I-Spinosad CAS 131929-60-7 ekumgangatho ophezulu enokuhanjiswa ngokukhawuleza

Ingcaciso yeMveliso

I-Spinosad ayinobungozi kakhulu, isebenza kakuhle,i-fungicide ye-spectrum ebanziKwaye isetyenzisiwe kwihlabathi liphelaulawulo lweentlobo ngeentlobo zezinambuzane eziyingozi, kuquka iLepidoptera, iDiptera, iThysanoptera, iColeoptera, iOrthoptera kunye neHymenoptera, kunye nezinye ezininzi. I-Spinosad ikwathathwa njengemveliso yendalo, ngoko ke ivunyiwe ukuba isetyenziswe kwezolimo eziphilayo zizizwe ezininzi.

Ukusebenzisa Iindlela

1. Ngemifunoabalawuli berhorhoye-diamondback moth, sebenzisa i-2.5% ye-suspension agent izihlandlo ezili-1000-1500 zesisombululo ukuze utshize ngokulinganayo kwinqanaba eliphezulu lee-larvae ezincinci, okanye sebenzisa i-2.5% ye-suspension agent 33-50ml ukuya kwi-20-50kg yamanzi rhoqo emva kwe-667m.².

2. Ukulawula i-beet armyworm, fafaza ngamanzi nge-2.5% suspension agent 50-100ml rhoqo kwi-667 square metres kwinqanaba lokuqala le-larval, kwaye isiphumo esihle kakhulu sisebusuku.

3. Ukuthintela nokulawula ii-thrips, rhoqo kwi-667 square metres, sebenzisa i-2.5% suspending agent 33-50ml ukutshiza amanzi, okanye sebenzisa i-2.5% suspending agent izihlandlo ezili-1000-1500 zolwelo ukutshiza ngokulinganayo, ugxile kwizicubu ezincinci ezifana neentyatyambo, iziqhamo ezincinci, iincam kunye namahlumela.

Iingqalelo

1. Inokuba yityhefu kwiintlanzi okanye kwezinye izinto eziphilayo zasemanzini, kwaye ungcoliseko lwemithombo yamanzi kunye namachibi kufuneka luphetshwe.

2. Gcina iyeza kwindawo epholileyo neyomileyo.

3. Ixesha eliphakathi kokufaka okokugqibela kunye nokuvuna liintsuku ezisi-7. Kuphephe ukufumana imvula zingadlulanga iiyure ezingama-24 emva kokutshiza.

4. Nika ingqalelo kukhuseleko lomntu. Ukuba ingena emehlweni, hlambulula ngoko nangoko ngamanzi amaninzi. Ukuba idibana nolusu okanye impahla, hlamba ngamanzi amaninzi okanye ngamanzi anesepha. Ukuba yenziwe ngempazamo, musa ukuzihlanza wedwa, musa ukondla nantoni na okanye ukuhlanza izigulane ezingavukiyo okanye ezineentlungu. Isigulana kufuneka sithunyelwe esibhedlele ngoko nangoko ukuze sifumane unyango.

Indlela yokusebenza

Indlela esebenza ngayo i-polycidin intsha kakhulu kwaye yahlukile, nto leyo eyahlukileyo kwi-macrolides ngokubanzi, kwaye ulwakhiwo lwayo olukhethekileyo lweekhemikhali lumisela indlela yayo yokubulala izinambuzane eyahlukileyo. I-Polycidin inobuthi obukhawulezileyo bokudibana nokuginya izinambuzane. Ineempawu ezinobungozi ezikhethekileyo zee-nerve agents. Indlela esebenza ngayo kukuvuselela inkqubo ye-nerve yezinambuzane, ukwandisa umsebenzi wayo ozenzekelayo, kwaye ikhokelele ekucuthekeni kwemisipha okungasebenziyo, ukungaphumeleli, okuhamba nokungcangcazela kunye nokukhubazeka. Kuboniswe ukuba i-nicotinic acetylcholine receptor (nChR) yayisebenza rhoqo ukuze ibangele ukukhululwa kwe-acetylcholine (Ach) ixesha elide. I-Polycidin ikwasebenza kwi-receptors ze-γ-aminobutyric acid (GAGB), itshintsha umsebenzi we-GABA gated chlorine channels kwaye iphucula ngakumbi umsebenzi wayo wokubulala izinambuzane.

Indlela yokuwohloka

Intsalela yezibulali-zinambuzane kwindalo ibhekisa "kumthwalo ophezulu" wezibulali-zinambuzane ezinokuthi ziqulathwe yindalo, oko kukuthi, kwindawo ethile nakwixesha elithile, zombini ukuqinisekisa umgangatho webhayoloji kunye nemveliso yemveliso yezolimo kwaye kungaphuli umgangatho wendalo. "Umthwalo ophezulu" ikwalixabiso elilinganiselweyo lokulinganisa ukhuseleko lwendalo lwezibulali-zinambuzane, kwaye ikwangutshintsho oluyehla kancinci ngokutshintsha kwexesha kunye neemeko zendalo. Logama nje ingadluli kulo mda, into yokhuseleko lwendalo yezibulali-zinambuzane iyafaneleka. I-Polycidin yonakala ngokukhawuleza kwindalo ngokusebenzisa iindlela ezahlukeneyo ezidibeneyo, ikakhulu ukubola kwe-photo kunye nokubola kweentsholongwane, kwaye ekugqibeleni ibola ibe ziinxalenye zendalo ezifana nekhabhoni, i-hydrogen, ioksijini, kunye ne-nitrogen, ngaloo ndlela ingabangela ungcoliseko kwindalo. Ubomi obufutshane be-polycidin kwi-photodegradation emhlabeni yayiziintsuku ezili-9 ukuya kwezili-10, obomphezulu wamagqabi yayiziintsuku ezili-1.6 ukuya kwezili-16, kwaye obo bamanzi babungaphantsi kosuku olunye. Kakade ke, isiqingatha sobomi sinxulumene nobukhali bokukhanya, xa kungekho kukhanya, isiqingatha sobomi be-multicidin yi-aerobic soil metabolism yiintsuku ezili-9 ukuya kwezili-17. Ukongeza, i-coefficient yokudluliselwa kobunzima bomhlaba ye-polycidin yi-K ephakathi (5 ~ 323), ukunyibilika kwayo emanzini kuphantsi kakhulu kwaye kunokonakala ngokukhawuleza, ngoko ke ukusebenza kwe-leaching ye-polycidin kuphantsi kakhulu, ngoko ke ingasetyenziswa kuphela ngokwengqiqo, kwaye ikhuselekile nakwimithombo yamanzi angaphantsi komhlaba.
