Rizobacter yatangije bio-imbuto yo kuvura fungiside Rizoderma muri Arijantine

Vuba aha, Rizobacter yashyize ahagaragara Rizoderma, umuti wica udukoko twa soya muri Arijantine, urimo trichoderma harziana irwanya udukoko twangiza mu mbuto no mu butaka.

Matias Gorski, ushinzwe ubuzima ku isi muri Rizobacter, asobanura ko Rizoderma ari umuti wica udukoko mu buryo bw’ibinyabuzima wakozwe n’ikigo ku bufatanye na INTA (Ikigo cy’Igihugu cy’Ikoranabuhanga mu by’Ubuhinzi) muri Arijantine, uzakoreshwa hamwe n’umuti ukoreshwa mu gutera udukoko.

Yagize ati: “Gukoresha uyu musaruro mbere yo kubiba bitanga uburyo bwo gukura neza mu bidukikije bifite intungamubiri kandi birinzwe, bityo bikongera umusaruro mu buryo burambye kandi bikanoza imiterere y’ubutaka.”

Guhuza imiti itera inshinge n'imiti itera inshinge ni bumwe mu buryo bushya bwo kuvura soya. Imyaka irenga irindwi y'igerageza mu murima n'urusobe rw'igerageza byagaragaje ko umusaruro ukora neza cyangwa neza kurusha imiti ikoreshwa mu buryo bumwe. Byongeye kandi, bagiteri ziri muri iyo miti zihura cyane na zimwe mu bwoko bw'imiti ikoreshwa mu kuvura imbuto.

Imwe mu nyungu z'ubu buryo bw'ibinyabuzima ni uruvange rw'uburyo butatu bwo gukora, butuma indwara zikomeye zigira ingaruka ku bihingwa (fusarium wilt, simulacra, fusarium) zidasubira no kwiyongera, kandi bugatuma habaho ubudahangarwa bw'udukoko.

Iyi nyungu ituma iki gicuruzwa kiba amahitamo y’ingenzi ku bakora n’abajyanama, kuko indwara zishobora kugabanuka nyuma yo gukoresha foliicide bwa mbere, bigatuma imikorere myiza yo kugikoresha irushaho kuba myiza.

Nk’uko Rizobacter ibivuga, Rizoderma yitwaye neza mu igeragezwa ryo mu murima no mu igerageza ry’isosiyete. Ku isi yose, 23% by’imbuto za soya zivurwa hakoreshejwe imwe mu miti yakozwe na Rizobacter.

Yagize ati: “Twakoranye n’inganda zikomoka mu bihugu 48 kandi twageze ku musaruro mwiza cyane. Ubu buryo bwo gukora butuma dushobora gusubiza ibyo zisaba no guteza imbere ikoranabuhanga ryo gutera inshinge rifite akamaro kanini mu musaruro.”

Igiciro cyo gukoresha imiti itera indwara kuri hegitari ni amadolari 4 y'Amerika, mu gihe ikiguzi cya urea, ifumbire mvaruganda ya azote, kiri hagati y'amadolari 150 na 200 y'Amerika kuri hegitari. Fermín Mazzini, ukuriye Rizobacter Inoculants Argentina, yavuze ati: “Ibi bigaragaza ko inyungu ku ishoramari irenga 50%. Byongeye kandi, bitewe n’uko umusaruro w’ibihingwa urushaho kuba mwiza, umusaruro mpuzandengo ushobora kwiyongeraho ibirenze 5%.

Kugira ngo igere ku musaruro ukenewe, iyi sosiyete yakoze umuti ukingira amapfa n'ubushyuhe bwinshi, ushobora kwemeza ko imbuto zivurwa neza mu bihe bikomeye kandi wongere umusaruro w'ibihingwa ndetse no mu turere dufite imiterere mike.

Ikoranabuhanga ryo gutera ibiti ryitwa biological induction ni ryo koranabuhanga rigezweho cyane ry’ikigo. Biological induction ishobora gutanga ibimenyetso bya molekile kugira ngo ikore imikorere ya bagiteri n’ibimera, itere imbere kandi ikora neza kurushaho, bityo ikongera ubushobozi bwo gufata azote no guteza imbere uburyo intungamubiri zikenerwa n’ibinyamisogwe kugira ngo bikure neza.

Matías Gorski yasoje agira ati: “Duha abahinzi ibikoresho bishya mu buryo burambye. Muri iki gihe, ikoranabuhanga rikoreshwa mu buhinzi rigomba kuba rishobora guhaza ibyo abahinzi biteze ku musaruro, ndetse no kurinda ubuzima n’uburinganire bw’urusobe rw’ubuhinzi.”
