Yiziphi izinto ezibalulekile okufanele uzazi nge-Abamectin?

I-AbamectinIsetshenziswa kakhulu ukulawula i-Plutella xylostella, i-Pieris rapae, i-Spodoptera exigua, i-Spodoptera litura, ama-leafminers, ama-leaf rollers, i-Manduca sexta, ama-root-knot nematodes, ama-aphid kanye nezibungu ezinambuzane ezahlukahlukene. Indlela yayo yokusebenza ukukhuthaza ukukhishwa kwe-γ-aminobutyric acid (GABA), evimbela ukuqhutshwa kwemizwa ezinambuzaneni, ekugcineni okuholela ekukhubazekeni kwezinambuzane, ukuyeka ukudla kanye nokufa.

Izinambuzane Ezinokulawula Okuhle Kakhulu Ukusebenza Kahle Kwe-I-Abamectin

1. I-Spectrum Yokulawula Izinambuzane

I-Abamectin ingasetshenziswa ukulawula i-Plutella xylostella, i-Pieris rapae, i-leaf miners, i-Liriomyza spp., i-Spodoptera exigua, i-Spodoptera litura, i-Phyllonorycter ringoniella, i-leafminer moth, i-leaf roller moth, i-Heliothis virescens, i-Manduca sexta, i-root-knot nematodes, ama-aphid nazo zonke izinhlobo zezibungu ezidla izinambuzane (kufaka phakathi i-Hawthorn Spider Mite, i-European Red Mite, i-Two-spotted Spider Mite, i-Citrus Red Mite, i-Rust Mite, i-Pear Psylla, njll.).

2. Indlela Yokwenza

I-Abamectin ihlasela ama-GABAA receptors kuma-neuronal synapses noma kuma-neuromuscular synapses ezinambuzane, iphazamisa ukudluliselwa kwesignali kuma-terminals emizwa yezinambuzane. Ivuselela ama-terminals emizwa ukuze ikhulule i-neurotransmitter inhibitor i-γ-aminobutyric acid (GABA), ivuselela iziteshi ze-ion ze-chloride ezigadwe yi-GABA futhi yandise isikhathi sayo sokuvula. Ukungena okukhulu kwama-ion e-chloride kubangela ukwanda kwe-hyperpolarization yamandla e-membrane yemizwa, okugcina i-membrane yemizwa isesimweni sokuvimbela. Lokhu kuvimbela ukuxhumana kwesignali phakathi kwama-terminals emizwa nemisipha, okuholela ekukhubazekeni, ekuyekeni kokudla kanye nasekufeni kwezinambuzane.

Izindlela Zokusebenzisa i-Abamectin

1. Ukulawula i-diamondback moth (I-Plutella xylostella) kanye ne-cabbageworm engenisiwe (I-Pieris rapae): Futha ingxube ye-2% ye-Abamectin EC exutshwe izikhathi ezingu-1000–1500 + 1% ye-Emamectin Benzoate exutshwe izikhathi ezingu-1000 esigabeni sama-larval amancane.
2. Ukulawula i-apple leafminer, ama-leaf miner moth, izimpukane ze-leafminer, i-American serpentine leafminer kanye ne-whitefly: Isifutho esingu-1.8% se-Abamectin EC esixutshwe izikhathi ezingu-3000–5000 sixutshwe ne-cypermethrin esebenza kahle kakhulu exutshwe izikhathi ezingu-1000 ngesikhathi sokuchamisela kwamaqanda kanye nesikhathi sokuqubuka kwama-larval.
3. Ukulawula i-beet armyworm (I-Spodoptera exigua): Isifutho esingu-1.8% se-Abamectin EC esixutshwe izikhathi eziyi-1000.
4. Ukulawula izimbuzane zesicabucabu, izimbuzane zetiye eziphuzi, izimbuzane zenyongo kanye nezimbuzane ezihlahleni zezithelo, imifino kanye nezitshalo zokusanhlamvu: Futha i-1.8% ye-Abamectin EC exutshwe izikhathi ezingu-4000–6000.
5. Ukulawula isifo se-root-knot nematode yemifino: Faka izimpande emanzini angu-500 mL we-1.8% Abamectin EC exutshwe ngamanzi nge-mu.
6. Ukulawula i-cotton bollworm (I-Helicoverpa armigera): Nciphisa u-60 mL we-1.8% Abamectin EC ngamanzi angu-50–60 kg nge-mu bese ufafaza kahle ngesikhathi sokuchamisela kwamaqanda.
7. Ukulawula i-pear psylla: Futha i-1.8% Abamectin EC exutshwe izikhathi ezingu-6000–8000.
8. Ukuze kulawulwe ama-aphid ezimbali, izinambuzane ezinamabala kanye nama-thrip: Nciphisa u-30–50 mL we-1.8% Abamectin EC ngamanzi nge-mu bese ufafaza.
9. Ukulawula i-rice leaf roller (I-Cnaphalocrocis medinalis): Hlanza u-30–45 mL we-2.2% Abamectin EW ngamanzi nge-mu bese ufutha.
