МЕТОЛАХЛОР

Химические свойства

Metolachlor is a colorless or tan to brown, oily liquid. Slightly sweet odor.

Использование

A selective pre-emergence herbicide.

Общее описание

Tan to brown oily liquid with a slightly sweet odor. Slightly soluble in water and denser than water. Hence sinks in water. Soluble in most organic solvents. Used as a selective herbicide.

Реакции воздуха и воды

Slightly soluble in water. Hydrolyzed by strong mineral acids and strong alkalis.

Профиль реактивности

Metolachlor is a chlorinated acetamide. May react with azo and diazo compounds to generate toxic gases. May form flammable gases with strong reducing agents. Combustion generates mixed oxides of nitrogen (NOx).

Угроза здоровью

Can cause skin irritation and eye irritation. Headache and nausea may occur following prolong exposure.

Сельскохозяйственное использование

Herbicide: Not approved for use in EU countries. Registered for use in the U.S. Metolachlor is a selective herbicide that is usually applied to crops before plants emerge from the soil, and is used to control certain broadleaf and annual grassy weeds in field corn, soybeans, peanuts, grain sorghum, potatoes, pod crops, cotton, safflower, stone fruits, nut trees, highway rights-of-way and woody ornamentals. Prior to the RED of April, 1995, its primary use was on corn, soybeans and sorghum. It inhibits protein synthesis; thus, high-protein crops (e. g., soy) can be adversely affected by excessive metolachlor application. Additives may be included in product formulations to help protect sensitive crops (i.e., sorghum) from injury.

Metolachlor is a chlorinated acetamide selective herbicide used for weed control in corn and for controlling grasses in a variety of crops including cotton and peanuts.

Метаболический путь

A stable bacterial community absorbs and transforms metolachlor from a liquid medium. From the medium of the 7 day-old culture of the bacterial community, 2- hydroxy-N-(2-methyl-6-vinylphenyl)-N-(2-methoxy- methylethyl)acetamide and 4-(2-ethyl-6-methylphenyl)- 5-methyl-3-morpholinone are identified. The products recovered from cells of J4-A include dechlorinated metolachlor, a thiol compound, a more complicated conjugate, and a non-sulfur-containing conjugate. By sorghum microsomes, O-demethylation occurs in the metolachlor degradation process.

Несовместимости

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, nitrates. Compounds of the carboxyl group react with all bases, both inorganic and organic (i.e., amines) releasing substantial heat, water and a salt that may be harmful. Incompatible with arsenic compounds (releases hydrogen cyanide gas), diazo compounds, dithiocarbamates, isocyanates, mercaptans, nitrides, and sulfides (releasing heat, toxic, and possibly flammable gases), thiosulfates and dithionites (releasing hydrogen sulfate and oxides of sulfur).

Утилизация отходов

In accordance with 40CFR 165 recommendations for the disposal of pesticides and pesticide containers. Must be disposed properly by following package label directions or by contacting your local or federal environmental control agency, or by contacting your regional EPA office.
