Hlaukasxyl: Cov Kev Qhia Txog Kev Siv Kev Siv, Cov Nyiaj Pab, thiab Kev Siv

Hlauasyl: siv, cov txiaj ntsig, thiab kev siv qoob loo

Hlauasyl yog lub pobzeb ntawm cov nroj tsuag kab mob nroj tsuag niaj hnub. Qhov kev ua yeeb yam tshwj xeeb no tiv thaiv cov qoob loo thoob ntiaj teb cog qoob loo los ntawm inhibiting Ribosomal RNArthesis hauv omycete pathogens, cuam tshuam lawv cov protein ntau lawm. Nws cov cim tshwj xeeb biochemical muab ob qho tib siCov Khoom Tiv Thaiv thiab Ntsej Muag, ua rau nws tseem ceeb rau kev sib txuas qee qhov kev ua liaj ua teb muaj kab mob txaus siab tshaj plaws.

Raws li cov txheej txheem fungicide, hlauaschaxy tau pom zookev mus ncig nyob hauv cov ntaub so ntswgCov. Txawm hais tias thov kev kho cov noob, av ua av, lossis cov tshuaj tsuag cov roj av, cov nroj tsuag tau nqus nws ntawm cov hauv paus hniav, qia, lossis nplooj. Nws ces tsiv bidirectionally -} upward mus rau kev loj hlob tshiab thiab qis rau hauv paus systems. Qhov kev faib tawm thoob plaws tiv thaiv tag nrho cov nroj tsuag tawm tsam pathogens hauv lubPeronosporesKev txiav txim, tshwj xeeb:

• Phytophthora hom(Ua rau lub ntsej muag xiav nyob rau hauv qos yaj ywm / txiv lws suav thiab cov rots rots)
• PLASMOPA VITICOLA(grape downy mildew)
• Peronospora Hom(Lub luag haujlwm rau downy mildews nyob rau saum ntoo khaub lig, dos, thiab luam yeeb)
• Pythium SPP.(damping - tawm hauv seedlings)

Tsis zoo li bod -} spectrum fungicides, hlauasyl's xaiv tau cov kab mob muaj txiaj ntsig thaum lub hom phiaj ua rau muaj kev phom sij.

Hlauasyl tuaj yeem thov rau ntau txoj hauv kev nyob ntawm cov qoob loo thiab kab mob siab:

1. Kev kho cov noob: Siv ua txheej (2 {- 3% los ntawm cov noob nyhav) los tiv thaiv kev txhim kho cov hauv paus hniav thiab tua los ntawm av {}} bamogens. Rau pobkws, 20% metkaxyl-mation ntawm 53-76g / 100kg noob tswjLub suab ua pythiuminduced stalk rot. Soybean and cotton seed treatments reduce seedling mortality by >95%, muaj kev tiv thaiv ntev li 30-40 hnub tom qab cog.
2. Av drenching / hauv - furrow daim ntawv thov: Cov qauv no tsim thaj chaw tiv thaiv ib ncig ntawm cov hauv paus hniav. Lws suav thiab kua txob transplants tau txais txiaj ntsig los ntawm cov av drenches (500x dilution) lossis cov noob cag uas txo qisPhytophthoraCag thiab yas rots.
3. Foliar sprays: Thov ib leeg lossis hauv mixtures (nrog MANCOZE (nrog tooj liab), cov tshuaj tsuag no tswj cov kab mob aerial. Rau cov qos ntawd lig blight, 25% wp thov ntawm 500x dilution txhua 14 hnub ua rau muaj kev cuam tshuam tus kab mob no. Rau cov txiv hmab downy mildew, 58% wettable hmoov (400-600x dilution) muab 10-15 hnub ntawm kev tiv thaiv.

Kab mob tiv thaiv mus rau hlauAXyl tau tsim sai tom qab nws cov lus qhia, xav tau cov tswv yim zoo:

• Ib txwm ua keNrog cov fungicides tiv thaiv (piv txwv li, mangozyb hauv 58% hlauaxy .. {manganese zinc wp) kom ncua kev tiv taus.
• HLOOV COV NTAUB NTAWVNrog tsis paub tseeb hom kev nqis tes ua (piv txwv li, carboxylic acid nyob hauv lossis quinone sab nraud inhibitors) hauv cov tshuaj tsuag.
• Txwv tsis pub siv cov ntawv thov caij ntujYuav kom tsawg dua lossis sib npaug rau 3 kev kho mob ib lub voj voog kom txo tau kev xaiv siab.

Cov kev sib txuas tshiab muaj kev siv hlau peelaxyl kev ua haujlwm thaum tswj kev tiv thaiv:

• Hlaurayl - m (mefenoxam): Qhov kev ua kom muaj r - Entantiomer muab cov txiaj ntsig sib npaug ntawm qhov kev ua tau zoo sib luag, txhim kho ib puag ncig kev nyab xeeb.
• Hlauaxyl + Propamocarb: Ua ke hauv 60% raws li cov qauv, cov khub noPhytophthora capsiciHauv cov kua txob ntawm 630-720 g i / ha, outperforming ib qho khoom los ntawm 15-20%.
• Kev kho cov noob encapsulated: Qeeb {{- Tso cov txheej txheem txuas ntxiv rau 30 hnub tom qab rov tshwm sim, piv rau 15 hnub rau WP tsim.

Thaum muab cov tshuaj lom tsawg tsawg (cov lej feeb ld 50=669 mg / kg), hlaukasxyl yuav tsum ua tib zoo saib:

• Ntses / Dej Nkau Lub Neej: Tsawg toxicity (96H LC50 rau Trout: 100 mg / l) tab sis zam cov dej paug.
• Cov av pheej: Moderately txawb (KOC 30-300), nrog DT50 ntawm 19 hnub nyob rau hauv aerobic tej yam.
• Tus neeg teb xov tooj kev nyab xeeb: Siv cov khoom pab tiv thaiv (hnab looj tes, ntsej muag) thaum lub sijhawm sib xyaw / daim ntawv thov kom tiv thaiv daim tawv nqaij / qhov muag.

Hlau marhaxyl tseem ceeb rau kev tswj kab mob thaum siv cov tswv yim. Nws cov haujlwm ua haujlwm tawm tsam omycetes, nrog rau kev txhim kho cov qauv thiab cov qauv ntawm cov tuam tsev, ua kom pom tseeb nws txoj kev ua liaj ua teb kom ruaj khov. Farmers must balance its exceptional effectiveness against soil-borne and foliar pathogens with careful resistance management-protecting both current yields and long-term fungicide usefulness. Raws li ua liaj ua teb ua ke thiab kev nyab xeeb hloov cov kab mob muaj zog ua rau muaj lub luag haujlwm tseem ceeb hauv kev ua kom muaj cov zaub ua kom ruaj khov hauv cov zaub ua ke, cov txiv hmab txiv ntoo, thiab txiv hmab txiv ntoo.
