Clethodim udzu kusankha herbicide kwa udzu

Mafotokozedwe Akatundu

Clethodim ndi mankhwala osankha udzu a cyclohexenone omwe amalimbana ndi udzu ndipo sangaphe zomera zamasamba.Mofanana ndi mankhwala a herbicide aliwonse, komabe, ndi othandiza kwambiri pa mitundu ina ikaikidwa pa nthawi yoyenera.Ndiwothandiza makamaka pa udzu wapachaka monga bluegrass, ryegrass, foxtail, crabgrass, ndi Japanese stiltgrass.Mukawapopera pa udzu wolimba osatha monga fescue kapena orchardgrass onetsetsani kuti mukugwiritsa ntchito herbicide pamene udzu uli waung'ono (pansi pa 6"), mwinamwake pangakhale kofunikira kupopera kachiwiri mkati mwa masabata 2-3 kuchokera ku ntchito yoyamba kuti muphe. zomera.Clethodim ndi mafuta acid synthesis inhibitor, amagwira ntchito poletsa acetyl CoA carboxylase (ACCase).Ndi systemic herbicide, clethodim imatengedwa mwachangu ndikusamutsidwa mosavuta kuchokera kumasamba odulidwa kupita ku mizu ndi mbali zomwe zimamera.
Clethodim imagwira bwino ntchito ikagwiritsidwa ntchito yokha kapena mu tanki kusakaniza ndi mankhwala ophatikizika a Gulu A monga ma fops (Haloxyfop, Quizalofop).

Clethodim angagwiritsidwe ntchito kulamulira udzu pachaka ndi osatha mu mbewu zambiri, kuphatikizapo nyemba, udzu winawake, clover, conifers, thonje, cranberries, gar.lic, anyezi, zokongoletsera, chiponde, soya, sitiroberi, sugarbeet, mpendadzuwa, ndi masamba.

Clethodim ilinso ndi ntchito zabwino zoyendetsera malo pamene mukuyesera kulamulira udzu womwe si wamba.Ndimakonda kwambiri clethodim poyang'anira ma stiltgrass a ku Japan m'madera omwe muli osakaniza bwino a forbs omwe sindikufuna kuvulaza, monga clethodim amandilola kupha udzu ndikumasula ma forbs kuti atenge malo a stiltgrass omwe amafa.

Clethodim ndiyokhazikika pang'ono m'nthaka yambiri yomwe imanenedwa kuti theka la moyo wamasiku atatu (58).Kuwonongeka kumachitika makamaka ndi njira za aerobic, ngakhale photolysis ingathandize.Imawonongeka mwachangu pamawonekedwe amasamba ndi acid-catalyzed reaction and photolysis.Clethodim yotsalayo imalowa mwachangu mu cuticle ndikulowa muzomera.
