Ko te matū hohe koAbamectin, he paitini puku, he pānga whakamate pā ki ngā mite me ngā pepeke. Mā te rehu ki te mata o te rau ka tere te pirau me te memeha, ā, ko ngā matū hohe e uru ana ki roto i te Parenchyma o te tipu ka noho tonu ki roto i te kiko mō te wā roa, ā, ka whai pānga kawe hiko, ka roa te pānga toenga ki ngā mite kino me ngā pepeke e kai ana i roto i te kiko o te tipu.

Ahakoa he pānga whakamate tika ki ngā hoariri tūturu kaipahua me ngā pirinoa, he iti te kino ki ngā pepeke whai hua nā te iti o te toenga i runga i te mata o te tipu, ā, he mārama te pānga ki ngā nematode pona pakiaka.
