HPM Benister Herbicide | Bispyribac-sodium 10% SC

HPM Benister Herbicide (Bispyribac-sodium 10% SC) is a selective, systemic post-emergence herbicide widely used in direct-seeded rice. It is absorbed by both foliage and roots of weeds, making it highly effective against major grasses, sedges, and broad-leaved weeds.

The herbicide is particularly strong against Echinochloa spp. (barnyard grass), one of the most damaging weeds in rice fields. By inhibiting weed growth soon after emergence, it ensures better crop establishment and higher yields. Apart from rice, Benister is also used to stunt the growth of weeds in non-crop areas, giving farmers versatile weed management options.

By reducing competition from weeds, it improves nutrient availability and enhances crop performance. Farmers can rely on it as a cost-effective solution that reduces manual labour and maintains cleaner fields during the critical growth stages of rice.

Step-by-Step Usage Instructions

1. Wear gloves, mask, and protective clothing before mixing.
2. Mix 1 ml per litre of water (80–150 ml per acre).
3. Use 120 litres water per acre for uniform coverage.
4. Apply 15–25 DAS when weeds are at 2–4 leaf stage.
5. Avoid spray overlap on rice seedlings to prevent crop injury.
6. Do not allow drift into nearby sensitive crops.
7. Maintain a safe pre-harvest interval of 40 days.
