Kuitira kudzikisira kukanganisa kwakakonzerwa netupukanana tupukanana kuzvirimwa, isu takagadzira huwandu hwakawanda hwezvipembenene zvakasiyana. Iyo mashandiro ekuita kweakasiyana zvipembenene akafanana, saka isu tinosarudza sei iwo anonyatso kukodzera zvirimwa zvedu? Nhasi tichataura nezvezvipembenene zviviri zvine nzira dzakafanana dzekuita: imidacloprid uye thiamethoxam.
Isu varimi tinoziva kwazvo imidacloprid, saka thiamethoxam ndiyo nyowani nyuchi yekuuraya zvipembenene. Ndeapi mabhenefiti ayo pamusoro pechizvarwa chekare?
01. Musiyano wenyaya ye imidacloprid uye thiamethoxam
Kunyangwe idzo nzira mbiri dzekuita dzakafanana (dzinogona kusarudza kudzvinyirira zvipembenene zvepakati peiyo system nicotinic acid acetylcholinesterase receptor, nokudaro ichivharira kuitisa kwese kwembuyu kwehutachiona hwepakati, zvichikonzera kuoma mitezo nekufa kwezvipembenene), thiamethoxam ine 5 Kubatsira kukuru:
Thiamethoxam inoshanda zvakanyanya
Iyo yakakosha metabolite ye thiamethoxam muzvipembenene ndeye clothianidin, iyo ine hukama hwakakwira hwezvipembenene acetylcholine receptors kupfuura thiamethoxam, saka ine yakakwira yekuuraya zvipembenene.
Iko kuita kwehydroxylated metabolites ye imidacloprid yakaderedzwa.
Thiamethoxam ine yakasimba solubility mumvura
Iyo solubility ye thiamethoxam mumvura yakapetwa kasere iyo ye imidacloprid, saka kunyangwe munzvimbo isina mvura, haina kukanganisa kunwa uye kushandiswa kwe thiamethoxam negorosi.
Zvidzidzo zvakaratidza kuti muvhu rakajairika, thiamethoxam inoratidza yakafanana kudzora maitiro se imidacloprid; asi mune kusanaya kwemvura, iri nani zvakanyanya pane imidacloprid.
Yakadzika thiamethoxam kuramba
Sezvo imidacloprid yanga iri pamusika kweanoda kusvika makore makumi matatu, kukura kwekupokana kwezvipembenene kwawedzera kukura.
Sekureva kwemishumo, mhepo yebhururuka nhunzi, aphid yekotoni, uye mosquito wemhashu yechive yakagadzira kuramba kwayo.
Ngozi yekupokana nemuchinjikwa pakati pe thiamethoxam uye imidacloprid pane brownhophoppers, aphid dzedonje nezvimwe zvipembenene zvakaderera.
Thiamethoxam inogona kusimudzira kusagadzikana kwezvirimwa uye kukurudzira kukura kwezvirimwa
Thiamethoxam ine mukana wekuti zvimwe zvipembenene hazvigone kuenzana, ndiko kuti, zvine simba rekusimudzira midzi uye mbesa dzakasimba.
Zvidzidzo zvakaratidza kuti Thiamethoxam inogona kumisikidza mapuroteni kusagadzikana mapuroteni, uye panguva imwechete inogadzira auxin, cytokinin, gibberellin, abscisic acid, peroxidase, polyphenol oxidase, uye phenylalanine ammonia lyase muzvirimwa. Nekuda kweizvozvo, thiamethoxam naiyo inoita kuti mbesa stems nemidzi zviwedzere kusimba uye zvinowedzera kusagadzikana kusagadzikana.
Thiamethoxam inogara kwenguva refu
Thiamethoxam ine yakasimba shizha conduction chiitiko uye midzi systemic zvivakwa, uye mumiriri anogona kukurumidza uye kunyatso nyura.
Kana ichiiswa kune ivhu kana mhodzi, thiamethoxam inokurumidza kunwiwa nemidzi kana michero ichangotanga, uye inoendeswa kumusoro kumusoro kumativi ese emuviri wemiti kuburikidza ne xylem iri mumuviri wemiti. Inogara mumuviri wemuti kwenguva yakareba uye inoshoreka zvishoma nezvishoma. Iyo yakashatiswa chigadzirwa clothianidin ine yakakwira zvipembenene chiitiko, saka thiamethoxam ine yakareba kwenguva mhedzisiro kupfuura imidacloprid.
