University City, Pennsylvania — He whānuitia te whakatipu i te witi hotoke i ngā pāmu heihei i te rohe o Mid-Atlantic o te Hononga o Amerika mō te whakaputa witi me te kakau witi. Ka whakamahia te witi hei whāngai kararehe, ā, ka whakamahia te kakau witi hei moenga. Te whakamahinga ongā kaiwhakahaere tipuka taea te whakanui ake i te hua witi mā te pehi i te tipu poutū me te whakaiti i te mōrearea o te noho, he āhuatanga e tino whakaiti ana i te hua witi. Heoi, kāore anō kia mārama te pānga o ngā kaiwhakahaere tipu ki te hua me te kounga o te kakau witi. Nō reira, i whakahaerehia e tētahi rōpū rangahau mai i te Whare Wānanga o Pennsylvania State tētahi rangahau hei aromatawai i ngā pānga ote whakakotahi i ngā kaiwhakahaere tipume ngā tere tono hauota rerekē. I whakahaerehia te rangahau i roto i ngā whakamātautau mara witi hotoke i te Russell E. Larson Agricultural Research Center i te Pennsylvania State University.
"Kāore ngā kaipāmu e hiahia kia nui rawa te tupu o te witi, kia takoto kau ai, ka kino ai te witi, nō reira he maha ngā kaipāmu kua roa e whakamahi ana i ngā kaiwhakahaere tipu tipu," te kī a Daniela Carrijo, he ahorangi tuarua mō te whakaputa witi me te tohunga toronga i te Kāreti o ngā Pūtaiao Ahuwhenua i te Whare Wānanga o Pennsylvania State. "E mōhio ana mātou ka taea e ngā kaiwhakahaere tipu tipu te whakaiti i te mōrearea o te takoto kau me te whakanui ake i te hua o te witi, engari e hiahia ana ngā kaipāmu me ētahi kaipupuri pānga ki te mōhio ki tōna pānga ki te hua me te kounga o te kakau witi. He kaupapa tēnei me ngā pānga mahi, ā, i whakamatauria e mātou tētahi hua e whakamahia whānuitia ana ko te tricyclazole ethyl ester hei whakatau i tōna pānga ki te hua me te kounga o te kakau witi, he mea nui hoki mō ngā pāmu hua whakaranu."
Neke atu i te rua tau te roa, i whakamātauhia e ngā kairangahau ngā huinga e iwa o ngā tono tongi hauota e toru me ngā maimoatanga tricyclazole ethyl ester e toru. I kitea e rātou i whakaitihia e te tricyclazole ethyl ester te teitei o te tipu engari kāore i whakanui ake i te matotoru o te kakau. E rua ngā maimoatanga tricyclazole ethyl ester i whakaitihia te hua kakau mā te 8%, i te mea kotahi te maimoatanga i whakaitihia te hua kakau mā te 5%, ahakoa kāore tēnei rerekētanga i te tino hiranga. I kitea anō e rātou kāore te tricyclazole ethyl ester i whakarerekē i te kounga kakau, i te mimiti wai rānei—ko te tikanga kāore i pā ki te kaha o te kakau ki te pupuri wai, nō reira ka taea tonu te whakamahi i te kakau hei moenga kararehe. I kōrero ngā kairangahau kāore i kitea he wāhi noho i roto i tētahi o ngā māra whakamātautau, ā, ko te whakanui ake i te tono tongi hauota i whakapai ake i te ihirangi pūmua witi.
"He rerekē ā mātou hua—i kitea e mātou ka whakaitihia pea e te tricyclazole ethyl ester te hua o te kakau witi, engari kāore e pā ki te kounga o te kakau witi, ki te hua rānei o te witi," te kī a Carrijo. "Me paunatia e ngā kaipāmu e whakamahi ana i te tricyclazole ethyl ester ngā painga me ngā huakore: ka āwhina pea ki te whakaiti i te noho (mēnā he raruraru tēnei), engari ka whakaitihia pea te hua o te kakau witi. He mea nui rawa tēnei tauwhitiwhiti mēnā he hua pāmu nui te kakau witi, ā, e whakamahia ana hei moenga."

He hoa rangahau paerua ia i tēnei wā i te Whare Wānanga o Wisconsin-Madison. I whai wāhi atu hoki a Ronald Hoover, te kaiwhakahaere kaupapa matua hono i te Tari Pūtaiao Tipu, ki te rangahau.
I tautokona te rangahau e Syngenta me te Whare Wānanga Kai me te Ahuwhenua o te Tari Ahuwhenua o Amerika.
