Mode of Action

Sempra belongs to the sulfonylurea group of herbicides and functions by inhibiting the enzyme acetolactate synthase (ALS). This inhibition disrupts the biosynthesis of essential branched-chain amino acids (valine, leucine, and isoleucine), leading to the starvation and eventual death of the target weed. Its systemic nature allows it to move both upward and downward within the plant through the xylem and phloem, ensuring comprehensive control of Cyperus rotundus.

Key Features & Benefits

• Low Dosage Requirement: Effective control at just 36 grams per acre, reducing chemical usage.

• Rapid Action: Inhibits nutrient uptake by Cyperus rotundus within 24 hours, leading to weed suppression.

• Crop Safety: Specifically targets nutsedge without harming sugarcane and maize crops.

• Residual Activity: Provides soil residual action, controlling late-emerging weeds and reducing the need for repeated applications.

• Cost-Effective: Reduces manual weeding expenses and enhances crop yield, leading to increased profitability.
