Nicosulfuron 40g/L OD Selective Maize Herbicide Sulfonylurea Weed Control

Nicosulfuron controls weeds by inhibiting acetolactate synthase (ALS), an enzyme essential for producing branched-chain amino acids. This disruption halts protein biosynthesis, leading to plant death in susceptible weeds.

The herbicide is rapidly absorbed by leaf tissue and translocated to meristems via both phloem and xylem systems. This systemic action reaches actively growing points throughout the weed, causing chlorosis, necrosis, and complete plant death within 10-14 days of application.

Corn's tolerance to nicosulfuron stems from its ability to rapidly metabolize the herbicide into inactive compounds through glutathione S-transferase enzymes. This detoxification mechanism allows corn to survive while susceptible weeds perish.

Nicosulfuron delivers effective control of annual grass weeds, broadleaved weeds, and perennial grasses including Johnsongrass and Elymus repens. Optimal performance is achieved when applied at the 2-4 leaf weed stage.

As an ALS inhibitor, nicosulfuron is prone to resistance development with repeated use. Research indicates resistance can emerge after as few as 10 consecutive applications. To prevent resistance:

• Rotate with herbicides from different mode-of-action groups
• Consider tank-mixing with Group 15, 14, or 9 herbicides
• Implement integrated weed management strategies
• Always use full labeled rates and proper timing

Timing: Apply at post-emergence when target weeds are at 2-4 leaf stage for optimal efficacy.

Tank-Mix Partners: Commonly combined with atrazine, acetochlor, or metribuzin to broaden weed spectrum and combat resistant biotypes.

Sprayer Cleanout: Thoroughly rinse sprayers after use to prevent carryover injury to sensitive crops.

Always follow product label instructions and local regulatory requirements for exact dosage rates and application guidelines.

It is strictly a post-emergence, foliar-applied herbicide that requires weeds to have emerged to be effective.

Yes, it can be applied to sweet corn at 20-30 g a.i./ha during early post-emergence when weeds are at 2-4 leaf stage.

ALS inhibitors are prone to resistance development, which has been documented in dozens of grass weed species globally.

No, it is selective for corn and can cause significant injury to sensitive crops like sorghum.
