1. I-Acetamiprid

Ulwazi Oluyisisekelo:

I-Acetamiprid isibulala-zinambuzane esisha esinobubanzi obubanzi esinomsebenzi othile we-acaricidal, osebenza njengesibulala-zinambuzane esihlelekile enhlabathini namahlamvu.Isetshenziswa kakhulu ekulawuleni irayisi, ikakhulukazi imifino, izihlahla zezithelo, ama-aphid etiye, ama-planthoppers, ama-thrips, nezinye izinambuzane ze-lepidopteran.

Indlela yohlelo lokusebenza:

I-50-100mg / L yokuhlushwa, ingakwazi ukulawula ngempumelelo i-aphid kakotini, i-rapeseed meal, i-peach heartworm encane, njll., ukugxila kwe-500mg / L kungasetshenziswa ukulawula inundu elikhanyayo, inundu elolintshi kanye ne-pear heartworm encane, futhi ingabulala amaqanda.

I-acetamiprid isetshenziswa kakhulu ukulawula izinambuzane ngokufafaza, futhi inani elithile lokusetshenziswa noma inani lomuthi liyahlukahluka kuye ngokuqukethwe kokulungiswa.Ezihlahleni zezithelo nasezitshalweni ezineziqu eziphezulu, izikhathi ezi-3% kuya kwezi-2,000 zamalungiselelo zivame ukusetshenziswa, noma u-5% wamalungiselelo izikhathi ezingu-2,500 kuya kwezingu-3,000, noma u-10% wamalungiselelo yizikhathi ezingu-5,000 kuya kwezingu-6,000, noma u-20%.Ukulungiswa kwe-10000 ~ 12000 izikhathi eziwuketshezi.Noma amanzi angu-40% ama-granules ahlakazekayo 20 000 ~ 25,000 izikhathi eziwuketshezi, noma 50% amanzi ama-granules ahlakazekayo 25000 ~ 30,000 izikhathi eziwuketshezi, noma ama-70% amanzi ahlakazekayo izikhathi ezingu-35 000 ~ 40 000 izikhathi zoketshezi, ngokulinganayo fafaza;emafutheni okusanhlamvu nasemafutheni kakotini Ezitshalweni ezincane njengemifino, ngokuvamile amagremu angu-1.5 kuya ku-2 esithako esisebenzayo asetshenziswa ngamamitha-skwele angama-667, futhi amalitha angama-30 kuya kwangu-60 amanzi ayafafazwa.Ukufafaza okufanayo nokucabangelayo kungathuthukisa umphumela wokulawula womuthi.

Inhloso eyinhloko:

1. Izibulala-zinambuzane ezine-nicotine ezine-chlorine.Umuthi unezici ze-wide insecticidal spectrum, umsebenzi ophezulu, umthamo omncane, umphumela ohlala isikhathi eside kanye nomphumela osheshayo, futhi unemisebenzi yokuthintana nobuthi besisu, futhi unomsebenzi omuhle kakhulu wesistimu.I-Hemiptera (Izintwala, izibungu zesicabucabu, izimpukane, izibungu, izinambuzane zesikali, njll.), I-Lepidoptera (Plutella xylostella, L. moth, P. sylvestris, P. sylvestris), iColeoptera (Echinochloa, Corydalis) Kanye nenani lezinambuzane ezilwa nezimpiko (thuma) ziyasebenza.Njengoba indlela yokusebenza ye-acetamiprid ihlukile kuleyo yezibulala-zinambuzane ezisetshenziswa njengamanje, inemiphumela ekhethekile ezinambuzaneni ezimelana ne-organophosphorus, carbamates kanye ne-pyrethroids.

2. Isebenza kahle ezinambuzaneni ze-Hemiptera ne-Lepidoptera.

3. Iwuchungechunge olufanayo ne-imidacloprid, kodwa i-spectrum yayo ye-insecticidal ibanzi kune-imidacloprid, futhi inomphumela omuhle wokulawula kuma-aphid kukhukhamba, i-apula, i-citrus nogwayi.Ngenxa yendlela eyingqayizivele yokusebenza kwe-acetamiprid, inomphumela omuhle ezinambuzaneni ezimelana nezibulala-zinambuzane ezifana ne-organophosphorus, carbamate, ne-pyrethroids.

