Ngaba ngokwenene usebenzisa i-abamectin, i-beta-cypermethrin, kunye ne-emamectin ngokuchanekileyo?

  I-Abamectin,i-beta-cypermethrinkunyei-emamectinzezona zinambuzane zisetyenziswa kakhulu ekulimeni kwethu, kodwa ngaba uyaziqonda ngokwenene iimpawu zazo zokwenyani?

1,I-Abamectin

I-Abamectin sisibulali-zinambuzane esidala. Ibisoloko ithengiswa kangangeminyaka engaphezu kwama-30. Kutheni isaphumelela ngoku?

1. Umgaqo wokubulala izinambuzane:

I-Abamectin inamandla okungena kwaye ikakhulu idlala indima yokubulala ngokudibana kunye nokubulala izinambuzane esiswini. Xa sitshiza izityalo, izibulali-zinambuzane ziya kungena ngokukhawuleza kwi-mesophyll yesityalo, emva koko zenze iingxowa zetyhefu. Izinambuzane ziya kuba neempembelelo zetyhefu xa zifunxa amagqabi okanye zidibana ne-abamectin ngexesha lomsebenzi, kwaye aziyi kufa kwangoko emva kokuba zityhefwe. , kuya kubakho ukukhubazeka, ukuncipha kokuhamba, ukungakwazi ukutya, kwaye zihlala zifa kwiintsuku ezi-2. I-Abamectin ayinayo impembelelo yokubulala i-ovial.

2. Ulawulo oluphambili lwezinambuzane:

Ukusetyenziswa kwe-abamectin kwiziqhamo nemifuno: ingabulala iingcongconi, izigcawu ezibomvu, izigcawu ezirhabaxa, iingcongconi ze-spider, iingcongconi ze-gall, i-leaf rollers, i-diploid borers, i-diamondback moth, i-cotton bollworm, i-green worm, i-beet armyworm, i-aphids, i-leaf miners, i-Psyllids kunye nezinye izinambuzane zinefuthe elihle kakhulu. Okwangoku, isetyenziselwa kakhulu irayisi, imithi yeziqhamo, imifuno, amandongomane, i-cotton kunye nezinye izityalo.

2、I-Beta-cypermethrin

1. Umgaqo wokubulala izinambuzane:

Izibulali-zinambuzane ezingezizo ezenkqubo, kodwa izibulali-zinambuzane ezinemiphumo yokutyhefa isisu kunye nokudibana, zitshabalalisa umsebenzi wenkqubo yemithambo-luvo yezinambuzane ngokusebenzisana nemijelo yesodium.

2. Ulawulo oluphambili lwezinambuzane:

I-Beta-cypermethrin sisibulali-zinambuzane esibanzi esinokubulala izinambuzane ezininzi kwiintlobo ngeentlobo zezinambuzane. Kukho: iincukuthu zecuba, ii-cotton bollworms, ii-red bollworms, ii-aphids, ii-leafminers, ii-beetles, ii-stink bugs, ii-psyllids, ii-carnivores, ii-leaf rollers, ii-caterpillars, kunye nezinye izinambuzane ezininzi zinemiphumo emihle.

3,Ityuwa enobukhulu obungu-A:

1. Umgaqo wokubulala izinambuzane:

Xa kuthelekiswa ne-abamectin, i-emamectin inomsebenzi ophezulu wokubulala izinambuzane. I-Acitretin inokunyusa impembelelo yemithambo-luvo efana ne-amino acid kunye ne-γ-aminobutyric acid, ukuze inani elikhulu le-chloride ions lingene kwiiseli zemithambo-luvo, okubangela ukulahleka komsebenzi weseli, ukuphazamisa ukuhanjiswa kwemithambo-luvo, kwaye iimbungu ziyeke ukutya ngoko nangoko xa zidibana, nto leyo ebangela ukukhubazeka okungenakuguqulwa. Ife zingadlulanga iintsuku ezi-4. Isibulali-zinambuzane sicotha kakhulu. Kwizityalo ezinezinambuzane ezininzi, kucetyiswa ukuba sikhawulezise kwaye sizisebenzise kunye.

2. Ulawulo oluphambili lwezinambuzane:

Isetyenziswa kakhulu kwimifuno, imithi yeziqhamo, umqhaphu kunye nezinye izityalo, kwaye inomsebenzi ophezulu wokulwa neencukuthu, iLepidoptera, iColeoptera kunye nezinambuzane. Inomsebenzi ongenakuthelekiswa neminye imithi yokubulala izinambuzane, ingakumbi kwi-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 kunye nezinye izinambuzane.

Xa ukhetha iimveliso, kufuneka wazi okungakumbi uze ukhethe ngokwemeko yakho, ukuze ufumane indlela ephumelelayo yokubulala izinambuzane.
