BifenthrinIli ndi zotsatira zopha anthu komanso poizoni m'mimba, zomwe zimakhala ndi zotsatira zokhalitsa. Imatha kulamulira tizilombo tomwe timakhala pansi pa nthaka monga mphutsi, nyongolotsi, ndi mphutsi za m'madzi, tizilombo tomwe timakhala m'masamba monga nsabwe za m'masamba, mphutsi za kabichi, ntchentche zoyera za m'nthaka, akangaude ofiira, ndi nthata zachikasu za tiyi, komanso tizilombo tomwe timakhala m'mitengo ya tiyi monga nyongolotsi za tiyi, nyongolotsi za tiyi, ndi njenjete yakuda ya tiyi. Pakati pa izi, nsabwe za m'masamba, nyongolotsi za kabichi, akangaude ofiira ndi tizilombo tina tomwe timakhala m'masamba tingathe kulamulidwa popopera mankhwala a bifenthrin ochepetsedwa ka 1000 mpaka 1500.
I. Ntchito yabifenthrin
Bifenthrin ili ndi mphamvu yopha anthu ndi poizoni m'mimba, siigwira ntchito m'thupi lonse kapena kuigwiritsa ntchito ngati fumigation, imathamanga kwambiri, imakhala ndi mphamvu yokhalitsa, komanso imakhala ndi mankhwala ambiri ophera tizilombo. Imagwiritsidwa ntchito kwambiri polimbana ndi mphutsi za lepidoptera, ntchentche zoyera, nsabwe za m'masamba, ndi akangaude odya zomera ndi tizilombo tina.
II. Ntchito zabifenthrin
1. Lawani tizilombo tomwe timawononga mbewu monga mavwende ndi mtedza, monga mphesa,nyongolotsi, ndi nyongolotsi za waya.
2. Lamulani tizilombo towononga zomera monga nsabwe za m'masamba, njenjete za diamondback, nyongolotsi za diamondback, nyongolotsi za beet armyworms, nyongolotsi za kabichi, ntchentche zoyera za greenhouse, nthata zofiira za biringanya ndi nthata zachikasu za tiyi.
3. Lamulani tizilombo towononga mitengo ya tiyi monga tiyi looper, mbozi ya tiyi, njenjete ya tiyi yakuda, njenjete ya tiyi ya thorn, njenjete yaing'ono yobiriwira, njenjete yachikasu ya tiyi, nthata yaifupi ya tsitsi la tiyi, njenjete ya leaf burr, njenjete yakuda ya thorn ndi kachilomboka ka tea beauty elephant.
Iii. Njira Yogwiritsira Ntchito Bifenthrin
Pofuna kuletsa nthata zofiira za biringanya, ma mililita 30 mpaka 40 a 10% bifenthrin emulsifiable concentrate angagwiritsidwe ntchito pa mu, kusakaniza mofanana ndi ma kilogalamu 40 mpaka 60 a madzi ndikupopera. Zotsatira zake zimakhala pafupifupi masiku 10. Pa nthata yachikasu ya tiyi pa biringanya, ma mililita 30 a 10% bifenthrin emulsifiable concentrate angasakanizidwe mofanana ndi ma kilogalamu 40 a madzi kenako nkupopera kuti athetse.
2. Poyamba ntchentche zoyera zimapezeka mu ndiwo zamasamba, mavwende, ndi zina zotero, ma mililita 20-35 a 3% bifenthrin water emulsion kapena ma mililita 20-25 a 10% bifenthrin water emulsion angagwiritsidwe ntchito pa mu, osakanizidwa ndi makilogalamu 40-60 a madzi popopera.
3. Kwa tizilombo monga mphutsi, ziwala zobiriwira, mphutsi za tiyi ndi ntchentche zoyera zakuda pamitengo ya tiyi, yankho lochepetsedwa ka 1000-1500 likhoza kupopedwa kuti lithetsedwe panthawi yomwe mphutsi ndi nymphs zimachitika pa gawo lachiwiri mpaka lachitatu.
4. Pa nthawi yomwe tizilombo tating'onoting'ono ndi nymphs monga aphid, whiteflies ndi red spiders zimamera m'masamba a m'banja la cruciferous ndi cucurbitaceae, mankhwala ochepetsedwa madzi nthawi 1000-1500 akhoza kupopedwa kuti athetse vutoli.
5. Pofuna kuletsa tizilombo monga nthata za thonje ndi nthata za kangaude wofiira wa thonje, komanso odulira masamba a citrus, njira yothira madzi ochulukirapo ka 1000-1500 ikhoza kupopedwa pa zomera panthawi yothira mazira kapena nthawi yonse yothira mazira komanso nthawi yokhwima.
