Usage

Uses

Used in Agricultural Industry:
Ethalfluralin is used as a selective herbicide for the pre-emergence control of annual grasses and broadleaf weeds in certain food and feed crops. It is particularly effective in growing a variety of grain, seed, and cucurbit crops, with the greatest amounts being used in soybeans, dry beans, and sunflower seeds. Ethalfluralin is used exclusively outdoors in agricultural settings, with no residential uses registered. It is not used in EU countries but is registered for use in the U.S.

Potential Exposure

Ethalfluralin is a 2,6-fluorodinitrotoluidine 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

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

Synergistic herbicidal compositions comprising 4-benzoylisoxazole and dinitroaniline herbicides

The invention relates to synergistic compositions comprising: (a) a 4-benzoylisoxazole of formula (I) STR1 wherein R, R1, R2 and n are as defined in the specification; and (b) a dinitroaniline herbicide; and to the use of these compounds as herbicides.

Process for preparing ethalfluralin

A process for the preparation of the unsaturated dinitroaniline, ethalfluralin having a level of nitrosamines lower than 0.5 ppm and essentially free from the compound of addition of halogenhydric acid on the methallyl double bond, by treatment with aqueous halogenhydric acid, wherein crude ethalfluralin is treated under agitation with an aqueous solution of hydrobromic acid in the presence of sulfamic acid and a sulfur compound selected from the group consisting of bisulfites, metabisulfites, hydrosulfites, sulfurous acid and gaseous sulfur dioxide.

Substituted pyridinesulfonamide compounds or their salts, process for preparing the same, and herbicides containing the same

A substituted pyridinesulfonamide compound or its salt represented by the following general formula (I): wherein R1 is an unsubstituted or substituted alkyl group; R2 is an unsubstituted or substituted alkyl group, or an unsubstituted or substituted alkoxy group; and X and Y are each independently a member selected from the group consisting of alkyl groups and alkoxy groups, is disclosed. This compound is useful as the effective ingredient of a herbicide showing a wide weed-control spectrum even if used in a small amount.
