Mnzake wina wa mlimi anakambilana n’kunena kuti patsabola pali nthata zambirimbiri ndipo samadziwa kuti ndi mankhwala ati amene angagwire ntchito, choncho analimbikitsa.Bifenazate.Mlimiyo anagula mankhwalawo ali yekha, koma patatha mlungu umodzi, ananena kuti nsabwezi sizikulamulidwa ndipo zikuipiraipira.Izi ziyenera kukhala zosatheka, kotero adapempha wolima kuti atumize zithunzi za mankhwala ophera tizilombo kuti awone.Nzosadabwitsa kuti sizinagwire ntchito, choncho Bifenazate inagulidwa ngati Bifenthrin.Ndiye pali kusiyana kotaniBifenthrinndiBifenazate?

Bifenthrin ndi yabwino kwambiri pakuwongolera tizilombo

Bifenthrin ndi mankhwala opha tizilombo tosiyanasiyana, osati ongolimbana ndi nthata zokha, komanso motsutsana ndi nsabwe za m'masamba, thrips, planthoppers, mbozi za kabichi, ndi tizilombo tapansi panthaka.Imachita bwino m'malo osamva bwino.Komabe, m'madera ovuta kwambiri (madera ambiri a mitengo ya masamba ndi zipatso), zotsatira za Bifenthrin zimachepetsedwa kwambiri ndipo zingagwiritsidwe ntchito ngati mankhwala.Mwachitsanzo, kuti muchepetse nsabwe za m'masamba ndi thrips, gwiritsani ntchito Bifenthrin ndi Acetamiprid ndi Thiamethoxam;kuti muchepetse mbozi za kabichi, gwiritsani ntchito Bifenthrin ndi Chlorfnapy.Bifenazate panopa makamaka ntchito kupewa ndi kulamulira nthata pa ulimi ulimi, ndi mayendedwe ena sanafufuzidwe.

Onse amatha kuchiza nthata, koma zotsatira zake zimakhala zosiyana

Bifenthrin imakhala ndi mphamvu zina pa akangaude ofiira ndi oyera, makamaka pamene idayambitsidwa koyamba, zotsatira zake zinali zabwino kwambiri.Komabe, pogwiritsa ntchito kwambiri ulimi, zotsatira zake zikuipiraipira.Makamaka m'zaka zaposachedwa, Bifenthrin akadali ntchito kuwonjezera pa kulamulira akangaude pa tirigu, ndipo kwenikweni amathandiza m'madera ena.

Bifenazate ndi mankhwala ophera tizilombo omwe amapangidwa kuti azitha kuwononga nthata.Ndiwothandiza kwambiri polimbana ndi akangaude ofiira ndi oyera, makamaka akuluakulu, ndipo amatha kuchotsedwa mwamsanga mkati mwa maola 24.

Kusiyana kwa mtengo ndi kwakukulu

Kusiyana kwamitengo pakati pa Bifenazate ndi Bifenthrin kulinso kwakukulu.Bifenazate ili ndi mtengo wapamwamba kwambiri, pamene Bifenthrin ndi yotsika mtengo ndipo imagwiritsidwa ntchito kwambiri pazaulimi.

Kodi Bifenthrin angagwiritsidwe ntchito kupewa akangaude?

Pambuyo powerenga izi, abwenzi ena sangathe kufunsa, kodi Bifenthrin angagwiritsidwe ntchito kuteteza akangaude ofiira ndi oyera?Malangizo kwa aliyense pano ndikuti ndibwino kuti musagwiritse ntchito m'malo olima zipatso ndi ndiwo zamasamba!

Akangaude ofiira ndi oyera amalimbana kwambiri ndi Bifenthrin, ndipo chitetezo cha Bifenthrin ndichosauka kwambiri.Bifenthrin itha kugwiritsidwa ntchito ngati chothandizira polumikizana ndi mankhwala ophera tizilombo osiyanasiyana.Ngati mukufuna kupewa akangaude ofiira ndi oyera pamtengo wotsika kwambiri, mutha kusankha abamectin m'malo mwake.

