Kwiminyaka yakutshanje, kuye kwaba nzima ngakumbi ukukhusela izitshabalalisi zezityalo, kwaye ukungakhathali okuncinci kuya kukhokelelaisivuno esincinci kunye nomvuzo omncinci.Ngoko ke, ukuze kuncitshiswe umonakalo kwisityalo sezinambuzane ezitshabalalisayo, siye savelisa ngokwahlukileyoamayeza okubulala izinambuzane. Hsingakwazi njani ukukhetha eyona nto ifanele izityalo zethu?Ngeli xeshamandikwazise iThiamethoxam .
Indlela yokunyanga:
I-Thiamethoxam ikakhulu i-acetylcholinase esebenza kwinkqubo ye-nervous yezinambuzane ukuvuselela iiprotheni ze-receptor.Le acetylcholine ixeliweyo ayithotywanga yi-acetylcholine, ibangela ukuba inambuzane ibe nemincili kakhulu de kube sekufeni.
Ntlanuubukhulu becalainzuzos ye Ti-hiamethoxam:
1. Umsebenzi ophezulu. Iimetabolites eziphambili zeThiamethoxam kumzimba wezinambuzane kukho i-tetramine.I-affinity ye-acetylcholine receptor yezinambuzane iphezulu kune-cycamine, ngoko inomsebenzi ophezulu we-insecticidal.Undoqo
2. Ukunyibilika okuphezulu emanzini. Iqondo elinyibilikayo leThiamethoxam emanzini ngamaxesha angama-8 e-nagin, ngoko ke nakwimeko yembalela, ayichaphazeli ukufunxa kunye nokusetyenziswa kwengqolowa.Uphando lubonise ukuba kwimihlaba eqhelekileyo efumileyo,Thiamethoxam ibonisa imiphumo efanayo yokuthintela kunye nonyango njenge-nagin;
3. Inqanaba eliphantsi lokumelana.Phantse iminyaka engama-30 ukususela kuluhlu lweThiamethoxam, uphuhliso oluchasene neziyobisi lwezinambuzane luye lwaba lukhulu ngakumbi.Ngokutsho kweengxelo, umoya ophaphazelayo omdaka (brown-flying wind), iintwala zomqhaphu, iilikhi kunye netshive ziyakwazi ukuxhathisa.Umngcipheko wokulindela okufana ne-brown-aversion kunye ne-cotton aphids iphantsi kakhulu.
4. Inokomeleza ukuxhathisa kwezityalo kwaye ikhuthaze ukukhula kwesityalo. Thiamethoxam kananjalo inenzuzo enganelisiyo ukuba ezinye izibulali-zinambuzane azinakuthelekiswa nayo, nto leyo indima yokukhuthaza iingcambu.Ucwaningo luye lwabonisa ukuba i-molaristzine inokulindela iprotheni, kwaye kwangaxeshanye, inefuthe kwimpembelelo yomzimba womzimba, isahlulo seseli, i-gibbererin, i-peroxidase, i-polyphenol oxidase, i-phenylalanine, i-Tiezine ukuqhubela phambili. ukwenza isiqu kunye nenkqubo yeengcambu zomelele ngakumbi, ukomeleza ukuxhathisa.
5. Isiphumo esihlala ixesha elide. I-Thiamethoxam inamagqabi anamandla kunye nokufunxa kwangaphakathi kwingcambu, kwaye amayeza anokukhawuleza kwaye afakwe ngokupheleleyo.Xa igalelwa emhlabeni okanye imbewu.Thiamethoxam ifunxeka ngokukhawuleza yingcambu okanye izithole ezintshulayo.Iinxalenye zokhuni kwisityalo zithuthwa ukuya kumzimba wesityalo.Iimveliso ezonakeleyo zivulwe ngakumbi yiThiamethoxamkunye nokubulawa kwezinambuzane.
