S-metolachlor NOMENCLATURE
Common identify S-métolachlore ((m) F-ISO) S-metolachlor (BSI, E-ISO) 
IUPAC name A mixture of (aRS,1S)-2-chloro-6′-ethyl-N-(two-methoxy-one-methylethyl)aceto-o-toluidide and (aRS,1R)-2-chloro-6′-ethyl-N-(two-methoxy-1-methylethyl)aceto-o-toluidide in the proportion eighty-one hundred% to twenty-%
Chemical Abstracts name A mixture of (S)-two-chloro-N-(2-ethyl-six-methylphenyl)-N-(2-methoxy-1-methylethyl)acetamide and (R)-two-chloro-N-(2-ethyl-six-methylphenyl)-N-(two-methoxy-1-methylethyl)acetamide in the proportion eighty-a hundred% to 20-% 
CAS RN [87392-twelve-nine] (S)- isomer [178961-twenty-1] (R)- isomer 

S-metolachlor APPLICATIONS
S-metolachlor Biochemistry Cell division inhibitor. It is described that chloroacetamides inhibit synthesis of very extended chain fatty acids (J. Schmalfuss et al., Abstr. Assembly WSSA, Toronto, 2000, 40, 117-118 P. Böger, Abstr. III Int. Weed Control Congr., Brazil, 2000). Maize tolerance of chloroacetamides is attributed to speedy detoxing by glutathione S-transferases.

S-metolachlor Mode of motion Selective herbicide, absorbed predominantly by the hypocotyls and shoots. Inhibits germination.

S-metolachlor Uses Control of yearly grasses (Echinochloa, Digitaria, Setaria, Brachiaria, Panicum and Cyperus spp.) and some wide-leaved weeds (Amaranthus, Capsella and Portulaca spp.) in maize, sorghum, cotton, sugar beet, fodder beet, sugar cane, potatoes, soya beans, peanuts, sunflowers, numerous greens, and pulse crops. Applied pre-plant incorporated, pre-emergence or early submit-emergence, at .6-one.6 kg/ha. Often utilised in mixture with broad-leaved herbicides, to extend the spectrum of activity.

S-metolachlor Phytotoxicity Tolerated by most wide-leaved crops, maize and sorghum (when safened with fluxofenim or oxabetrinil).

Frequent identify terbutryn (BSI (from 1984), E-ISO, ANSI, WSSA) terbutryne (BSI (ahead of 1984), (m) F-ISO)  IUPAC name N2-tert-butyl-N4-ethyl-6-methylthio-1,3,5-triazine-two,four-diamine
Chemical Abstracts identify N-(1,1-dimethylethyl)-N′-ethyl-6-(methylthio)-one,3,five-triazine-2,four-diamine  CAS RN [886-fifty-] 

Terbutryn Biochemistry Photosynthetic electron transportation inhibitor at the photosystem II receptor site.

Terbutryn Mode of action Selective herbicide, absorbed by the roots and foliage, with translocation acropetally by means of the xylem, and accumulation in the apical meristems.

Terbutryn Uses Used pre-emergence in winter cereals, at 1-2 kg/ha, to control Alopecurus myosuroides (black-grass) and Poa annua (once-a-year meadow grass). Between the autumn-germinating wide-leaved weeds controlled are Stellaria media (chickweed), Matricaria (mayweed), Papaver (poppies) and Veronica (speedwell), but Galium aparine (cleavers) are instead resistant. Other pre-emergence uses are on sugar cane and sunflowers, and, in combination with terbuthylazine, on beans, peas and potatoes. In mixture with metolachlor, utilised in cotton and peanuts. Also used put up-emergence (at .two-.4 kg/ha) in cereals, (at 1-3 kg/ha) in sugar cane, and as a directed spray in maize. As ‘Clarosan’, it is used to management algae and submerged vascular vegetation in waterways, reservoirs and fish ponds. Phytotoxicity Not risk-free for publish-emergence use in cereals which are below stress.
