Ukusetshenziswa
Abamectinisetshenziselwa kakhulu ukulawula izinambuzane ezihlukahlukene zezolimo njengezihlahla zezithelo, imifino nezimbali. Njengebhu elincane leklabishi, impukane enamabala, izimbuzane, izintwala, amathrips, i-rapeseed, i-cotton bollworm, i-pear yellow psyllid, inundu kagwayi, inundu ye-soya nokunye. Ngaphezu kwalokho, i-abamectin ibuye isetshenziswe ngokuvamile ekwelapheni izinambuzane ezihlukahlukene zangaphakathi nangaphandle ezingulubeni, amahhashi, izinkomo, izimvu, izinja nezinye izilwane, njengezibungu, amaphaphu, izimpukane zesisu sehhashi, izimpukane zesikhumba senkomo, izibungu zesikhumba, izintwala zezinwele, izintwala zegazi, kanye nezifo ezihlukahlukene ze-parasitic zezinhlanzi nezimfanzi.
Indlela yokwenza
I-Abamectin ibulala izinambuzane ikakhulukazi ngenxa yobuthi besisu kanye nesenzo sokuthinta. Uma izinambuzane zithinta noma ziluma umuthi, izithako zaso ezisebenzayo zingangena emzimbeni wesinambuzane, izidladla, izisekelo zezinyawo nezindonga zomzimba nezinye izitho. Lokhu kuzodala ukwanda kwe-gamma-aminobutyric acid (GABA) nokuvulwa kwamashaneli e-glutamate-gated CI, ukuze i-Cl-inflow ikhule, okubangela i-hyperpolarization yekhono lokuphumula kwe-neuronal, okuholela ekutheni amandla esenzo esivamile angakwazi ukukhululwa, ukuze ukukhubazeka kwemizwa, amangqamuzana emisipha kancane kancane alahlekelwe amandla okubamba, futhi ekugcineni aholele ekufeni kwesibungu.
Izici zomsebenzi
I-Abamectin iwuhlobo lwesibulala-zinambuzane (i-macrolide disaccharide) esebenza kahle kakhulu, i-spectrum ebanzi, ukuthintana kanye nemiphumela enobuthi esiswini. Lapho ifafazwa ebusweni beqabunga lesitshalo, izithako zayo ezisebenzayo zingangena emzimbeni wesitshalo futhi ziqhubeke emzimbeni wesitshalo isikhathi esithile, ngakho-ke inokusebenza isikhathi eside. Ngesikhathi esifanayo, i-abamectin nayo inomphumela obuthakathaka we-fumigation. Okubi ukuthi akuyona i-endogenic futhi ayiwabulali amaqanda. Ngemuva kokusetshenziswa, imvamisa ifinyelela umphumela wayo omkhulu phakathi kwezinsuku ezi-2 kuya kwezi-3. Ngokuvamile, isikhathi esisebenzayo sezinambuzane ze-lepidoptera yizinsuku eziyi-10 kuya kweziyi-15, kanti izibungu ziyizinsuku ezingama-30 kuye kwezingama-40. Ingabulala okungenani izinambuzane ezingama-84 ezifana ne-Acariformes, i-Coleoptera, i-hemiptera (eyayiyi-homoptera ngaphambili) ne-Lepidoptera. Ngaphezu kwalokho, indlela yokusebenza ye-abamectin ihlukile kuleyo ye-organophosphorus, carbamate kanye ne-pyrethroid insecticides, ngakho-ke akukho ukumelana nalezi zinambuzane.
Indlela yokusebenzisa
Izinambuzane zezolimo
| Uhlobo | Ukusetshenziswa | izinyathelo zokuzivikela |
| I-Acarus | Uma izibungu zenzeka, gcoba umuthi, sebenzisa ukhilimu ongu-1.8% izikhathi ezingu-3000 ~ 6000 kunoketshezi (noma 3~6mg/kg), fafaza ngokulinganayo | 1. Lapho usebenzisa, kufanele uzivikele, ugqoke izingubo zokuzivikela namagilavu, futhi ugweme ukuhogela umuthi owuketshezi. 2. I-Abamectin ibola kalula kusisombululo se-alkaline, ngakho-ke ayikwazi ukuhlanganiswa nezibulala-zinambuzane ezine-alkaline nezinye izinto. 3. I-Abamectin inobuthi obukhulu ezinyosini, izikelemu zikasilika nezinye izinhlanzi, ngakho-ke kufanele igwenywe ukuthikameza amakoloni ezinyosi ezizungezile, futhi iqhelelane ne-sericulture, insimu yezithelo zikamalibhele, indawo ye-aquaculture kanye nezitshalo eziqhakazayo. 4. Isikhathi esiphephile sezihlahla zamapheya, i-citrus, irayisi yizinsuku ezingu-14, imifino ye-cruciferous nemifino yasendle yizinsuku ezingu-7, futhi ubhontshisi yizinsuku ezingu-3, futhi ingasetshenziswa izikhathi ezingu-2 ngesizini noma ngonyaka. 5. Ukuze ubambezele ukuvela kokumelana, kunconywa ukushintshanisa ukusetshenziswa kwama-agent anezinqubo ezahlukene ze-insecticidal. 6. Abesifazane abakhulelwe nabancelisayo kufanele bakugweme ukuthintana nalo muthi. 7. Izitsha ezisetshenzisiwe kufanele zilahlwe ngendlela efanele futhi zingalahlwa ngokuthanda kwakho. |
| I-Psyllium pear | Lapho ama-nymphs eqala ukuvela, sebenzisa ukhilimu ongu-1.8% izikhathi ezingu-3000 ~ 4000 kunoketshezi (noma 4.5~6mg/kg), fafaza ngokulinganayo. | |
| Isibungu seklabishi, inundu ye-diamondback, isidla sezihlahla zezithelo | Lapho izinambuzane zenzeka, sebenzisa umuthi, usebenzisa ukhilimu ongu-1.8% izikhathi ezingu-1500 ~ 3000 uketshezi (noma 6~12mg/kg), fafaza ngokulinganayo. | |

| Uhlobo | Ukusetshenziswa | izinyathelo zokuzivikela |
| Ihhashi | I-Abamectin powder 0.2 mg/kg isisindo somzimba/isikhathi, ithathwe ngaphakathi | 1. Ukusetshenziswa akuvunyelwe ezinsukwini ezingama-35 ngaphambi kokuhlatshwa kwemfuyo. 2. Izinkomo nezimvu zokuphuza ubisi akufanele zisetshenziswe ngesikhathi sokukhiqiza ubisi. 3. Uma ujova, kungase kube nokuvuvukala kwendawo okuthambile, okungase kunyamalale ngaphandle kokwelashwa. 4. Lapho unikezwa i-in vitro, umuthi kufanele unikezwe futhi ngemuva kwesikhawu sezinsuku eziyi-7 kuye kweziyi-10. 5. Igcine ivaliwe futhi ikude nokukhanya. |
