Munguva pfupi yapfuura, Rizobacter yakatanga Rizoderma, mushonga wekuuraya fungus unorwisa mbeu dzesoya muArgentina, une trichoderma harziana inodzora hutachiona hwefungus mumbeu nemuvhu.
Matias Gorski, maneja wezvemhuka pasi rose kuRizobacter, anotsanangura kuti Rizoderma mushonga wekuuraya fungi wakagadzirwa nekambani iyi pamwe chete neINTA (National Institute of Agricultural Technology) muArgentina, uyo uchashandiswa pamwe chete nezvigadzirwa zvemajekiseni.
"Kushandisa chigadzirwa ichi usati wadyara kunoita kuti soya dzikure munzvimbo ine hutano uye yakachengetedzwa, nokudaro zvichiwedzera goho nenzira inochengetedza nharaunda uye zvichivandudza mamiriro ekugadzirwa kwevhu," akadaro.
Kusanganiswa kwemishonga inobaya ne biocides ndeimwe yemishonga mitsva inoshandiswa pakurapa soya. Kwemakore anopfuura manomwe ekuyedza mumunda uye network yemiedzo yakaratidza kuti chigadzirwa ichi chinoshanda zvakanaka kana zviri nani pane makemikari nechinangwa chimwe chete. Pamusoro pezvo, mabhakitiriya ari muinoculum anowirirana zvakanyanya nemamwe marudzi efungus anoshandiswa mufomura yekurapa mbeu.
Chimwe chezvakanakira zveizvi biologic kusanganiswa kwemaitiro matatu, izvo zvinodzivirira kudzoka uye kukura kwezvirwere zvinonyanya kukanganisa zvirimwa (fusarium wilt, simulacra, fusarium) uye zvinodzivisa mukana wekusagona kudzivirira hutachiona.
Izvi zvinoita kuti chigadzirwa ichi chive sarudzo yakanaka kune vagadziri nevapi vezano, sezvo huwandu hwezvirwere hunogona kudzikira mushure mekushandisa foliicide kekutanga, zvichikonzera kuvandudzwa kwekushanda zvakanaka kwekushandisa.
Rizobacter inoti Rizoderma yakaita zvakanaka mumiedzo yemumunda uye mumakambani ekuedza. Pasi rose, 23% yembeu dzesoya dzinorapwa neimwe yemishonga inopinzwa yakagadzirwa neRizobacter.
"Takashanda nevagadziri vanobva kunyika makumi mana nemasere uye takawana mhedzisiro yakanaka kwazvo. Nzira iyi yekushanda inotibvumira kupindura zvinodiwa zvavo uye kugadzira matekinoroji ekubaiwa majekiseni akakosha pakugadzira," akadaro.
Mari yekushandisa mishonga inopinza pahekita imwe chete iUS$4, nepo mutengo weurea, fetiraiza yenitrogen inogadzirwa mumaindasitiri, iri pakati peUS$150 neUS$200 pahekita imwe chete. Fermín Mazzini, mukuru weRizobacter Inoculants Argentina, akataura kuti: “Izvi zvinoratidza kuti mari inowanikwa inodarika 50%. Pamusoro pezvo, nekuda kwekuvandudzika kwekudya kwezvirimwa, goho repakati rinogona kuwedzerwa neanopfuura 5%.
Kuti zvizadzise zvinodiwa pakugadzira zvataurwa pamusoro apa, kambani iyi yakagadzira mushonga unorwisa kusanaya kwemvura uye kupisa kwakanyanya, izvo zvinogona kuona kuti kurapwa kwembeu kunoshanda zvakanaka mumamiriro ezvinhu akaoma uye kuwedzera goho rezvirimwa kunyangwe munzvimbo dzine mamiriro ezvinhu mashoma.
Tekinoroji yekubaya inonzi biological induction ndiyo tekinoroji itsva yekambani. Biological induction inogona kugadzira masaini emasero kuti iite kuti mabhakitiriya nemiti zvishande, kukurudzira kuumbwa kwematumbu nekukurumidza uye zvinobudirira, nokudaro zvichiwedzera kugona kwenitrogen fixation uye kukurudzira kunwa kwezvinovaka muviri zvinodiwa nembeu kuti zvikure zvakanaka.
"Tinopa mukana wakazara wekugona kwedu kuvandudza varimi zvigadzirwa zvekurapa zvinogara kwenguva refu. Nhasi uno, tekinoroji inoshandiswa mumunda inofanirwa kukwanisa kusangana nezvinodiwa nevarimi kuti vawane goho, ukuwo ichichengetedza hutano nekuenzana kwenzvimbo yekurima." Matías Gorski akapedzisa.
