Usage

Chemical Properties

Yellow-orange crystalline solid. Mild amine odor. Commercial products and mixtures may contain flammable carriers (such as xylene); these may be red-orange liquids with a mild aromatic odor.

Agricultural Uses

Herbicide: Ethalfluralin is a selective herbicide used for the pre-emergence control of annual grasses and broadleaf weeds in certain food and feed crops. Ethalfluralin may be used in growing a variety of grain, seed, and cucurbit crops. The greatest amounts of ethalfluralin are used in growing soybeans, dry beans, and sunflower seeds. Ethalfluralin is used only outdoors, in agriculture; no residential uses were registered. Not used in EU countries. Registered for use in the U.S.

UN3082 Environmentally hazardous substances, liquid, n.o.s., Hazard class: 9; Labels: 9- Miscellaneous hazardous material, Technical Name Required. UN3077 Environmentally hazardous substances, solid, n.o.s., Hazard class: 9; Labels: 9-Miscellaneous hazardous material, Technical Name Required

Incompatibilities

Sensitive to heat. Dintroanilines can be explosive and are strong oxidizers. Contact with reducing agents, other strong oxidizers or, nitrosylsulfuric acid may cause fire or explosion

Waste Disposal

Do not discharge into drains or sewers. Dispose of waste material as hazardous waste using a licensed disposal contractor to an approved landfill. Contact a licensed disposal facility about surplus and nonrecyclable solutions. Burn in a chemical incinerator equipped with an afterburner and scrubber. Extra care must be exercised as the material in an organic solvent is highly flammable. Consult with environmental regulatory agencies for guidance on acceptable disposal practices. Incineration with effluent gas scrubbing is recommended. 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. Do not reuse container
