Kugwiritsa ntchito
PermethrinIli ndi mphamvu yokhudza kwambiri komanso poizoni m'mimba, ndipo ili ndi mphamvu yolimba yotulutsa komanso imagwira ntchito mwachangu popha tizilombo. Ndi yokhazikika kwambiri ku kuwala, ndipo kukula kwa kukana tizilombo kumachepanso pansi pa mikhalidwe yomweyi yogwiritsidwa ntchito, ndipo ndi yothandiza kwambiri polimbana ndi mphutsi za lepidoptera. Itha kugwiritsidwa ntchito mu ndiwo zamasamba, tiyi, mitengo ya zipatso, thonje ndi mbewu zina kuti ipewe ndikulamulira rapeseed, aphid, thonje la bollworm, thonje la bollworm, thonje la aphid, green bug, yellow stripe beetle, pichesi small food worm, citrus leaf miner moth, 28 stars ladybird, tea inchworm, tea caterpillar, tea moth, nsabwe ndi tizilombo tina tomwe tili ndi thanzi labwino. Mwachitsanzo, kuwongolera thonje la bollworm ndi thonje la bollworm, mu nthawi yoberekera mazira, ndi 10% kirimu nthawi 1000 ~ 1250 nthawi yamadzimadzi, ndikuchiza bridge worm ndi leaf roll worm.
Kulamulira tizilombo towononga ukhondo
(1) Ntchentche zapakhomo: Mu malo okhala ntchentche zapakhomo, thirani kirimu wa 10% wa 0.01 ~ 0.03ml (chogwiritsira ntchito bwino 1 ~ 3mg) pa kiyubiki mita imodzi, zomwe zingaphe ntchentche bwino.
(2) Udzudzu: M'malo okhala udzudzu, thirani kirimu wa 10% 0.01 ~ 0.03ml (chogwiritsidwa ntchito bwino 1 ~ 3mg) pa kiyubiki mita imodzi. Pa mphutsi, kirimu wa 10% ukhoza kuchepetsedwa ndi madzi ndi 1mg/kg, kenako umathiridwa kapena kuthiridwa m'madzi omwe mphutsi zimaswanirana, zomwe zimatha kupha mphutsi bwino.
(3) Mapete: Gwiritsani ntchito mankhwala otsala pamwamba pa malo omwe mapete amagwirira ntchito, kapena thirani mwachindunji pa thupi la tizilombo, mlingo wake ndi 0.008g/m2.
(4) Chiswe: Pamwamba pa nsungwi ndi matabwa omwe ali pachiwopsezo cha nyerere ngati mankhwala otsala, kapena jambulani zisa za udzudzu, gwiritsani ntchito mafuta osungunuka 10% nthawi 830 ~ 1000 amadzimadzi, kuchuluka kogwira ntchito 100 ~ 120mg/kg.
Permethrin imagwiritsidwanso ntchito poletsa tizilombo tosungiramo zinthu (kuphatikizapo tizilombo tosungiramo tirigu), monga njenjete youma ya zipatso, kachilombo ka fodya, njenjete ya Indian grain, njenjete ya saw grain, njenjete ya red grain, njovu ya millet, njovu ya chimanga, njenjete ya tirigu, njenjete ya red grain robber, nthata ya coarse foot powder, quadripleura, ndi zina zotero. Kuletsa ndi kuwongolera dzimbiri la nsalu ya ubweya wa njenjete ndi kachilombo ka big fur, kachilombo ka black fur, kachilombo ka yellow foot, kachilombo ka njenjete ka mipando, njenjete ya bag grain, ndi zina zotero. Kupha chiswe cha m'nyumba ndi ma reticulitermes, ndikuletsa matabwa a nsungwi kuti asavulale ndi njenjete za m'nyumba za ku North America, nkhumba zobisa mipando, njenjete za brown powder, njenjete zazing'ono za nsungwi, ndi njenjete za bamboo za diso limodzi.
Njira zogwiritsira ntchito mankhwala ophera tizilombo
1. Kuwongolera tizilombo ta thonje: thonje la botolo mu nthawi yoberekera mazira, ndi kirimu wa 10% nthawi 1000-1250 kupopera madzi. Mlingo womwewo ukhoza kulamulira red bollworm, bridge worm ndi leaf roll worm. Nsabwe ya m'mera imatha kulamulidwa bwino pogwiritsa ntchito mafuta oyeretsera 10% nthawi 2000-4000 kupopera madzi panthawi yomwe imachitika. Mlingo uyenera kuwonjezeredwa kuti mupewe ndikuwongolera nsabwe.
2. Kuwongolera tizilombo tomwe timadya m'masamba: tizilombo ta kabichi, njenjete ya diamondi zaka zitatu isanathe kulamulira, ndi kirimu wa 10% wothira madzi nthawi 1000-2000. Ikhozanso kuchiza nsabwe za m'masamba.
3. Kuletsa tizilombo toyambitsa matenda m'mitengo ya zipatso: njenjete ya masamba a citrus potulutsa koyamba madzi ochulukirapo nthawi 1250-2500 kuposa kirimu wa 10%, ndipo imathanso kuchiza tizilombo ta lalanje ndi timbewu tina ta citrus, zomwe sizigwira ntchito motsutsana ndi nthata za citrus. Pamene kuchuluka kwa zipatso za dzira kunafika pa 1%, kuwongolera kunachitika ndi mafuta oyeretsera 10% nthawi 1000-2000 amadzimadzi owonjezera. Pa mlingo womwewo komanso nthawi yomweyo, imathanso kuwongolera nyongolotsi zazing'ono za chakudya cha peyala, komanso kuchiza njenjete yozungulira masamba ndi nsabwe za m'masamba ndi tizilombo tina ta mitengo ya zipatso, koma sizikhudza nthata za masamba.
4. Kuletsa tizilombo toyambitsa matenda mu mtengo wa tiyi: Kuletsa nyongolotsi za tiyi, njenjete za tiyi, mbozi za tiyi, njenjete za minga za tiyi, mu nthawi yophukira mphutsi 2-3, ndi kupopera madzi nthawi 2500-5000, komanso kuchiza mbozi wobiriwira, nsabwe za m'masamba.
5. Kuletsa tizilombo toyambitsa matenda ku fodya: tizilombo ta pichesi, tizilombo tobiriwira ku fodya pakapita nthawi yoti tipezeke ndi mankhwala opopera a 10-20mg/kg mofanana.
