Umgangatho ophezulu we-Spinosad CAS 131929-60-7 kunye nokuhanjiswa ngokukhawuleza

Ingcaciso yeMveliso

I-Spinosad yityhefu ephantsi, ukusebenza kakuhle,I-fungicide ebanzi.Kwaye sele isetyenziswa kwihlabathi jikeleleulawulo lweentlobo ngeentlobo zezinambuzane ezitshabalalisayo, kuquka iLepidoptera, iDiptera, iThysanoptera, iColeoptera, iOrthoptera kunye neHymenoptera, kunye nabanye abaninzi.I-Spinosad ikwajongwa njengemveliso yendalo, ngoko ivunyiwe ukuba isetyenziswe kulimo oluphilayo ziintlanga ezininzi.

Ukusebenzisa Iindlela

1. Yemifunoabalawuli berhorhoye-diamondback nundu, sebenzisa i-2.5% yokuxhoma i-agent 1000-1500 amaxesha esisombululo sokutshiza ngokulinganayo kwinqanaba le-larvae eselula, okanye usebenzise i-2.5% yokumisa i-33-50ml ukuya kwi-20-50kg yesitshizi samanzi rhoqo ngama-667m.².

2. Ukulawula intshulube ye-beet armyworm, fafaza amanzi nge-2.5% ye-suspension agent 50-100ml qho kwi-667 square metres kwisigaba sokuqala sombungu, kwaye esona siphumo singcono ngokuhlwa.

3. Ukuthintela kunye nokulawula i-thrips, rhoqo kwi-667 square metres, sebenzisa i-2.5% yokumisa i-agent 33-50ml ukutshiza amanzi, okanye usebenzise i-2.5% yokumisa i-agent 1000-1500 amaxesha olwelo ukutshiza ngokulinganayo, ugxininise kwizicubu ezincinci ezifana neentyantyambo, ezincinci. iziqhamo, iingcebiso kunye namahlumela.

Ukuqwalaselwa

1. Isenokuba netyhefu kwiintlanzi okanye kwezinye izinto eziphila emanzini, kwaye ukungcoliseka kwemithombo yamanzi kunye namachibi kufuneka kuphetshwe.

2. Gcina iyeza kwindawo epholileyo neyomileyo.

3. Ixesha eliphakathi kokufakwa kokugqibela kunye nokuvuna ziintsuku ezisi-7.Kuphephe ukudibana nemvula kwiiyure ezingama-24 emva kokutshiza.

4. Nika ingqalelo kukhuseleko lomntu siqu.Ukuba itshiza emehlweni, yihlambulule ngokukhawuleza ngamanzi amaninzi.Ukuba udibana nesikhumba okanye impahla, hlamba ngamanzi amaninzi okanye ngamanzi anesepha.Ukuba kuthathwe ngempazamo, musa ukukuhlanza ngokwakho, ungadli nantoni na okanye ufune ukugabha kwizigulana ezingavukiyo okanye ezine-spasms.Isigulane kufuneka sithunyelwe ngokukhawuleza esibhedlele ukuze sifumane unyango.

Indlela yokusebenza

Indlela yokwenza i-polycidin iyinveli kakhulu kwaye iyingqayizivele, eyahlukileyo kwi-macrolides jikelele, kwaye isakhiwo sayo samakhemikhali esiyingqayizivele sinquma indlela yayo ekhethekileyo ye-insecticidal.I-Polycidin inoqhagamshelwano olukhawulezayo kunye ne-toxicity yokungenisa kwizinambuzane.Ineempawu ezinobuthi ezizodwa ze-nerve agents.Indlela yayo yokusebenza kukukhuthaza inkqubo ye-nervous yezinambuzane, ukwandisa umsebenzi wayo ozenzekelayo, kwaye ikhokelela ekunqanyulweni kwemisipha engasebenziyo, ukungaphumeleli, kunye nokugungqa kunye nokukhubazeka.Kwaboniswa ukuba i-nicotinic acetylcholine receptor (nChR) yayisebenza ngokuqhubekayo ukuze yenze ukukhululwa kwe-acetylcholine (Ach) ende.I-Polycidin iphinda isebenze kwi-γ-aminobutyric acid (GAGB) receptors, iguqula umsebenzi we-GABA gated chlorine channels kunye nokuphucula ngakumbi umsebenzi wayo wokubulala izinambuzane.

Indlela yokunciphisa

Intsalela yezibulali zinambuzane kwindawo engqongileyo ibhekisa “kumthwalo omkhulu” wemichiza yokutshabalalisa izinambuzane ezinokuthi ziqulathwe yimekobume, oko kukuthi, kummandla othile nakwixesha elithile, ukuze kuqinisekiswe umgangatho webhayoloji kunye nesivuno seemveliso zezolimo kunye nokungaphuli imveliso yezolimo. umgangatho wokusingqongileyo."Ubukhulu bomthwalo" bukwayixabiso lomqobo lokulinganisa ukhuseleko lokusingqongileyo lwe-pesticides, kwaye lukwaguquguqukayo olunciphisa ngokuthe ngcembe ngokutshintsha kwexesha kunye neemeko zokusingqongileyo.Lo gama nje ingadluli kulo mda, into yokhuseleko lokusingqongileyo ye-pesticides ifanelekile.I-Polycidin iyancipha ngokukhawuleza kwimo engqongileyo ngeendlela ezahlukeneyo zokudibanisa, ngokukodwa ukuchithwa kweefoto kunye nokutshatyalaliswa kwe-microbial, kwaye ekugqibeleni ibolile ibe yizinto zendalo ezifana nekhabhoni, i-hydrogen, i-oksijini, kunye ne-nitrogen, ngaloo ndlela ingabangela ukungcola kwendalo.I-photodegradation yesiqingatha sobomi be-polycidin emhlabeni yayiyi-9 ~ 10 iintsuku, ezo zomphezulu wamagqabi zaziyi-1.6 ~ 16 iintsuku, kwaye ezo zamanzi zazingaphantsi kosuku olu-1.Ewe, isiqingatha sobomi sinxulumene nokuqina kokukhanya, ngokungabikho kokukhanya, isiqingatha sobomi be-multicidin ngumhlaba we-aerobic metabolism yi-9 ukuya kwiintsuku ze-17.Ukongezelela, i-coefficient yokudlulisa ubunzima bomhlaba we-polycidin iphakathi K (5 ~ 323), ukunyibilika kwayo emanzini kuphantsi kakhulu kwaye kunokutshatyalaliswa ngokukhawuleza, ngoko ke ukusebenza kwe-polycidin kuphantsi kakhulu, ngoko kunokusetyenziswa kuphela ngokufanelekileyo. kwaye ikwakhuselekile nakwimithombo yamanzi angaphantsi komhlaba.
