Cypermetrinsisitshabalalisi esivunyiweyo ngokubanzi esihlonitshwa ngobuchule baso bokulawula iintlobo ngeentlobo zezitshabalalisi zasemakhaya.Ivela kwi-1974 kwaye yamkelwa yi-US EPA ngo-1984, i-cypermethrin iyinxalenye ye-pyrethroid ye-insecticide, ilinganisa i-pyrethrins yendalo ekhoyo kwiintyatyambo ze-chrysanthemum.Ifumaneka kwimixube eyahlukeneyo enje ngomgubo omanzi, ugxininiso lolwelo, uthuli, iiaerosols, kunye neegranules, ibonisa ukuguquguquka kuzo zonke izicelo ezahlukeneyo.

Ibulala ntoni icypermetrin?

Esi sitshabalalisi sinamandla sijolise kuluhlu olubanzi lwezinambuzane ezitshabalalisayo kuzo zonke iimeko ezahlukeneyo, ezithatha indawo yezolimo kunye neendawo zasekhaya.Ilwa ngempumelelo nezitshabalalisi zezityalo ezibandakanya iintshulube, iisemi-loopers, imibungu ye-diamond back moth, ithrips, iqakamba, iintubi, iincukuthu ezinuka kakubi, i-cutworms, kunye nezinye.Ngaphezu koko, ingqineka isebenza kwizinambuzane ezitshabalalisayo ezihlasela imithi yokuhombisa namatyholo, kwakunye nezo zihlala koovimba bokutya, kwiindawo zokugcina izityalo, nakwiindawo ezivalekileyo zezilwanyana zasekhaya.Indlela yesenzo se-Cypermethrin ibandakanya ukuphazamisa inkqubo ye-nervous central yezinambuzane ezitshabalalisayo, ukukhupha i-muscular spasms kunye nokukhubazeka, ngaloo ndlela kuphelile ekubulaweni kwabo.

I-Cypermethrin ifumana inkoliseko phakathi kweengcali zolawulo lwezinambuzane ngenxa yeziphumo zayo ezingapheliyo, kunye neendlela ezithile ezibonelela ngokhuseleko ukuya kuthi ga kwiintsuku ezingama-90.Nangona kunjalo, ezinye iingxaki zifuna ukuqwalaselwa.Nje ukuba ihlanjululwe, i-cypermethrin kufuneka isetyenziswe ngokukhawuleza ukunqanda ukuthotywa kwesithako sayo esisebenzayo.Ngaphaya koko, ayinazo iipropati ezingazigxothiyo, inyusa amathuba okuba izinambuzane zijike kwiindawo ezinyangweyo, nto leyo eyenza kube yimfuneko ukuba kusetyenziswe isicwangciso-qhinga sokuqinisekisa ukhuseleko olubanzi.

Ngaba i-cypermethrin ikhuselekile kubantu, izinja kunye neekati?

Ngokokhuseleko,I-cypermethrin ayinabungozi kubantu nakwizilwanyana zasekhaya xa iqeshwe njengoko kuyalelwe, nangona ubulumko bufanelekile.Ngelixa ibeka ubutyhefu obuncinci ebantwini nakwizilwanyana, iikati zibonisa ubuntununtunu obuphakamileyo kwi-pyrethroids efana ne-cypermethrin, inyanzelisa ukukhutshwa kwabo kwiindawo ezinyangweyo kunye nasemva kokufakwa kwesicelo.Ukuthobela imiyalelo yelebhile, ukusetyenziswa kwezixhobo ezifanelekileyo zokuzikhusela ngexesha lokufaka isicelo, kunye nokugcinwa ngokukhuselekileyo kude nabantwana kunye nezilwanyana zasekhaya kubalulekile.

Ukuququmbela

I-Cypermethrin ivela njengesitshabalalisi esisebenzayo esiqhayisa ngokusebenza okubanzi ngokuchasene nezitshabalalisi zasekhaya kunye nabachasi bezityalo zezolimo.Ukusetyenziswa kwayo ngobuchule kuyinika ithuba elithandwayo phakathi kwabasebenzi bolawulo lwezinambuzane kunye nabanini-zindlu ngokufanayo, ibonelela ngolawulo oluhlala luhleli kunye nothintelo ngokuchasene nokuhlaselwa kwezinambuzane ezingamkelwanga.

Sisebenza ngokukhethekileyo ekunikezeni amayeza okubulala izinambuzane kubahambisi bezolimo okanye abathengisi behlabathi jikelele, kwaye siyakwazi ukubonelela ngeesampulu kwimixube eyahlukeneyo.Ukuba usenemibuzo malunga necypermethrin, zive ukhululekile ukunxulumana nathi ngembalelwano.
