What is BUTRALIN?
Chemical properties
Butralin is a yelloworange crystalline solid or liquid. Commercial product is available as an emulsifiable concentrate.
The Uses of BUTRALIN
Herbicide.
Definition
ChEBI: Butralin is a C-nitro compound.
Agricultural Uses
Herbicide; plant growth regulator: Not approved for use in EU countries. Actively registered for use in the U.S. Butralin is used as a plant growth regulator on tobacco after the tobacco is topped. All tobacco is topped to stimulate desirable chemical and physical characteristics but it also stimulates the growth of suckers. All uses on food crops were canceled in January, 1991, and all uses on turf and ornamental grasses were voluntarily canceled in March, 1997. It may be used on food crops, broadleaf weeds and ornamentals in some countries. Butralin has been found effective in destroying opium poppy crops.

Incompatibilities
Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides
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 andnonrecyclable 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.
