化学的特性
Metolachlor is a colorless or tan to brown, oily
liquid. Slightly sweet odor.
使用
A selective pre-emergence herbicide.
一般的な説明
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.
空気と水の反応
Slightly soluble in water. Hydrolyzed by strong mineral acids and strong alkalis.
反応プロフィール
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).
健康ハザード
Can cause skin irritation and eye irritation. Headache and nausea may occur following prolong exposure.
农业用途
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.

職業ばく露
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.
代謝経路
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.

UN2902 Pesticides, liquid, toxic, n.o.s., Hazard
Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name
Required. UN3082 Environmentally hazardous substances,

不和合性
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).
廃棄物の処理
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.
