Ikhwalithi ephezulu ye-Spinosad CAS 131929-60-7 nokulethwa okusheshayo

Incazelo Yomkhiqizo

I-Spinosad inobuthi obuphansi, ukusebenza kahle okuphezulu,I-fungicide ye-spectrum ebanzi.Futhi iye yasetshenziswa emhlabeni wonke ukuzeukulawula izinhlobonhlobo zezinambuzane, okuhlanganisa i-Lepidoptera, i-Diptera, i-Thysanoptera, i-Coleoptera, i-Orthoptera ne-Hymenoptera, nezinye eziningi.I-Spinosad nayo ibhekwa njengomkhiqizo wemvelo, ngakho-ke ivunyelwe ukusetshenziswa kwezolimo eziphilayo yizizwe eziningi.

Ukusebenzisa Izindlela

1. Ngemifinoukulawula izinambuzanewe-diamondback moth, sebenzisa u-2.5% omisa i-ejenti izikhathi ezingu-1000-1500 zesisombululo ukuze ufafaze ngokulinganayo esigabeni esiphezulu sezibungu ezincane, noma usebenzise i-ejenti yokumisa engu-2.5% engu-33-50ml kuya ku-20-50kg yesifutho samanzi njalo ngama-667m².

2. Ukuze ulawule izikelemu ze-beet armyworm, fafaza amanzi ngo-2.5% we-suspension agent 50-100ml njalo ku-667 square metres ekuqaleni kwesigaba sezibungu, futhi umphumela omuhle kakhulu ukusihlwa.

3. Ukuze uvimbele futhi ulawule ama-thrips, njalo kuma-square metres angu-667, sebenzisa i-agent engu-2.5% yokumisa u-33-50ml ukufutha amanzi, noma usebenzise i-2.5% yokumisa izikhathi ezingu-1000-1500 zoketshezi ukuze ufafaze ngokulinganayo, ugxile ezicubu ezincane njengezimbali, ezincane. izithelo, amathiphu kanye amahlumela.

Ukunakwa

1. Kungaba ubuthi ezinhlanzini noma kwezinye izinto eziphila emanzini, futhi ukungcoliswa kwemithombo yamanzi namachibi kufanele kugwenywe.

2. Gcina imithi endaweni epholile neyomile.

3. Isikhathi phakathi kokufakwa kokugcina nokuvuna izinsuku eziyi-7.Gwema ukuhlangana nemvula kungakapheli amahora angama-24 ngemuva kokufafaza.

4. Naka ukuvikelwa kokuphepha komuntu siqu.Uma ithela emehlweni, hlambulula ngokushesha ngamanzi amaningi.Uma uthinta isikhumba noma izingubo, geza ngamanzi amaningi noma amanzi anensipho.Uma kuthathwe ngephutha, ungayenzi ukuziphalaza ngokwakho, ungadli lutho noma ubangele ukuhlanza ezigulini ezingaphapheme noma ezinama-spasms.Isiguli kufanele sithunyelwe ngokushesha esibhedlela ukuze sithole ukwelashwa.

Indlela yokwenza

Indlela yokusebenza ye-polycidin inoveli kakhulu futhi iyingqayizivele, ehlukile kuma-macrolides ajwayelekile, futhi isakhiwo sayo samakhemikhali esiyingqayizivele sinquma indlela yayo eyingqayizivele yokubulala izinambuzane.I-Polycidin inokuthintana ngokushesha kanye nobuthi bokungenisa ezinambuzaneni.Inezimpawu ezinobuthi eziyingqayizivele zama-nerve agents.Indlela yayo yokusebenza iwukushukumisa isimiso sezinzwa zezinambuzane, ukwandisa umsebenzi wayo ngokuzenzekelayo, futhi kuholele ekufinyezeni kwemisipha okungasebenzi, ukwehluleka, okuhambisana nokuthuthumela nokukhubazeka.Kwaboniswa ukuthi i-nicotinic acetylcholine receptor (nChR) yasebenza ngokuqhubekayo ukuze kukhishwe i-acetylcholine (Ach) ende.I-Polycidin iphinde isebenze kuma-γ-aminobutyric acid (GAGB) receptors, iguqule ukusebenza kweziteshi ze-chlorine ezigayiwe ze-GABA futhi ithuthukise umsebenzi wayo wokubulala izinambuzane.

Indlela yokunciphisa

Izinsalela zezibulala-zinambuzane endaweni isho “umthwalo omkhulu” wezibulala-zinambuzane imvelo engase ibe nazo, okungukuthi, endaweni ethile nesikhathi esithile, kokubili ukuze kuqinisekiswe ikhwalithi yebhayoloji kanye nesivuno semikhiqizo yezolimo hhayi ukuphula umthetho. izinga lemvelo."Umthwalo omkhulu" ubuye ube inani elilinganiselwe lokukala ukuphepha kwemvelo kwezibulala-zinambuzane, futhi kubuye kube okuguquguqukayo okwehla kancane kancane ngokushintsha kwesikhathi nezimo zemvelo.Uma nje ingedluli lo mkhawulo, isici sokuphepha kwemvelo sezibulala-zinambuzane siyafaneleka.I-Polycidin ishesha ukuwohloka endaweni ezungezile ngokusebenzisa inhlanganisela yezindlela ezihlukahlukene, ikakhulukazi ukuwohloka kwezithombe kanye nokuwohloka kwamagciwane, futhi ekugcineni ibole ibe izingxenye zemvelo ezifana nekhabhoni, i-hydrogen, umoya-mpilo, ne-nitrogen, ngaleyo ndlela ingangcolisi indawo ezungezile.I-photodegradation half-life ye-polycidin enhlabathini yayiyizinsuku ezingu-9–10, leyo yamaqabunga yayiyizinsuku eziyi-1.6–16, futhi eyamanzi yayingaphansi kosuku olulodwa.Yiqiniso, uhhafu wempilo uhlobene nokuqina kokukhanya, lapho kungabikho ukukhanya, uhhafu wempilo ye-multicidin nge-aerobic inhlabathi metabolism yizinsuku ezingu-9 kuya kweziyi-17.Ukwengeza, i-coefficient yokudlulisa inhlabathi ye-polycidin iphakathi K (5 ~ 323), ukuncibilika kwayo emanzini kuphansi kakhulu futhi kungancipha ngokushesha, ngakho-ke ukusebenza kwe-leaching ye-polycidin kuphansi kakhulu, ngakho-ke ingasetshenziswa kuphela ngokunengqondo. futhi iphephile futhi emithonjeni yamanzi engaphansi komhlaba.
