Flonicamidndi mankhwala ophera tizirombo a pyridine amide (kapena nicotinamide) opezeka ndi Ishihara Sangyo Co., Ltd. waku Japan.Imatha kuthana ndi tizirombo tobaya zoboola pambewu zosiyanasiyana, ndipo imalowetsa bwino, makamaka nsabwe za m'masamba.Kuchita bwino.Limagwirira ake zochita ndi buku, alibe mtanda kukana ndi mankhwala ena ophera pakali pano pa msika, ndipo ali otsika kawopsedwe njuchi.
Ikhoza kulowa kuchokera ku mizu kupita ku tsinde ndi masamba, koma kulowa kuchokera ku masamba kupita ku tsinde ndi mizu ndi yofooka.Wothandizira amagwira ntchito polepheretsa kuyamwa kwa tizilombo.Tizilombo timasiya kuyamwa titangomwa mankhwala ophera tizilombo, ndipo pamapeto pake timafa ndi njala.Malinga ndi kusanthula kwamagetsi kwa khalidwe la tizilombo toyamwa, wothandizira uyu amatha kupanga minofu yapakamwa ya singano ya tizirombo toyamwa monga nsabwe za m'masamba zomwe sizingathe kulowetsa muzomera ndikukhala ogwira mtima.
Limagwirira ntchito ya flonicamid ndi ntchito yake
Flonicamid ili ndi njira yatsopano yochitirapo kanthu, ndipo ili ndi neurotoxicity yabwino komanso ntchito yoletsa kudya mwachangu motsutsana ndi tizirombo tobaya monga nsabwe za m'masamba.Kutsekereza kwake pa singano za aphid kumapangitsa kukhala kofanana ndi pymetrozine, koma sikumawonjezera kukomoka kwadzidzidzi kwa dzombe losamuka ngati pymetrozine;ndi neurotoxic, koma ndi chandamale cha minyewa ya Acetylcholinesterase ndi nicotinic acetylcholine receptors alibe mphamvu.International Action Committee on Insecticide Resistance yayika flonicamid mu Gulu 9C: Selective Homopteran Antifeedants, ndipo ndi membala yekhayo wa gulu ili lazinthu."Membala yekhayo" amatanthauza kuti alibe kutsutsana ndi mankhwala ena ophera tizilombo.
Flonicamid ndiyosankha, mwadongosolo, imakhala ndi mphamvu ya osmotic, ndipo imakhala ndi nthawi yayitali.Itha kugwiritsidwa ntchito mumitengo ya zipatso, chimanga, mbatata, mpunga, thonje, ndiwo zamasamba, nyemba, nkhaka, biringanya, mavwende, mitengo ya tiyi ndi zomera zokongoletsera, etc. leafhoppers, etc., amene ali wapadera zotsatira pa nsabwe za m'masamba.
Zotsatira za Flonicamid:
1. Njira zosiyanasiyana.Lili ndi ntchito zopha anthu, kupha m'mimba komanso kuletsa kuyamwitsa.Iwo makamaka amalepheretsa yachibadwa kudya kuyamwa ndi m`mimba poizoni tingati, ndi chodabwitsa cha antifeeding zimachitika ndi imfa.
2. Kulowa bwino ndi kuwongolera.Mankhwala amadzimadzi ali ndi mphamvu zowonongeka muzomera, ndipo amathanso kulowa kuchokera ku mizu kupita ku tsinde ndi masamba, omwe ali ndi chitetezo chabwino pa masamba atsopano ndi zatsopano za mbewu, ndipo amatha kuthetsa tizirombo m'madera osiyanasiyana a mbewu.
3. Kuyamba mwachangu ndikuwongolera zoopsa.Tizilombo tobaya timasiya kuyamwa ndi kudyetsa pakatha ola 0,5 mpaka 1 mutakoka kuyamwa kwa mmera wokhala ndi flonicamid, ndipo chimbudzi sichidzawonekera nthawi yomweyo.
4. Nthawi yovomerezeka ndi yayitali.Tizilombo tinayamba kufa 2 mpaka 3 patatha kupopera mbewu mankhwalawa, kuwonetsa pang'onopang'ono kuchitapo kanthu mwachangu, koma zotsatira zake zinali mpaka masiku 14, zomwe zinali zabwino kuposa zinthu zina za nicotinic.
5. Chitetezo chabwino.Mankhwalawa alibe mphamvu pa nyama zam'madzi ndi zomera.Zotetezedwa ku mbewu pamilingo yovomerezeka, palibe phytotoxicity.Ndiwochezeka kwa tizilombo topindulitsa ndi adani achilengedwe, komanso otetezeka kwa njuchi.Makamaka abwino ntchito pollination greenhouses.
