What is s metolachlor?

Metolachlor or S-metolachlor is a selective and systemic herbicide which control weeds by inhibiting the synthesis of long chain fatty acids.

What is the difference between S metolachlor and metolachlor?

S-metolachlor has more weed control activity pound-for-pound than metolachlor. Metolachlor is comprised of two isomer pairs, an S-isomer pair and an R-isomer pair at a 1:1 ratio (50% each). Generic metolachlor herbicide brands contain only the racemic (1:1 ratio) metolachlor.

How is metolachlor used in the United States?

Metolachlor is a popular herbicide in the United States. As originally formulated metolachlor was applied as a racemate, a 1:1 mixture of the ( S )- and ( R )-stereoisomers. The ( R )-enantiomer is less active, and modern production methods afford a higher concentration of S-metolachlor, thus current application rates are far lower…

Which is the enantiomer of R-metolachlor?

S-Metolachlor. More… (S)-metolachlor is the (S)-enantiomer of 2-chloro-N- (2-ethyl-6-methylphenyl)-N- (1-methoxypropan-2-yl)acetamide. It is an enantiomer of a (R)- metolachlor.
