Uses

Metobromuron is a preemergence herbicide.

Definition

ChEBI: Metobromuron is a member of ureas.

Agricultural Uses

Herbicide: Pre-emergence herbicide. Used against grasses and broadleaf weed control on flax, groundnuts, potatoes, beans, soybeans, sunflowers, tomatoes, and tobacco. Pending for use in EU countries. Not registered for use in the U.S. There are 24 global suppliers.

Trade name

C-3126®; CIBA 3126®; PATORAN®; PATTONEX®

Safety Profile

Moderately toxic by ingestion and intraperitoneal routes. An eye irritant. When heated to decomposition it emits toxic fumes of Brí and NOx

Potential Exposure

Preemergence substituted urea herbicide used to control grasses and broadleaf weeds on flax, groundnuts, potatoes, beans, soybeans, sunflowers, tomatoes, and tobacco.

Shipping

UN3021 Pesticides, liquid, flammable, toxic, flash point ,23 C, Hazard Class: 3; Labels: 3-Flammable liquid, 6.1-Poisonous materials. Technical Name Required. UN2767 Phenyl urea pesticides, solid, toxic, Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required.

Incompatibilities

This organic bromine compound may react with strong oxidizers such as chlorates, peroxides, nitrates, permanganates, perchlorates, chlorine, fluorine, etc. Keep away from strong acids.

Waste Disposal

Hydrolysis is not recommended as a disposal procedure because of the generation of the toxic products, 3,4-dichloroaniline and dimethylamine. Incinerate in a unit with effluent gas scrubbing. Containers must be disposed of properly by following package label directions or by contacting your local or federal environmental control agency, or by contacting your regional EPA office.
