Ngokutsho kweendaba ezivela eBarcelona, eSpain, i-leaf edge scorch, esasazeke ngokubanzi kwihlabathi jikelele kwaye ibangela ilahleko enkulu yezoqoqosho kwaye ibeka engozini iintlobo zezityalo, kulindeleke ukuba ilawulwe. Isebe loPhuhliso lwaseSpain inkampani ye-lainco kunye neziko lokusungula impilo yezityalo kunye neziko lophuhliso lweYunivesithi yase-helona (cidsv) iqalise ngempumelelo isisombululo esicocekileyo sendalo emva kweminyaka emihlanu yophando lwezenzululwazi. Esi sicwangciso asikwazi kuphela ukulawula ngokufanelekileyo kwaye sithintele ukutshisa kweqabunga, kodwa sibe nefuthe kwezinye izifo zebhaktheriya ezibeka engozini izityalo, ezifana nesifo se-Pseudomonas syringae se-kiwifruit kunye ne-tomato, isifo se-Xanthomonas sesiqhamo samatye kunye nomthi we-almond, i-pear fire blight njalo njalo. .
ILeaf edge Scorch ithathwa njengenye yezona ntsholongwane ziyingozi kwizityalo, ngakumbi kwimithi yeziqhamo. Ingakhokelela ekubuneni kwezityalo kunye nokubola. Kwiimeko ezimandundu, kuya kukhokelela ekomisweni kwamagqabi esityalo kunye namasebe de isityalo sife. Ngaphambili, indlela yokulawula ukutshisa kweqabunga yayiqhele ukususa ngokuthe ngqo kwaye itshabalalise zonke izityalo ezinesifo kwindawo yokutyala ukuthintela ukusasazeka okuqhubekayo kweebhaktheriya. Nangona kunjalo, le ndlela ayinakunqanda ngokupheleleyo ukusasazeka kwe-leaf edge scorch pathogen. Kuxelwa ukuba le pathogen yesityalo isasazeke ngokubanzi kwilizwekazi laseMelika, kuMbindi Mpuma, eAsia naseYurophu. Izityalo eziyingozi ziquka umdiliya, umthi womnquma, umthi weziqhamo zamatye, um-amangile, umthi wesitrasi neminye imithi yeziqhamo, nto leyo eye yazisa ilahleko enkulu kwezoqoqosho. Kuqikelelwa ukuba lunye kuphela udidi lomdiliya eCalifornia, eMelika, olubangela ilahleko ye-104 yezigidi zeedola zaseMelika minyaka le ngenxa yokutshisa kwamagqabi. Ukususela ekufunyanweni kwe-leaf edge scorch eYurophu ngo-2013, ngenxa yokusasazeka ngokukhawuleza, i-pathogen idweliswe njengeprojekthi engundoqo yokuvalela i-quarantine yi-European and Mediterranean Plant Protection Organisation (EPPO). Izifundo ezifanelekileyo eYurophu zibonisa ukuba ngaphandle kwamanyathelo othintelo kunye nolawulo olusebenzayo, i-pathogen yegqabi elitshisayo kwizitiya zomnquma iya kusasazeka ngokungathandekiyo, kwaye kuqikelelwa ukuba ilahleko yezoqoqosho inokuba phezulu njengeebhiliyoni zee-euro kwiminyaka engama-50.
Njenge-R & D kunye nenkampani yokuvelisa egxile ekukhuselweni kwezityalo, i-lainco e-Spain iye yazibophelela ekuhloleni isisombululo sendalo sokujongana nokwanda kwe-leaf edge scorch emhlabeni jikelele ukususela ngo-2016. Ngokusekelwe kuphando olunzulu lwesityalo esithile sendalo esibalulekileyo. oyile, lainco R & D isebe waqalisa ukuzama ukusebenzisa Eucalyptus ioli ebalulekileyo ukujongana amagqabi edge ibhaktheriya ezitshisayo, kwaye iphumelele iziphumo ezilungileyo. Emva koko, iziko lempilo yezityalo ezintsha kunye neziko lophuhliso lweYunivesithi yaseHelona (cidsv), ekhokelwa nguGqr Emilio Montesinos, yasungula iiprojekthi zentsebenziswano ezifanelekileyo ezigxininise kwi-oyile ye-Eucalyptus ebalulekileyo yophando kunye nophuhliso, ngakumbi ukuzimisela ukusebenza kwemveliso yeoli efunekayo, kwaye ikhawulezise iprojekthi ukusuka kwilabhoratri ukuya kwisicelo esisebenzayo. Ukongeza, i-lainco iqinisekisile ngoluhlu lwezilingo ukuba esi sisombululo sendalo sikwafanelekile ukulawula ukusasazeka kwesifo se-Pseudomonas syringae se-kiwifruit kunye ne-tomato, isifo se-Xanthomonas seziqhamo zamatye kunye nomthi we-almond kunye ne-pear fire blight ekhankanywe ngasentla.
Ingongoma ephambili yesi sisombululo sintsha kukuba yindlela ecocekileyo yokulawula kunye nokuthintela indalo, ekulula kakhulu ukuyiphumeza, kwaye akukho monakalo kwizityalo ezigulayo kunye nezilwanyana kunye nezityalo ezinxulumene nazo. Ukubunjwa kwemveliso kuzinzile ekugxininiseni okuphezulu kunye nokushisa kwegumbi, kwaye kunempembelelo ephawulekayo ekukhuseleni ukusuleleka kwebhaktheriya ye-pathogenic. Kuxelwe ukuba isichiza sokungunda sendalo se-lainco sisandula kufumana ilungelo elilodwa lomenzi wemveliso e-Spain kwaye siya kukhuthazwa kwaye sisetyenziswe kwihlabathi jikelele kwiinyanga ezimbalwa. Ukususela ngo-2022, i-lainco iya kuqala ukuqhuba inkqubo yokubhalisa kunye nokuvunywa e-United States kunye ne-European Union, eqaliswe kwamanye amazwe eMzantsi Melika.
I-Lainco yinkampani yeekhemikhali ephuhlisa, ivelise, ipakishe kwaye ithengise iimveliso ze-phytosanitary kunye neyeza. Okwangoku, inkampani inoluhlu olubanzi lwezisombululo zokukhusela izityalo, ngakumbi izisombululo ze-biostimulant kunye nezichumisi zebhayoloji. Ngelo xesha, inkampani iqinisekisa imodeli yophuhliso olusebenzayo kunye noluzinzileyo kunye nomgangatho wemveliso, ukuveliswa kwezinto ezintsha zobuchwepheshe kunye nentlonipho yokusingqongileyo.
