UMthethosivivinywa Nombolo 32 woMphathiswa woKhuseleko lweZityalo kunye neeNgeniso zezoLimo weSebe lezoKhuseleko lwezoLimo laseBrazil, opapashwe kwiGazethi esemthethweni ngomhla wama-23 kweyeKhala ngo-2021, udwelisa iindlela ezingama-51 zokuxuba izibulali-zinambuzane (iimveliso ezinokusetyenziswa ngabalimi). Ishumi elinesixhenxe kwezi zinto zokulungiselela yayiziimveliso ezingenampembelelo ingako okanye iimveliso ezisekelwe kwibhayoloji.
Kwiimveliso ezibhalisiweyo, ezintlanu ziqulathe izithako ezisebenzayo ezifike eBrazil okokuqala, ezintathu ziqulathe izithako ezisebenzayo zebhayoloji ezinokusetyenziswa kwezolimo oluphilayo kwaye ezimbini ziqulathe izithako ezisebenzayo zemvelaphi yeekhemikhali.
Iimveliso ezintathu ezintsha zebhayoloji (UNeoseiulus barkeri, S. chinensis, kunye neN. montane) zibhalisiwe phantsi kweReference Specification (RE) kwaye zingasetyenziswa nakweyiphi na inkqubo yezityalo.
I-Neoseiulus barkeri yimveliso yokuqala ebhalisiweyo eBrazil yokulawula iRaoiella indica, izinambuzane eziphambili zemithi yekhokhonathi. Imveliso efanayo esekelwe kubhaliso lwe-ER 45 ingacetyiswa nokulawula iincukuthu ezimhlophe.
UBruno Breitenbach, umququzeleli jikelele wezibulali-zinambuzane kunye neemveliso ezinxulumene noko, ucacisile wathi: “Nangona sineemveliso zeekhemikhali zokulawula iincukuthu ezimhlophe esinokukhetha kuzo, le yimveliso yokuqala yebhayoloji yokulawula esi sinambuzane.”
I-Hua Glazed Wasp ene-parasitic wasp yaba yimveliso yokuqala yebhayoloji ngokusekelwe kubhaliso lwe-ER 44. Ngaphambi koko, abalimi babenekhemikhali enye kuphela eyayinokusetyenziswa ukulawula i-Liriomyza sativae (Liriomyza sativae).
Ngokusekelwe kwiMithetho yeNgxelo yeNombolo 46, imveliso yokulawula izinto eziphilayo ebhalisiweyo iNeoseiia mountain mites iyacetyiswa ukulawula iTetranychus urticae (Tetranychus urticae). Nangona kukho ezinye iimveliso zezinto eziphilayo ezinokulawula esi sinambuzane, le mveliso ayisiyonto ingenampembelelo ingako.
Isithako esisebenzayo sekhemikhali esisandula ukubhaliswai-cyclobromoximamideukuze kulawulwe iimbungu zeHelicoverpa armigera kwizityalo zomqhaphu, umbona kunye nesoya. Le mveliso ikwasetyenziselwa ukulawula iLeucoptera coffeella kwizityalo zekofu kunye neNeoleucinodes elegantalis kunye neTuta Absolute kwizityalo zetamatato.
Esinye isithako esisebenzayo sekhemikhali esibhalisiweyo yi-fungicidei-isofetamid, isetyenziselwa ukulawula iSclerotinia sclerotiorum kwizityalo zesoya, iimbotyi, iitapile, iitumato kunye nelettuce. Le mveliso ikwacetyiswa ukulawula iBotrytis cinerea kwi-Onions kunye neediliya kunye neVenturia inaequalis kwizityalo zeapile.
Ezinye iimveliso zisebenzisa izithako ezisebenzayo ezibhalisiweyo eTshayina. Ukubhaliswa kwezibulali-zinambuzane eziqhelekileyo kubaluleke kakhulu ukunciphisa uxinaniso lwemarike nokukhuthaza ukhuphiswano, oluya kuzisa amathuba orhwebo afanelekileyo kunye neendleko eziphantsi zemveliso kwezolimo zaseBrazil.
Zonke iimveliso ezibhalisiweyo ziyahlalutywa kwaye zivunyiwe ngamasebe ajongene nempilo, okusingqongileyo kunye nezolimo ngokuhambelana nemigangatho yesayensi kunye neendlela ezilungileyo zamazwe ngamazwe.
