1. Te waimehatanga me te tukatuka inenga:
Te whakarite i te waipiro whaea: I whakarewaina te 99% TC ki roto i te iti o te etanoru, te waipiro kawakore rānei (pērā i te 0.1% NaOH), kātahi ka tāpirihia he wai hei whakaranu ki te kukū e hiahiatia ana.
Ngā momo horopeta e whakamahia whānuitia ana:
Rehu rau: tukatukahia hei 0.1-0.5% AS, WP rānei.
Te whakamakuku pakiaka: 0.05-0.1% SL.
2. Te wātea me te auau o te hua:
| Momo Hua | Kukū kua whakamahia | Aratau tono | Auautanga | Wā tino nui |
| Hua me huawhenua (tōmato/rōpere) | 50-100 ppm | Rehu rau | 7-10 rā i ngā wā wehe, 2-3 ngā wā | Wāhanga rerekētanga o te puku putiputi/7 ngā rā i mua i te raruraru |
| Mara (witi/raihi) | 20-50 ppm | Te whakamakuku pakiaka | 1 wā | Wāhanga whakatō/whakatūpato wawe i mua i te ngaru makariri |
| Ngā rākau hua (āporo/ārani) | 100-200 ppm | Pania peka | 1 wā | Te tiaki i muri i te kotinga, te whakatika rānei i ngā whara o te hukapapa |
3. Te tapu me te whakaranu:
Āta karohia te whakaranu ki ngā mea parahi (pērā i te ranunga Bordeaux) me ngā patu pepeke waikawa kaha rānei, ka tere pea te taupatupatu.
Monokia i raro i te pāmahana teitei (> 35℃) te mārama kaha rānei, kia kore ai e wera te mata.
