Winter Burweed Should be Treated Before It is Too Late
Keith Hawkins, LSU AgCenter, Beauregard Parish

     As a County Agent for the AgCenter, I strive to help homeowners with their lawn question and provide the best research-based information available. However, in my own yard, my attitude towards turf is more lax. I mow the yard and treat for fire ants, and that was it as far as lawn maintenance was concerned. I regard my yard as more of a botanical collection and have learned to identify St. Augustine, Bermudagrass and bahia grass. My yard is also a training lab in learning lawn weeds such as annual bluegrass, henbit, dichondra, carpetweed, and other weeds.

      I have been very tolerant of lawn weeds until I walked barefoot one spring a few years ago and encountered stickers. The stickers became so bad that Gracie, our female Maltese dog, would not walk on the yard. After attending Dr. Ron Strahan’s Master Gardener classes on turf and on weeds, I learned that I have lawn burweed, or stickerweed.

     When the stickers are felt, it is too late to treat. The trick to treating burweed is timing. I have already seen burweed in my yard this month of January so I will be treating soon to prevent the stickers.

     Last February I used an herbicide with the active ingredient call Atrazine and where I applied it in accordance with the label, the treatment was an overwhelming success. I did not treat the whole backyard, but there was enough burweed-free yard that Gracie could comfortably visit the lawn and conduct her business.

      One treatment worked well for me, but sometimes another treatment may be necessary. Here are the suggested products labeled to control lawn burweed:
o Atrazine 1.5 oz. / gal. water per 1000 sq. ft.
o Weed B Gone 3 oz. / gal water per 1000 sq. ft.
o Ferti Lome Weed Free Zone 1.5 oz./ gal. water per 1000 sq. ft.
o 2,4D 1.5 oz./gal. water per 1000 sq ft.
o Bayer Advanced Southern Weed killer 2 oz. /gal. water per 1000 sq ft.
o Trimec 2 oz. /gal. water per 1000 sq. ft.
o Spectracide Weedstop 2 2oz./gal. water per 1000 sq. ft.

     These products are safe to use as labeled. If you use these or any pesticides off-label then you can expect damage. Also, these products are labeled for turf and could harm broad-leaf plants such as ornamentals, trees and shrubs.

     The “take home” lesson for the homeowners is to find lawn burweed, a winter weed, early and treat it as soon as discovered. When you or your family feel the stickers, then it is too late to treat, and you will have to wait a year for the next chance to deal with this weed.

    It is very important to treat weeds before they become a problem in your lawn. It is best to eliminate weeds before they can mature.