2. Imidacloprid

1. Isingeniso esiyisisekelo

I-Imidacloprid iyi-insecticide esebenza kahle kakhulu ye-nicotine.Ine-spectrum ebanzi, esebenza kahle kakhulu, enobuthi obuncane, izinsalela eziphansi, izinambuzane akulula ukukhiqiza ukumelana, futhi iphephile kubantu, izilwane, izitshalo kanye nezitha zemvelo.Inokuthintana, ushevu wesisu kanye nokumuncwa kwesistimu.Linda imiphumela eminingi.Ngemuva kokuthi izinambuzane zivezwe ku-ejenti, ukuqhutshwa okuvamile kwesimiso sezinzwa esiphakathi kuvinjelwe, okwenza ukukhubazeka kufe.Umkhiqizo unomphumela omuhle osebenza ngokushesha, futhi unomphumela wokulawula okuphezulu ngosuku olungu-1 ngemuva komuthi, futhi isikhathi esisele sifika ezinsukwini ezingama-25.Ukusebenza kahle nezinga lokushisa kuhlotshaniswa kahle, izinga lokushisa liphezulu, futhi umphumela wokubulala izinambuzane muhle.Ikakhulukazi esetshenziswa ukulawula ukuncela mouthpart izinambuzane.

2. Izici zomsebenzi

I-Imidacloprid iyi-insecticide esekelwe ku-nitromethylene futhi isebenza njenge-acetylcholinesterase receptor ye-nicotinic acid.Iphazamisa isimiso sezinzwa sezinzwa zezinambuzane futhi ibangele ukudluliselwa kwesignali yamakhemikhali kuhluleke, ngaphandle kokumelana okuphambene.Isetshenziselwa ukulawula izinambuzane ezincelisayo ze-mouthparts kanye nezinhlobo zazo ezimelana nazo.I-Imidacloprid isizukulwane esisha se-nicotine insecticide ene-spectrum ebanzi, ukusebenza kahle okuphezulu, ubuthi obuphansi, izinsalela eziphansi, izinambuzane akulula ukukhiqiza ukumelana, iphephile kubantu, izilwane, izitshalo nezitha zemvelo, futhi inokuxhumana, ubuthi besisu kanye nokumuncwa kwesistimu. .Imiphumela eminingi ye-pharmacological.Ngemuva kokuthi izinambuzane zivezwe ku-ejenti, ukuqhutshwa okuvamile kwesimiso sezinzwa esiphakathi kuvinjelwe, okwenza ukukhubazeka kufe.Inomphumela omuhle wokusebenza ngokushesha, futhi inomphumela wokulawula okuphezulu ngosuku olulodwa ngemuva komuthi, futhi isikhathi esisele siyizinsuku ezingama-25.Ukusebenza kahle nezinga lokushisa kuhlotshaniswa kahle, izinga lokushisa liphezulu, futhi umphumela wokubulala izinambuzane muhle.Ikakhulukazi esetshenziswa ukulawula ukuncela mouthpart izinambuzane.

3. Isetshenziswa kanjani

Isetshenziselwa ikakhulukazi ukuvimbela nokulawula izinambuzane ezincelisayo zomlomo (ingasetshenziswa ngokuzungezisa izinga lokushisa eliphansi le-acetamiprid - izinga lokushisa eliphansi eline-imidacloprid, izinga lokushisa eliphezulu nge-acetamiprid), ukuvimbela nokulawula okufana ne-aphid, planthoppers, whiteflies, leafhoppers, thrips Iphinde isebenze ngokumelene nezinambuzane ezithile ze-Coleoptera, i-Diptera ne-Lepidoptera, njenge-rice weevil, i-rice negative worm, kanye ne-leaf miner.Kodwa akuphumelelanga ngokumelene nematodes nezicabucabu ezibomvu.Ingasetshenziswa elayisi, ukolweni, ummbila, ukotini, amazambane, imifino, beet, izihlahla zezithelo nezinye izitshalo.Ngenxa yezakhiwo zayo ezinhle kakhulu zesistimu, ifaneleka ngokukhethekile ukusetshenziswa ngokwelashwa kwembewu kanye ne-granulation.Ngokuvamile, isithako esisebenzayo singama-3 ~ 10 amagremu, afuthwe ngamanzi noma imbewu.Isikhathi sokuphepha siyizinsuku ezingama-20.Naka isivikelo lapho usebenzisa umuthi, vimbela ukuthintana nesikhumba kanye nokuhogela impushana nomuthi owuketshezi.Geza izingxenye eziveziwe ngamanzi ngemva kokusetshenziswa.Ungaxubani nezibulala-zinambuzane ezine-alkaline.Akunconywa ukufafaza ngaphansi kokukhanya kwelanga okunamandla ukuze ugweme ukunciphisa ukusebenza kahle.

Lawula izinambuzane ezifana ne-Spiraea japonica, izimbuzane ze-apula, i-aphid yepentshisi, i-pear hibiscus, inundu ye-leaf roller, i-whitefly, ne-leafminer, fafaza ngo-10% imidacloprid 4000-6000 izikhathi, noma fafaza ngo-5% imidacloprid EC 2000-3000 izikhathi ezingu-2000-3000Ukuvimbela nokulawula: Ungakhetha i-Shennong 2.1% yejeli yamaphela.
