Laurence Mudge, manager, technical services of the Green Solutions team at Bayer. "It's been proven that pre is the way to go. Otherwise, you're going to be out there three or four times to get weeds. During the years, pre-emergence herbicides have become a major tool in our weed-control arsenal."
Whether you're working with cool- or warm- season grasses, the introduction of new chemistries has made it easier than ever to achieve season-long control of winter weeds, even for areas that require reseeding – a category for which pre-emergence herbicides used to be a no-no.
