Frequently asked questions
What is Corsican?
Corsican is a selective residual preemergence herbicide for controlling most annual grass weeds, annual broadleaf weeds, and sedges. It provides contact burndown of many broadleaf weeds when applied with an adjuvant. It is a non-HPPD herbicide that helps stop HPPD-resistant weeds.
What are the active ingredients in Corsican?
Corsican contains two active ingredients: Saflufenacil and Dimethenamid-P.
What crops can Corsican be applied to?
Corsican is labeled for use on Field Corn (Grain, Seed, Silage), Popcorn, Processing Sweet corn, Grain Sorghum, and Soybeans. Always consult the label for specific varieties and restrictions.
What weeds does Corsican control?
Corsican provides residual preemergence control or suppression of various annual grasses, broadleaf weeds, and sedges. It also provides burndown control of broadleaf weeds. For postemergence (burndown) control, apply before weeds exceed the listed maximum sizes. Use tank mixes for broader spectrum or larger weeds. Key weeds include:

When and how should Corsican be applied?
Corsican can be applied preplant (burndown) and preemergence. Rates vary by soil texture and organic matter. See label for specific rate guidance. For burndown, add MSO. Do not apply through irrigation systems. Follow crop-specific timings and tank mix with other herbicides for full spectrum control.
