Clopyralid® Notice

The broadleaf herbicide Clopyralid® (Pronounced: Clo-PEER-uh-lid and manufactured by Dow AgroSciences-LLC) has been found to be extremely persistent. Clopyralid is an active ingredient in more than a dozen herbicides. Some of the retail names for these products are Confront®, Millennium®, Stinger®, Reclaim®, Lontrel® and Transline®. Most products with Clopyralid are limited to the professional lawn care industry or agricultural uses.

This herbicide is so persistent that many compost operations are unable to break it down adequately. Caution is advised when applying compost from unknown sources to sensitive broadleaf plants (includes many garden vegetables and annual flowers). OmaGro is tested for the presence of Clopyralid and to date it has not been identified as a problem. OmaGro's long composting times (in excess of 15 months) and feedstock limited to residential lawns have limited OmaGro's exposure to Clopyralid. It is always the best advice to read, understand and follow label directions. Doing so with OmaGro will further protect your lawn and garden.

Many commercial-only herbicide blends contain high concentrations of Clopyralid. Grass clippings from lawns treated with these brands are the major source of Clopyralid contamination for yardwaste composting operations.

You can help by ensuring that your lawn service provider uses an herbicide that is Clopyralid-free. There are effective alternatives to Clopyralid that do not have the same residual affects. If found in an existing consumer product, at a minimum follow the label directions exactly and do not over apply. Additionally Douglas and Sarpy County residents may dispose of Clopyralid containing products at UnderTheSink (, the two county facility for disposing of household chemicals. According to the Environmental Protection Agency (EPA) Clopyralid is not harmful to humans or animals at the levels detected in compost.
