Cov nroj tsuag kab mob (phytopathogens) ntawm cov qoob loo zaub mov yog ib qho kev txwv loj ntawm kev ua liaj ua teb thoob ntiaj teb. Cov phytopathogens no yog lub luag haujlwm rau cov qoob loo loj heev thaum lub sijhawm sau ua ntej, khaws cia thiab kev thauj mus los ntawm cov qoob loo. Nws tau kwv yees tias thoob ntiaj teb, 20-30% ntawm cov qoob loo poob txhua xyoo vim yog cov kab mob nroj tsuag.1 Ntawm cov phytopathogens, muaj ntau tshaj 200 hom phytobacteria.2 Txawm hais tias muaj ntau lub tswv yim tau siv los tswj cov phytopathogens, lawv tseem nyob ib puag ncig. kev sib tw rau kev ua liaj ua teb.
Cov tswv yim tswj kev siv ntau tshaj plaws yog cov tshuaj tua kab mob (piv txwv li, streptomycin) thiab cov khoom siv tooj liab. Txawm li cas los xij, kev siv tshuaj tua kab mob thoob plaws hauv kev ua liaj ua teb tau ua rau muaj kev hloov pauv ntawm cov tshuaj tua kab mob ntawm ntau phytopathogens. Streptomycin kuj tau pom nyob rau hauv erwinia, Pseudomonas thiab Xanthomonas ua spp. Cov tshuaj tiv thaiv kab mob (piv txwv li, strAB) nyob rau hauv cov phytopathogens no tuaj yeem raug hloov mus rau kab rov tav uas ua rau muaj kev sib kis ntawm cov tshuaj tua kab mob. Kev siv tooj liab tsis tu ncua ua rau nws cov khoom tsim nyob rau hauv ib puag ncig, uas tau txuas nrog tib neeg cov teeb meem kev noj qab haus huv, tshuaj lom rau cov nroj tsuag thiab fauna, thiab kev loj hlob ntawm tooj liab-tolerant phytopathogens. Tib neeg thiab tsiaj muaj kev txhawj xeeb txog kev noj qab haus huv uas tau cuam tshuam nrog tooj liab toxicity suav nrog kab mob plab, kab mob siab, kev xeeb tub thiab cov kab mob neurodegenerative xws li Alzheimer's disease. Indian mob cirrhosis thaum yau yog ib qho teeb meem uas tau txuas nrog kev noj cov tooj liab ntau hauv cov tib neeg uas muaj feem cuam tshuam txog caj ces. Copper-induced toxicity kuj tau tshaj tawm tias ua rau muaj peev xwm nce toj thiab nce kev tuag hauv Drosophila melanogaster. Cov tsos mob ntawm ntau tshaj tooj liab nyob rau hauv cov nroj tsuag muaj xws li kev loj hlob ntawm cov hauv paus hniav thiab tua, chlorosis, puas photosynthetic pigments thiab tej zaum yuav tuag.
Kev kis kab mob ntawm cov av nrog tooj liab puas cov xim photosynthetic thiab cuam tshuam nrog kev loj hlob thiab kev sib pauv roj ntawm peb cov zaub (Brassica alboglabra, Brassica chinensis: qhov no yog yuav ua li cas zoo dua monetize koj cov neeg tuaj saib thiab Chrysanthemum Coronarium). Copper oxide nanoparticles kuj tau pom los cuam tshuam rau tus nqi ntawm kev loj hlob, thiab kev loj hlob ntawm cov hauv paus hniav thiab tua ntawm lub caij nplooj ntoos hlav barley (Barley sativum distichum). Kev tiv thaiv rau tooj liab-based bactericides kuj yog ib qho kev sib tw hauv kev tswj cov phytopathogens. Copper kuj tau pom nyob rau hauv ntau yam phytopathogens suav nrog Pseudomonas thiab Xanthomonas spp.
Ib txoj kev tshawb fawb qhia tias 80% ntawm 35 Cov pob txha mos p.v. Phaseolicola Cov kab mob sib cais los ntawm snap taum teb nthuav tawm tsis kam rau tooj liab. Qhov no yog ib qho kev txhawj xeeb loj heev uas txiav txim siab tias daim ntawv thov tooj liab yog tam sim no thawj txoj hauv kev tswj rau cov phytopathogens. Ntau lub tebchaws tau txwv lossis txwv kev siv tooj liab-raws li cov nroj tsuag tiv thaiv. Yog li ntawd, cov tswv yim tswj tshiab tau raug txiav txim siab thiab kawm. Cov no suav nrog kev siv cov kab mob bacteriophages ua cov tshuaj tiv thaiv biocontrol.
Bacteriophages (phages) yog cov kab mob uas muaj peev xwm nthuav tawm hauv cov kab mob hauv cov kab mob. Qhov kev txaus siab ntawm phages li biocontrol agents yog ntaus nqi rau lawv cov yam tsis muaj tshuaj lom rau eukaryotic hlwb, tus kheej replication, tus tswv tsev tshwj xeeb, muaj peev xwm kov yeej tsis kam thiab yooj yim ntawm kev tsim khoom. Phage cocktails tshwj xeeb tam sim no ib qho kev xaiv siv tau rau kev nthuav dav phage host ntau yam, txwv qhov tshwm sim ntawm cov kab mob tsis zoo thaum tswj xyuas cov haujlwm lytic ntawm phages. Nws yog qhov tseem ceeb heev uas tus qauv siv los tsim phage cocktail yuav tsum ua rau muaj txiaj ntsig zoo tshaj plaws rau cov kab mob. Nws tseem yog ib qho tseem ceeb uas qee yam tseem ceeb tau txiav txim siab thaum lub sijhawm tsim thiab siv phage cocktail: lawv qhov ruaj khov, lub sijhawm tsim khoom thiab tus nqi ntawm cov cocktails nyuaj, muaj feem cuam tshuam rau cov kab mob uas tsis tau pom zoo, lub sij hawm ntawm phage daim ntawv thov, thiab kev pheej hmoo ntawm cov nroj tsuag. ib puag ncig. Kev soj ntsuam tas li yuav tsum tau ua kom ntseeg tau tias qhov ua tau zoo ntawm cov dej cawv muaj kev ruaj ntseg vim yog lub zog ntawm phages. Txawm hais tias phage cocktails raug suav hais tias yog lub tswv yim zoo ntawm biocontrol ntawm phytobacteria, kev tshawb fawb ntxiv yuav tsum tau ua kom nkag siab txog kev sib cuam tshuam ntawm phages thiab cov kab mob hauv cov nroj tsuag ib puag ncig, thiab kom kov yeej cov teeb meem kev txawj ntse.
