Downy mildew, blight, thiab lig blight raug suav hais tias yog cov kab mob uas kis tau sai tshaj plaws, ua rau muaj kev phom sij loj tshaj plaws, thiab yog qhov nyuaj tshaj plaws los tswj, tshwj xeeb tshaj yog nyob rau hauv cucumbers, melons, txiv hmab txiv ntoo, qos yaj ywm, peppers thiab lwm yam qoob loo, ua rau loj heev. poob txhua xyoo. Niaj hnub no, kuv xav qhia rau koj ib tus neeg sawv cev zoo tshaj plaws rau kev tiv thaiv thiab kho cov kab mob no --fluorobacteria thiab propamocarb, uas tuaj yeem tiv thaiv, kho thiab tshem tawm cov kab mob mildew, blight thiab lig blight.
1. Taw qhia txog tshuaj
Fluoride ·propamocarb yog cov tshuaj tua kab mob los ntawm 62.5 g / L fluopyram + 625 g / L propamocarb hydrochloride. Fluopyram yog ib qho amide fungicide nrog muaj zog permeability thiab zoo inhibitory nyhuv ntawm txhua hom loj ntawm Oomycete pathogens.
Propamocarb hydrochloride yog ntau qhov chaw ua haujlwm fungicide nrog cov khoom siv hauv lub cev thiab kev ua haujlwm siab ob sab hauv thiab sab nraud. Nws tuaj yeem tiv thaiv kev tsim cov spores thiab zoospores, inhibit qhov kev loj hlob thiab kev loj hlob ntawm cov kab mob hyphae, thiab muaj kev tiv thaiv thiab kho cov kab mob.
Thaum ob qho tib si sib xyaw, lawv muaj kev tiv thaiv thiab kho mob. Nws muaj kev ruaj khov thiab tswj tau zoo ntawm cov kab mob tshwm sim los ntawm Oomycetes, tshwj xeeb tshaj yog rau cov kab mob tshwm sim los ntawm cov kab mob downy mildew thiab phytophthora.
2. Cov yam ntxwv tseem ceeb
(1) Broad sterilization spectrum:
Tus neeg sawv cev no tuaj yeem kho cov kab mob mildew, lig blight, blight, damping-off, dub shank thiab lwm yam kab mob tshwm sim los ntawm fungi xws li Hypospora, Discophyllum, Downy Mildew, Phytophthora, Pseudoperonospora thiab Pythium.
Txhua tus muaj kev tiv thaiv zoo heev thiab kho tau zoo.
(2) Muaj zog permeability: Tus neeg sawv cev no muaj qhov muaj zog permeability thiab tuaj yeem nkag los ntawm sab xub ntiag ntawm nplooj mus rau sab nraum qab ntawm nplooj kom tua cov kab mob nyob rau sab nraum qab ntawm nplooj.
(3) Kev kho kom zoo: Tus neeg sawv cev no muaj kev cuam tshuam zoo heev ntawm kev tso tawm thiab txav ntawm zoospores, hyphae germination thiab kev loj hlob, thiab sporulation ntawm txhua theem. Nws muaj kev tiv thaiv thiab kho cov teebmeem, thiab kev kho mob zoo dua.
(4) Tsis muaj qhov sib txawv: Tus neeg sawv cev no feem ntau nthuav tawm cov kab mob bactericidal los ntawm kev ua ntawm cov proteins tshwj xeeb ntawm cov cell membrane thiab cytoskeleton. Cov kab mob bactericidal no txawv kiag li ntawm txhua qhov tam sim no paub Oomycete fungicides. Tsis muaj kev sib tw.
(5) Lub sij hawm ntev ntawm cov nyhuv: Tus neeg sawv cev no tuaj yeem nyob hauv lub cev ntawm cov qoob loo rau lub sijhawm ntev kom ua tiav lub hom phiaj ntawm kev ua kom tsis muaj menyuam. Lub sijhawm ntawm cov nyhuv yog ntev dua, thiab feem ntau lub sijhawm ntawm cov nyhuv tuaj yeem ncav cuag ntau dua 15 hnub.
(6) Kev siv yooj yim: Vim tias tus neeg sawv cev muaj zog permeability thiab kev ua haujlwm zoo, nws tuaj yeem siv rau kev txau thiab cov hauv paus irrigation.
3. Siv cov qoob loo
Tus neeg sawv cev tuaj yeem siv dav hauv cucumbers, txiv lws suav, eggplants, peppers, watermelons, zucchini, grapes, apples, pears, strawberries, qos yaj ywm, lettuce, luam yeeb thiab lwm yam qoob loo.
4. Tiv thaiv thiab tswj cov khoom
Feem ntau siv los tiv thaiv thiab tswj damping-off, downy mildew, blight, dub shank, lig blight thiab lwm yam kab mob.
5. Siv thev naus laus zis
Thaum loj hlob txiv lws suav, cucumbers, peppers, eggplants, watermelons thiab lwm yam qoob loo, koj muaj peev xwm siv 1000 zaug ntawm 687.5/liter Fluorobacterium Propamidiocarb ncua kev kawm ntawv rau irrigate cov hauv paus hniav. Nws tuaj yeem tiv thaiv thiab tswj tau qhov tshwm sim ntawm downy mildew, kab mob sib kis thiab lwm yam kab mob thoob plaws hauv cov yub theem, thiab muaj cov nyhuv ntev.
Nyob rau theem pib ntawm cov kab mob xws li cov kab mob me me thiab lig blight ntawm cucumbers, melons, txiv hmab txiv ntoo, txiv lws suav, thiab qos yaj ywm, 687.5 / liter fluorobacteria · propamocarb ncua kev kawm tuaj yeem txau 900 txog 1000 zaug. Txau ib zaug txhua 7 hnub rau 2 mus rau 3 zaug tuaj yeem tswj kev nthuav dav thiab kev sib kis ntawm tus kab mob sai sai, thiab thaum kawg tshem tawm cov kab mob tag nrho.
