Ama-aphid angenye yezilokazane eziphambili zezilimo, ezinhlobo eziningi zezilwane, izizukulwane eziningi, ukukhiqizwa kabusha okusheshayo nokulimala okungathi sína. Ngokumunca i-sap yezilimo, izilimo zibuthakathaka futhi zibuna, futhi ngasikhathi sinye, ama-aphid angasakaza namagciwane ahlukahlukene, adale ukulahleka okukhulu. Ngenxa yobukhulu obuncane be-aphid, ukukhiqizwa kabusha okusheshayo, nokusetshenziswa kwezidakamizwa okungenangqondo, ukumelana kukhula ngokushesha nangokushesha.
Imikhuba Ephila
Ama-aphid alimazayo wonke unyaka wonke futhi abe nomthamo wokuzala oqinile. Baphindaphinda okusheshayo emazingeni okushisa azungeze ama-29 ° C. Kungavuselela izizukulwane eziyi-10 kuye kwezingama-30 ngonyaka, futhi into yezizukulwane ezigcwele kakhulu iyavelele. Ama-aphid abesifazane ayazalwa evundile. Futhi ama-aphid awadingi abesilisa ukuthi bakhulelwe (ie, parthenogenetic).
Ifomula ejwayelekile ye-aphid engamelana nayo
1.PPymetrozine · I-dinotefuran
Ngaphezu kokuthintwa khona ukubulala kanye nemiphumela yokufaka ubuthi besisu, futhi ine-ejenti yezinzwa enhle kanye nomphumela osheshayo wokulwa nokuchapha. Ngemuva kwama-aphid nezinye izinambuzane zokubhoboza zidla futhi zidonsa ujusi wesitshalo nge-flonicamid, zizovinjelwa ngokushesha ekunciphiseni ujusi, futhi akukho ukukhishwa okuzovela kungakapheli ihora eli-1, futhi ekugcineni kufa yindlala.
2.flonicamid · acetamiprid
Ngoba indlela yalo yokusebenza yehlukile kwaleyo yezinambuzane ezijwayelekile, inemiphumela ekhethekile kuma-aphid amelana nama-organophosphates, ama-carbamate kanye nama-pyrethroids. Isikhathi sokuqinisekisa singafinyelela ngaphezu kwezinsuku ezingama-20.
3.flonicamid · thiamethoxam
Okokufafaza kwe-foliar kanye nokunisela kwenhlabathi kanye nokwelashwa kwezimpande. Itholwa ngokushesha ngohlelo ngemuva kokufafaza, futhi idluliselwa kuzo zonke izingxenye zesitshalo, esinomphumela omuhle wokulawula izinambuzane ezinamathela ezinambuzaneni ezifana nama-aphid, amaplaphu, amaqabunga.
I-4.FlonicamiD · dinotefula
Inezimpawu zokubulawa kokuxhumana, ubuthi besisu, ukumuncwa kwezimpande eziqinile, umphumela osheshayo wezimpande, isikhathi esihlala isikhathi eside samaviki angama-4-8 (umphumela ovuthayo we-theoretical yizinsuku ezingama-43), njll., Futhi unomphumela omuhle kakhulu wokulawula ekubhobozeni nasezincebeni zomlomo izinambuzane.
5.Spirotetramat · phymetozine
Inomsebenzi ohlukile wendlela ehlukile, ingafinyelela ngempumelelo zonke izingxenye zomzimba wesitshalo, ine-insecticidal deplyrum, futhi inomsebenzi ophakeme kumaqanda, ama-nymphs kanye nabantu abadala. Kufika ezinsukwini ezingama-25 noma ngaphezulu.
I-6.Spirotetramat · Avermectin
Inezinhlelo ezinhle, ingaqhuba i-bitirectional conduction ngokusebenzisa i-xylem ne-phloem, futhi inemiphumela ekhethekile ku-Preyllium ne-peach aphid; Umphumela uyashesha futhi ubude besikhathi sesikhathi eside, futhi ukufa kwezinambuzane ezindala kuya ezinsukwini ezi-3 kuye kweziyi-5, futhi isikhathi sohlelo lokusebenza olulodwa singafinyelela ku-25 kunganciphisa ngokuphumelelayo imvamisa yokwelashwa nokugcina isikhathi nokusebenza; Ukuhambisana okuhle, ifomu lokumiswa komthamo, inani le-PH VARE, lingahlanganiswa namalungiselelo amaningi emakethe, asikho isidingo sokukhathazeka ngezinkinga zokuphepha; Indlela yokubambisana kwezinto ezimbili inganciphisa ngempumelelo ingozi yokumelana nokubulala izinambuzane; I-coufflity yobuthi benobuthi ezinambuzaneni kanye nezibungu ziphakeme, futhi i-synergy ehlanganisiwe ibalulekile. Ukusindisa isikhathi, ukusindisa isikhathi, ukulondolozwa kwabasebenzi, kanye nomphumela wokuvimbela isikhathi eside.
