Tshuaj tua kab yog txoj kev ceev tshaj plaws thiab zoo tshaj plaws rau kev tiv thaiv kab mob thiab tswj. Nrog rau kev siv zog ntau ntawm cov kws tshawb fawb los ntawm ntau lub teb chaws, ntau yam tshuaj zoo rau kev tiv thaiv kab mob thiab kev tswj hwm tau raug qhia rau hauv kev ua lag luam, tswj tau zoo ntawm cov kab mob thiab ua kom muaj txiaj ntsig zoo rau kev ua tiav cov txiaj ntsig siab thiab sau qoob loo. Txawm li cas los xij, vim kev siv tshuaj tua kab tsis raug, kev puas tsuaj tshuaj tua kab tshwm sim txhua xyoo, ua rau muaj kev lag luam loj loj thiab txawm tias qoob loo tsis ua tiav. Niaj hnub no, cia kuv muab koj ib txoj hauv kev kom siv cov fungicides zoo heev.
1. Mechanism ntawm kev ua
Cov tshuaj no yogtebuconazole, ib tug dav-spectrum thiab zoo heev triazole fungicide. Nws tsuas yog inhibits lub demethylation ntawm ergosterol ntawm lub cell membrane ntawm pathogenic fungi, tiv thaiv kev loj hlob ntawm fungal hyphae thiab tsim ntawm conidia, ua tiav cov nyhuv ntawm tua cov kab mob. Cov tshuaj no muaj qhov zoo hauv kev nqus thiab tuaj yeem nqus tau sai los ntawm qhov loj hlob ntawm cov nroj tsuag thiab hloov mus rau sab saum toj.
Nws muaj kev tiv thaiv, kho, thiab tshem tawm cov txiaj ntsig ntawm ntau yam kab mob, feem ntau yog siv los tiv thaiv thiab tswj ntau yam kab mob fungal ntawm cov qoob loo xws li nplej, nplej, txiv laum huab xeeb, zaub, txiv tsawb, txiv apples, pears, thiab pob kws thiab sorghum. Txawm li cas los xij, tebuconazole tuaj yeem muaj qee yam cuam tshuam rau kev loj hlob thiab kev faib tawm ntawm cov nroj tsuag, yog li inhibiting kev loj hlob ntawm cov nroj tsuag. Yog tias qhov ntau npaum li cas thiab txau ntau zaus rau lub sijhawm ntev, nws yuav ua rau cov tshuaj tua kab puas tsuaj thiab muaj zog inhibitory nyhuv ntawm cov nroj tsuag kev loj hlob thiab kev loj hlob, zoo heev txo qhov kev loj hlob ntawm cov nroj tsuag.

Thaum siv cov koob tshuaj pom zoo, nws tuaj yeem tswj hwm kev noj zaub mov zoo ntawm cov nroj tsuag, txhawb kev loj hlob ntawm kev loj hlob, txhawb kev thauj mus los rau hauv cov txiv hmab txiv ntoo, nce cov ntsiab lus ntawm cov suab thaj, proteins, thiab lwm yam khoom hauv cov txiv hmab txiv ntoo, ua kom cov nplej puv, nce txhiab nplej hnyav, thiab txhim kho txiv hmab txiv ntoo zoo.
(5) Kev tiv thaiv thiab kho cov teebmeem nrog kev tshem tawm: Tebuconazole muaj cov txiaj ntsig zoo ntawm kev tiv thaiv kab mob thiab kev kho mob los ntawm inhibiting kev loj hlob ntawm fungal hyphae thiab tsim ntawm conidia los ntawm inhibiting ergosterol ntawm cov kab mob intracellular membrane.
(6) Kev sib xyaw muaj peev xwm zoo: Tebuconazole tuaj yeem sib xyaw nrog ntau yam tshuaj tua kab xws li prochloraz, feniconazole, zinc propionate, fipronil, thiab azoxystrobin, nrog rau cov txiaj ntsig zoo heev. Nws tsis tsuas yog nthuav tawm cov kab mob bactericidal, tiv thaiv kab mob, tab sis kuj tseem muaj txiaj ntsig zoo rau kev tua kab mob.
