Ese koko ukoresha abamectin, beta-cypermethrin, na emamectin neza?

  Abamectin,beta-cypermethrine, naemamectinni imiti yica udukoko ikoreshwa cyane mu buhinzi bwacu, ariko se koko urabyumva neza imiterere yayo nyayo?

1,Abamectin

Abamectin ni umuti wica udukoko ushaje. Umaze imyaka irenga 30 ku isoko. Kuki ukiri gutera imbere muri iki gihe?

1. Ihame ry'imiti yica udukoko:

Iyo duteye imiti, imiti yica udukoko ihita yinjira mu gice cy’ibimera cya mesophyll, hanyuma igakora udusaho tw’uburozi. Udukoko tuzagira ingaruka z’uburozi iyo tunyoye amababi cyangwa tuyahuye na abamectin mu gihe cy’ibikorwa, kandi ntituzapfa ako kanya nyuma yo gutozwa. , hazabaho ubumuga, kugabanuka kw’uburyo bwo kugenda, kudashobora kurya, kandi akenshi igapfa mu minsi 2. Abamectin nta ngaruka igira ku jisho.

2. Uburyo bw'ingenzi bwo kurwanya udukoko:

Gukoresha abamectin ku mbuto n'imboga: bishobora kwica udukoko, udukoko dutukura, udukoko twa rust, udukoko twa gall, udukoko twa leaf rollers, udukoko twa diploid, diamondback moth, cotton bollworm, green worm, beet armyworm, aphids, leaf mining, Psyllids n'utundi dukoko bigira ingaruka nziza cyane.

2、Beta-cypermethrine

1. Ihame ry'imiti yica udukoko:

Imiti yica udukoko itari iy’umubiri, ahubwo irimo imiti yica udukoko igira ingaruka ku gukoraho no kuvura igifu, yangiza imikorere y’imitsi y’udukoko ikoresheje uburyo bwo gukorana n’imiyoboro ya sodium.

2. Uburyo bw'ingenzi bwo kurwanya udukoko:

Beta-cypermethrin ni umuti wica udukoko mu buryo bwagutse kandi wica udukoko twinshi mu bwoko butandukanye bw’udukoko. Hari: udukoko tw’itabi, udukoko tw’ipamba, udukoko tw’umutuku, udukoko tw’inkoko, udukoko tw’ibimera, udukoko, udukoko duto, udukoko two mu bwoko bwa psyllids, udukoko tw’inkoko, udukoko two mu bwoko bwa leaf roller, udukoko, n’utundi dukoko twinshi tugira ingaruka nziza.

3,Umunyu ufite ingano ya A:

1. Ihame ry'imiti yica udukoko:

Ugereranyije na abamectin, emamectin ifite imikorere yo kwica udukoko cyane. Acitretin ishobora kongera ingaruka z'imitsi nka aside amine na aside γ-aminobutyric, ku buryo ioni nyinshi za chloride zinjira mu turemangingo tw'imitsi, bigatera kubura imikorere y'uturemangingo, bigahungabanya uburyo imitsi ikora, kandi inyo zigahagarika kurya ako kanya iyo zikozeho, bigatuma habaho ubumuga budasubirwaho. Zipfa mu minsi 4. Iyi miti yica udukoko iratinda cyane. Ku bihingwa bifite udukoko twinshi, ni byiza kwihutisha no kubikoresha hamwe.

2. Uburyo bw'ingenzi bwo kurwanya udukoko:

Ikoreshwa cyane mu mboga, ibiti by'imbuto, ipamba n'ibindi bihingwa, kandi ifite imikorere myinshi mu kurwanya udukoko, Lepidoptera, Coleoptera n'udukoko. Ifite imikorere idasanzwe nk'indi miti yica udukoko, cyane cyane ku dukoko twitwa red-banded leaf roller, tobacco budworm, tobacco hawkmoth, diamondback moth, dryland armyworm, cotton bollworm, potato beetle, cabbage meal borer n'utundi dukoko.

Mu guhitamo ibicuruzwa, ugomba kumenya byinshi hanyuma ugahitamo ukurikije uko umeze, kugira ngo ugere ku buryo bwiza bwo kwica udukoko.
