Topramezone: He Otinga Matū Ahuwhenua me te Ahumahi Matua
Ngā Āpure Tono Matua
I roto i te umanga ahuwhenua, ko te topramezone te tūāpapa o te whakahaere taru hou. He kaha tana mahi hei aukati i te whākōkī 4-hydroxyphenylpyruvate dioxygenase (HPPD) i roto i ngā tipu. Mā te aukati i tēnei whākōkī matua, ka whakararuraru i te ara hanga carotenoid i roto i ngā taru, ka puta te mā o ō rātou rau, ka whakaroa te tipu, ā, i te mutunga, ka mate.

Mō ngā hua rarangi pērā i te kānga, he tino pai te whiriwhiri a te topramezone, ka taea ai e ia te aro ki ngā taru me te whakaiti i te kino ki te hua. Ka taea te whakamahi i mua i te putanga mai, ka hanga he ārai ārai i roto i te oneone hei aukati i te pihinga o te taru, i muri rānei i te putanga mai, ka whawhai tika ki ngā taru e tipu haere ana me te whakaiti i te whakataetae mō ngā rauemi, ā, ka tino whakanui ake i ngā hua me te kounga o te hua.
I roto i te umanga hanga matū, he mea nui te topramezone hei takawaenga. Nā tōna hanganga matū ahurei ka taea e ia te whai wāhi ki ngā tauhohenga maha hei whakaputa i ētahi atu matū whai hua. Hei tauira, ka taea te hanga i ngā hua o te topramezone hei hanga i ngā ngota uaua ake me ngā āhuatanga patu otaota whakarei ake, i ētahi atu mahi motuhake rānei. Tērā pea ka kitea he tono mō ēnei matū kua hangaia ehara i te mea i roto i te rāngai matū ahuwhenua anake engari i roto hoki i ngā mara e pā ana pērā i te rangahau me te whakawhanake i ngā hua tiaki tipu o te whakatupuranga hou.

Mā te pehi i te tipu o te taru i roto i ēnei wāhi, ka āwhina i te pupuri i te pono o ngā hanganga, ka whakaiti i ngā tūponotanga haumaru e pā ana ki ngā tipu kua nui rawa, ā, ka whakaiti i te hiahia mō te tango taru ā-ringa, ā-mīhini rānei i ngā wā katoa, ka penapena i te wā me ngā utu mahi.
Heoi, ahakoa he maha ngā painga o te topramezone, me āta whakahaere. Me rongoa ki te wāhi hauhautanga, maroke, kia matara atu i te rā tika me ngā matū kāore e hototahi. I te wā e whakamahia ana te topramezone, me whai ngā kaiwhakamahi i ngā tikanga haumaru tino pakari, tae atu ki te mau i ngā kākahu tiaki tika, ngā karapu, me ngā mōhiti kanohi, nā te mea ka pāngia te kiri me ngā kanohi e te mamae. Hei tāpiri, me whai i ngā tikanga tika mō te whakakore i ngā hua kāore anō kia whakamahia, ngā rauemi tākai rānei, hei ārai i te poke o te taiao.
