I-Spinosad CAS 131929-60-7 Esezingeni Eliphezulu Nokulethwa Okusheshayo

Incazelo Yomkhiqizo

I-Spinosad iwubuthi obuphansi, ukusebenza kahle okuphezulu,isikhunta esibanziFuthi ibilokhu isetshenziswa emhlabeni wonke ngenxaukulawulwa kwezinambuzane ezahlukahlukene, okuhlanganisa iLepidoptera, iDiptera, iThysanoptera, iColeoptera, i-Orthoptera kanye neHymenoptera, kanye nabanye abaningi. I-Spinosad nayo ibhekwa njengomkhiqizo wemvelo, ngakho-ke ivunyelwe ukusetshenziswa kwezolimo eziphilayo yizizwe eziningi.

Ukusebenzisa Izindlela

1. Ngemifinoukulawulwa kwezinambuzaneye-diamondback moth, sebenzisa i-2.5% sleeping agent izikhathi ezingu-1000-1500 zesisombululo ukuze ufafaze ngokulinganayo esigabeni esiphezulu sezibungu ezincane, noma sebenzisa i-2.5% sleeping agent 33-50ml kuya ku-20-50kg wamanzi spray njalo ngemizuzu engu-667m.².

2. Ukulawula i-beet armyworm, fafaza ngamanzi nge-2.5% suspension agent 50-100ml njalo ngamamitha-skwele angu-667 esigabeni sokuqala sama-larval, futhi umphumela omuhle kakhulu uba kusihlwa.

3. Ukuze uvimbele futhi ulawule ama-thrip, njalo ngamamitha-skwele angu-667, sebenzisa i-2.5% stop agent engu-33-50ml ukuze ufafaze amanzi, noma sebenzisa i-2.5% stop agent izikhathi ezingu-1000-1500 zoketshezi ukuze ufafaze ngokulinganayo, ugxile ezicutshini ezincane njengezimbali, izithelo ezincane, ama-tip kanye namahlumela.

Ukunaka

1. Kungaba yingozi ezinhlanzini noma kwezinye izinto eziphilayo zasemanzini, futhi ukungcola kwemithombo yamanzi namachibi kufanele kugwenywe.

2. Gcina umuthi endaweni epholile neyomile.

3. Isikhathi esiphakathi kokufaka okokugcina kanye nokuvuna yizinsuku eziyi-7. Gwema ukuhlangana nemvula zingakapheli amahora angama-24 ngemuva kokufutha.

4. Naka ukuvikelwa kokuphepha komuntu siqu. Uma kugalela emehlweni, hlanza ngokushesha ngamanzi amaningi. Uma kuthinta isikhumba noma izingubo, geza ngamanzi amaningi noma ngamanzi anensipho. Uma kwenziwa ngephutha, ungazihlanzi wedwa, ungaphakeli lutho noma uhlanze iziguli ezingavukile noma ezinezinhlungu. Isiguli kufanele sithunyelwe esibhedlela ngokushesha ukuze sithole ukwelashwa.

Indlela yesenzo

Indlela esebenza ngayo i-polycidin intsha kakhulu futhi ihlukile, ehlukile kuma-macrolide ajwayelekile, futhi isakhiwo sayo samakhemikhali esiyingqayizivele sinquma indlela yayo ehlukile yokubulala izinambuzane. I-Polycidin inokuthintana okusheshayo nokugwinya ubuthi ezinambuzaneni. Inezimpawu ezinobuthi ezihlukile ze-nerve agents. Indlela esebenza ngayo ukukhuthaza uhlelo lwezinzwa lwezinambuzane, ukwandisa umsebenzi wayo ozenzakalelayo, nokuholela ekuncipheni kwemisipha okungasebenzi, ukwehluleka, okuhambisana nokuthuthumela nokukhubazeka. Kwaboniswa ukuthi i-nicotinic acetylcholine receptor (nChR) yayisebenza njalo ukuze ibangele ukukhululwa kwe-acetylcholine (Ach) isikhathi eside. I-Polycidin iphinde isebenze kuma-receptor e-γ-aminobutyric acid (GAGB), ishintsha umsebenzi weziteshi ze-GABA ezivikelwe yi-chlorine futhi ithuthukise umsebenzi wayo wokubulala izinambuzane.

Indlela yokuwohloka

Insalela yezibulala-zinambuzane emvelweni ibhekisela “kumthwalo omkhulu” wezibulala-zinambuzane ezingaba khona emvelweni, okungukuthi, endaweni ethile kanye nesikhathi esithile, kokubili ukuqinisekisa ikhwalithi yezinto eziphilayo kanye nesivuno semikhiqizo yezolimo hhayi ukuphula ikhwalithi yemvelo. “Umthwalo omkhulu” futhi uyinani elilinganiselwe lokulinganisa ukuphepha kwemvelo kwezibulala-zinambuzane, futhi futhi kuyinguquko encipha kancane kancane ngokushintsha kwesikhathi kanye nezimo zemvelo. Uma nje ingadluli lo mkhawulo, isici sokuphepha kwemvelo sezibulala-zinambuzane siyafaneleka. I-Polycidin yonakala ngokushesha emvelweni ngezindlela ezahlukahlukene ezihlanganisiwe, ikakhulukazi ukubola kwe-photo kanye nokuwohloka kwamagciwane, futhi ekugcineni ibola ibe yizingxenye zemvelo ezifana nekhabhoni, i-hydrogen, i-oxygen, ne-nitrogen, ngaleyo ndlela ingabangela ukungcola emvelweni. Impilo yengxenye ye-polycidin yokubola kwe-photodegradation enhlabathini yayiyizinsuku ezingu-9-10, eyengaphezulu kweqabunga yayiyizinsuku ezingu-1.6-16, kanti eyamanzi yayingaphansi kosuku olulodwa. Yiqiniso, ingxenye yokuphila ihlobene nobukhulu bokukhanya, uma kungekho ukukhanya, ingxenye yokuphila kwe-multicidin ngokusetshenziswa kwe-aerobic soil metabolism izinsuku ezingu-9 kuya kwezingu-17. Ngaphezu kwalokho, i-coefficient yokudlulisa isisindo somhlabathi ye-polycidin ingu-K ophakathi (5~323), ukuncibilika kwayo emanzini kuphansi kakhulu futhi kungonakaliswa ngokushesha, ngakho-ke ukusebenza kwe-leaching ye-polycidin kuphansi kakhulu, ngakho-ke ingasetshenziswa kuphela ngokunengqondo, futhi iphephile nasemithombo yamanzi angaphansi komhlaba.
