About the Product

Sempra Herbicide is a selective, systemic, post-emergence herbicide developed by Dhanuka Agritech Ltd. It is formulated specifically to control Cyperus rotundus (commonly known as nutsedge) in sugarcane and maize crops. Sempra ensures fast suppression and long-lasting control, offering a reliable and sustainable weed management solution for farmers.

Technical Details

• Technical Name: Halosulfuron Methyl 75% WG

• Mode of Entry: Systemic

• Mode of Action: Sempra belongs to the sulfonylurea group and inhibits acetolactate synthase (ALS), the first enzyme in the biosynthetic pathway of essential branched-chain amino acids (Valine, Leucine, Isoleucine). This inhibition leads to nutrient starvation in weeds like Cyperus rotundus, causing their death. It is safe for sugarcane and maize due to rapid breakdown by plant enzymes.

Key Features & Benefits

• Low Dose, High Efficiency: Controls Cyperus rotundus effectively at only 36 gm/acre

• Stops Nutrient Uptake in Weeds: Begins action within 24 hours

• Safe for Crops: Sugarcane and maize remain unaffected

• Strong Residual Control: Prevents regrowth by affecting new germinating weeds

• Reduces Manual Labor: Eliminates the need for frequent hand weeding

• Higher Crop Yield: Better weed management results in healthier crops and more profits
