High Qaulity Insecticide Methoprene 95%TC yokhala ndi Mtengo Wabwino Kwambiri
Mafotokozedwe Akatundu
Ndi biochemical insecticide wa insect juvenile hormone class.Tizilombo tating'onoting'ono timadzi tating'onoting'ono titha kuwongolera kakulidwe kake, kakulidwe, ndi kachitidwe kake.Ntchito yayikulu ya timadzi tating'onoting'ono ndikuletsa kusinthika kwa mphutsi zazing'ono, kukhalabe ndi mawonekedwe a siteji yaunyamata, ndikukhalabe mphutsi pambuyo posungunula.
Methoprene, monga zoteteza masamba a fodya, zimasokoneza njira yowotcha ya tizilombo.Zingathe kusokoneza kakulidwe ndi kakulidwe ka mbozi za fodya ndi fodya, zomwe zimapangitsa kuti tizilombo tating'onoting'ono tisakhale ndi mphamvu zobereka, potero zimayendetsa bwino kukula kwa tizilombo tosungira masamba a fodya.
Kugwiritsa ntchito
Tizilombo tating'onoting'ono timatha kupha tizilombo, timangofa panthawi ya kusintha kwa thupi, kapena kuchepetsa kuchuluka kwa ana chifukwa cha kusabereka kapena kuswa mazira.Chifukwa chake, zotsatira zake zimachedwa ndipo sangathe kuwongolera mwachangu kuvulaza kwa tizirombo tophulika, ndikuchepetsa kugwiritsa ntchito kwawo paulimi.Masiku ano, amagwiritsidwa ntchito kwambiri pazinthu zotsatirazi:
1. Kupewa ndi kuletsa tizirombo taumoyo.Fenpropathrin imakhala ndi zochita zambiri motsutsana ndi mphemvu zaku Germany ndipo zimatha kuyambitsa kusabereka mwa akulu akulu achikazi ndi amuna.Kuchiza mosalekeza ndi mankhwalawa kumatha kutha chifukwa cha kusabereka pakatha miyezi isanu ndi umodzi mpaka chaka, komanso kumagwira ntchito motsutsana ndi mphemvu zazikulu.Kupanga methoprene yotulutsa mosalekeza kumathandizanso kupewa komanso kuchiza utitiri, udzudzu, ndi ntchentche.
2. Thirani tizirombo ta Hemiptera.Fenvalerate imagwira ntchito poletsa nsabwe za m'masamba ndi whiteflies ndipo idalembetsedwa ku United States.Koma kukhazikika sikwabwino kukagwiritsidwa ntchito m'munda.Dioxycarb ndi yothandiza polamulira greenhouse whiteflies ndi crustaceans.
3. Kupewa ndi kuletsa tizirombo tosungirako.Hormoni yachinyamata imakhala ndi zochita zambiri motsutsana ndi tizirombo ta Lepidoptera panthawi yosungidwa, monga tirigu, ufa, ndi fodya.Ku United States, yayesedwa kuti ikhale yothandiza polimbana ndi tizirombo tambiri tosungirako, monga fenpropathrin ndi carbendazim.
4. Kuteteza ndi kulamulira nyerere.Nyambo ya Fenpropathrin imatha kulepheretsa kusinthika kwa mphutsi zovulaza, kupangitsa nyerere kukhala mbewa, ndikuwongolera bwino nyerere zakukhitchini.Palinso malipoti ogwiritsira ntchito mahomoni achichepere pochiza chiswe.
5. Kuchulukitsa kupanga silika.Kupopera mbewu mankhwalawa timadzi ta ana kapena pseudojuvenile hormone monga anti juvenile hormone pampando wa silkworm (2-4 micrograms/mutu) kapena pa 5th instar silkworm body (1-3 micrograms/mutu) kungalepheretse kusinthika, kutalikitsa 5th instar larval stage by more kuposa tsiku limodzi, onjezerani chakudya, onjezerani kukula kwa munthu payekha, ndikuwonjezera kupanga silika.Nthawi zambiri, imatha kuchulukitsa zikwa 10000 ndi 15%.
Kugwiritsa Ntchito Njira
1. Sungani masamba a fodya kuti mupewe zikumbu.Uza 41% ufa wosungunuka 40000 nthawi zamadzimadzi pamasamba a fodya.Kuti muwonetsetse kuti masamba afodya atsitsidwa ndi kufalikira kwathunthu, mutha kugwiritsa ntchito makina opopera mochulukira kapena zida zapadera zotsitsira kwambiri zotsika kwambiri.
2. Kukhudzidwa kwa tizilombo ndi mahomoni achichepere kumasiyanasiyana pazigawo zosiyanasiyana za kukula ndi kakulidwe.Mphutsi kapena nymph ndizovuta kwambiri kumapeto, pamene magawo ena samva kwambiri.M'kati mwa kukula kwa tizilombo ndi chitukuko, nthawi yoyenera imasankhidwa ndipo mahomoni achichepere a exogenous amagwiritsidwa ntchito kuti asokoneze momwe timadzi timene timakhalira m'thupi la tizilombo toyambitsa matenda, kuchititsa kusintha kwachilendo, kusabereka kwa akuluakulu, kapena kulephera kuswa mazira, motero kukwaniritsa cholinga cholamulira ndi kuchotsa tizirombo.
3. IC50 fenvalerate ya Culex pipiens larvae ndi 0.48 micrograms pa lita, ndipo ID50 fenvalerate ya sera moth pupae ndi 2.2 micrograms pa pupa.
