2、Beta-cypermethrin

1. Nheyo yemushonga wezvipembenene:

Mishonga yezvipembenene isiri yesystemic, asi mishonga yezvipembenene ine migumisiro yekubata uye chepfu mudumbu, inoparadza mashandiro etsinga dzezvipembenene nekubatana nemigero yesodium.

2. Kudzora zvipembenene zvikuru:

Beta-cypermethrin mushonga wezvipembenene une spectrum yakakura uye unoshanda zvakanyanya pakurwisa zvipembenene zvakasiyana-siyana. Kune: makonye efodya, makonye edonje, makonye matsvuku, maaphid, ma leafminers, mabeetles, stink bugs, psyllids, carnivores, leaf rollers, makonye, ​​nezvimwe zvipembenene zvakawanda zvine mhedzisiro yakanaka.

3,Munyu une divi rimwe chete:

1. Nheyo yemushonga wezvipembenene:

Kana ichienzaniswa neabamectin, emamectin ine simba guru rekuuraya zvipembenene. Acitretin inogona kuwedzera simba retsinga dzakadai seamino acid neγ-aminobutyric acid, zvekuti huwandu hwakawanda hwechloride ions hunopinda mumasero etsinga, zvichikonzera kurasikirwa nekushanda kwemasero, zvichikanganisa kufambisa tsinga, uye honye dzinorega kudya pakarepo padzinobatwa, zvichikonzera kuoma mitezo kusingadzoreki. Inofa mukati memazuva mana. Mushonga wezvipembenene unononoka zvakanyanya. Kune zvirimwa zvine zvipembenene zvakawanda, zvinokurudzirwa kuti kukurumidze kuushandisa pamwe chete.

2. Kudzora zvipembenene zvikuru:

Inoshandiswa zvakanyanya mumiriwo, miti yemichero, donje nezvimwe zvirimwa, uye inoshanda zvakanyanya kurwisa mite, Lepidoptera, Coleoptera nezvipembenene. Inoshanda zvisina muganho sezvimwe zvipembenene, kunyanya kune red-banded leaf roller, tobacco budworm, tobacco hawkmoth, diamondback moth, dryland armyworm, cotton bollworm, potato beetle, cabbage meal borer nezvimwe zvipembenene.

Pakusarudza zvigadzirwa, unofanira kuziva zvakawanda wozosarudza zvinoenderana nemamiriro ako ezvinhu, kuitira kuti uwane nzira inoshanda yekuuraya zvipembenene.
