Dab tsi yog hom fungicides?
Cov fungicides feem ntau muab faib ua kev ua liaj ua teb fungicides thiab industrial fungicides.
Agricultural fungicides yog cov tshuaj tua kab siv los tswj cov kab mob uas tshwm sim los ntawm ntau yam kab mob pathogenic, feem ntau xa mus rau fungicides. Tab sis thoob ntiaj teb, nws feem ntau yog siv los ua cov lus dav dav rau cov tshuaj uas tswj ntau yam kab mob pathogenic.
Raws li kev ua kom tsis muaj menyuam, cov kab mob fungicides tuaj yeem muab faib ua oxidative fungicides thiab non-oxidative fungicides. Oxidative bactericides feem ntau muaj zog oxidants, uas feem ntau ua tiav lub hom phiaj ntawm kev ua kom tsis muaj menyuam los ntawm oxidizing nrog metabolic enzymes hauv cov kab mob. Non-oxidizing bactericides hais txog cov tshuaj lom uas ua rau tshwj xeeb ntawm cov kab mob, yog li rhuav tshem cov hlwb lossis cov kab mob nyob hauv lub cev, thiab ua tiav cov kab mob bactericidal.
Dab tsi yog qhov txawv ntawm cov kab mob bactericide thiab cov kab mob bacteriostatic?
Lub hauv paus chiv keeb ntawm cov khoom siv tshuaj tua kab mob tau siv txij li thaum ub, nws tuaj yeem khaws kev loj hlob lossis kev tsim tawm ntawm qee yam kab mob (kab mob, fungi, poov xab, algae thiab kab mob, thiab lwm yam) hauv qab no tsim nyog rau qee lub sijhawm.
Cov tshuaj tua kab mob thiab cov kab mob bacteriostatic muaj ntau hom kev ua haujlwm. Cov kab mob bacteriostatic ua haujlwm los ntawm inhibiting kab mob kev loj hlob; bactericides rhuav tshem cov kab mob ntawm tes thiab ua rau cov kab mob tuag (xws li -lactams).
Qhov tseeb, tsis muaj kev txwv rau bactericidal lossis bacteriostatic. Ntawm qhov siab dua, qee cov kab mob bacteriostatic kuj muaj cov kab mob bactericidal.
Qhov sib txawv ntawm cov kab mob bactericides thiab cov kab mob bacteriostatic zoo li tau ua sim. Hauv kev sim yooj yim, xws li txoj kev disk, tom qab 24 teev ntawm incubation, cov tshuaj uas muaj disk raug tshem tawm thiab incubation txuas ntxiv mus. Yog hais tias cov kab mob nyob rau hauv cheeb tsam ntawm inhibition re-loj hlob, nws yog pom raws li bacteriostatic, yog hais tias tsis muaj re-loj hlob, nws yog qhia raws li bactericide.
Lub luag haujlwm ntawm fungicides
Cov fungicides, tseem hu ua biocides, fungicides thiab algaecides, microbicides, thiab lwm yam, feem ntau yog hais txog cov tshuaj uas muaj peev xwm tswj tau zoo los yog tua cov kab mob hauv cov dej - kab mob, fungi thiab algae.
Kev tswj cov kab mob nroj tsuag nrog fungicides yog ib txoj hauv kev zoo. Biocides muaj ob hom kev ua: tiv thaiv fungicides thiab kab mob fungicides. Raws li lub hauv paus ntawm fungicides, ntxiv rau cov tshuaj tua kab mob ua liaj ua teb uas muaj cov kab mob fungicides, cov hom tseem ceeb yog tshuaj tua kab mob fungicides, uas yog cov tshuaj siv los tswj cov kab mob nroj tsuag. Muaj ntau ntau yam laj thawj vim li cas fungicides tuaj yeem ua rau phytotoxicity. Cov tshuaj tua kab nws tus kheej, qhov sib txawv rhiab heev ntawm cov qoob loo, theem kev loj hlob ntawm cov qoob loo, thiab climatic tej yam kev mob yuav muaj kev cuam tshuam rau nws.
