In Stock

Descriptions

Sempra by Dhanuka Agritech Ltd. is India’s first herbicide based on Halosulfuron Methyl 75% WG, specifically developed for controlling Cyperus rotundus (nutgrass or motha) in sugarcane and maize crops. It is a selective, systemic, post-emergence herbicide that translocates through xylem and phloem, effectively reaching and killing underground nuts. Sempra works by inhibiting amino acid biosynthesis, resulting in yellowing, darkening, and complete destruction of the weed within 14–30 days.

Sempra is a proven, internationally registered herbicide that targets the toughest weeds like Cyperus rotundus without harming main crops like maize and sugarcane. It has been rigorously tested and recommended by leading agricultural universities across India.

Technical Content:

• Halosulfuron Methyl 75% WG

Mode of action:

SEMPRA, being a sulfonylurea group herbicide, inhibits acetolactate synthase (ALS), which is the first enzyme in the biosynthetic pathway of the essential branched chain Amino acide (Valine, Leucine & isoleucine). Inhibition of ALS leads to the starvation of the plant (Cyperus rotundus) for these amino acids, resulting in death (killing) of weeds. For crop plants, in the grass family like maize sugarcane, etc. there is no effect of Sempra as these plant have strong MFO (mixed function oxidases) which breaks down the herbicide molecule to acid metabolite forms. 

Features & Benefits:

• First herbicide in India for Cyperus control

• Kills nutgrass from both above and underground parts

• Highly selective - safe for sugarcane and maize

• Long-lasting and systemic action

• Recommended by top Indian agricultural universities

• Internationally registered (India, USA, Japan, Brazil, etc.)

Recommended Dosage:
