Common Product Names: Resource 

What is it?

Flumiclorac is a selective herbicide used for controlling broadleaf weeds. Its action is rapid, often resulting in visible damage to weeds within hours of application. As a post-emergent herbicide, it is most effective when applied to actively growing weeds. Flumiclorac is typically used in tank mixes with other herbicides to broaden its spectrum of control and to manage resistant weed populations.

How does it work?

Once Flumiclorac is applied to the target weeds, it is absorbed through the leaves and begins to inhibit the PPO enzyme. The inhibition leads to the buildup of toxic compounds within the weed's cells, causing rapid cell membrane breakdown. This results in visible symptoms such as leaf wilting, browning, and eventual weed death. The herbicide's action is rapid, with results often visible within a few hours to a day, making it a fast-acting solution for weed management.

Benefits

• Rapid Action: Visible effects on weeds can be seen within hours of application, allowing for quick assessment of effectiveness.
• Selective Control: Specifically targets broadleaf weeds without harming most grasses, making it suitable for use in crop systems like soybeans, cotton, and corn.
• Post-Emergent Application: Effective against weeds that have already emerged, making it a valuable tool in mid-season weed management.
