Pinoxaden: ʻO ke alakaʻi i ka Grain Field Herbicide

唑啉草酯 ʻO Pinoxaden ka inoa maʻamau English;ʻO ka inoa kemika ʻo 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;Huina mole: C23H32N2O4;ʻO ka nui molekala pili: 400.5;Ka helu helu CAS: [243973-20-8];hōʻike ʻia ke ʻano hoʻolālā ma ke Kiʻi.He lāʻau lapaʻau ma hope o ka puka ʻana a me ka koho ʻana i hoʻomohala ʻia e Syngenta.Ua hoʻokuʻu ʻia i ka makahiki 2006 a ua ʻoi aku kāna kūʻai ʻana ma 2007 ma mua o US $100 miliona.

Mechanism o ka hana

Aia ʻo Pinoxaden i ka papa phenylpyrazoline hou o nā herbicides a he mea hoʻopale acetyl-CoA carboxylase (ACC).ʻO kāna ʻano hana ka mea nui e ālai i ka synthesis o ka momona momona, ka mea e alakaʻi ai i ka blockage o ka ulu ʻana o ka cell a me ka māhele ʻana, a me ka make ʻana o nā mea kanu weed, me ka conductivity systemic.Hoʻohana nui ʻia ka huahana ma ke ʻano he herbicide ma hope o ka puka ʻana i nā māla cereal no ka mālama ʻana i nā mauʻu mauʻu.

Palapala noi

ʻO Pinoxaden kahi herbicide weed weed koho, systemic-conductive weed herbicide, ʻoi aku ka maikaʻi, ākea ākea, a wikiwiki hoʻi i nā kumu a me nā lau.Ma hope o ka puka ʻana mai o ka mauʻu gramineous makahiki i ka palaoa a me ka bale, e like me ka sagebrush, Japanese sagebrush, oats hihiu, ryegrass, thorngrass, foxtail, hard grass, serratia and thorngrass, etc. e like me ka lau nahele.He 30-60 g/hm2 ka nui o ka mea hana.He kūpono loa ʻo Pinoxaden no nā cereals puna;e hoʻomaikaʻi i ka palekana o ka huahana, ua hoʻohui ʻia ka fenoxafen safener.

1. Hoʻomaka wikiwiki.1 a 3 mau pule ma hope o ka lāʻau lapaʻau, ʻike ʻia nā hōʻailona o ka phytotoxicity, a pau koke ka meristem i ka ulu ʻana a necroses wikiwiki;

2. Palekana kaiaola kiʻekiʻe.Palekana no ka hua palaoa i kēia manawa, ka bale a me ka biosafety ʻole, palekana no nā mea kanu hope a me ke kaiapuni;

3. He mea kū hoʻokahi ke ʻano o ka hana a haʻahaʻa ka pilikia o ke kū'ē.Loaʻa iā Pinoxaden kahi ʻano kemika hou me nā wahi hana like ʻole, e hoʻonui ana i kona wahi hoʻomohala ma ke kahua o ka hoʻokele kūʻē.
