Iyini imiphumela nemisebenzi ye-Tetramethrin ne-Permethrin?

Kokubilii-permethrinfuthii-cypermethrinziyizibulala-zinambuzane. Imisebenzi kanye nemiphumela yazo ingafingqwa kanje:

1. I-Permethrin

1. Indlela yokusebenza: I-Permethrin ingeyesigaba se-pyrethroid semithi yokubulala izinambuzane. Iphazamisa kakhulu uhlelo lokuhambisa izinzwa lwesinambuzane, inomphumela wokubulala othintanayo kanye nomphumela onamandla wokuwisa phansi. Isebenza kahle kakhulu ezinambeni zasekhaya ezifana nomiyane, izimpukane, namaphela, kodwa inomphumela omubi kancane wokubulala amaphela. Ivame ukusetshenziselwa ukuxosha.

2. Ububanzi bokusetshenziswa: Njengoba umphumela we-permethrin kuphela ungabalulekile kakhulu, ivame ukuhlanganiswa nezinye izibulala-zinambuzane ezinamandla amakhulu okubulala izinambuzane kanye nobuthi obuphansi kubantu nasezilwaneni ukuze kwakheke ama-spray noma ama-aerosol agents, futhi isetshenziswa kabanzi emakhaya nasezindaweni zezempilo zomphakathi.

3. Ubuthi: I-Permethrin iyi-insecticide enobungozi obuphansi. Ngokusho kwedatha yokuhlolwa kwezilwane, i-LD50 yomlomo ebukhali yamagundane ingu-5200mg/kg, kanti i-LD50 yobuso obukhulu ingaphezu kuka-5000mg/kg, okubonisa ukuthi ubuthi bayo bomlomo nobuso buphansi kakhulu. Ngaphezu kwalokho, ayinawo umphumela wokucasuka esikhumbeni nasemahlweni, futhi ayikho imiphumela ebangela umdlavuza noma yokuguqulwa etholakale ekuzalweni kwamagundane isikhathi eside. Kodwa-ke, inobuthi obukhulu ezinyosini nasezimbongolweni zesilika.

2. I-Cypermethrin

1. Indlela yokusebenza: I-Cypermethrin iphinde ibe yi-insecticide engenabo ubuthi obuncane enemiphumela yobuthi bokuthintana kanye nesisu. Ibulala izinambuzane ngokuphazamisa uhlelo lokuhambisa izinzwa lwesinambuzane futhi inomphumela oqinile wokudiliza kanye nesivinini sokubulala ngokushesha.

2. Ububanzi bokusetshenziswa: I-Cypermethrin isetshenziswa kabanzi emkhakheni wezolimo futhi ingasetshenziswa ukulawula izinambuzane ezitshalweni ezahlukahlukene njengemifino, itiye, izihlahla zezithelo, kanye nekotini, njengezibungu zeklabishi, ama-aphid, izikelemu zekotini, njll. Ngesikhathi esifanayo, inemiphumela emihle nasezilokazaneni zasekhaya ezifana nomiyane, izimpukane, izinambuzane, namaphela.

3. Ubuthi: Nakuba i-cypermethrin iyi-insecticide enobungozi obuphansi, kufanele kuqashelwe ngesikhathi sokusetshenziswa. Uma ifuthwe ngephutha ebusweni besikhumba, kufanele igezwe ngensipho ngesikhathi; uma igwinywe ngephutha, ingabangela izimpawu zobuthi njengokuhlanza, ubuhlungu besisu, kanye nesifo sohudo. Ngakho-ke, uma usebenzisa i-cypermethrin, kufanele kulandelwe imithethonqubo yokuphepha efanele futhi kufanele igcinwe kahle ukuze kugwenywe izingozi.

Ngamafuphi, kokubili i-permethrin ne-cypermethrin ziyizibulala-zinambuzane ezisebenza kahle futhi ezinobuthi obuphansi futhi zinobubanzi bokusetshenziswa. Uma uzisebenzisa, kubalulekile ukukhetha isibulala-zinambuzane esifanele ngokwezidingo nezimo ezithile, bese ulandela imithethonqubo yokusebenza kokuphepha efanele.
