FAQ for Ratna Sipra
Which weeds does Ratna Sipra control?
Ratna Sipra specifically controls Cyperus rotundus (purple nutsedge) and Cyperus iria — two of the most difficult-to-control sedge weeds that cause significant yield losses in sugarcane, maize, and bottle gourd.
How does Halosulfuron Methyl work?
Halosulfuron Methyl inhibits ALS enzyme disrupting branched-chain amino acid biosynthesis in susceptible Cyperus species, causing slow systemic death that extends to connected tubers and rhizomes.
Is Ratna Sipra effective against nutsedge tubers?
Yes, Halosulfuron Methyl in Ratna Sipra has systemic activity that translocates through connected nutsedge tuber chains, providing more thorough suppression of Cyperus rotundus than contact-only herbicides.
When should Ratna Sipra be applied in sugarcane?
Apply Ratna Sipra post-emergence in sugarcane when nutsedge plants are small and actively growing with 3–6 leaves. Use sufficient water volume for thorough coverage of sedge plants.
What is the recommended dosage of Ratna Sipra?
Ratna Sipra is available in 3.6g and 36g packs and is used at very low rates due to its 75% WG high concentration. Follow label recommendations precisely for crop-specific dosage guidance.
