A new product for homeowners has appeared on the market that is called “Roundup” but it does not contain glyphosate which is the active ingredient that most people associate with “Roundup”. Although this is not an agricultural issue, it points out the need to always read the label to verify what you are spraying. Commercial names can be misleading. This new product is called “Roundup for Lawns” and it contains MCPA, Quinclorac, Dicamba and Suldentrazone. It does not contain Glyphosate. Marketing this product as “Roundup”(Glyphosate), even though it does not contain “Roundup” (Glyphosate), will confuse many people. Glyphosate is sold under many commercial names, including Roundup, and is typically non-selective and kills both grass and broadleaf plants. It also has no soil activity and is not volatile. The active ingredients for “Roundup for Lawns” include a couple growth regulators that can be volatile and injure nearby broadleaf vegetation. It also contains a couple ingredients that can have some soil activity.
