Kua whakatau ahau ki te whakamātau i ngā patu harore ki ngā pīni soya mō te wā tuatahi i tēnei tau. Me pēhea taku mōhio ko tēhea patu harore hei whakamātau, ā, āhea me whakamahi? Me pēhea taku mōhio mēnā he āwhina?
Ko ngā kaitohutohu hua whaimana o Indiana e whakautu ana i tēnei pātai ko Betsy Bower o Ceres Solutions, Lafayette; ko Jamie Bultemeier, tohunga ahuwhenua, A&L Great Lakes Lab, Fort Wayne; me Andy Like, kaiahuwhenua me te CCA, Vincennes.
Bower: Kōwhiria tētahi hua patu harore me ngā momo mahi whakaranu, kei roto i te iti rawa he triazole me te strobiluron. Kei roto hoki i ētahi ko te matū hohe hou SDHI. Kōwhiria tētahi he pai te mahi ki te ira rau frogeye.
E toru ngā wā o te whakatipu pīni soya e kōrerohia ana e te tini o te tangata..He painga, he ngoikoretanga hoki tō ia wā.Me he mea hou ki ahau te whakamahi i te patu harore pīni soya, ka aro atu ahau ki te wāhanga R3, ina tīmata noa te hanga o ngā hua. I tēnei wāhanga, ka kapi pai te nuinga o ngā rau i te tihi o te rākau.
He tino tōmuri te whakamahinga o te R4, engari he tino whai hua pea mēnā he iti te mate i roto i te tau. Mō te kaiwhakamahi tuatahi o te patu harore, ki taku whakaaro he wawe rawa te whakamahinga o te patu harore i te R2, kua tino puāwai.
Ko te huarahi anake hei mōhio mēnā kei te whakapai ake te hua o te harore patu harore ko te tāpiri i tētahi rīpene tirotiro kāore he paninga ki te mara. Kaua e whakamahi i ngā rarangi pito mō tō rīpene tirotiro, ā, kia rite te whānui o te rīpene tirotiro ki te rahi o te pane whakakotahi, o te porowhita whakakotahi rānei.
I te wā e whiriwhiri ana i ngā patu harore, arotahi ki ngā hua e taea ai te whakahaere i ngā mate kua pā ki a koe i ngā tau kua hipa i a koe e tirotiro ana i ō mara i mua atu, me te wā e whakakī ana i te witi. Mena kāore i te wātea aua mōhiohio, rapua he hua whānui e tuku ana i ngā momo mahi maha.
Bultemeier: E whakaatu ana ngā rangahau ko te hokinga mai nui rawa atu o te haumitanga mō te whakamahinga kotahi o te harore patu huakita ka puta mai i te whakamahinga o te R2 mutunga ki te whakamahinga o te R3 tīmatanga. Tīmatahia te tirotiro i ngā mara pīni soya i te iti rawa i ia wiki mai i te pua. Arotahi ki te mate me te pēhanga pepeke me te wāhanga tipu kia pai ai te wā whakamahinga o te harore patu huakita. Ka kitea te R3 ina he pū 3/16-inihi te whānui i runga i tētahi o ngā pūnga e whā o runga. Mena ka puta mai ngā mate pēnei i te harore mā, te ira rau kanohi peke rānei, me rongoā pea koe i mua i te R3. Mena ka puta te maimoatanga i mua i te R3, ka hiahiatia pea he whakamahinga tuarua i muri mai i te wā e whakakī ana i te witi. Mena ka kite koe i ngā aphids pīni soya nui, ngā pepeke haunga, ngā pīni rau pīni, ngā pīni Hapanihi rānei, he pai ake te tāpiri i te patu ngarara ki te whakamahinga.
Kia mahara ki te waiho i tētahi haki kāore anō kia rongoatia kia taea ai te whakataurite i te hua.
Me haere tonu te tirotiro i te mara i muri i te tono, me te arotahi ki ngā rerekētanga o te pēhanga mate i waenga i ngā wāhanga i rongoatia me ngā wāhanga kāore i rongoatia. Kia piki ake ai te hua o ngā harore patu, me whai mate te harore patu kia taea ai e te harore patu te whakahaere. Whakatauritea te hua i waenga i te mea i rongoatia me te mea kāore i rongoatia i roto i ngā wāhi maha o te mara.
Pēnei i: Ko te tikanga, ko te whakamahi i te harore patu i te wāhanga tipu R3 ka puta ai ngā hua pai rawa atu. He uaua te mōhio ki te harore patu pai rawa atu hei whakamahi i mua i te tīmatanga o te mate. I roto i aku wheako, he pai te mahi a ngā harore patu me ngā momo mahi e rua me te whakatauranga teitei ki te ira rau frogeye. Nā te mea ko tō tau tuatahi tēnei me ngā harore patu pīni soya, ka waiho e au ētahi rīpene tirotiro, ētahi mara wehe rānei hei whakatau i te mahi a ngā hua.
