well spring is almost here (at least in central FL) and even though I have cut way back on watering this winter, Dollar weeds are already running like crazy. Please once and for all, how do I kill these SOB’S !!!

last year when i had some pop up i sparingly used roundup on the leaves, careful not to get it on the surrounding grass. the zoysia will come back however, even after contact with roudup.

you might also try baking soda.

Don’t do it. Roundup is damaging in this situation. At your latitude zoysia is not dormant now and Roundup is not selective so it will kill the zoysiagrass. And it is not realistic to paint the Roundup on dollarweed leaves because they are so many.

Hire a licensed PCO (in Florida, the Commercial Pest Control Operator Certification, Chapter 482, Florida Statutes) to do this because a licensed PCO should have access to the chemicals and have the know-how to do this.

Herbicides that selective kill dollarweed without harming zoysia (if applied according to label) are Certainty (sulfosulfuron) and metsulfuron (brand names Manor, Blade, MSM Turf, and Mansion).