Chifukwa chiyani alimi ena sangathe kusiyanitsa mankhwala ophera tizilombo awiriwa?Chifukwa mayina awo amafanana, muyenera kutchula mayina awo momveka bwino pogula mankhwala, apo ayi mankhwala omwe mwapatsidwa ndi malo ogulitsa zaulimi sangakhale omwe mukufuna.

Zogulitsa ziwiri zotsatirazi zimayambitsidwa motsatana:

Bifenthrin

Bifenthrin ndi mankhwala a pyrethroid ndi acaricide omwe amapha tizilombo mwachangu.Tizilomboti timayamba kufa pasanathe ola limodzi kuchokera pamene tagwiritsa ntchito.Limakhala ndi zinthu zitatu izi:

1. Ndioyenera kudzala mbewu zosiyanasiyana ndipo amapha tizilombo tambiri.Bifenthrin angagwiritsidwe ntchito pa tirigu, balere, maapulo, zipatso, mphesa, nthochi, biringanya, tomato, tsabola, mavwende, kabichi, anyezi wobiriwira, thonje ndi mbewu zina.

Matenda omwe angathane nawo akuphatikizapo akangaude, nsabwe za m'masamba, mbozi za kabichi, njenjete za diamondback, pichesi heartworms, whiteflies, tiyi mbozi ndi tizilombo tina, tokhala ndi tizilombo tosiyanasiyana.

2. Iphani tizilombo mwachangu ndikukhala kwa nthawi yayitali.Bifenthrin ali ndi kukhudzana ndi gastrotoxic zotsatira.Ndi chifukwa cha kuphana kwake komwe tizilombo timayamba kufa ola la 1 pambuyo pogwiritsira ntchito, ndipo chiwerengero cha imfa ya tizilombo ndi 98.5% mkati mwa maola 4, ndipo chimapha mazira, mphutsi, ndi nthata zazikulu;Komanso, Bifenthrin ali ndi zotsatira mpaka 10 - pafupifupi 15 masiku.

3. Kupha tizilombo toyambitsa matenda.Ntchito yophera tizilombo ya Bifenthrin ndiyokwera kuposa ma pyrethroid agents, ndipo mphamvu yowongolera tizilombo ndiyabwinoko.Akagwiritsidwa ntchito pa mbewu, amatha kulowa mumbewu ndikuyenda kuchokera pamwamba mpaka pansi pamene madzi akuyenda mkati mwa mbewu.Tizilombo tikawononga mbewu, madzi a Bifenthrin mu mbewu amawononga tizirombo.
4. Mankhwala ophatikiza.Ngakhale kuti mlingo umodzi wa Bifenthrin uli ndi zotsatira zabwino kwambiri zowononga tizilombo, tizirombo tina timayamba kukana pamene nthawi ndi nthawi yogwiritsira ntchito ikuwonjezeka.Chifukwa chake, zitha kusakanikirana moyenera ndi othandizira ena kuti mukwaniritse bwino zowononga tizirombo:Bifenthrin+Thiamethoxam, Bifenthrin+Chlorfenapyr,Bifenthrin+Lufenuron, Bifenthrin+Dinotefuran, Bifenthrin+Imidaclorprid, Bifenthrin+Acetamiprid, ndi zina.

