Bentazone ndi mankhwala a herbicide omwe amagulitsidwa ndi BASF mu 1972, ndipo zomwe zikuchitika padziko lonse lapansi ndi pafupifupi matani 9000.Ndi kuletsedwa kwa madontho 2,4 ku Vietnam, kuphatikiza kwa methamphetamine ndi oxazolamide kukuyembekezeka kukhala ndi chiyembekezo chogwiritsa ntchito mbewu zampunga zakomweko.Kodi mitundu yakale imeneyi, yomwe yatha pafupifupi zaka 50, idzatsitsimutsanso msika waku Southeast Asia?
Chiyambi cha Zamalonda
Dzina la Chemical:3-isopropyl-1H-2,1,3-benzothiazide-4 (3H) - ketone 2,2-dioxide, yomwe imadziwika kuti bentazone;Mayina ena: Bendazone, Paicao Dan.Mapangidwe ake ndi awa.
Njira yochitira:Fencao pine ndi mankhwala ophera komanso osankha posankha mbande, omwe amagwiritsidwa ntchito m'minda youma ndipo amapatsira ma chloroplasts kudzera mu kulowa kwa masamba kuti aletse photosynthesis.Nyemba za soya zimatha kusokoneza methamphetamine, ndikupangitsa kuti ikhale yogwira ntchito.Komabe, zomera tcheru zimaletsedwa m'kati mwa carbon dioxide assimilation pambuyo pa ntchito, mpaka zonse zitayima, ndipo masamba awo amanyansidwa ndi kutembenukira chikasu, zomwe zimatsogolera ku imfa.Nyengo yadzuwa komanso yofunda imathandizira kuti mankhwala azigwira ntchito.Akagwiritsidwa ntchito m'minda ya paddy, amatha kulowa m'masamba ndikuyamwa m'mizu, yomwe imafalikira ku tsinde ndi masamba, ndikuletsa kwambiri photosynthesis ya udzu ndi metabolism yamadzi, zomwe zimayambitsa njala ya zakudya komanso kuwonongeka kwa thupi komwe kumabweretsa imfa.
Zinthu zowongolera:Itha kulamulira udzu wotakata ndi namsongole wa Cyperaceae, ndipo ingagwiritsidwe ntchito kupalira m'minda ya soya, chimanga, nandolo, ndi mpunga, monga theophrasti theophrasti, chikwama cha abusa, mgoza wamadzi, Datura wopanda spind, Helianthus, polygonum, Portulaca. , Ragweed, Xanthium, heterotypic sedge, bakha lilime udzu (zotsatira zake ndi zabwino mu nthawi yoyamba mpaka yachiwiri tsamba, ndipo zotsatira zake zimachepetsedwa kwambiri mu nthawi ya masamba achitatu), udzu wa khungu la vwende, sparganium, ndi zina zotero. pakuwongolera nyengo yozizira Anthemis, Matricaria, chrysanthemum ya ngale, ndi bane ya nkhumba m'munda wa mbewu zambewu zamasika.
