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

  I-Abamectin,i-beta-cypermethrin, futhii-emamectinyizibulala-zinambuzane ezisetshenziswa kakhulu ekulimeni kwethu, kodwa ingabe uyaziqonda ngempela izakhiwo zazo zangempela?

1,I-Abamectin

I-Abamectin iyisibulala-zinambuzane esidala. Sesibe semakethe iminyaka engaphezu kwengu-30. Kungani isachuma namanje?

1. Isimiso sokubulala izinambuzane:

I-Abamectin inamandla okungena kalula futhi idlala indima yokubulala okuthintana nayo kanye nokubulala izinambuzane esiswini. Uma sifafaza izitshalo, izibulala-zinambuzane zizongena ngokushesha ku-mesophyll yesitshalo, bese zakha amasaka anobuthi. Izinambuzane zizoba nokusabela kobuthi lapho zimunca amaqabunga noma zihlangana ne-abamectin ngesikhathi semisebenzi, futhi ngeke zife ngokushesha ngemva kokufakwa ubuthi. , kuzoba nokukhubazeka, ukwehla kokuhamba, ukungakwazi ukudla, futhi ngokuvamile ziyafa zingakapheli izinsuku ezimbili. I-Abamectin ayinawo umphumela wokubulala i-ovial.

2. Ukulawulwa kwezinambuzane okuyinhloko:

Ukusetshenziswa kwe-abamectin ezithelweni nasemifino: kungabulala izimbuzane, izicabucabu ezibomvu, izicabucabu ezigqwalile, izimbuzane zesicabucabu, izimbuzane zenyongo, ama-leaf rollers, ama-diploid borers, i-diamondback moth, i-cotton bollworm, i-green worm, i-beet armyworm, ama-aphid, ama-leaf miners, ama-Psyllids nezinye izinambuzane kunomphumela omuhle kakhulu. Njengamanje, isetshenziselwa kakhulu ilayisi, izihlahla zezithelo, imifino, amakinati, ukotini nezinye izitshalo.

2、I-Beta-cypermethrin

1. Isimiso sokubulala izinambuzane:

Izibulala-zinambuzane ezingezona ezesistimu, kodwa izibulala-zinambuzane ezinemiphumela yobuthi bokuthintana kanye nesisu, zibhubhisa ukusebenza kwesimiso sezinzwa sezinambuzane ngokusebenzisana neziteshi ze-sodium.

2. Ukulawulwa kwezinambuzane okuyinhloko:

I-Beta-cypermethrin iyisibulala-zinambuzane esibanzi esinomphumela omkhulu wokubulala izinambuzane ezinhlotsheni eziningi zezinambuzane. Kukhona: izibungu zikagwayi, izibungu zikakotini, izibungu ezibomvu, ama-aphid, ama-leafminers, amabhungane, izimbungulu ezinuka kabi, ama-psyllid, izilwane ezidla inyama, ama-leaf rollers, izibungu, nezinye izinambuzane eziningi zinemiphumela emihle.

3,Usawoti onobukhulu obungu-A:

1. Isimiso sokubulala izinambuzane:

Uma kuqhathaniswa ne-abamectin, i-emamectin inomsebenzi omkhulu wokubulala izinambuzane. I-Acitretin ingathuthukisa umphumela wezinzwa ezifana ne-amino acid kanye ne-γ-aminobutyric acid, ukuze inani elikhulu lama-ion e-chloride lingene emaseli ezinzwa, okubangela ukulahlekelwa umsebenzi wamaseli, kuphazamise ukuhanjiswa kwezinzwa, futhi izibungu ziyeke ukudla ngokushesha lapho zithintana, okuholela ekukhubazekeni okungenakuguqulwa. Ifa zingakapheli izinsuku ezi-4. Isibulala-zinambuzane sihamba kancane kakhulu. Ezitshalweni ezinezinambuzane eziningi, kunconywa ukuthi zisheshiswe futhi zisetshenziswe ndawonye.

2. Ukulawulwa kwezinambuzane okuyinhloko:

Isetshenziswa kabanzi emifinweni, ezihlahleni zezithelo, ekotini nakwezinye izitshalo, futhi inomsebenzi omkhulu kakhulu wokulwa nezibungu, iLepidoptera, iColeoptera kanye nezinambuzane. Inomsebenzi ongenakuqhathaniswa neminye imithi yokubulala izinambuzane, ikakhulukazi i-red-banded leaf roller, i-tobacco budworm, i-tobacco hawkmoth, i-diamondback moth, i-dryland armyworm, i-cotton bollworm, i-potato beetle, i-cabbage meal borer kanye nezinye izinambuzane.

Uma ukhetha imikhiqizo, kufanele wazi okwengeziwe bese ukhetha ngokwesimo sakho, ukuze uthole indlela ephumelela kakhudlwana yokubulala izinambuzane.