5. Zinthu zofunika kuzindikila.
(1) Samalani ndi kukana mankhwala.Bifenthrin, chifukwa alibe machitidwe, sangathe kulowa mwachangu mbali zonse za mbewu.Chifukwa chake, popopera mbewu mankhwalawa, iyenera kupakidwa mofanana.Pofuna kupewa tizirombo kuti tiyambe kukana mankhwala ophera tizilombo, Bifenthrin amagwiritsidwa ntchito limodzi ndi mankhwala ena ophera tizilombo, monga Thiamethoxam., Imidacloprid ndi mankhwala ena ophera tizilombo adzakhala othandiza kwambiri.
(2) Samalani ndi malo ogwiritsira ntchito.Bifenthrin ndi poizoni ku njuchi, nsomba ndi zamoyo zina zam'madzi, ndi nyongolotsi za silika.Mukamagwiritsa ntchito, muyenera kupewa malo pafupi ndi njuchi, mbewu zamaluwa zamaluwa, nyumba za silika ndi minda ya mabulosi.

Bifenazate

Bifenazate ndi mtundu watsopano wa foliar acaricide wosankha womwe suli wadongosolo ndipo umagwiritsidwa ntchito kwambiri poletsa akangaude, koma umapha dzira pa nthata zina, makamaka akangaude a mawanga awiri.Chifukwa chake, Bifenazate pakadali pano ndi imodzi mwama acaricides abwino opha akangaude okhala ndi mawanga awiri.Panthawi imodzimodziyo, chifukwa ndi otetezeka kwa njuchi ndipo sizikhudza kumasulidwa kwa njuchi m'madera a sitiroberi, Bifenazate imagwiritsidwanso ntchito kwambiri m'madera obzala sitiroberi.Zotsatirazi zikuyang'ana pa kuyambitsa makina ndi makhalidwe a Bifenazate.

Njira ya Bifenazate's acaricidal action ndi gamma-aminobutyric acid (GABA) receptor yomwe imagwira ntchito pamayendedwe a nthata.Imagwira ntchito pakukula kwa nthata, imakhala ndi zochitika za ovicide ndi kugwetsa nsabwe zazikulu, ndipo imakhala ndi nthawi yofulumira kwambiri.Imfa ya nthata imatha kuwonedwa patatha maola 36-48 mutatha kugwiritsa ntchito.

Nthawi yomweyo, Bifenazate imakhala ndi nthawi yayitali ndipo imatha masiku 20-25.Bifenazate imakhala ndi zotsatira zochepa pa nthata zolusa ndipo ilibe mphamvu pakukula kwa mbewu.Chifukwa Bifenazate samakhudzidwa ndi kutentha, zotsatira zake pa nthata ndizokhazikika.Kuphatikiza apo, ndizotetezeka kwambiri kwa njuchi ndi adani achilengedwe a nthata zolusa komanso zachilengedwe.

Bifenazate imayang'anira zolinga zosiyanasiyana, kuphatikizapo: akangaude a mawanga awiri, akangaude a uchi, akangaude a maapulo, akangaude a citrus, nsabwe za m'mphepete mwa nyanja, ndi nthata za spruce claw.Zosagwira ntchito motsutsana ndi nthata za dzimbiri, nsabwe za m'masamba, nthata zazikulu, ndi zina.

Mankhwala ophatikiza:Bifenazate+ Etoxazole;Bifenazate+Spirodiclofen; Bifenazate+Pyridaben.

Kusamalitsa:

(1) Bifenazate imakhala ndi mphamvu yopha dzira, koma iyenera kugwiritsidwa ntchito pamene malo a tizilombo ali ochepa (kumayambiriro kwa nyengo yakukula).Malo a tizilombo akachuluka, amafunika kusakanizidwa ndi opha nkhono.

(2) Bifenazate ilibe machitidwe.Kuonetsetsa kuti ntchitoyo ikugwira ntchito bwino, popopera mbewu mankhwalawa, onetsetsani kuti mbali zonse za masamba ndi pamwamba pa chipatso zimapopera mofanana.

(3) Bifenazate tikulimbikitsidwa kuti ntchito pa intervals wa masiku 20, ndi ntchito kwa 4 pa chaka mbewu iliyonse, ndi ntchito alternately ndi ma acaricides ndi njira zina zochita.
