DESCRIPTION
PI Londax Power Bensulfuron Methyl 0.6% + Pretilachlor 6% GR Herbicide Details :
- Pi Londax Power is a pre-emergence granular herbicide formulated with Bensulfuron Methyl 0.6% + Pretilachlor 6% GR for selective and effective weed control in transplanted rice. It targets major grasses, sedges, and broadleaf weeds, inhibiting growth at early stages. The dual mode of action-Acetolactate Synthase inhibition and very-long-chain fatty acid synthesis inhibition-ensures broad-spectrum control. Easy to apply by hand broadcasting in the rice puddle, it offers crop safety and long-lasting weed suppression.

FAQs – PI Londax Power (Bensulfuron-Methyl + Pretilachlor WG)
1. What is Londax Power used for and what does it control?
Ans. Londax Power is a selective post-emergence herbicide designed specifically for transplanted rice. It effectively controls a broad range of weeds, including grasses, sedges, and broadleaf weeds such as Echinochloa spp., Cyperus spp., Eclipta, and Ludwigia species.
2. How does the combination of Bensulfuron-Methyl and Pretilachlor work?
Ans.
- Pretilachlor functions pre-emergently, targeting weed seeds and early germination stages.
- Bensulfuron-Methyl is systemic and inhibits the ALS enzyme, halting cell division in established weeds.
- Together, they provide effective control from early stages through plant growth.
3. How much quantity is recommended and how is it applied?
Ans.
- The standard dosage is 10 kg per hectare (≈4 kg per acre). It's in a granular form, which should be mixed with sand or fertilizer and broadcast across puddled rice fields.
- A practical application from ICAR NRRI recommends mixing with sand and applying 4 kg per acre, 5–8 days after transplanting.
4. Can Londax Power be applied both pre- and post-emergence?
Ans. Yes—while primarily used post-emergence in transplanted rice, its formulation allows flexibility for early application to control weeds during germination and beyond.
5. How effective is it in controlling weeds and improving yield?
Ans. Field studies have shown over 80% weed control efficiency for species like barnyard grass and sedges, with yields reaching 5.5 t/ha, comparable to manual weeding.
6. Is Londax Power safe for rice crops?
Ans. Yes—Londax Power is highly selective for rice, with a wide safety margin (5–30x) when used at recommended rates.
