Pyraclostrobin inonzi methoxyacrylate fungicide ine pyrazole structure yakagadzirwa neBASF kuGermany muna 1993. Yakashandiswa pane zvinopfuura 100 zvirimwa.Iyo ine yakakura bactericidal spectrum, akawanda anonangwa utachiona, uye kusadzivirirwa.Iine bonde rakasimba, inovandudza kusagadzikana kwezvirimwa, inosimudzira kukura kwembesa, inopesana nekukwegura uye mamwe mabasa.

1. Nzira yekuita.
Pyraclostrobin inonzi mitochondrial respiration inhibitor.Inodzivirira kufema kwemitochondrial nekudzivirira kufambisa kweelectron pakati pe cytochrome b neC1, zvichiita kuti mitochondria isakwanise kuburitsa uye kupa simba (ATP) rinodiwa kune yakajairika cell metabolism, pakupedzisira ichikonzera kufa kwesero.kufa.
Pyraclostrobin ine simba rakasimba rekudzivisa kumera kwepathogenic spores, ine zvakakosha antibacterial basa pamusoro pezvinenge zvose zvinomera pathogenic fungi (Ascomycetes, Basidiomycetes, Oomycetes uye Deuteromycetes), uye ine dziviriro uye Iine maitiro ekurapa uye ine yakanaka yekupinda uye systemic migumisiro.Inogona kushandiswa nekupfapfaidza pamadzinde nemashizha, kuisa mishonga yezvipembenene pamvura, nekurapa mbeu.Uyewo kunyanya kusarudza.Yakachengeteka kune zvirimwa, vanhu, zvipfuyo uye zvipenyu zvinobatsira, uye haina kusvibisa nharaunda.Chekupedzisira, kuita kwayo kwekuita muzvirimwa kwakasimba, izvo zvinogona kuvandudza zvirimwa physiological mabasa uye kuwedzera zvirimwa kusagadzikana kuramba.

2. Kudzivirira uye kutonga zvinhu uye maitiro
(1) Broad-spectrum sterilization: Broad-spectrum sterilization pyraclostrobin inogona kushandiswa pazvirimwa zvakasiyana siyana segorosi, nzungu, mupunga, miriwo, miti yemichero, fodya, miti yetii, zvirimwa zvekushongedza, patsangadzi, nezvimwewo. Dzivirira uye kudzora kusvibiswa kwemashizha, ngura, powdery mildew, downy mildew, blight, anthracnose, scab, brown spot, damping off nezvimwe zvirwere zvinokonzerwa neAscomycetes, Basidiomycetes, Deuteromycetes neOomycetes fungi.Inoshanda mukurwisa cucumber powdery mildew, downy mildew, banana scab, leaf spot, grape downy mildew, anthracnose, powdery mildew, early blight, late blight, powdery mildew neleaf blight yemadomasi nembatatisi.Kudzivirira uye kutonga maitiro.
(2) Kusanganiswa kwekudzivirira uye kurapwa: Iine kudzivirira uye kurapa mhedzisiro, uye ine yakanaka yekupinda uye systemic mhedzisiro.Inogona kushandiswa ne stem uye shizha pfapfaidzo, mvura pamusoro pekushandisa, kurapwa kwembeu, nezvimwe.
(3) Kuchengetedzwa kwehutano hwekudyara: Pamusoro pekuita kwayo kwakananga pamabhakitiriya epathogenic, pyraclostrobin, iyo inopesana nekushushikana uye inowedzera kugadzirwa, inogonawo kukonzera shanduko yemuviri muzvirimwa zvakawanda, kunyanya zviyo.Semuenzaniso, inogona kuwedzera basa re nitrate (nitrification) reductase, nekudaro ichivandudza kukura kwembeu.Kutora nitrogen munguva dzekukura nokukurumidza.Panguva imwecheteyo, inogona kuderedza ethylene biosynthesis, nekudaro ichinonotsa senescence yezvirimwa.Kana zvirimwa zvikarwiswa nemavhairasi, zvinogona kukurumidzira kuumbwa kwemapuroteni ekupikisa, ayo ane mhedzisiro yakafanana neyekuumbwa kwemapuroteni ekupikisa nechirimwa chega salicylic acid synthesis. .Kunyangwe zvidyarwa zvikasarwara, pyraclostrobin inogona kuwedzera goho nekudzora zvirwere zvechipiri uye kuderedza kushushikana kubva kune abiotic factor.
