Ingabe ngempela usebenzisa i-abamectin, i-beta-cypermethrin, ne-emamectin ngendlela efanele?

  Abamectin,I-beta-cypermetrin, futhiemamectinziyizibulala-zinambuzane ezisetshenziswa kakhulu ekulimeni kwethu, kodwa ingabe uyaziqonda ngempela izakhiwo zazo zangempela?

1,Abamectin

I-Abamectin isibulala-zinambuzane esidala. Sekuyiminyaka engaphezu kwengu-30 isemakethe. Kungani lisachuma manje?

1. Umgomo wokubulala izinambuzane:

I-Abamectin inokungeneka okuqinile futhi idlala ikakhulukazi indima yokubulala ukuthintana nokubulawa kwezinambuzane esiswini. Lapho sifafaza izitshalo, izibulala-zinambuzane zizongena ngokushesha esitshalweni se-mesophyll, bese zakha amasaka anobuthi. Izinambuzane ziyoba nokusabela kobuthi lapho zimunca amaqabunga noma zihlangana ne-abamectin phakathi nemisebenzi, futhi ngeke zife ngokushesha ngemva kokudliswa ushevu. , kuzoba nokukhubazeka, ukwehla kokuhamba, ukungakwazi ukudla, futhi ngokuvamile kufa phakathi kwezinsuku ezingu-2. I-Abamectin ayinawo umthelela we-ovicidal.

2. Ukulawula izinambuzane okuyinhloko:

Ukusetshenziswa kwe-abamectin ezithelweni nemifino: ingabulala izibungu, izicabucabu ezibomvu, izicabucabu, izibungu zesicabucabu, izibungu zenyongo, ama-leaf roller, ama-diploid borer, inundu ye-diamondback, i-cotton bollworm, i-green worm, i-beet armyworm, ama-aphid, abavukuzi bamaqabunga, ama-Psyllids nezinye izinambuzane zinomphumela omuhle kakhulu. Njengamanje, isetshenziselwa ikakhulukazi irayisi, izihlahla zezithelo, imifino, amantongomane, ukotini nezinye izitshalo.

2,I-Beta-cypermetrin

1. Umgomo wokubulala izinambuzane:

Ama-insecticide angewona ama-systemic, kodwa ama-insecticide anemiphumela yokuxhumana kanye nesisu esiswini, abhubhisa umsebenzi wesimiso sezinzwa zezinambuzane ngokusebenzisana neziteshi ze-sodium.

2. Ukulawula izinambuzane okuyinhloko:

I-Beta-cypermethrin iyisibulala-zinambuzane esine-spectrum esiphezulu esibulala izinambuzane ngokumelene nezinhlobo eziningi zezinambuzane. Kukhona: izibungu zikagwayi, izikelemu zikakotini, izikelemu ezibomvu, izintwala, abavukuzi bamaqabunga, amabhungane, izimbungulu ezinukayo, ama-psyllids, izilwane ezidla inyama, ama-leaf roller, amacimbi nezinye izinambuzane eziningi zinemiphumela emihle.

3,Usawoti we-A-dimensional:

1. Umgomo wokubulala izinambuzane:

Uma kuqhathaniswa ne-abamectin, i-emamectin inomsebenzi wokubulala izinambuzane ophezulu. I-Acitretin ingathuthukisa umphumela wezinzwa ezifana ne-amino acid ne-γ-aminobutyric acid, ukuze inani elikhulu lama-ion e-chloride lingene kumangqamuzana ezinzwa, okubangela ukulahlekelwa ukusebenza kwamangqamuzana, kuphazamise ukuhamba kwezinzwa, futhi izibungu ziyeke ukudla ngokushesha lapho zithintana, okuholela ekukhubazekeni okungenakulungiseka. Ushone phakathi kwezinsuku ezi-4. I-insecticide ihamba kancane kakhulu. Ezitshalweni ezinenani elikhulu lezinambuzane, kunconywa ukuthi kusheshiswe futhi kusetshenziswe ndawonye.

2. Ukulawula izinambuzane okuyinhloko:

Isetshenziswa kabanzi emifino, izihlahla zezithelo, ukotini nezinye izitshalo, futhi inomsebenzi ophakeme kakhulu wokulwa nezibungu, iLepidoptera, iColeoptera nezinambuzane. Inomsebenzi ongenakuqhathaniswa wezinye izibulala-zinambuzane, ikakhulukazi i-red-banded leaf roller, i-gwayi budworm, i-tobacco hawkmoth, inundu ye-diamondback, i-dryland armyworm, i-cotton bollworm, ibhungane lamazambane, i-cabbage meal borer nezinye izinambuzane.

Lapho ukhetha imikhiqizo, kufanele wazi okwengeziwe bese ukhetha ngokuya ngesimo sakho, ukuze uzuze indlela ephumelelayo yokubulala izinambuzane.
