Te Whakamahi i ngā Tikanga

1. Te ārai me te whakahaere i ngā mite me ngā pepeke i roto i ngā rākau hua me ngā rākau tī. I rehuhia ngā mite rau aporo, ngā aphids aporo, ngā pūngāwerewere whero citrus, ngā mite waikura citrus, ngā kutu rakau, me ngā mite hemitarsal tī ki te 20% formamidine emulsifiable concentrate 1000~1500 Chemicalbook solution (100~200 mg/kg). Ko te roa o te oranga he 1-2 marama. E rima ngā rā i muri i te paninga tuatahi o te mite haurua tarsal tī, me pani anō hei patu i ngā mite hou.

2. Te ārai me te whakahaere i ngā mite huawhenua. Ina puāwai te aubergine, te pīni me ngā torongū pūngāwerewere, rehuhia ki te 1000~2000 wā o te 20% kukū emulsifier (kukū whai hua 100~20 pukapuka matū 0mg/kg). I rehuhia ngā pūngāwerewere me ngā pūngāwerewere ware pi ki te 20% kukū emulsifier 2000~3000 wā (67~100mg/kg) i te wā tino nui o ngā nimfa.
