Iko kusanganiswa kweneonicotinoid mishonga yezvipembenene nemamwe mishonga yakaratidzawo yakanakisa kudzora mhedzisiro.Inogona kuonekwa kubva paTebhu 3 kuti apo imidacloprid uye thiamethoxam zvakasanganiswa ne tebuconazole semishonga yekurapa mbeu, migumisiro yekutonga pagorosi aphid yakanga yakanaka kwazvo, uye isina chinangwa Biosafety apo ichivandudza kumera kwembeu.Kugadzirira kwemusanganiswa kwemidacloprid, triazolone uye dinconazole kwakaratidza kushanda kwakanaka mukutonga kwezvirwere zvegorosi uye zvipembenene.%～99.1%.Kusanganiswa kwemishonga yezvipembenene neonicotinoid uye syringostrobin (1∶20～20∶1) ine synergistic effect padonje aphid.Kana huwandu hwehuwandu hwe thiamethoxam, dinotefuran, nitenpyram uye penpyramid iri 50: 1-1: 50, co-toxicity coefficient iri 129.0-186.0, iyo inogona kudzivirira nekudzora zvinobaya-inoyamwa tupukanana pamuromo.Apo reshiyo ye epoxifen ne phenoxycarb yaiva 1:4, co-toxicity coefficient yaiva 250.0, uye simba rekutonga parice planthopper ndiro rakanyanya kunaka.Iko kusanganiswa kwemidacloprid uye amitimidine kwaive kwakajeka inhibitory effect pakotoni aphid, uye chiyero che synergy chaive chepamusoro apo imidacloprid yaive yakaderera muyero weLC10.Apo huwandu hwehuwandu hwe thiamethoxam uye spirotetramat hwakanga huri 10: 30-30: 10, co-toxicity coefficient yaiva 109.8-246.5, uye pakanga pasina phytotoxic effect.Pamusoro pezvo, zvicherwa zvemafuta ezvipembenene greengrass, diatomaceous pasi uye mamwe mishonga yezvipembenene kana adjuvants akasanganiswa neonicotinoid mishonga yezvipembenene anogona zvakare kuvandudza maitiro ekutonga pane zvinotangwa zvipembenene.
Iko kushandiswa kwemamwe mishonga yezvipembenene kunonyanya kusanganisira triazoles, methoxyacrylates, nitro-aminoguanidines, amitraz, quaternary keto acids, mineral oils uye diatomaceous earth, nezvimwewo. mhando dzemishonga yezvipembenene.Mienzaniso inobatanidza inoratidzawo kuti mhando dzakawanda dzemishonga yezvipembenene dzinogona kusanganiswa neonicotinoid mishonga yezvipembenene, ichipa dzimwe sarudzo dzekudzora zvipembenene.
10 Mhedziso uye Outlook
Kushandiswa kwakapararira kwemishonga yezvipembenene neonicotinoid kwakonzera kuwedzera kukuru kwekupokana kwezvipembenene zvinotarirwa, uye kusazvibata kwavo kwezvakatipoteredza uye njodzi dzekufumurwa kwehutano dzave nzvimbo dzazvino dzekutsvagisa uye matambudziko ekushandisa.Iko kurongeka kusanganiswa kwemishonga yezvipembenene yakasiyana kana kugadzirwa kwezvipembenene synergistic agents chiyero chakakosha kunonoka kuramba zvinodhaka, kuderedza kushandiswa uye kuwedzera kushanda zvakanaka, uye zvakare zano guru rekushandisa kwakasimba kwemishonga yakadai mukugadzirwa chaiko kwekurima.Pepa rino rinoongorora mafambiro ekushandiswa kwemishonga yezvipembenene neonicotinoid pamwe chete nemamwe marudzi emishonga yezvipembenene, uye rinojekesa zvakanakira kusanganisa mishonga yezvipembenene: ① kunonoka kuramba zvinodhaka;② kunatsiridza kudzora maitiro;③ kuwedzera kudzora spectrum;④ kuwedzera nguva yekuita;⑤ kunatsiridza kukurumidza kuita ⑥ Rongedza kukura kwezvirimwa;⑦ Kuderedza kushandiswa kwemishonga yezvipembenene;⑧ Kuvandudza njodzi dzezvakatipoteredza;⑨ Kuderedza mari yehupfumi;⑩ Kuvandudza mishonga yezvipembenene.Panguva imwecheteyo, kutarisisa kwakanyanya kunofanirwa kubhadharwa kune yakasanganiswa kuratidzwa kwezvakatipoteredza kwezvakaumbwa, kunyanya kuchengetedzwa kwezvisina chinangwa zvipenyu (semuenzaniso, vavengi vezvipembenene) uye zvirimwa zvinonzwisisika pamatanho ekukura akasiyana, pamwe nenyaya dzesainzi dzakadai. semisiyano yekudzora mhedzisiro inokonzerwa nekuchinja kwemakemikari maitiro ezvipembenene.Kugadzirwa kwemishonga yechinyakare kunotora nguva uye kushanda nesimba, nekudhura kwakanyanya uye kutenderera kwenguva refu kwekutsvaga nekusimudzira.Sechimwe chiyero chinoshanda, kusanganisa kwemishonga yezvipembenene, kushandisa kwayo zvine musoro, kwesainzi uye kwakamisikidzwa hakungorebesi chete kutenderera kwekushandisa kwemishonga yezvipembenene, asi zvakare inosimudzira kutenderera kwakanaka kwekudzora zvipembenene.Kubudirira kwakasimba kwezvakatipoteredza kunopa tsigiro yakasimba.
