He aha ngā mea nui e tika ana kia mōhio koe mō Abamectin?

AbamectinKo te nuinga o te wā ka whakamahia hei whakahaere i te Plutella xylostella, Pieris rapae, Spodoptera exigua, Spodoptera litura, ngā kaikeri rau, ngā rau hurihuri, Manduca sexta, ngā nematode pūtake-pūtake, ngā aphids me ngā momo mite pepeke. Ko tana tikanga mahi he whakaoho i te tukunga o te waikawa γ-aminobutyric (GABA), e aukati ana i te kawe io o ngā pepeke, ā, ka mutu ka arahi ki te pararutiki o ngā pepeke, te whakamutu kai me te mate.

Ngā Pests me te Whai Huatanga Tino Pai o te WhakahaereAbamectin

1. Te Āhuatanga Whakahaere Pepeke

Ka taea te whakamahi i te Abamectin hei whakahaere i te Plutella xylostella, Pieris rapae, leaf miners, Liriomyza spp., Spodoptera exigua, Spodoptera litura, Phyllonorycter ringoniella, leafminer moths, leaf roller moths, Heliothis virescens, Manduca sexta, root-knot nematodes, aphids me ngā momo mite pest katoa (tae atu ki te Hawthorn Spider Mite, European Red Mite, Two-spotted Spider Mite, Citrus Red Mite, Rust Mite, Pear Psylla, me ētahi atu).

2. Aratau Mahi

Ka aro atu a Abamectin ki ngā kaiwhakawhiwhi GABAA i ngā hononga io, i ngā hononga uaua rānei o ngā pepeke, ka whakararu i te tuku tohu i ngā pito io o ngā pepeke. Ka whakaoho i ngā pito io ki te tuku i te aukati neurotransmitter γ-aminobutyric acid (GABA), ka whakahohe i ngā hongere ion chloride kua āraihia e te GABA, ā, ka roa ake te wā whakatuwheratanga. Ko te nui o te rerenga mai o ngā ion chloride ka puta te hyperpolarization o te pūmanawa membrane nerve, ka noho tonu te membrane nerve ki te āhua aukati. Ka aukati tēnei i te whakawhitiwhiti tohu i waenga i ngā pito io me ngā uaua, ka hua ake te pararutiki, te whakamutu kai me te mate o ngā pepeke.

3. Hei whakahaere i te noke pīti (Spodoptera exigua): Rehu 1.8% Abamectin EC kia whakaranua kia 1000 ngā wā.
4. Hei whakahaere i ngā moka pungawerewere, ngā moka tī kōwhai, ngā moka au me ngā aphids i runga i ngā rākau hua, huawhenua me ngā hua witi: Rehuhia te 1.8% Abamectin EC kia 4000–6000 ngā wā i whakaranua ai.
5. Hei whakahaere i te mate nematode o te pūtake huawhenua: Tauhiuhia ngā pūtake ki te 500 mL o te 1.8% Abamectin EC kua waimeha ki te wai mō ia mu.
6. Hei whakahaere i te kutukutu miro (Helicoverpa armigera): Whakaranua te 60 mL o te 1.8% Abamectin EC ki te 50–60 kg wai mō ia mu ka rehuhia kia tino pai i te wā tino pao o te hua manu.
7. Hei whakahaere i te pea psylla: Rehuhia te 1.8% Abamectin EC kia 6000–8000 ngā wā i whakaranua ai.
8. Hei whakahaere i ngā aphids putiputi, ngā pepeke unahi me ngā thrips: Whakaranua te 30–50 mL o te 1.8% Abamectin EC ki te wai mō ia mu ka rehu.
9. Hei whakahaere i te takai rau raihi (Cnaphalocrocis medinalis): Whakaranua kia 30–45 mL o te 2.2% Abamectin EW ki te wai mō ia mu ka rehu.
