Description

Linuron (CAS 330-55-2) is a selective phenylurea herbicide used in crop protection to control a broad spectrum of annual grasses and broadleaf weeds. It acts by inhibiting photosynthesis in target plants. This chemical serves as a post-emergence and pre-emergence treatment option across multiple field crops. It is applied in soybean, corn, potato, carrot, and cereal crop production to suppress weed competition.

During critical early growth stages, it controls problem weeds such as chickweed, pigweed, and lambsquarters. It does so without damaging established crops when applied at label-specified rates for vegetable cultivation. Formulators incorporate it as the active ingredient in wettable powder and suspension concentrate herbicide products. These are sold through agricultural distribution channels for professional use in the field.

It is also used in non-crop settings such as industrial land management and rights-of-way vegetation control. This versatility makes it a staple in large-scale weed management programs globally. The product is supplied as a technical-grade active ingredient, typically as a crystalline powder. It features defined purity specifications meeting rigorous agrochemical manufacturing standards for quality and consistency.

Formulated products are available as wettable powders and suspension concentrates for end-use application. Procurement is standard through agrochemical active ingredient suppliers for bulk industrial needs. Technical grade remains the primary form traded at the bulk level for global distribution. This ensures that manufacturers receive a high-purity material suitable for various agricultural formulations and blends.
