As pest control professionals we are often expected to eradicate any and every dollar weed in a customer’s lawn with just a single weed control application. The trouble with that is there are several major factors that affect dollar weed control in St. Augustine turf and many of these factors are outside of our control.

The single biggest factor is often water. Dollar weed is an aquatic weed meaning it thrives where there is an abundance of water. This could be due to several factors, including poor drainage, shade, soil compaction, and excessive irrigation. That’s why we work with our customers to fine tune their irrigation systems and practices to insure that all water related factors are being addressed.

Another common factor influencing dollar weed control is the invasion of dollar weed from neighboring lawns.  We understand that you have no control over your neighbors weed control issues so all of our technicians are trained to concentrate on the perimeters and borders of our customers’ lawns when making pre emergent weed control applications.

The final factor in dollar weed control is the application of post emergent herbicides. Many of the products that are commonly used for weed control are not particularly effective on dollar weed. The most glaring example of this is the herbicide Atrazine. Long considered the only herbicide needed for weed control in St. Augustine turf, Atrazine does a poor job at best of controlling dollar weed. Because it is the primary weed control product in “Weed and Feed” type fertilizers many homeowners are left with yards full of dollar weed. And ever since its 2003 EPA mandated label change it can’t be legally applied within 66 feet of perennial or intermittent streams and rivers or within 200 feet around natural or impounded lakes and reservoirs (including retention ponds). How many landscapes in your neighborhood does that rule out?

Our solution to the dollar weed problem is the use of a blend of properly labeled herbicides that are more effective in the control of dollar weed as well as other broadleaf weeds. With our specialized herbicide blends dollar weed is generally one of the easiest weeds for us to control. As a matter of fact we guarantee at least 50% control of it with your initial application alone.
