Sempra Herbicide Uses, Price, Technical Name, Dose & Complete Information

For efficient management of Cyperus rotundus, Dhanuka Agritech Ltd. released Sempra Herbicide as the first herbicide in India. In order to effectively control Cyperus rotundus from nuts in Sugarcane and Maize crop, it is a selective, systemic, post-emergence herbicide with WDG formulation. Sempra Herbicide goes both ways through the Xylem and Phloem and has a strong systemic impact.


In this article you’ll find information about the following:

Technical content:

Halosulfuron Methyl 75%wgx


Mode of action:

Excellent foliar treatment efficacy for Cyperus rotundus and Cyperus iria in maize and bottle gourd crops is provided by halosulfuron methyl 75% WG.

It enters the space through the xylem and travels through the phloem to travel downhill. It builds up in the plant and prevents aceto-lactate synthase (ALS), an enzyme that is in charge of acquiring necessary amino acids, from doing its job. Since they are unable to maintain proteins for new cells, the impacted weeds. Water usage by the plant (transpiration) is what powers the entire process.


Dosage of Sempra herbicide according to crops.


Crop(S) Common Name of Weeds Dosage/HA

ai(gm).                     Formulation(ml)

Dilution in water(Litre)
Sugarcane Cyperus rotundus L 60-67.5 80-90 375
Maize Cyperus rotundus L, Cyperus iria L 67.5 50 375
Bottle Gourd Cyperus rotundus L, Cyperus iria L 67.5 90 375


Sempra herbicide uses:

  • Effectiveness at Low Dose: At 36 gm/acre, Sempra offers excellent control of Cyperus rotundus. Additionally, it promotes soil residual activity and eliminates late-emerging weeds. Its dosage is modest in comparison to more conventional herbicides.
  • Checked for nutrient uptake: Sempra monitors Cyperus rotundus’ nutrient uptake 24 hours after application, resulting in a good, healthy crop.
  • The crops of sugarcane and maize are unaffected by Sempra.
  • Sempra has a powerful residual effect in the soil, which allows it to control newly sprouting Cyperus rotundus.
  • Reduced Weeding Costs: Sempra frees users from having to repeatedly weed by hand, which reduces the expense of applying herbicides manually and thereby reduces weeding costs.
  • Sempra increases yield, which leads to higher earnings.


Why is weed controlled using herbicides?

Even in instances when manual and mechanical approaches cannot be used, herbicides have a very high level of weed control. In damp soil, for instance, weeding by hand or machine is put off, but weed control with herbicides could be accomplished. Herbicide cuts down on weed control’s expense and labor-intensiveness. According to reports, manual weed treatment is far more expensive than herbicidal weed control and provides three to four times as much net benefit. In contrast to manual and mechanical weed management, herbicide-based weed control has definite economic advantages.




1.What is Cyperus rotundus?

Ans. One of the most invasive weeds is Cyperus rotundus, which has established a global distribution in both tropical and temperate climates. Given that it is considered a weed in more than 90 countries and infests more than 50 crops globally, it has been dubbed “the world’s worst weed”.


2. Why it is important to eliminate Cyperus rotundus?

Ans. Cyperus rotundus needs to be eradicated because it is an aggressive competitor for soil resources and because it is allelopathic, meaning that the roots release chemicals that are damaging to other plants, its presence in a field drastically affects crop production.Similar to that, it also negatively affects planting for adornment
