Pinoxaden: Tus Thawj Coj hauv Grain Field Herbicide

唑啉草酯 lus Askiv lub npe yog Pinoxaden; Lub npe tshuaj yog 8-(2,6-diethyl-4-methylphenyl)-1,2,4,5-tetrahydro-7-oxo-7H- Pyrazolo[1,2-d][1,4,5]oxadiazepine- 9-yl 2,2-dimethylpropionate; Cov mis mos molecular: C23H32N2O4; kwv tij molecular mass: 400.5; CAS ID: [243973-20-8]; tus qauv qauv qhia nyob rau hauv daim duab . Nws yog ib qho tshuaj tua kab mob tom qab tshwm sim thiab xaiv tshuaj tua kab tsim los ntawm Syngenta. Nws tau tsim tawm hauv 2006 thiab nws qhov muag hauv 2007 tau tshaj US $ 100 lab.

Mechanism ntawm kev ua

Pinoxaden belongs rau chav kawm phenylpyrazoline tshiab ntawm cov tshuaj tua kab mob thiab yog acetyl-CoA carboxylase (ACC) inhibitor. Nws cov txheej txheem ntawm kev txiav txim yog tsuas yog los thaiv fatty acid synthesis, uas nyob rau hauv lem ua rau blockage ntawm cell loj hlob thiab faib, thiab tuag ntawm nroj tsuag nroj tsuag, nrog rau cov kab mob. Cov khoom no tsuas yog siv los ua tshuaj tua kab mob tom qab tshwm sim hauv cov teb nplej rau kev tswj cov nyom nyom.

Daim ntawv thov

Pinoxaden yog ib qho kev xaiv, cov kab ke-conductive nyom nyom herbicide, ua tau zoo, dav-spectrum, thiab sai absorbed los ntawm stems thiab nplooj. Tom qab tshwm sim ntawm cov nroj tsuag gramineous txhua xyoo nyob rau hauv cov nplej thiab barley teb, xws li sagebrush, Japanese sagebrush, qus oats, ryegrass, thorngrass, foxtail, nyuaj nyom, serratia thiab pos, thiab lwm yam. raws li ryegrass. Qhov ntau npaum ntawm cov khoom xyaw nquag yog 30-60 g / h 2. Pinoxaden yog heev haum rau lub caij nplooj ntoos hlav cereals; txhawm rau txhim kho cov khoom lag luam kev nyab xeeb, kev nyab xeeb fenoxafen ntxiv.

1. Ceev ceev pib. 1 mus rau 3 lub lis piam tom qab siv tshuaj, cov tsos mob ntawm phytotoxicity tshwm sim, thiab meristem sai sai nres thiab necroses sai;

2. Kev ruaj ntseg ecological siab. Muaj kev nyab xeeb rau cov qoob loo tam sim no ntawm cov nplej, barley thiab tsis yog lub hom phiaj biosafety, nyab xeeb rau cov qoob loo tom ntej thiab ib puag ncig;

3. Cov txheej txheem ntawm kev ua haujlwm yog qhov tshwj xeeb thiab qhov kev pheej hmoo ntawm kev tiv thaiv tsawg. Pinoxaden muaj cov qauv tshuaj tshiab nrog cov chaw ua haujlwm sib txawv, uas ua rau nws qhov chaw loj hlob hauv kev tswj hwm kev tiv thaiv.
