After a 6-month provisional approval period, the International Organization for Standardization (ISO) recently officially approved the common names of three new pesticide active ingredients, all of which are herbicide ingredients, including Indolauxipyr, Icafolin and Pyraquinate.

IUPAC: (2RS,4RS)-4-({[(5S)-3-(3,5-difluorophenyl)-5-vinyl-4,5-dihydroisoxazol-5-yl] Carbonyl}amino)tetrahydrofuran-2-carboxylic acid, containing 40-70% of the (2R,4R)-isomer and 60-30% of the (2S,4S)-isomer
CAS name: 2,5-Dihydro-3,4-dideoxy-4-[[[(5S)-3-(3,5-difluorophenyl)-5-vinyl-4,5-dihydro -5-isoxazolyl]carbonyl]amino]-threonine
CAS NO.: 2254752-27-5
Molecular formula: C17H16F2N2O5
Categories: Herbicides (Uncategorized)
Pyraquinate
Status: ISO 1750 (ratified)
IUPAC PIN: 4-[3-(3-Chlorophenyl)-1,5-dimethyl-2,4-dioxo-1,2,3,4-tetrahydro(quinazoline-6-carbonyl )]-1,3-Dimethyl-1H-pyrazol-5-yldiethylcarbamate
IUPAC: 4-{[3-(3-chlorophenyl)-1,5-dimethyl-2,4-dioxo-1,2,3,4-tetrahydroquinazolin-6-yl ]carbonyl}-1,3-dimethyl-1H-pyrazol-5-yldiethylcarbamate
CAS name: 4-[[3-(3-chlorophenyl)-1,2,3,4-tetrahydro-1,5-dimethyl-2,4-dioxo-6-quinazolinyl ]carbonyl]-1,3-dimethyl-1H-pyrazol-5-yl N,N-diethylcarbamate
CAS NO.: 2378093-62-8
Molecular formula: C27H28ClN5O5
Categories: Herbicides (Benzoylpyrazoles)
Pyraquinate has a super strong systemic conduction effect, and it also has excellent control effect on older weeds. It can control resistant weeds such as stephenia chinensis, barnyardgrass, weed grass, weeds, rice Lishihe, and barnyardgrass. Pyraquinate has a different mechanism of action from cyhalofop-ethyl and fenfenpyramid, and the performance of cyhalofop-methyl and fenfenpyr has excellent performance under severe resistance conditions, so Pyraquinate has a broad market prospect .
Pyraquinate is a new type of herbicide independently created in China with high efficiency, low toxicity and low residue. It has outstanding control effect against drug-resistant D. chinensis, and has high safety in rice. It has broken through the major problem of insufficient safety of traditional HPPD herbicides on indica rice. It is an ideal rice field herbicide to replace traditional medicaments, and has high application value and originality.
