Posachedwapa, Rizobacter yatulutsa Rizoderma, mankhwala ophera bowa omwe amagwiritsidwa ntchito pochiza mbewu za soya ku Argentina, omwe ali ndi trichoderma harziana yomwe imaletsa matenda a bowa m'mbewu ndi m'nthaka.
Matias Gorski, woyang'anira zamoyo padziko lonse ku Rizobacter, akufotokoza kuti Rizoderma ndi mankhwala ophera tizilombo toyambitsa matenda omwe adapangidwa ndi kampaniyo mogwirizana ndi INTA (National Institute of Agricultural Technology) ku Argentina, omwe adzagwiritsidwa ntchito limodzi ndi mankhwala ophera tizilombo toyambitsa matenda.
"Kugwiritsa ntchito mankhwalawa musanabzale kumapangitsa kuti soya ikule bwino m'malo achilengedwe okhala ndi thanzi komanso otetezedwa, motero kumawonjezera zokolola m'njira yokhazikika komanso kukonza momwe nthaka imakulira," adatero.
Kuphatikiza kwa mankhwala ophera tizilombo toyambitsa matenda ndi mankhwala ophera tizilombo toyambitsa matenda ndi njira imodzi yatsopano kwambiri yogwiritsira ntchito soya. Kwa zaka zoposa zisanu ndi ziwiri zoyeserera m'munda komanso mayeso osiyanasiyana awonetsa kuti mankhwalawa amagwira ntchito bwino kuposa mankhwala omwe amagwiritsidwa ntchito mofanana. Kuphatikiza apo, mabakiteriya omwe ali mu mankhwalawa amagwirizana kwambiri ndi mitundu ina ya bowa yomwe imagwiritsidwa ntchito mu njira yochizira mbewu.
Chimodzi mwa ubwino wa njira imeneyi yachilengedwe ndi kuphatikiza njira zitatu zogwirira ntchito, zomwe mwachibadwa zimaletsa kubwereranso ndi kukula kwa matenda ofunikira kwambiri omwe amakhudza mbewu (fusarium wilt, simulacra, fusarium) ndikuletsa kuthekera kwa kukana tizilombo toyambitsa matenda.
Ubwino uwu umapangitsa kuti mankhwalawa akhale chisankho chabwino kwa opanga ndi alangizi, chifukwa matenda ochepa amatha kupezeka mutagwiritsa ntchito foliicide koyamba, zomwe zimapangitsa kuti kugwiritsa ntchito bwino kukhale bwino.
Malinga ndi Rizobacter, Rizoderma idachita bwino kwambiri m'mayesero akumunda komanso m'gulu la mayeso a kampaniyo. Padziko lonse lapansi, 23% ya mbewu za soya zimachiritsidwa ndi imodzi mwa mankhwala opangidwa ndi Rizobacter.
"Tagwira ntchito ndi opanga ochokera kumayiko 48 ndipo tapeza zotsatira zabwino kwambiri. Njira imeneyi yogwirira ntchito imatithandiza kuyankha zomwe akufuna ndikupanga ukadaulo wopangira katemera womwe ndi wofunikira kwambiri pakupanga," adatero.
Mtengo wogwiritsira ntchito majekeseni pa hekitala ndi US$4, pomwe mtengo wa urea, feteleza wa nayitrogeni wopangidwa m'mafakitale, ndi pafupifupi US$150 mpaka US$200 pa hekitala. Fermín Mazzini, mkulu wa Rizobacter Inoculants Argentina, adati: "Izi zikusonyeza kuti phindu la ndalama zomwe zayikidwa ndi zoposa 50%. Kuphatikiza apo, chifukwa cha thanzi labwino la mbewu, zokolola zapakati zitha kukwera ndi zoposa 5%. "
Pofuna kukwaniritsa zosowa zomwe zili pamwambapa, kampaniyo yapanga mankhwala oletsa chilala ndi kutentha kwambiri, omwe angatsimikizire kuti njira zochiritsira mbewu zikugwira ntchito bwino m'mikhalidwe yovuta komanso kuonjezera zokolola ngakhale m'madera omwe ali ndi mikhalidwe yochepa.
Ukadaulo wothira mankhwala otchedwa biological induction ndiye ukadaulo wapamwamba kwambiri wa kampaniyo. Biological induction imatha kupanga zizindikiro zama molekyulu kuti iyambe kagayidwe ka mabakiteriya ndi zomera, kulimbikitsa kupangika kwa tinthu tating'onoting'ono koyambirira komanso kogwira mtima, motero kukulitsa mphamvu ya nayitrogeni ndikulimbikitsa kuyamwa kwa michere yomwe imafunika ndi nyemba kuti zikule bwino.
"Timapatsa alimi mphamvu zonse zatsopano zopezera zinthu zochiritsira zokhazikika. Masiku ano, ukadaulo womwe umagwiritsidwa ntchito m'munda uyenera kukwaniritsa zomwe alimi akuyembekezera kuti apeze phindu, komanso kuteteza thanzi ndi mgwirizano wa chilengedwe chaulimi." Matías Gorski adamaliza.
