Cov kab mob fungal yog hom kab mob ntau tshaj plaws. Xaiv cov fungicides zoo yog kev cia siab ntawm cov neeg ua liaj ua teb. Niaj hnub no, tus editor yuav qhia txog cov tshuaj tua kab mob zoo heev - azoxystrobin. Cov tshuaj no tuaj yeem tiv thaiv thiab kho yuav luag txhua yam kab mob tshwm sim los ntawm fungi, thiab muaj ntau yam kev tiv thaiv thiab kho thiab tshem tawm. Nws yog hu ua "universal fungicide" thiab tam sim no yog siv dav tshaj plaws thiab zoo heev fungicide.
Azoxystrobin yog methoxyacrylate fungicide. Nws yog ib tug dav-spectrum, high-efficiency fungicide nrog zoo systemic conductivity, muaj zog permeability, thiab kav ntev. Nws muaj kev tiv thaiv, kho thiab tshem tawm cov teebmeem ntawm yuav luag txhua yam kab mob fungal. Nws tuaj yeem siv ntau txoj hauv kev. Nws tuaj yeem siv tsis tau tsuas yog rau qia thiab nplooj txau, tab sis kuj rau kev kho cov noob thiab kho av.
Cov yam ntxwv tseem ceeb
(1) Broad fungicide spectrum: Azoxystrobin yog ib qho dav-spectrum fungicide uas tuaj yeem siv los tiv thaiv thiab kho yuav luag txhua yam kab mob fungal. Txau ib zaug tuaj yeem tiv thaiv thiab kho ntau yam kab mob tib lub sijhawm, txo cov sijhawm txau ntau heev.
(2) Muaj zog permeability: Azoxystrobin muaj zog permeability. Nws tsis tas yuav ntxiv cov penetrant thaum siv. Nws tuaj yeem nkag mus hla cov khaubncaws sab nraud povtseg. Nws tsuas yog yuav tsum tau muab tshuaj tsuag rau sab nraum qab ntawm nplooj kom nkag mus rau sab nraum qab ntawm nplooj, ua tiav cov txiaj ntsig ntawm kev tua lub hom phiaj.
(3) Zoo zoo conductivity: Azoxystrobin muaj zog systemic conductivity. Feem ntau, tom qab daim ntawv thov, nws tuaj yeem nqus tau sai los ntawm nplooj, stems thiab cov hauv paus hniav thiab xa mus rau ntau qhov chaw ntawm cov nroj tsuag. Yog li ntawd, nws tuaj yeem siv tsis tau tsuas yog rau kev txau, tab sis kuj rau kev kho cov noob thiab kho av.
(4) Cov nyhuv ntev ntev: Azoxystrobin tuaj yeem txau rau ntawm nplooj rau 15 mus rau 20 hnub, thiab tuaj yeem siv rau cov noob hnav khaub ncaws thiab kho av rau ntau tshaj 50 hnub, uas tuaj yeem txo cov sij hawm txau ntau heev.
(5) Zoo sib xws: Azoxystrobin muaj kev sib raug zoo thiab tuaj yeem sib xyaw nrog ntau tus neeg ua haujlwm xws li thiophanate-methyl, difenoconazole, thiab dimethomorph. Kev sib xyaw tsis tsuas yog ncua sijhawm cov tshuaj tiv thaiv ntawm cov kab mob, tab sis kuj tseem txhim kho cov kev tswj xyuas.
Cov qoob loo siv tau
Txij li thaum myclobutanil muaj ntau yam kev tiv thaiv kab mob, nws tuaj yeem siv rau ntau yam khoom noj xws li nplej, pob kws, thiab nplej, cov qoob loo nyiaj ntsuab xws li txiv laum huab xeeb, paj rwb, sesame, thiab luam yeeb, zaub qoob loo xws li txiv lws suav, txiv lws suav, cucumbers, eggplants, thiab peppers, ntau yam txiv hmab txiv ntoo ntoo xws li txiv apples, pear ntoo, kiwis, mangoes, litchis, longans, thiab bananas, raws li zoo raws li ntau pua ntawm Suav tshuaj thiab paj.
Tswj cov khoom
Myclobutanil yog ib tug dav-spectrum fungicide uas yuav siv tau los tswj yuav luag tag nrho cov kab mob fungal xws li thaum ntxov blight, lig blight, grey pwm, nplooj pwm, puag rot, downy mildew, blight, powdery mildew, anthracnose, grey te, dub chaw, dub pox, cob xim av blight, dawb rot, damping-tawm, nplooj chaw, wilt, xim av, verticillium wilt, nplooj ntoos, downy mildew, tshwj xeeb tshaj yog rau powdery mildew, xeb, glume blight, web chaw, downy mildew, vine blight, lig blight, thiab nplej tawg. Nws tuaj yeem ua tiav lub hom phiaj ntawm ntau yam kev kho mob nrog ib qho tshuaj tsuag.
