FrontRunner

Frequently Asked Questions

• What is FrontRunner herbicide and what active ingredient does it use?

  FrontRunner by Atticus LLC is a dry flowable agricultural herbicide labeled for broadleaf weed control in soybeans; its active ingredient is cloransulam‑methyl (equivalent to FirstRate®) at 84% technical (0.84 lb ai per lb product), EPA Reg. No. 91234‑84. It’s labeled for control of many glyphosate‑tolerant broadleaf weeds and is listed as rotatable with crops such as corn, alfalfa and wheat.
• When and how should I apply FrontRunner in soybean fields?

  FrontRunner offers flexible use timing — it can be applied preplant incorporated (PPI), preplant surface, preemergence, or postemergence — and is tank‑mixable with glyphosate for broader spectrum control. As a dry flowable, follow label mixing instructions, use agitation during mixing, apply mixtures immediately (do not store), and clean application equipment thoroughly after use.
• How does FrontRunner compare to FirstRate and other cloransulam‑methyl products?

  FrontRunner contains the same active ingredient, cloransulam‑methyl, as FirstRate and provides a comparable spectrum of pre‑ and postemergence broadleaf control in soybeans. Because formulations and labeling (rates, tank‑mix partners, use restrictions) can differ, always compare the specific product labels before choosing between products.
• Which weeds does FrontRunner control and how should it be used in resistance management?

  FrontRunner controls many broadleaf species including common ragweed, marestail (horseweed), lambsquarters, morning glory, sunflower, velvet leaf and various pigweeds when used as labeled. For resistance management, rotate herbicide modes of action, employ labeled tank‑mix partners (for example glyphosate where appropriate), and avoid repeated sole reliance on cloransulam‑methyl across seasons.
• What safety, environmental and mixing precautions are required when using FrontRunner?

  Follow label PPE requirements such as coveralls, chemical‑resistant gloves, and shoes plus socks; use closed blenders for fertilizer blends, agitate dry/flowable formulations during mixing, and apply mixtures immediately without storage. FrontRunner has a high potential for surface‑water and sediment contamination on poorly drained soils, so maintain vegetative buffers, prevent runoff, and clean equipment thoroughly after use.
