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?

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, izinambuzane zamaqabunga, 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, okubangele ukulahlekelwa ukusebenza kwamangqamuzana, kuphazamise ukuhamba kwezinzwa, futhi izibungu ziyeke ukudla ngokushesha lapho zithintana, okuholela ekulahlekelweni kokusebenza kweseli. ukukhubazeka.Ushone phakathi kwezinsuku ezi-4.I-insecticide ihamba kancane kakhulu.Ezitshalweni ezinenani elikhulu lezinambuzane, kunconywa ukuthi kusheshiswe futhi kusetshenziswe ndawonye.

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