UMthethosivivinywa No. 32 woMnyango Wezokuvikelwa Kwezitshalo kanye Nezingeniso Zezolimo we-Secretariat for The Defence of Agriculture of Brazil, owashicilelwa ku-Official Gazette ngomhlaka-23 Julayi 2021, ubala izinhlobo ezingama-51 zezibulala-zinambuzane (imikhiqizo engasetshenziswa abalimi). Ishumi nesikhombisa lalawa malungiselelo kwakuyimikhiqizo engenamthelela omkhulu noma imikhiqizo esuselwe ku-bio.
Emikhiqizweni ebhalisiwe, emihlanu iqukethe izithako ezisebenzayo ezifike eBrazil okokuqala, emithathu iqukethe izithako ezisebenzayo zemvelaphi yezinto eziphilayo ezingasetshenziswa kwezolimo eziphilayo kanti emibili iqukethe izithako ezisebenzayo zemvelaphi yamakhemikhali.
Imikhiqizo emithathu emisha yezinto eziphilayo (I-Neoseiulus barkeri, i-S. chinensis, kanye ne-N. montane) zibhaliswe ngaphansi kwe-Reference Specification (RE) futhi zingasetshenziswa kunoma yiluphi uhlelo lokutshala.
I-Neoseiulus barkeri ingumkhiqizo wokuqala obhalisiwe eBrazil ukulawula i-Raoiella indica, inkathazo enkulu yezihlahla zikakhukhunathi. Umkhiqizo ofanayo osekelwe ekubhalisweni kwe-ER 45 unganconywa futhi ekulawuleni izimbuzane ezimhlophe.
UBruno Breitenbach, umxhumanisi jikelele wezibulala-zinambuzane nemikhiqizo ehlobene nazo, uchaze wathi: “Nakuba sinemikhiqizo yamakhemikhali yokulawula izibungu ezimhlophe esingakhetha kuzo, lo ngumkhiqizo wokuqala webhayoloji wokulawula lesi sinambuzane.”
I-Hua Glazed Wasp ewumuthi odla izimila yaba umkhiqizo wokuqala wezinto eziphilayo ngokusekelwe ekubhalisweni kwe-ER 44. Ngaphambi kwalokho, abalimi babenekhemikhali eyodwa kuphela eyayingasetshenziswa ukulawula i-Liriomyza sativae (Liriomyza sativae).
Ngokusekelwe ku-No. 46 Reference Regulations, umkhiqizo obhalisiwe wokulawula izinto eziphilayo i-Neoseiia mountain mites uyanconywa ukulawula i-Tetranychus urticae (Tetranychus urticae). Nakuba kuneminye imikhiqizo yezinto eziphilayo engalawula nalesi sinambuzane, lo mkhiqizo awuyona indlela engcono kakhulu.
Isithako esisebenzayo samakhemikhali esisanda kubhaliswai-cyclobromoximamideukuze kulawulwe izibungu ze-Helicoverpa armigera ezitshalweni zikakotini, ummbila kanye nobhontshisi. Lo mkhiqizo uphinde usetshenziswe ukulawula i-Leucoptera coffeella ezitshalweni zekhofi kanye ne-Neoleucinodes elegantalis kanye ne-Tuta Absolute ezitshalweni zikatamatisi.
Esinye isithako esisebenzayo samakhemikhali esibhalisiwe yi-fungicidei-isofetamid, esetshenziselwa ukulawula i-Sclerotinia sclerotiorum ezitshalweni zesoya, ubhontshisi, amazambane, utamatisi kanye nelethisi. Lo mkhiqizo unconywa futhi ukulawula i-Botrytis cinerea ku-anyanisi namagilebhisi kanye ne-Venturia inaequalis ezitshalweni zama-apula.
Eminye imikhiqizo isebenzisa izithako ezisebenzayo ezibhaliswe eShayina. Ukubhaliswa kwezibulala-zinambuzane ezijwayelekile kubaluleke kakhulu ukunciphisa ukuqongelela emakethe nokukhuthaza ukuncintisana, okuzoletha amathuba okuhweba afanele kanye nezindleko zokukhiqiza eziphansi kwezolimo zaseBrazil.
Yonke imikhiqizo ebhalisiwe ihlaziywa futhi ivunyelwe yiminyango ephethe ezempilo, ezemvelo kanye nezolimo ngokuhambisana nezindinganiso zesayensi kanye nemikhuba emihle yamazwe ngamazwe.
