Muva nje, iRizobacter yethule iRizoderma, umuthi wokubulala amagciwane we-biofungicide wokwelapha imbewu yesoya e-Argentina, oqukethe i-trichoderma harziana elawula amagciwane esikhunta embewini nasenhlabathini.
UMatias Gorski, umphathi wezinto eziphilayo emhlabeni wonke eRizobacter, uchaza ukuthi iRizoderma iyi-fungicide yokwelapha imbewu yemvelo eyakhiwe yinkampani ngokubambisana ne-INTA (National Institute of Agricultural Technology) e-Argentina, ezosetshenziswa kanye nomugqa womkhiqizo wokugoma.
“Ukusebenzisa lo mkhiqizo ngaphambi kokuhlwanyela kudala izimo zokuba ubhontshisi ukhule endaweni yemvelo enomsoco nevikelwe, ngaleyo ndlela kwandiswe isivuno ngendlela eqhubekayo futhi kuthuthukiswe izimo zokukhiqizwa kwenhlabathi,” kusho yena.
Ukuhlanganiswa kwezitofu kanye ne-biocides kungenye yezindlela ezintsha zokwelapha ezisetshenziswa kubhontshisi. Iminyaka engaphezu kweyisikhombisa yokuhlolwa kwensimu kanye nenethiwekhi yezivivinyo kukhombisile ukuthi umkhiqizo usebenza kahle noma kangcono kunamakhemikhali ngenhloso efanayo. Ngaphezu kwalokho, amabhaktheriya akulesi sitofu ahambisana kakhulu nezinye izinhlobo zesikhunta ezisetshenziswa kufomula yokwelapha imbewu.
Enye yezinzuzo zalokhu kuhlanganiswa kwezindlela ezintathu zokusebenza, okuvimbela ngokwemvelo ukuphindaphinda nokuthuthukiswa kwezifo ezibaluleke kakhulu ezithinta izitshalo (i-fusarium wilt, i-simulacra, i-fusarium) futhi kuvimbela amathuba okumelana nezifo.
Le nzuzo yenza umkhiqizo ube ukukhetha okuhlakaniphile kwabakhiqizi kanye nabeluleki, njengoba amazinga aphansi esifo angatholakala ngemuva kokusetshenziswa kokuqala kwe-foliicide, okuholela ekusebenzeni kahle kokusetshenziswa okuthuthukisiwe.
Ngokusho kweRizobacter, iRizoderma yenze kahle ezivivinyweni zasensimini kanye nasenethiwekhi yezilingo zenkampani. Emhlabeni wonke, ama-23% embewu kabhontshisi aphathwa ngenye yezitofu ezakhiwe yiRizobacter.
“Sisebenzisane nabakhiqizi abavela emazweni angu-48 futhi sithole imiphumela emihle kakhulu. Le ndlela yokusebenza isenza sikwazi ukuphendula ezidingweni zabo futhi sithuthukise ubuchwepheshe bokugoma obubaluleke kakhulu ekukhiqizeni,” kusho yena.
Izindleko zokufaka izitofu ngehekthare ngalinye zingama-US$4, kanti izindleko ze-urea, umanyolo we-nitrogen okhiqizwa ezimbonini, zingama-US$150 kuya kuma-US$200 ngehekthare ngalinye. UFermín Mazzini, inhloko yeRizobacter Inoculants Argentina, ukhombe: “Lokhu kukhombisa ukuthi imbuyiselo yokutshalwa kwezimali ingaphezu kwama-50%. Ngaphezu kwalokho, ngenxa yesimo sokudla esithuthukisiwe sesitshalo, isivuno esimaphakathi singakhushulwa ngaphezu kwama-5%.
Ukuze kuhlangatshezwane nezidingo zokukhiqiza ezingenhla, inkampani isungule umuthi wokugomela omelana nesomiso kanye nokushisa okuphezulu, ongaqinisekisa ukusebenza kahle kokwelashwa kwembewu ngaphansi kwezimo ezinzima futhi wandise isivuno ngisho nasezindaweni ezinezimo ezilinganiselwe.
Ubuchwepheshe bokugoma obubizwa ngokuthi i-biological induction buwubuchwepheshe obusha kakhulu benkampani. I-biological induction ingakhiqiza izimpawu zama-molecule ukuze kusebenze izinqubo ze-metabolic zamabhaktheriya nezitshalo, ikhuthaze ukwakheka kwamaqhubu kusenesikhathi futhi kuphumelele kakhudlwana, ngaleyo ndlela ikhulise ikhono lokufakwa kwe-nitrogen futhi ikhuthaze ukumuncwa kwezakhamzimba ezidingekayo yizimila ukuze zichume.
“Sisebenzisa ngokugcwele ikhono lethu lokuqamba izinto ezintsha lokuhlinzeka abalimi ngemikhiqizo yokwelapha eqhubekayo. Namuhla, ubuchwepheshe obusetshenziswa ensimini kumele bukwazi ukuhlangabezana nokulindelwe ngabalimi ukuze bathole isivuno, kuyilapho futhi buvikela impilo kanye nokulinganisela kohlelo lwezolimo.”
