No middleman ensures best quality at wholesale prices.
Gamma Paraquat Dichloride 24% SL is a non-selective contact herbicide from the bipyridylium chemical group, widely trusted by Indian farmers for effective weed management. It works by disrupting photosynthesis in green plant tissues, causing rapid leaf desiccation. Once applied, weeds show visible burn-down within 24–48 hours.
Gamma is ideal for use in rice, wheat, sugarcane, cotton, potato, and coffee, providing pre-planting, pre-sowing, and post-emergence weed control. It is also effective for managing weeds in tea, maize, grapes, apple orchards, waterways, and aquatic systems. With flexible pack sizes (5 L, 1 L, 500 ml, 250 ml), Gamma offers affordable solutions for farms of all scales.
Farmers rely on Gamma to reduce weed competition, conserve soil nutrients, and improve crop productivity. To explore more weed control options, visit our herbicide collection page. For authoritative guidelines, see ICAR’s Integrated Weed Management.
