Ngā Kaupapa Taketake o te Tiaki Hua Hou
Ko te tiaki hua o ēnei rā he raupapa rautaki pūtaiao me ngā rautaki mahi hei pupuri i te hauora, te hua, me te haumaru o ngā tipu mai i ngā rauropi whakararuraru tipu (OPT) pērā i ngā pepeke, ngā mate, me ngā taru kino. I tēnei wā o te ahuwhenua tauwhiro, kāore te tiaki hua e rite ana ki te whakamahi i ngā patu pepeke anake, engari he whakakotahi i ngā huarahi maha—koiora, ahurea, miihini, ira, matihiko, me te matū—i roto i te huarahi whakakotahi. Ehara i te mea ko te patu noa i ngā pepeke, engari ko te whakaiti i ngā mate ōhanga, te pupuri i te kounga o te hua, te tiaki i te taiao, me te whakarite i te haumaru o te kai.
1. He aha te hiranga o te tiaki hua o ēnei rā?
Ka piki ake te hiahia kai i te tipu haere o te taupori, engari he iti noa iho ngā whenua ahuwhenua, ā, kei te piki haere ngā pēhanga o te huringa āhuarangi. Ka taea e ngā āhuatanga huarere kore e taea te matapae te whakaoho i te pahūtanga o te taupori o ētahi pepeke, te whakawhānui ake i te horapa o ngā mate urutā, me te whakarerekē i te whanaketanga o ngā taru. I taua wā, ka tere ake te whakaurunga mai o ngā rauropi whakaeke ki ngā rohe hou e te hokohoko me te nekenekehanga o te ao. Ki te kore he tiaki tika, ka taea e ngā whakaekenga pepeke te whakaiti nui i ngā hua o te hua, te whakanui ake i ngā utu whakaputa, me te whakawehi i te pumau o ngā moni whiwhi a ngā kaimahi pāmu.
Ko te tiaki hua o ēnei rā e aro nui ana ki te haumaru. Mā te whakamahi koretake i ngā patu pepeke ka arahi pea ki te ātete, ki ngā toenga kai, ki te kino o ngā hoariri tūturu, ki te parahanga wai me te oneone, me ngā mōrearea hauora mō ngā kaimahi me ngā kaihoko. Nō reira, ko ngā huarahi hou e aro ana ki ngā whakataunga e ahu mai ana i ngā raraunga me ngā mātāpono whakahaere kawenga.
2. Ariā matua: Te Whakahaere Pest Whakauru (IPM)
Ko te kaupapa matua o te tiaki hua hou ko te Whakahaere Pest Whakauru (IPM). Ka whakakotahihia e te IPM ngā tikanga whakahaere maha, ā, ka tīpakohia ngā mahi tino whai hua, haumaru, me te ohanga. Ko ngā mātāpono matua o te IPM ko:
1. Te ārai: te ārai i ngā raruraru kei puta mai i te tuatahi mā roto i ngā tikanga ahuwhenua pai.
2. Aroturuki: te tirotiro i te taupori OPT me ngā āhuatanga o ngā tipu i ia wā.
3. Paepae whakahaere (paepae ōhanga): ka mahia he mahi ina nui ake te mōrearea o te mate ōhanga i te utu o te whakahaere.
4. Te kaupapa matua o ngā tikanga kore-matū: ko ngā tikanga koiora, hangarau, miihini, me te ā-tinana ngā kaupapa matua; ko ngā tikanga matū te kōwhiringa whakamutunga e whakamahia tika ana.
5. Aromatawai me te whakapai ake: aromatawai i ngā hua o ngā mahi me te whakapai ake i te rautaki mō te wā e whai ake nei.
Mā te IPM, ka nui ake te whakaaro nui mō te whakamahinga o ngā patupatu: te tika ki te whāinga, te horopeta tika, te wā tika, me te tikanga tika.
3. Te tautuhi i te OPT me te tautuhi tika
Ko te taahiraa tuatahi ki te tiaki tipu ko te tautuhi tika i ngā pepeke. He maha ngā hapa whakahaere ka puta mai i te hē o te tātaritanga: ka pohehetia ngā tohu o te korenga o ngā matūkai hei mate, ka pohehetia ngā kino o te rangi hei whakaekenga pepeke, te ritenga kē rānei.
