Pinoxaden: Mutungamiriri Mumushonga Wezvipembenene Mumunda Wezviyo

Zita reChirungu rinozivikanwa nezita rekuti Pinoxaden; zita remakemikari i8-(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; Fomura yemasero: C23H32N2O4; Huremu hwemasero hunoenderana: 400.5; Nhamba yekupinda yeCAS: [243973-20-8]; fomura yechimiro inoratidzwa muMufananidzo. Imushonga wekuuraya zvipembenene mushure mekubuda uye kusarudza wakagadzirwa neSyngenta. Wakatangwa muna 2006 uye kutengeswa kwawo muna 2007 kwakapfuura US$100 miriyoni.

Maitiro ekuita

Pinoxaden iri muboka idzva remishonga yekuuraya zvipembenene inonzi phenylpyrazoline uye inodzivirira acetyl-CoA carboxylase (ACC). Maitiro ayo anonyanya kuvharira kugadzirwa kwemafuta acid, izvo zvinozoita kuti masero avharidzike uye aparadzane, uye kufa kwezvirimwa zvemasora, nekufambisa muviri. Mushonga uyu unonyanya kushandiswa semushonga wekuuraya zvipembenene mushure mekubuda kwezvirimwa muminda yezviyo kuti udzore sora.

Kushandiswa

Pinoxaden mushonga wesora unosarudza, unoshanda zvakanyanya, une mativi akasiyana-siyana, uye unokurumidza kunyudzwa kuburikidza nemadzinde nemashizha. Kudzora sora regore negore mushure mekubuda muminda yegorosi nebhari, senge sagebrush, Japanese sagebrush, wild oats, ryegrass, thorngrass, foxtail, hard grass, serratia nethorngrass, nezvimwewo. Inewo simba rakanaka rekudzora sora remagaka akadai seryegrass. Chiyero chechinhu chinoshanda i30-60 g/hm2. Pinoxaden yakakodzera kwazvo kune zviyo zvechitubu; kuti zvivandudze kuchengetedzeka kwechigadzirwa, fenoxafen inochengetedzwa inowedzerwa.

1. Kutanga nekukurumidza. Vhiki imwe kusvika nhatu mushure mekushandisa mushonga, zviratidzo zvekukuvadzwa nehutachiona hwe phytotoxicity zvinoonekwa, uye meristem inokurumidza kumira kukura uye inobuda nekukurumidza;

2. Kuchengetedzwa kwakanyanya kwezvakatipoteredza. Yakachengeteka pazvirimwa zviripo zvegorosi, bhari uye zvinhu zvisina njodzi, yakachengeteka pazvirimwa zvinotevera uye nharaunda;

3. Maitiro ekushanda akasiyana uye njodzi yekusagona kurwisa ishoma. Pinoxaden ine chimiro chitsva chemakemikari chine nzvimbo dzakasiyana dzekushanda, izvo zvinowedzera nzvimbo yayo yekukura mumunda wekutonga kusagona kurwisa.
