Descriptions

It is a selective, systemic, post-emergence herbicide with WDG formulation for effective control of Cyperus rotundus from nuts in Sugarcane and Maize crop. SEMPRA has strong systemic action i.e. moves in both ways through Xylem & Phloem.

SEMPRA stops the metabolic functions of the Cyperus by stopping the formation of the amino acids (Valin, Isoleucine, Lucine) which is responsible for the protein required for the growth of the Cyperus resulting in the yellowing of its leaves & nuts becoming darker & further destroying it in 14-30 days.

Sempra Herbicide contains Halosulfuron methyl 75%wg and is a selective early post-emergence herbicide for control of yellow nutsedge and purple nutsedges and certain broadleaf weeds in barley, wheat, maize, and sugarcane.

Mode of Action: Taken up through the roots and shoots, upwards via the xylem, and downwards via the phloem. It accumulates in the plant and inhibits the plant enzyme acetolactate synthase (ALS) which is responsible for purchasing essential amino acids. The affected weeds cannot, therefore, maintain proteins for new cells. The whole process is driven by the plant's use of water (transpiration).

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 acids (Valine, Leucine & isoleucine). Inhibition of ALS leads to the starvation of the plant (Cyperus rotundus) for these amino acids, resulting in the death (killing) of weeds. For crop plants, in the grass family like maize sugarcane, etc. there is no effect of Sempra as these plants have strong MFO (mixed function oxidases which break down the herbicide molecule to acid metabolite forms. 

Target Pest/ Disease : 

• Efficacy at Low Dose: Sempra provides outstanding control of Cyperus rotundus at 36 gm/acre. It also offers soil residual activity and controls late-emerging weeds. Compared to traditional herbicides its dosage is low.

• Nutrient uptake checked: Sempra checks nutrient uptake by Cyperus Rotundus within 24 hrs of application resulting in a good healthy crop.

• Safe to Crop: Sempra does not harm the crop of Sugarcane & Maize.

• Strong Soil Residual Action: Sempra has strong residual action due to which it controls new germinating Cyperus rotundus.

• Reduced Weeding Expenses: Sempra gives freedom from repeated manual weeding which leads to saving manual labor costs in herbicide application.

• Increase Yield: Sempra results in more yield hence more profits.