– Ngā pepeke kino: ngā pepeke, ngā noke, ngā nematode, me ētahi atu kararehe e kino tika ana ki ngā tipu.
– Ngā mate: i puta mai i te harore, te huakita, te huaketo, te phytoplasmas, ngā pathogens rānei i roto i te oneone.
– Taru: ngā tipu whakararuraru e whakataetae ana mō te wai, te māramatanga, me ngā matūkai.
Ko te tiakitanga o ēnei rā e whakawhirinaki ana ki te whakakotahitanga o te mātakitaki i te mara, te hopu (hei tauira, ngā hopu pheromone), me te tātaritanga taiwhanga (whakamātautau karuārai, te ahurea mate, me te PCR/ELISA mō ngā mate motuhake). Ko te wawe me te tika o te tātaritanga, ko te whai huatanga o te maimoatanga.
4. Te ārai mā te whakatipu hauora (ahurea hangarau)
Ko te huarahi ahurea hangarau te "rārangi tuatahi o te parepare" tino iti te utu, ā, tino pumau hoki. Hei tauira:
– Ngā kākano hauora, whai tiwhikete hoki hei ārai i ngā mate ka puta mai i ngā kākano.
– Te hurihanga hua hei wawahi i te huringa o ētahi pepeke/mate, inā koa ngā huaketo e kawe ana i te oneone.
– Te horoi i te whenua: te horoi i ngā toenga o ngā tipu mate, ngā taru kino, me ngā taputapu ahuwhenua.
– Te whakarerekē i te tawhiti whakatō me te whakapūngao hau hei whakaiti i te makuku e whakaoho ana i te harore.
– Te whakamomona taurite: ko ngā tipu he nui rawa te hauota ka ngawari ake te pāngia e ētahi pepeke; ka taea hoki e te korenga o te pāhare pāporo te whakaiti i te ātete o te kiko.
– Te whakahaere wai: mā te whakamakuku tika ka taea te whakaiti i te ahotea o ngā tipu me te ārai i ētahi mate.
Ko te tikanga, ko ngā tipu e tupu pai ana ka pai ake te "ora" me te ora anō hoki i te pehanga OPT.
5. Te whakahaere koiora: te whakamahi i ngā hoariri tūturu
Ko te tiakitanga o ēnei rā he mea nui ki ngā matū koiora me te tiaki i ngā hoariri tūturu. Kei roto i ngā hoariri tūturu ko ngā kaipahua (hei tauira, ngā pītau kaipahua), ngā parataiao (ngā wāpu parataiao), me ngā pepeke tukumate (hei tauira, ngā harore entomopathogenic).
Ko ngā momo whakahaere koiora:
– Te Tiaki Taiao: te pupuri i te kāinga noho o ngā hoariri tūturu, te whakaiti i ngā patupatu whānui, te whakato i ngā tipu puāwai (ngā tipu putiputi) hei whakarato i te nekita/hae.
– Te whakanui: te tuku i ngā hoariri tūturu ki te mara (hei tauira, ngā pirinoa mō ētahi pepeke).
– Ngā patupatu koiora: ngā hua i ahu mai i ngā moroiti (Bacillus thuringiensis), ngā harore (Beauveria bassiana), ngā tangohanga otaota rānei.
Ko ngā painga o ngā mea koiora he pai ake mō te taiao, ā, he āwhina ki te pehi i te ātete. Ko ngā wero he puhoi ake te pānga, me whai tikanga taiao tika, ā, me aroturukitia kia āta.
6. Mana ā-tinana me te mana ā-mīhini
Kei te whai tikanga tonu ngā tikanga ā-ringa/ā-tinana, inā koa i runga i te tauine iti ki te tauine waenga, ā, mō te mahi tere:
– Te tango ā-ringa, ā-mīhini rānei i ngā taru.
– Ngā mahanga: ngā rama, te kāpia, ngā pheromones rānei hei whakaiti i te taupori o ngā pepeke.
– Ngā arai ā-tinana: kupenga pepeke, papa kirihou, whare ārai rānei.
– Te whakahaere i te pāmahana: te whakatōtika i te oneone (te taupokina o te oneone ki te kirihou mārama) hei pehi i ngā huaketo me ngā purapura taru.
– Te tapatapahi i ngā wāhanga e pāngia ana hei ārai i te horapa o te mate.
