Boscalid carboximide fungicide kwa
Mafotokozedwe Akatundu
Boscalid ali ndi sipekitiramu yotakata ya bactericidal ntchito ndipo ali ndi zodzitetezera, kukhala yogwira motsutsana pafupifupi mitundu yonse ya matenda a mafangasi.Zimakhala ndi zotsatira zabwino pa kulamulira powdery mildew, imvi nkhungu, mizu zowola matenda, sclerotinia ndi mitundu yosiyanasiyana ya matenda zowola ndipo si zophweka kutulutsa mtanda kukana.Zimagwiranso ntchito polimbana ndi mabakiteriya osamva kwa ena.Amagwiritsidwa ntchito makamaka kupewa ndi kuwongolera matenda ogwiriridwa, mphesa, mitengo yazipatso, masamba ndi mbewu zakumunda.Zotsatira zawonetsa kuti Boscalid idakhudza kwambiri chithandizo cha Sclerotinia sclerotiorum ndi zonse zomwe zimayang'anira zochitika za matenda komanso index yoyang'anira matenda yoposa 80%, yomwe inali yabwino kuposa othandizira ena onse omwe akudziwika pano.
Boscalid ndi mtundu wa mitochondrion kupuma inhibitor, pokhala inhibitor ya succinate dehydrogenase (SDHI) yomwe imagwira ntchito poletsa succinate coenzyme Q reductase (yomwe imadziwikanso kuti complex II) pa mitochondrial electron transport chain, ndi njira yake yochitira zofanana ndi zomwezo. mitundu ina ya amide ndi benzamide fungicides.Zimakhala ndi zotsatira pa nthawi yonse ya kukula kwa tizilombo toyambitsa matenda, makamaka kukhala ndi mphamvu yolepheretsa spore kumera.Ilinso ndi zotsatira zabwino kwambiri za prophylactic komanso zowoneka bwino zamkati mwatsamba.
Boscalid ndi mankhwala ophera tizilombo toyambitsa matenda, omwe amatha kulowa pansi ndikufalikira pamwamba pamasamba.Ili ndi zodzitetezera kwambiri ndipo imakhala ndi machiritso ena.Itha kulepheretsanso kumera kwa spore, kukulitsa machubu a majeremusi ndi mapangidwe omangika, ndipo imakhala yothandiza pamagawo ena onse a bowa, kuwonetsa kukana kukokoloka kwa mvula komanso kulimbikira.
Boscalid ili ndi kusungunuka kwamadzi pang'ono ndipo sikusinthasintha.Itha kukhala yosasunthika m'nthaka ndi m'madzi kutengera momwe zinthu ziliri.Pali chiopsezo china chothira madzi apansi.Ndiwowopsa kwambiri kwa zinyama ndi zomera zambiri ngakhale kuti chiopsezo ndi chochepa kwa njuchi.Boscalid ali ndi kawopsedwe kakang'ono ka mammalian amkamwa.
