Ai-systemic insecticideikhemikhali emuncwa isitshalo futhi iqhutshwe kuwo wonke umzimba wesitshalo. Ngokungafani nama-insecticide angewona ama-systemic, ama-insecticide e-systemic awagcini nje ngokusebenza phezu kwesifutho, kodwa ahanjiswa ngezimpande, iziqu, namahlamvu esitshalo, ngaleyo ndlela enze umgoqo wokuzivikela kuso sonke isitshalo.
Indlela Ama-Insecticide Asebenza ngayo
Ama-systemic insecticide amuncwa ngohlelo lwezimpande zesitshalo bese kuthi kamuva ahanjiswe ngohlelo lwemithambo yesitshalo aye kuzo zonke izingxenye zesitshalo. Izinambuzane ezidla izicubu zezitshalo eziqukethe ama-insecticides zishesha ukufakwa ubuthi futhi ziyafa. Lesi sakhiwo esisebenzayo se-systemic insecticide sibenza baphumelele ngokumelene nezinambuzane ezifihlekile ngaphakathi kwesitshalo noma okunzima ukufinyelela kuzo endaweni yesitshalo.
Ukuqala ukusebenza kwama-insecticides esistimu
Ukuqala kokusebenza kwama-systemic insecticide kuncike ezintweni eziningi, okuhlanganisa uhlobo lwesitshalo, izimo zemvelo, nokwakhiwa kwesibulala-zinambuzane. Ngokuvamile, izibulala-zinambuzane ezihleliwe zisebenza kahle phakathi namahora ambalwa kuya ezinsukwini ngemva kokufakwa, futhi izinambuzane ziyafa ngokushesha ngemva kokuwagwinya.
Isikhathi sokuphikelela kwama-insecticide e-systemic
Ubude besikhathi somphumela we-systemic insecticide esitshalweni buphinde buthintwa yizinto eziningi. Ngokuvamile, imiphumela ye-systemic insecticide ihlala emasontweni ambalwa kuya ezinyangeni ezimbalwa, okusho ukuthi isitshalo singaqhubeka nokulwa nokuhlasela kwezinambuzane ngalesi sikhathi, ukunciphisa isidingo sokufafaza ngokuphindaphindiwe.
Indlela yokusebenzisa ama-insecticide e-systemic
Ama-systemic insecticide asetshenziswa ngezindlela ezahlukahlukene, kufaka phakathi ukufaka umhlabathi, izifutho zefoliar kanye nemijovo yesiqu. Ngezansi kunezindlela ezimbalwa ezijwayelekile zohlelo lokusebenza:
Ukufakwa kwenhlabathi: isisombululo se-insecticide sithelwa enhlabathini ezungeze izimpande zesitshalo, futhi isitshalo simunca isibulala-zinambuzane ngesistimu yaso yezimpande.
Ukufafaza ngama-Foliar: Isixazululo se-insecticide sifafazwa emaqabunga esitshalo bese isibulala-zinambuzane simunca emaqabunga.
Umjovo we-trunk: Izibulala-zinambuzane zijovwa ngqo esiqwini sesihlahla ukuze ziqhutshwe ngokushesha kuso sonke isitshalo.
Izincomo Ezinhle Zokubulala Izinambuzane
Njengoba kunezinhlobonhlobo zezibulala-zinambuzane ezihleliwe ezitholakala emakethe, kubalulekile ukukhetha umkhiqizo ongcono kakhulu ngokwezidingo zakho ezithile. Nazi izibulala-zinambuzane ezimbalwa ezisebenza kahle kakhulu zesistimu:
Imidacloprid: isibulala-zinambuzane esibanzi esilungele izinhlobo eziningi zezitshalo futhi singalawula ngempumelelo ama-aphid, izimpukane nezinye izinambuzane.
I-Acetamiprid: insecticide enamandla yama-aphid, izimpukane ezimhlophe, njll. Ifanele izithelo, imifino kanye nezitshalo zokuhlobisa.
I-Thiamethoxam: Ubuthi obusebenza kahle kakhulu nobuphansi, obusebenza ezinhlobonhlobo zezitshalo, bungavikela izitshalo ezinambuzaneni isikhathi eside.
Ukusetshenziswa kwama-insecticide e-systemic emifino
Nakuba ama-systemic insecticide esetshenziswa kakhulu ezitshalweni, adinga ukusetshenziswa ngokuqapha okwengeziwe emifino. Ngenxa yokuthi ama-systemic insecticide amuncwa isitshalo, isikhathi esanele sokuphepha sidinga ukuvunyelwa ngaphambi kokuvuna ukuze kuqinisekiswe ukuphepha komkhiqizo.
Imiphumela ye-systemic insecticide ezinyosini
Ama-systemic insecticide angase abe yingozi ezinambuzaneni ezifaka impova njengezinyosi. Ukuze uvikele izinyosi, kunconywa ukugwema ukusetshenziswa kwezinambuzane ze-systemic ngesikhathi sokuqhakaza futhi ukhethe ezinye izibulala-zinambuzane ezinobuthi obuphansi noma obungenabo ezinyosini.
Ingabe ama-insecticides angakwazi ukubulala izibungu zesicabucabu
Amanye ama-insecticide e-systemic ayasebenza ngokumelene nezibungu zesicabucabu, kodwa akuyona yonke imikhiqizo enalo mphumela. Uma kudingeka, sizoncoma ama-insecticide amahhala azolawula ngempumelelo izibungu zesicabucabu.
Ingabe ama-insecticide angewona amasistimu aphephile
Izibulala-zinambuzane ezingezona zesistimu zisebenza kuphela endaweni efuthwe futhi ngokuvamile ziwohloka ngokushesha endaweni, ngakho zingase ziphephe kunezibulala-zinambuzane ezihleliwe kwezinye izimo. Kodwa-ke, ama-insecticide angenayo i-systemic adinga ukusetshenziswa njalo futhi kunzima ukuwasebenzisa ukulawula ngokuphelele izinambuzane ezicasha ngaphakathi kwesitshalo.
