Imidaclopridmushonga wezvipembenene unonzi nitromethylene systemic, uri muchikamu chemishonga yezvipembenene inonzi nicotinyl inonzi chlorinated, inozivikanwawo semushonga wezvipembenene unonzi neonicotinoid, une fomura yemakemikari inonzi C9H10ClN5O2. Une spectrum yakakura, unoshanda zvakanyanya, huturu hushoma uye hushoma, uye hazvisi nyore kuti zvipembenene zvirambe zvichirwisa zvipembenene. Unogona kukanganisa mashandiro etsinga dzemuviri, kuita kuti kutapurirana kwezviratidzo zvemakemikari kukundikane, uye kukonzera kuoma mitezo nerufu rwezvipembenene.
Mushonga uyu unoshanda nekukurumidza, uye unodzivirira zvakanyanya zuva rimwe chete mushure mekushandisa mushonga uyu, uye nguva yasara inosvika mazuva makumi maviri nemashanu. Unonyanya kushandiswa kudzora zvipembenene zvinoyamwa zvinoboora.
Kudzora zvipembenene zvinoyamwa zvinoboora pamwe nemarudzi azvo anoramba kumera. Ine hunhu hunotevera:
(1) Hunhu hwakafara, hunoshanda zvakanyanya uye hunogara kwenguva refu. Hune simba rakanaka kwazvo rekudzivirira maaphid, horsefish nezvimwe zvipembenene zvezvipembenene zvinobaya muromo uye coleopteran. Hunogona zvakare kushandiswa kudzora manyoka muzvivako nenhata pamhuka dzinovaraidza dzakadai semakatsi nembwa. Kazhinji, 1-2 gramu yezvinhu zvinoshanda zvinogona kushandiswa pamwedzi wega wega kuti uwane simba rinogutsa rekudzivirira, uye nguva inoshanda inogona kugara kwemavhiki akati wandei. Kushandiswa kamwe chete kunogona kudzivirira zvirimwa kubva kuzvipembenene mumwaka wese wekurima.
(2) Yakakodzera kurapa ivhu nembeu. Ine chepfu mudumbu uye inouraya zvipembenene. Kurapa ivhu kana mbeu neimidacloprid, nekuda kwehunhu hwayo hwakanaka hwemuviri, metabolites mushure mekutorwa nemidzi yemiti uye kupinda mumiti dzine basa guru rekuuraya zvipembenene, kureva kuti, imidacloprid nemetabolites dzayo pamwe chete zvinouraya zvipembenene, saka simba rekutonga rinoshanda zvakanyanya. Imidacloprid inogonawo kusanganiswa nemishonga inouraya zvipembenene kana ikashandiswa pakurapa mbeu.
(3) Maitiro ekuuraya zvipembenene akasiyana. Inhengo yetsinga, uye chinangwa chayo i nicotinic acid acetylcholinesterase receptor iri mu post-synaptic membrane yetsinga dzezvipembenene, iyo inokanganisa kukurudzira kwakajairika kwetsinga dzezvipembenene, zvichikonzera kuoma mitezo nerufu. Izvi zvakasiyana nemishonga yezvipembenene yechinyakare. Saka, kune zvipembenene zvisingapindire ku organophosphorus, carbamate, uyemishonga yezvipembenene inonzi pyrethroid, imidacloprid ichiri nemhedzisiro iri nani yekudzora. Ine hukama huri pachena kana ikashandiswa kana kusanganiswa nemhando nhatu idzi dzemishonga yekuuraya zvipembenene.
(4) Zviri nyore kukonzera kuti zvipembenene zvisave nemishonga. Nekuda kwenzvimbo imwe chete yazvinoita, zvipembenene zvinowanzova nemishonga. Kushandiswa kwacho kunofanira kudzorwa panguva yekushandiswa. Zvinorambidzwa zvachose kuishandisa kaviri mumutsara pachirimwa chimwe chete. Mamwe marudzi emishonga yekuuraya zvipembenene.
