Q: Why can’t I use lawn weed killers to clean up my pond’s shoreline?
Kevin – Heath, OH
A: If you read the fine print on your favorite lawn weed killer and your favorite aquatic shoreline weed killer, you’ll notice that they both contain the same active ingredient—glyphosate. This broad-spectrum herbicide works wonders in destroying actively growing foliage. In fact, it’s one of the most popular weed destroyers out there.
Just because the lawn weed killer and shoreline weed killer have the same active ingredient, however, doesn’t mean you can use them interchangeably. You see, the inert or inactive ingredients used in the formulas are different. Those different ingredients make the shoreline chemicals safe around bodies of water and lawn chemicals unsafe around bodies of water.
By law, these differences and designated uses must be noted on the herbicide’s label. The Environmental Protection Agency approves the label and warns consumers of any dangers. In fact, if you continue to read that fine print on your lawn weed killer’s label, you’ll find it says to not apply the product on or around water sources.
If you’re treating weeds around your pond or lake, be sure to use one that has been approved for use around water bodies, like Shoreline Defense® and Treatment Booster™ PLUS. When applied directly to the foliage, the aquatic herbicide safely destroys a range of weeds and grasses—including cattails—on the shoreline, beach or anywhere emergent weeds grow.
Like it or not, you should read your labels and use the right formula for the job. You’ll be keeping your water supply safe, the government happy and your land legal.
