Zotsatira ndi kugwiritsa ntchito Bifenthrin

Zanenedwa kutibifenthrinIli ndi zotsatira zoyipa zokhudzana ndi kukhudzana ndi m'mimba, ndipo imakhala ndi zotsatira zokhalitsa. Imatha kuletsa tizilombo tomwe timakhala pansi pa nthaka monga mphutsi, mphemvu, tizilombo ta singano zagolide, nsabwe za m'masamba, nyongolotsi za kabichi, ntchentche zoyera za m'nthaka, akangaude ofiira, nthata zachikasu za tiyi ndi tizilombo tina ta masamba ndi tiyi Tizilombo ta mitengo ya tiyi monga mphutsi ya tiyi, mbozi ya tiyi, njenjete yakuda ya tiyi, ndi zina zotero. Pakati pa izi, nsabwe za m'masamba, mbozi za kabichi, akangaude ofiira, ndi zina zotero zomwe zili pamasamba zimatha kuthetsedwa ndi kupopera madzi a bifenthrin nthawi 1000-1500.

1. Bifenthrin ili ndi poizoni wokhudza m'mimba, siigwira ntchito yotulutsa fumbi m'thupi, imagwetsa mwachangu, imagwira ntchito kwa nthawi yayitali, komanso imapha tizilombo tosiyanasiyana. Imagwiritsidwa ntchito makamaka polimbana ndi mphutsi za lepidopteran, Whiteflies, aphid, akangaude odya zomera ndi tizilombo tina.

1. Pewani ndi kulamulira tizilombo tomwe timawononga mavwende, mtedza ndi mbewu zina pansi pa nthaka, monga nkhuyu, zinkhanira, ndi tizilombo ta singano zagolide.

2. Pewani ndi kulamulira tizilombo towononga zomera monga nsabwe za m'masamba, njenjete ya diamondback, Spodoptera litura, nyongolotsi ya beet armyworm, mbozi ya kabichi, ntchentche yoyera ya greenhouse, kangaude wa biringanya, ndi nthata zachikasu.

3. Kupewa ndi kuwongolera tizilombo toyambitsa matenda a tiyi, mphutsi za tiyi, njenjete zakuda za tiyi, njenjete za tiyi, njenjete zazing'ono zobiriwira, thrips zachikasu za tiyi, nthata zazifupi za tiyi, njenjete ya ndulu ya masamba, nthata yoyera ya minga yakuda, tizilombo ta tiyi ndi tizilombo tina ta mitengo ya tiyi.

Tamagwiritsa ntchitobifenthrin

1. Pofuna kuletsa nthata zofiira mu biringanya, 30-40 ml ya 10% bifenthrin EC ingagwiritsidwe ntchito pa mu, yosakanizidwa ndi 40-60 kg ya madzi, kenako ipoperedwe mofanana. Nthawi yogwira ntchito ndi pafupifupi masiku 10; nthata zachikasu pa biringanya zitha kugwiritsidwa ntchito. Gwiritsani ntchito 30 ml ya 10% bifenthrin EC, onjezerani 40 kg ya madzi, sakanizani mofanana, kenako thirani kuti muchepetse.

2. Poyamba ntchentche zoyera monga ndiwo zamasamba ndi mavwende, 20-35 ml ya 3% bifenthrin water emulsion kapena 20-25 ml ya 10% bifenthrin water emulsion ingagwiritsidwe ntchito pa ekala iliyonse, yosakanizidwa ndi 40-60 kg ya madzi kuti mupewe komanso kuchiza.

3. Pa tizilombo ta mphutsi, tizilombo tating'onoting'ono tobiriwira, tizilombo ta tiyi, tizilombo toyera ta minga, ndi zina zotero pa mitengo ya tiyi, mankhwala opopera madzi okwana 1000-1500 angagwiritsidwe ntchito popewa ndi kuwongolera tizilombo toyambitsa matenda pa nthawi ya 2-3 ya ana aang'ono ndi a nymph.

4. Pa nthawi yomwe nsabwe za m'masamba, ntchentche zoyera, akangaude ofiira, ndi zina zotero zimapezeka pa ndiwo zamasamba monga cruciferous ndi cucurbits, mutha kugwiritsa ntchito kupopera madzi nthawi 1000-1500 kuti muchepetse.

5. Pofuna kuletsa thonje, akangaude a thonje ndi tizilombo tina, ofukula masamba a citrus ndi tizilombo tina, madziwo angagwiritsidwe ntchito kupopera zomera nthawi yokwana 1000-1500 panthawi yoswa mazira kapena nthawi yoswa komanso nthawi ya kukula.
