The 411 on Eco-Friendly Weed Control

By Barry Draycott


One of the biggest problems facing lawn care companies is weed control.  It is even more daunting when trying to do so in an environmentally friendly way. We all know that the first line of defense against weeds it to develop a thick healthy lawn which will crowd out most weeds. However, weeds will still appear and customers will complain. Until now, the only effective means of selectively controlling weeds has been chemical herbicides.


 

That all changed in 2012 when a new product named ADIOS, manufactured in Canada by Herbanatur, was permitted for use in the US. ADIOS is approved for organic use by the Organic Materials Review Institute (OMRI) and is exempt from EPA Registration under FIFRA 25(b).

 

Unlike other organic weed control products, ADIOS is a systemic, selective post emergent foliar herbicide for the control of many broadleaf and grassy weeds. Rather than just burning down top growth, the active ingredient translocate into the root for a more effective kill. And six years of research has resulted in ADIOS being able to control broadleaf and grassy weeds without damaging turf grass.

 

In addition, ADIOS is also effective in controlling poison ivy, giant hogweed and Japanese knotweed. It is a non-toxic and odorless selective weed killer that can be safely used on turf & lawn or around ornamental plants, bushes, small trees, fruits and vegetables gardens. No buffer zone is required next to drinkable fresh water wells or wetlands.

 

Samples were sent to about a dozen lawn care operators in the mid-west and northeastern states for trialing. Almost all reported satisfactory control of labeled weeds with one or two applications.

 

A research professor at Ohio State University initiated a trial using ADIOS on November 26, 2012.  Temperature at the time of application was about 45 degrees (so cooler than the label states). View Label. A follow up application was also performed.  At 21 days after the initial application, we observed 100% control of dandelion, white clover, and ground ivy. Rapid burn down and control was observed.  Follow up work will be performed to see what weed recovery is like in the spring and/or conduct additional trials on turf phytotoxicity or to see if a repeated application program can result in permanent control.

Given that the application was performed in less than ideal circumstances due to the late timing, the results were impressive.

 

Beginning this spring ADIOS will be available for shipment in the Northeastern and Midwestern states. Because ADIOS is EPA Exempt, a pesticide license is not required in some States. There is no other organic product on the market that will perform as well as ADIOS and is cost effective. This is a great new tool that is perfect for sensitive areas such as school yards, playgrounds, parks, health care centers, near wetlands and other clients who are more comfortable with fewer chemical applications.

 

With public demand for safer products growing and stricter pesticide regulations on the horizon, the timing couldn’t be better than now to add ADIOS to your weed control program.
