Maererano nenhau kubva kuBarcelona, Spain, shizha rinopisa, iro rinopararira pasi rose uye rinokonzera kurasikirwa kukuru kwehupfumi uye kuisa pangozi zvirimwa zvakasiyana-siyana, rinotarisirwa kudzorwa. Dhipatimendi reDevelopment reSpain lainco kambani uye iyo yekudyara hutano hunyanzvi uye nzvimbo yekusimudzira yeYunivhesiti yeHelona (cidsv) yakabudirira kuburitsa yakachena yakasikwa mhinduro mushure memakore mashanu ekutsvagisa kwesainzi. Ichi chirongwa hachingogone kudzora zvinobudirira uye kudzivirira mashizha ekupisa, asi zvakare ane chekuita kune zvimwe zvirwere zvebhakitiriya zvinoisa zvirimwa munjodzi, senge Pseudomonas syringae chirwere che kiwifruit nematomatisi, Xanthomonas chirwere chematombo emuchero nemuti wemuarumondi, pear fire blight uye zvichingodaro. .
Leaf edge Scorch inoonekwa seimwe yezvirwere zvinokuvadza zvirimwa, kunyanya miti yemichero. Inogona kukonzera kusvava kwekudyara uye kuora. Mune zvimwe zviitiko zvakakomba, zvinotungamirira pakuomeswa kwemashizha emiti nematavi kusvikira mbeu yose yafa. Kare, nzira yekudzora shizha kumucheto kutsva kwaiwanzobvisa zvakananga uye kuparadza zvirimwa zvese zvinorwara munzvimbo yekudyara kudzivirira kupararira kunoramba kuripo kwebhakitiriya. Zvisinei, nzira iyi haigoni kudzivirira zvachose kupararira kwepasi rose kweshizha kumucheto kunopisa pathogen. Zvinonzi chirwere ichi chirimwa chakapararira muAmerican continent, Middle East, Asia neEurope. Zvirimwa zvinokuvadza zvinosanganisira muzambiringa, muorivhi, muti wemichero wematombo, muarumondi, muti wecitrus nemimwewo miti yemichero, izvo zvaunzawo kurasikirwa kukuru kweupfumi. Zvinofungidzirwa kuti muCalifornia, USA, munongova nechikamu chimwe chete chemazambiringa, izvo zvinoita kuti vanhu varasikirwe nemadhora mamiriyoni zana nemana gore rega rega nekuda kwekutsva kwemashizha. Kubva kuwanikwa kwekutsva kwemashizha muEurope muna 2013, nekuda kwekupararira kwayo nekukurumidza, pathogen yakanyorwa sechirongwa chakakosha chekuvharisa zvipembenene neEuropean neMediterranean Plant Protection Organisation (EPPO). Zvidzidzo zvakakodzera muEurope zvinoratidza kuti pasina kudzivirira kunoshanda uye matanho ekudzora, chirwere cheshizha chinopisa mubindu remuorivhi chinopararira zvisingaite, uye zvinofungidzirwa kuti kurasikirwa kwehupfumi kunogona kunge kwakakwira semabhiriyoni emaeuro mukati memakore makumi mashanu.
Sekambani yeR & D uye yekugadzira inotarisana nekuchengetedzwa kwezvirimwa, lainco muSpain yakazvipira kutsvaga mhinduro yechisikigo yekugadzirisa kupararira kweshizha rinopisa pasi rose kubvira 2016. Kubva pakudzidza kwakadzama kwechimwe chirimwa chechisikigo chakakosha. mafuta, lainco R & D dhipatimendi akatanga kuedza kushandisa Eucalyptus zvinokosha oiri kubata shizha kumucheto kunopisa utachiona, uye akawana migumisiro yakanaka. Mushure meizvozvo, iyo chirimwa chehutano innovation uye nzvimbo yekusimudzira yeHelona University (cidsv), inotungamirwa naDr. Emilio Montesinos, yakatanga mapurojekiti akakodzera ekubatana akatarisana neEucalyptus mafuta akakosha ekutsvagisa nekusimudzira, akasimbisazve kushanda kwechigadzirwa chemafuta akakosha, uye yakamhanyisa chirongwa kubva murabhoritari kuenda kune inoshanda yekushandisa. Uye zvakare, lainco yakasimbisa kuburikidza neyakatevedzana yekuedza kuti mhinduro yechisikigo iyi yakakodzerawo kudzora kupararira kwePseudomonas syringae chirwere chekiwifruit nematomatisi, Xanthomonas chirwere chematombo emuchero nemuarumondi uye pear fire blight yataurwa pamusoro apa.
Chinhu chakakosha cheiyi mhinduro yekuvandudza ndechekuti inzira yakachena yekudzora uye yekudzivirira, iri nyore kuita, uye hapana kukuvadzwa kuzvirimwa zvinorwara nemhuka nezvirimwa zvine hukama. Iko kuumbwa kwechigadzirwa kwakagadzikana pahupamhi hwepamusoro uye tembiricha yekamuri, uye ine mhedzisiro inoshamisa mukudzivirira pathogenic bhakitiriya hutachiona. Zvinonzi lainco's natural fungicide ichangobva kuwana chigadzirwa patent kuSpain uye ichasimudzirwa uye kushandiswa pasi rose mumwedzi mishomanana. Kutanga kubva 2022, lainco ichatanga kuita kunyoresa uye kubvumidza maitiro muUnited States neEuropean Union, iyo yakatangwa mune dzimwe nyika muSouth America.
Lainco ikambani yemakemikari inogadzira, inogadzira, inotakura uye inotengesa phytosanitary uye mishonga yemishonga. Parizvino, kambani ine dzakasiyana siyana dzekudzivirira zvirimwa, kunyanya iyo itsva biostimulant uye biological fetiraiza mhinduro. Panguva imwecheteyo, kambani inovimbisa inoshanda uye yakagadzikana yekusimudzira modhi ine mhando yechigadzirwa, hunyanzvi hwekuvandudza tekinoroji uye kuremekedza nharaunda.
