Pyraclostrobin ndi methoxyacrylate fungicide yokhala ndi pyrazole yopangidwa ndi BASF ku Germany mu 1993. Yagwiritsidwa ntchito pa mbewu zoposa 100.Ili ndi ma bactericidal spectrum ambiri, ambiri amalimbana ndi tizilombo toyambitsa matenda, komanso chitetezo chokwanira.Imakhala ndi kugonana kolimba, imathandizira kukana kupsinjika kwa mbewu, imathandizira kukula kwa mbewu, imakana ukalamba ndi ntchito zina.

1. Njira yochitira zinthu.
Pyraclostrobin ndi choletsa kupuma kwa mitochondrial.Imalepheretsa kupuma kwa mitochondrial poletsa kusamutsa kwa ma elekitironi pakati pa cytochrome b ndi C1, kupangitsa mitochondria kulephera kupanga ndikupereka mphamvu (ATP) yofunikira kuti kagayidwe kake ka cell, ndikupangitsa kufa kwa cell.kufa.
Pyraclostrobin imakhala ndi mphamvu yoletsa kumera kwa spores, imakhala ndi antibacterial ntchito yolimbana ndi bowa wamtundu uliwonse wa zomera (Ascomycetes, Basidiomycetes, Oomycetes ndi Deuteromycetes), ndipo imakhala ndi chitetezo ndipo Imakhala ndi zotsatira zochiritsira ndipo imakhala ndi malowedwe abwino komanso machitidwe.Itha kugwiritsidwa ntchito popopera mbewu pazitsa ndi masamba, kuthira mankhwala ophera tizilombo pamadzi, ndikuthira njere.Komanso kwambiri kusankha.Ndi yabwino kwa mbewu, anthu, ziweto ndi zamoyo zopindulitsa, ndipo kwenikweni ilibe kuipitsa chilengedwe.Pomaliza, ma conductive ntchito zake m'zomera ndi zamphamvu, zomwe zimatha kusintha magwiridwe antchito amtundu wa mbewu ndikukulitsa kukana kupsinjika kwa mbewu.

2. Kuteteza ndi kulamulira zinthu ndi makhalidwe
(1) Kutseketsa kosiyanasiyana: Broad-spectrum sterilization pyraclostrobin itha kugwiritsidwa ntchito pa mbewu zosiyanasiyana monga tirigu, mtedza, mpunga, masamba, mitengo yazipatso, fodya, mitengo ya tiyi, zomera zokongola, kapinga, ndi zina zotero. dzimbiri, powdery mildew, downy mildew, choipitsa, anthracnose, nkhanambo, mawanga a bulauni, damping off ndi matenda ena oyambitsidwa ndi Ascomycetes, Basidiomycetes, Deuteromycetes ndi Oomycetes bowa.Ndiwothandiza polimbana ndi nkhaka powdery mildew, downy mildew, nthochi nkhanambo, banga la masamba, mphesa downy mildew, anthracnose, powdery mildew, choipitsa choyambilira, choipitsa chakumapeto, powdery mildew ndi masamba a tomato ndi mbatata.Kupewa ndi kuwongolera zotsatira.
（2）Kuphatikizika kwa kupewa ndi kuchiza: Ili ndi zoteteza komanso zochiritsira, ndipo imakhala ndi kulowa bwino komanso zotsatira zadongosolo.Itha kugwiritsidwa ntchito ndi kupopera kwa tsinde ndi masamba, kugwiritsa ntchito madzi pamwamba, kukonza mbewu, ndi zina.
(3) Chisamaliro cha thanzi la zomera: Kuwonjezera pa zotsatira zake zachindunji pa mabakiteriya a pathogenic, pyraclostrobin, yomwe imagonjetsedwa ndi kupsinjika maganizo ndikuwonjezera kupanga, ingayambitsenso kusintha kwa thupi mu mbewu zambiri, makamaka chimanga.Mwachitsanzo, imatha kupititsa patsogolo ntchito ya nitrate (nitrification) reductase, potero kukulitsa kukula kwa mbewu.Kuchuluka kwa nayitrogeni panthawi ya kukula kofulumira.Pa nthawi yomweyo, akhoza kuchepetsa ethylene biosynthesis, potero kuchedwetsa mbewu senescence.Pamene mbewu anaukira ndi mavairasi, akhoza imathandizira mapangidwe kukana mapuloteni, amene ali ndi zotsatira zofanana ndi kaphatikizidwe wa kukana mapuloteni ndi mbewu ya salicylic acid kaphatikizidwe. .Ngakhale zomera sizidwala, pyraclostrobin imatha kuonjezera zokolola polimbana ndi matenda achiwiri komanso kuchepetsa kupsinjika maganizo kuchokera kuzinthu zowonongeka.