3. Cov nyhuv inhibitory ntawm tebuconazole rau cov qoob loo
Tebuconazole yog ib qho tshuaj tua kab mob triazole uas muaj kev cuam tshuam rau cov nroj tsuag ntawm tes faib thiab elongation, tab sis nws txoj kev nyab xeeb tsis zoo. Tshwj xeeb tshaj yog thaum lub sij hawm yub theem, cov nyhuv inhibitory yog ntau pronounced. Tebuconazole ncua kev tshem tawm cov noob txheej txheej tuaj yeem ua rau cov noob tsis tuaj yeem tawg yog tias ntau npaum li qhov pom zoo. Nyob rau hauv lub caij nplooj ntoos hlav, kev siv ntau dhau tuaj yeem ua kom tiav qhov kev loj hlob ntawm yub, nrog rau cov kev mob tshwm sim tshwj xeeb.
4. Kev siv
(1) Kev sib xyaw cov noob: txhawm rau tiv thaiv thiab tswj cov kab mob hauv av xws li cov kab mob hauv av, qia rot, thiab tag nrho cov qoob loo xws li nplej, pob kws, thiab nplej, 10% ncua kev tshem tawm cov noob txheej ntawm fenpropanol tuaj yeem siv los sib xyaw cov noob hauv ib qho piv txwv ntawm 200-300 milliliters/100 kilograms, uas tuaj yeem tiv thaiv thiab tswj tau qhov tshwm sim thiab kev puas tsuaj ntawm ntau yam kab mob hauv av. 32% pentazole · imidacloprid suspension noob txheej kuj tuaj yeem siv los sib xyaw cov noob hauv qhov sib piv ntawm 300-500 milliliters / 100 kilograms. Nws tuaj yeem tiv thaiv thiab tswj tau ntau yam kab mob, nrog rau cov kab tsuag xws li aphids thiab planthoppers, nrog lub txee lub neej txog li 80-100 hnub.
(2) Kev kho av: Ua ntej lossis thaum lub sijhawm sowing, siv 3-4 kilograms ntawm 2% benzothiazole qeeb-tso granules ib evkawj, sib tov sib npaug nrog cov organic chiv lossis cov av zoo, thiab tom qab ntawd siv rau hauv qhov kom tiv thaiv tau zoo thiab tswj kev puas tsuaj ntawm cov kab mob hauv av thiab kab tsuag.
(3) hauv paus irrigation: Thaum cog qoob loo xws li txiv lws suav, kua txob, thiab eggplants, ib tug 32% imidacloprid ncua kev kawm ntawv noob txheej neeg sawv cev diluted los ntawm 1000-1500 zaug yuav siv tau rau hauv paus irrigation, ua raws li los ntawm cov av npog, uas yuav ua tau zoo. tiv thaiv qhov tshwm sim ntawm cov kab mob hauv av thiab kab tsuag xws li hauv paus rot, kab mob wilt, thiab dawb grubs.
(4) Txau: txhawm rau tswj cov nplej, pob kws, nplej thiab lwm cov qoob loo powdery mildew, xeb, lub taub hau smut, scab, pob kws nplooj thiab lwm yam kab mob, siv 3000 ~ 4000 zaug ntawm 43% tebuconazole ncua lossis 2500 ~ 3000 zaug ntawm 40% oxime kab mob tebuconazole ncua kev kawm ntawv.
5. Ceev faj
Txhawm rau txhim kho kev tiv thaiv thiab kho cov teebmeem ntawm tebuconazole thiab txo cov kev pheej hmoo ntawm kev puas tsuaj rau cov tshuaj, cov ntsiab lus hauv qab no yuav tsum tau sau tseg thaum siv nws:
(1) Sim tsis txhob siv nws thaum lub sij hawm yub theem thiab thaum ntxov ntawm cov nroj tsuag fruiting.
(2) Sim sib tov nrog lwm cov tshuaj kom ntau li ntau tau. Kev sib xyaw tebuconazole nrog rau lwm cov tshuaj tuaj yeem txo qis cov nyhuv inhibitory ntawm tebuconazole ntawm kev loj hlob.
(3) Raws li kev pom zoo ntau npaum, tebuconazole muaj kev ua haujlwm siab thiab tuaj yeem ua tiav kev tiv thaiv thiab kev kho mob zoo ntawm qhov tsis tshua muaj siab. Tsis txhob nce qhov concentration arbitrarily thaum siv.
