Description

Iodosulfuron-Methyl is a selective, systemic sulfonylurea herbicide. It matters for its high efficacy at low application rates, offering broad-spectrum control of grass and broadleaf weeds in cereal crops. This product is essential for agricultural professionals and formulators seeking advanced crop protection solutions to enhance yield and manage resistant weed populations.

Application

• Selective post-emergence herbicide for winter and spring cereals, including wheat, barley, rye, and triticale.
• Control of key grass weeds such as Alopecurus myosuroides (black-grass) and Apera spica-venti (loose silky-bent).
• Management of resistant broadleaf weeds, including Galium aparine (cleavers) and Veronica species (speedwell).
• Formulation into various commercial herbicide products, including suspension concentrates (SC) and water-dispersible granules (WG).
• Integrated weed management (IWM) programs to combat herbicide resistance.
• Use in tank mixes with other herbicides for broader spectrum control and resistance management.