Ahakoa te āhua tuku iho, he mea nui tēnei tikanga o ngā pūnaha hou nā te mea he iti noa ngā toenga, ā, he haumaru hoki.
7. Te ātete ki ngā momo rerekētanga me te hangarau ira
He rautaki tiaki tino whai hua ngā momo ātete nā te mea ka mahi i te wā katoa. Ka whakaputahia e ngā whakatipu tipu hou ngā momo e ātete ana ki ngā mate motuhake, e manawanui ana rānei ki ngā pepeke. Haunga te whakatipu tikanga, kei te whakamahi ētahi whenua i te hangarau koiora me te hangarau ira hei whakawhanake i ngā ātete motuhake (hei tauira, ngā ira hei ātete ki ngā huaketo, ki ngā pepeke rānei).
Heoi, ehara i te otinga kotahi te ātete ki ngā momo tipu. Ka taea e ngā pepeke te urutau, nō reira me whakahaere te ātete: te hurihanga momo tipu, te whakamahi i ngā momo tipu me ngā ira ātete rerekē, me te whakatinana tonu i te IPM hei pupuri i te iti o te pēhanga kōwhiringa.
8. Te whakamahi tika i ngā patu pepeke
He taputapu nui tonu ngā patu pepeke, inā koa ka nui te whakaekenga o ngā pepeke, ā, ka nui te ngaronga o ngā hua. Ko te tikanga o te tiakitanga o ēnei rā ko te "tika":
– Tika tonu: whiriwhiria ngā matū hohe e ai ki te OPT me tōna wāhanga ora.
– Te horopeta me te kukū tika: whai i te tapanga me ngā taunakitanga mana.
– I te wā tika: i runga i ngā paepae aroturuki me te whakahaere, kaua ko ngā wātaka anake.
– Tikanga tono tika: te whakatikatika i te taputapu rehu, te nui o te rehu, me te tiaki a te kaiwhakahaere.
– Hurihanga o te aratau mahi: hei ārai i te ātete, kaua e whakamahi tonu i ngā matū hohe me te tikanga mahi kotahi.
Hei tāpiritanga, he mea nui kia aro ki te wā i mua i te kotinga (PHI) me ngā herenga toenga mōrahi (MRL) kia haumaru ai te kotinga mō te kai, kia tutuki ai hoki ngā paerewa mākete.
9. Te ahuwhenua tika me te mamati o te tiaki hua
Ko tētahi o ngā tohu o te "hou" ko te whakamahinga o ngā raraunga me ngā hangarau. Inaianei ka taea e ngā kaiahuwhenua me ngā tohunga ahuwhenua te whakamahi i:
– Ngā pūoko me ngā teihana huarere hei matapae i te mōrearea o te mate (i runga i te haumākū, te pāmahana me te ua).
– Ngā waka rererangi korere mō te mahere i ngā pepeke me ngā tono rehu me te kapinga kua whakaritea.
– Ngā whakaahua amiorangi hei kite wawe i te ahotea o ngā tipu.
– Te tono tuhi mō te hītori whakaeke, te whakamahinga o ngā patu pepeke, me te aromatawai i te wā whakato.
Mā tēnei hangarau, ka tika ake te whakahaere, ka whakaitihia te para whakauru me te pānga ki te taiao.
10. Whakatau: ko te whakaurunga te mea nui
Ko ngā tūāpapa o te tiaki hua hou kei runga i te whakaurunga: te ārai, te aroturuki, te whiriwhiri i ngā tikanga haumaru me te tino whai hua, me te aromatawai tonu. Ko te IPM te anga matua e whakakotahi ana i te ahurea hangarau, koiora, me te hangarau, ngā momo ātete, te hangarau matihiko, me te whakamahinga tupato o ngā patu pepeke. Mā tēnei huarahi, ka taea e te ahuwhenua te whakaputa hua kounga teitei me te pupuri i te hauora o te rauropi, te tiaki i ngā kaimahi, me te whakatutuki i te hiahia o ngā kaihoko mō te kai haumaru.
Hei whakamutunga, ehara te tiaki hua whenua hou i te hua kotahi, i te tikanga kotahi rānei, engari he huarahi whakaaro: te whakahaere i ngā pūnaha ahuwhenua i runga i te mohio, i te pūtaiao, me te kawenga hoki, kia mau tonu ai te oranga mō te wā roa.
