ʻO Pinoxaden: Ke Alakaʻi i ka Herbicide Grain Field

ʻO Pinoxaden ka inoa maʻamau ma ka ʻōlelo Pelekania; 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 ka inoa kemika; ʻO ke ʻano molekala: C23H32N2O4; Nui molekala pili: 400.5; CAS login No.: [243973-20-8]; ua hōʻike ʻia ke ʻano hoʻonohonoho ma ke Kiʻi. He herbicide koho ia ma hope o ka puka ʻana mai i hoʻomohala ʻia e Syngenta. Ua hoʻokuʻu ʻia i ka makahiki 2006 a ʻoi aku kāna kūʻai aku ma mua o US$100 miliona i ka makahiki 2007.

ʻAno hana

No ka papa phenylpyrazoline hou o nā herbicides ʻo Pinoxaden a he mea hoʻopale acetyl-CoA carboxylase (ACC). ʻO kāna ʻano hana, ʻo ia ke ālai i ka synthesis waikawa momona, kahi e alakaʻi ai i ka ālai ʻana i ka ulu ʻana o nā cell a me ka mahele ʻana, a me ka make ʻana o nā mea kanu nāhelehele, me ka conductivity systemic. Hoʻohana nui ʻia ka huahana ma ke ʻano he herbicide ma hope o ka puka ʻana mai i nā mahina ʻai cereal no ka kaohi ʻana i nā nāhelehele mauʻu.

Noi

He herbicide mauʻu mauʻu koho, systemic-conductive ʻo Pinoxaden, kūpono loa, ākea ka spectrum, a komo koke i loko o nā kumu a me nā lau. Kaohi ʻana ma hope o ka puka ʻana mai o nā mauʻu gramineous makahiki i nā mahina palaoa a me ka bale, e like me ka sagebrush, Japanese sagebrush, wild oats, ryegrass, thorngrass, foxtail, hard grass, serratia a me thorngrass, a pēlā aku. Loaʻa iā ia ka hopena kaohi maikaʻi loa i nā mauʻu mauʻu paʻakikī e like me ka ryegrass. ʻO ka nui o ka mea hana he 30-60 g/hm2. He kūpono loa ʻo Pinoxaden no nā cereals puna; e hoʻomaikaʻi i ka palekana o ka huahana, hoʻohui ʻia ka fenoxafen palekana.

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

2. Palekana kiʻekiʻe no ke kaiapuni. Palekana no ka mea kanu o kēia manawa o ka palaoa, ka bale a me ka palekana biosfety ʻaʻole i hoʻolālā ʻia, palekana no nā mea kanu e hiki mai ana a me ke kaiapuni;

3. He kū hoʻokahi ke ʻano hana a he haʻahaʻa ka pilikia o ke kūʻē ʻana. He ʻano kemika hou ko Pinoxaden me nā wahi hana like ʻole, kahi e hoʻonui ai i kona wahi hoʻomohala ma ke kahua o ka hoʻokele kūʻē.
