ʻO ka Bila Helu 32 o ke Kuhina o ka Palekana Mea Kanu a me nā Mea Hoʻokomo Mahiʻai o ke Kakauolelo no ka Palekana o ka Mahiʻai o Brazil, i paʻi ʻia ma ka Gazette Official ma ka lā 23 Iulai 2021, ua papa inoa i 51 mau ʻano hana pesticide (nā huahana hiki ke hoʻohana ʻia e nā mahiʻai). ʻO ka ʻumikumamāhiku o kēia mau hoʻomākaukau he mau huahana hopena haʻahaʻa a i ʻole nā huahana bio-based.
No nā huahana i hoʻopaʻa inoa ʻia, ʻelima i loaʻa nā mea hana i hiki mua i Brazil, ʻekolu i loaʻa nā mea hana o ke kumu olaola hiki ke hoʻohana ʻia i ka mahiʻai organik a ʻelua i loaʻa nā mea hana o ke kumu kemika.
ʻEkolu mau huahana olaola hou (ʻO Neoseiulus barkeri, S. chinensis, a me N. montane) ua hoʻopaʻa inoa ʻia ma lalo o ka Reference Specification (RE) a hiki ke hoʻohana ʻia i kekahi ʻōnaehana mea kanu.
ʻO Neoseiulus barkeri ka huahana mua i hoʻopaʻa inoa ʻia ma Brazil no ka kaohi ʻana iā Raoiella indica, kahi mea ʻino nui o nā kumu niu. Hiki ke ʻōlelo ʻia ka huahana like ma muli o ka hoʻopaʻa inoa ER 45 no ka kaohi ʻana i nā mite keʻokeʻo.
Ua wehewehe ʻo Bruno Breitenbach, ka luna hoʻonohonoho nui o nā pesticides a me nā huahana pili: "ʻOiai he mau huahana kemika kā mākou e kāohi ai i nā ʻuku keʻokeʻo e koho ai, ʻo ia ka huahana olaola mua e kāohi i kēia pest."
ʻO ka wasp parasitic Hua Glazed Wasp ka huahana olaola mua i hoʻokumu ʻia ma ka hoʻopaʻa inoa ER 44. Ma mua o kēlā, hoʻokahi wale nō kemika a nā mea kanu i hiki ke hoʻohana ʻia e kāohi i ka Liriomyza sativae (Liriomyza sativae).
Ma muli o nā Rula Kuhikuhi Helu 46, ua ʻōlelo ʻia ka huahana kaohi olaola i hoʻopaʻa inoa ʻia ʻo Neoseiia mauna mites no ka kaohi ʻana o Tetranychus urticae (Tetranychus urticae). ʻOiai aia kekahi mau huahana olaola ʻē aʻe e hiki ke kaohi i kēia mea ʻino, ʻo kēia huahana kahi koho ʻē aʻe i emi iki ka hopena.
ʻO kahi mea hana kemika i hoʻopaʻa inoa hou ʻiacyclobromoximamideno ke kāohi ʻana i nā anuhe Helicoverpa armigera i nā mea kanu pulupulu, kulina a me ka soybean. Hoʻohana ʻia ka huahana e kāohi iā Leucoptera coffeella i nā mea kanu kofe a me Neoleucinodes elegantalis a me Tuta Absolute i nā mea kanu tōmato.
ʻO kekahi mea hana kemika hou i hoʻopaʻa inoa ʻia ʻo ia ka fungicideʻisofetamid, hoʻohana ʻia e kāohi iā Sclerotinia sclerotiorum i nā mea kanu soybean, bean, ʻuala, tōmato a me ka letus. Manaʻo ʻia hoʻi ka huahana no ke kāohi ʻana iā Botrytis cinerea i nā ʻAkaʻakai a me nā hua waina a me Venturia inaequalis i nā mea kanu ʻāpala.
Hoʻohana nā huahana ʻē aʻe i nā mea hana i hoʻopaʻa inoa ʻia ma Kina. He mea nui loa ke kau inoa ʻana o nā pesticides generic e hōʻemi i ka nui o ka mākeke a hoʻolaha i ka hoʻokūkū, kahi e lawe mai ai i nā manawa kūpono kālepa kūpono a me nā kumukūʻai hana e hoʻohaʻahaʻa i ka mahiʻai Brazil.
Ua kālailai ʻia a ʻāpono ʻia nā huahana i hoʻopaʻa inoa ʻia e nā keʻena kuleana no ke olakino, ke kaiapuni a me ka mahiʻai e like me nā kūlana ʻepekema a me nā hana maikaʻi loa o ka honua.
