Bifenthrinali ndi kukhudza kupha ndi zotsatira za poizoni m'mimba, ndi zotsatira zokhalitsa. Imatha kuwononga tizirombo tokhala pansi panthaka monga nyongolotsi, nyongolotsi, nyongolotsi, tizirombo ta masamba monga nsabwe za m’masamba, nyongolotsi za kabichi, ntchentche zobiriwira, akangaude ofiira, ndi nthata za tiyi, komanso tizirombo ta tiyi monga nyongolotsi za tiyi, mbozi za tiyi, ndi njenjete zakuda tiyi. Pakati pawo, nsabwe za m'masamba, nyongolotsi za kabichi, akangaude ofiira ndi tizirombo tina pamasamba zitha kuwongoleredwa ndi kupopera mbewu mankhwalawa nthawi 1000 mpaka 1500 kuchepetsedwa yankho la bifenthrin.
I. Ntchito yabifenthrin
Bifenthrin imakhala ndi kupha komanso kupha poizoni m'mimba, palibe zochita zamtundu uliwonse kapena zofukiza, kuthamanga kwapang'onopang'ono, zotsatira zokhalitsa, komanso mitundu ingapo ya mankhwala ophera tizilombo. Amagwiritsidwa ntchito kwambiri polimbana ndi mphutsi za lepidoptera, whiteflies, nsabwe za m'masamba, akangaude a herbivorous ndi tizirombo tina.
Ii. Ntchito zabifenthrin
1. Chepetsani tizirombo toyambitsa matenda m'nthaka monga mavwende ndi mtedza, monga magrubs,nyongolotsi, ndi wireworms.
2. Chepetsani tizirombo ta masamba monga nsabwe za m'masamba, njenjete za diamondback, nyongolotsi za diamondback armyworms, nyongolotsi za beet armyworms, nyongolotsi za kabichi, nyongolotsi zobiriwira, akangaude ofiira a biringanya ndi nthata za tiyi.
3. Chepetsani tizirombo ta tiyi, mbozi ya tiyi, njenjete ya tiyi yakuda, njenjete ya minga ya tiyi, tiyi tating'onoting'ono tobiriwira, tiyi wachikasu wa tiyi, njenjete za tsitsi lalifupi, njenjete za leaf burr moth, whitefly yamnga yakuda ndi kachilomboka.
Iii. Njira yogwiritsira ntchito bifenthrin
Pofuna kuthana ndi biringanya zofiira za akangaude, mamililita 30 mpaka 40 a 10% bifenthrin emulsifiable concentrate angagwiritsidwe ntchito pa mu, kusakaniza mofanana ndi 40 mpaka 60 kilogalamu ya madzi ndikupopera. Zotsatira zokhalitsa zimakhala pafupifupi masiku 10. Pa tiyi yellow mite pa biringanya, mamililita 30 a 10% bifenthrin emulsifiable concentrate akhoza kusakaniza wogawana ndi 40 kilogalamu ya madzi ndiyeno sprayed kulamulira.
2. Pa nthawi yoyamba ya whiteflyes zimachitika masamba, mavwende, etc., 20-35 milliliters 3% bifenthrin madzi emulsion kapena 20-25 milliliters 10% bifenthrin madzi emulsion angagwiritsidwe ntchito pa mu, wothira 40-60 makilogalamu madzi kulamulira kupopera mbewu mankhwalawa.
3. Kwa tizirombo monga inchiworms, green leafhoppers, mbozi za tiyi ndi ntchentche zoyera zakuda pamitengo ya tiyi, 1000-1500 times diluted solution ikhoza kupopera kuti alamulire panthawi yomwe mphutsi ndi nymphs zimachitika pa 2nd mpaka 3 instar stage.
4. Panthawi yakukula kwa akuluakulu ndi nymphs monga nsabwe za m'masamba, whiteflies ndi akangaude ofiira pamasamba a mabanja a cruciferous ndi cucurbitaceae, yankho la 1000-1500 losungunuka likhoza kupopera kuti liwongolere.
5. Pofuna kuthana ndi tizirombo monga nthata za thonje ndi akangaude ofiira a thonje, komanso ocheka masamba a citrus, yankho losungunuka la 1000-1500 nthawi lingathe kupopera pa zomera pa nthawi ya dzira kapena nthawi yoyamwitsa ndi wamkulu.
