Dhanuka Sempra Contains Halosulfuron Methyl 75% WG which is Selective And Post Emergent Herbicide
Target Crops: It is specified for use in Sugarcane and Maize crops.
Formulation: SEMPRA is formulated as a Water Dispersible Granule (WDG), indicating its physical form for application.
Selective and Systemic: Described as a selective and systemic herbicide.
Selective implies that it targets specific types of plants (in this case, Cyperus rotundus) without affecting others.
Systemic indicates that the herbicide is absorbed and translocated within the plant, providing comprehensive control.
Mode of Action: SEMPRA is said to have strong systemic action, moving in both ways through the xylem and phloem of the plant.
It is claimed to stop the metabolic functions of Cyperus by inhibiting the formation of amino acids (Valine, Isoleucine, Leucine), essential components for protein synthesis in the plant.
This interference with amino acid synthesis is stated to result in yellowing of Cyperus leaves and darkening of nuts.
Destruction Timeframe: SEMPRA is mentioned to destroy Cyperus rotundus within 14-30 days after application.
Crop :- Sugarcane And Maize
