Ama-pesticide avame ukuza ngezindlela ezahlukene zomthamo njenge-emulsions, i-suspensions, kanye ne-powders, futhi ngezinye izikhathi izinhlobo ezahlukene zomthamo womuthi ofanayo zingatholakala. Ngakho-ke yiziphi izinzuzo kanye nokungalungi kwezinhlobo ezahlukene zama-pesticide, futhi yini okufanele inakwe lapho isetshenziswa?
1. Izici zezakhiwo zezibulala-zinambuzane
Izibulala-zinambuzane ezingacutshungulwanga ziba izinto zokusetshenziswa, ezidinga ukucutshungulwa kanye nokwengezwa kwezithasiselo ezizosetshenziswa. Uhlobo lomthamo wesibulala-zinambuzane luncike kuqala ezimpahleni zaso ze-physicochemical, ikakhulukazi ukuncibilika kwaso kanye nesimo saso somzimba emanzini nasezincibilikisini eziphilayo.
Nakuba izibulala-zinambuzane zingacutshungulwa zibe izinhlobo ezahlukene zezilinganiso, ekusetshenzisweni okungokoqobo, uma kucatshangelwa isidingo, ukuphepha, kanye nokwenzeka kwezomnotho kokusetshenziswa, inani lezinhlobo zezilinganiso ezingacutshungulwa njengesibulala-zinambuzane lilinganiselwe.
2, Izinhlobo zezindlela zokubulala izinambuzane
①. Impuphu (DP)
Impuphu iwukulungiswa kwempuphu okunobuncane obuthile okwenziwe ngokuxuba, ukuchoboza, nokuxubanisa izinto zokusetshenziswa, izigcwalisi (noma izithwali), kanye nenani elincane lezinye izithasiselo. Okuqukethwe kwezithako ezisebenzayo zempuphu ngokuvamile kungaphansi kuka-10%, futhi ngokuvamile akudingeki ukuthi kuncishiswe futhi kungasetshenziswa ngqo ekufutheni impuphu. Ingasetshenziswa futhi ekuxubeni imbewu, ekulungiseleleni i-bait, enhlabathini enobuthi, njll. Izinzuzo kanye nokungalungi: Ayinawo umoya ohlanzekile ngokwanele, kancane kancane kunciphisa ukusetshenziswa.
②. Ama-granule (GR)
Ama-granules ayizakhi ezikhululekile ze-granular ezenziwe ngokuxuba nokufaka i-granulate izinto zokusetshenziswa, abathwali, kanye nenani elincane lezinye izithasiselo. Okuqukethwe kwezithako ezisebenzayo zale nhlanganisela kuphakathi kuka-1% no-20%, futhi ngokuvamile kusetshenziselwa ukufafaza ngqo. Izinzuzo kanye nokungalungi: Kulula ukusabalala, kuphephile futhi kuhlala isikhathi eside.
③．Impuphu emanzi (WP)
Impuphu emanzi iwuhlobo lomthamo oluyimpuphu oluqukethe izinto zokusetshenziswa, izigcwalisi noma izithwali, izinto zokumanzisa, izinto zokusabalalisa, nezinye izinto ezisizayo, futhi ifinyelela izinga elithile lobuncane ngezinqubo zokuxuba nokuchoboza. Impuphu emanzisa ingaxutshwa namanzi ukuze yakhe ukumiswa okuzinzile nokuhlakazekile kahle kokufutha. Okujwayelekile: Ama-98% adlula ngesihlungo se-mesh esingu-325, nesikhathi sokumanzisa semizuzu emi-2 yemvula encane kanye nesilinganiso sokumiswa esingaphezu kwama-60%. Izinzuzo kanye nokungalungi: igcina izinyibilikisi eziphilayo, ibonisa ukusebenza okuhle, futhi yenza kube lula ukupakisha, ukugcina, kanye nokuthuthwa.
④．Ama-granule asakazekayo ngamanzi (WG)
Ama-granule ahlakazeka ngamanzi akhiwa ngezinto zokusetshenziswa, izinto zokumanzisa, izinto zokuhlakaza, izinto zokuhlukanisa, izinto eziqinisayo, izinto zokunamathisela, izinto zokugcwalisa noma izinto zokuthwala. Uma isetshenziswa emanzini, ingahlakazeka ngokushesha futhi ihlakazeke, yakhe uhlelo lokuhlakaza oluqinile nolwelwesi olulenga kakhulu. Izinzuzo nokungalungi: Okuqukethwe okuphephile, okusebenzayo kakhulu, ivolumu encane, kanye nesilinganiso sokumiswa esiphezulu.
⑤．Amafutha e-emulsion (EC)
I-Emulsion iwuketshezi olunamafutha olufanayo nolusobala olwakhiwe ngemithi yobuchwepheshe, izinyibilikisi eziphilayo, ama-emulsifier nezinye izithasiselo. Uma isetshenziswa, ixutshwa emanzini ukuze yakhe i-emulsion eqinile yokufutha. Okuqukethwe kwe-concentrate emulsifier kungasukela ku-1% kuya ku-90%, ngokuvamile phakathi kuka-20% kuya ku-50%. Izinzuzo nokungalungi: Ubuchwepheshe buvuthiwe, futhi akukho ukusatshalaliswa noma ukuhlukaniswa ngemva kokufaka amanzi.
