Pinoxaden: Mtsogoleri mu Mankhwala Opha Herbicides

唑啉草酯 Dzina lachingerezi ndi Pinoxaden;dzina la mankhwala ndi 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;Mapangidwe a maselo: C23H32N2O4;Maselo achibale: 400,5;CAS kulowa Nambala: [243973-20-8];chilinganizo chomangika chikuwonetsedwa mu Chithunzi.Ndi mankhwala ophera udzu akamera komanso osankha opangidwa ndi Syngenta.Idakhazikitsidwa mu 2006 ndipo malonda ake mu 2007 adapitilira US $ 100 miliyoni.

Njira yochitira

Pinoxaden ndi m'gulu latsopano la phenylpyrazoline la herbicides ndipo ndi acetyl-CoA carboxylase (ACC) inhibitor.Limagwirira ake zochita ndi makamaka kutsekereza mafuta asidi kaphatikizidwe, amenenso kumabweretsa blockage wa selo kukula ndi magawano, ndi imfa ya udzu zomera, ndi zokhudza zonse madutsidwe.Mankhwalawa amagwiritsidwa ntchito kwambiri ngati mankhwala ophera udzu akamera m'minda yambewu pofuna kuwongolera udzu.

Kugwiritsa ntchito

Pinoxaden ndi mankhwala osankhidwa bwino a udzu wa udzu, wothandiza kwambiri, wotambasula, ndipo amamwedwa mwachangu kudzera mu tsinde ndi masamba.Pambuyo zikamera kulamulira pachaka gramineous namsongole m'minda ya tirigu ndi balere, monga sagebrush, Japanese sagebrush, oats zakuthengo, ryegrass, thorngrass, nkhandwe, udzu wolimba, serratia ndi thorngrass, etc. Komanso ali kwambiri kulamulira zimakhudza udzu wamakani monga ngati ryegrass.Mlingo wa yogwira pophika ndi 30-60 g/hm2.Pinoxaden ndiyoyenera kwambiri kumbewu yamasika;kupititsa patsogolo chitetezo cha mankhwala, otetezeka fenoxafen amawonjezeredwa.

1. Kuyamba mwachangu.Patangotha ​​​​masabata 1 mpaka 3 mutalandira mankhwalawa, zizindikiro za phytotoxicity zimawonekera, ndipo meristem imasiya kukula ndikukula mwachangu;

2. Kutetezedwa kwakukulu kwachilengedwe.Zotetezedwa ku mbewu zomwe zilipo panopa za tirigu, balere komanso chitetezo chamthupi chomwe sichinalephereke, chotetezeka ku mbewu zotsatira ndi chilengedwe;

3. Njira yochitirapo kanthu ndi yapadera ndipo chiopsezo chokana ndi chochepa.Pinoxaden ili ndi mawonekedwe atsopano amankhwala okhala ndi malo osiyanasiyana ochitirapo kanthu, omwe amawonjezera malo ake otukuka pantchito yolimbana ndi kukana.
