Spinosad CAS Yabwino Kwambiri 131929-60-7 Yotumiza Mwachangu

Mafotokozedwe Akatundu

Spinosad ndi poizoni wochepa, wothandiza kwambiri,Fungicide ya BroadspectrumNdipo yakhala ikugwiritsidwa ntchito padziko lonse lapansi pakulamulira tizilombo tosiyanasiyana, kuphatikizapo Lepidoptera, Diptera, Thysanoptera, Coleoptera, Orthoptera ndi Hymenoptera, ndi ena ambiri. Spinosad imaonedwanso ngati chinthu chachilengedwe, kotero imavomerezedwa kuti igwiritsidwe ntchito muulimi wachilengedwe ndi mayiko ambiri.

Kugwiritsa Ntchito Njira

1. Za masambakuletsa tizilomboya diamondback moth, gwiritsani ntchito 2.5% suspension agent nthawi 1000-1500 ya yankho kuti mupopere mofanana pa siteji yayikulu ya mphutsi zazing'ono, kapena gwiritsani ntchito 2.5% suspension agent 33-50ml mpaka 20-50kg ya madzi opopera 667m iliyonse.².

2. Kuti muchepetse nyongolotsi ya beet armyworm, thirani madzi ndi 2.5% suspension agent 50-100ml iliyonse 667 square meters kumayambiriro kwa mphutsi, ndipo zotsatira zabwino kwambiri zimakhala madzulo.

3. Pofuna kupewa ndi kulamulira tizilombo toyambitsa matenda a thrips, pa malo aliwonse okwana masikweya mita 667, gwiritsani ntchito mankhwala odulira 2.5% 33-50ml kupopera madzi, kapena gwiritsani ntchito mankhwala odulira 2.5% kupopera madzi nthawi 1000-1500, popopera mofanana, poyang'ana minofu yaing'ono monga maluwa, zipatso zazing'ono, nsonga ndi mphukira.

Kusamala

1. Zingakhale zoopsa kwa nsomba kapena zamoyo zina zam'madzi, ndipo kuipitsa madzi ndi maiwe kuyenera kupewedwa.

2. Sungani mankhwala pamalo ozizira komanso ouma.

3. Nthawi pakati pa kupopera komaliza ndi kukolola ndi masiku 7. Pewani kukumana ndi mvula mkati mwa maola 24 mutapopera.

4. Samalani ndi chitetezo cha munthu payekha. Ngati chalowa m'maso, tsukani nthawi yomweyo ndi madzi ambiri. Ngati chakhudzana ndi khungu kapena zovala, tsukani ndi madzi ambiri kapena sopo. Ngati mwachita molakwika, musamadzisanzire nokha, musadyetse chilichonse kapena kusanza odwala omwe sali maso kapena omwe ali ndi kutupa kwa minofu. Wodwalayo ayenera kutumizidwa kuchipatala nthawi yomweyo kuti akalandire chithandizo.

Njira yochitira zinthu

Kagwiridwe ka ntchito ka polycidin ndi katsopano komanso kosiyana, komwe ndi kosiyana ndi ma macrolides wamba, ndipo kapangidwe kake ka mankhwala kamene kamatsimikizira njira yake yapadera yophera tizilombo. Polycidin imakhudza mwachangu ndi kumeza tizilombo. Ili ndi zizindikiro zapadera za poizoni wa mitsempha. Kagwiridwe kake ka ntchito ndikulimbikitsa dongosolo la mitsempha la tizilombo, kuwonjezera ntchito yake yodziyimira payokha, ndikupangitsa kuti minofu isagwire ntchito, kulephera, limodzi ndi kugwedezeka ndi kufooka. Zinawonetsedwa kuti nicotinic acetylcholine receptor (nChR) imayendetsedwa nthawi zonse kuti ipangitse acetylcholine (Ach) kutulutsidwa kwa nthawi yayitali. Polycidin imagwiranso ntchito pa ma receptor a γ-aminobutyric acid (GAGB), kusintha ntchito ya njira za GABA zotetezedwa ndi chlorine ndikuwonjezera ntchito yake yophera tizilombo.

Njira yowononga

Zotsalira za mankhwala ophera tizilombo m'chilengedwe zimatanthauza "kulemera kwakukulu" kwa mankhwala ophera tizilombo omwe chilengedwe chingakhale nawo, kutanthauza, m'dera linalake komanso nthawi inayake, zonse ziwiri kuti zitsimikizire ubwino wa zamoyo ndi zokolola za ulimi komanso kuti zisawononge ubwino wa chilengedwe. "Kulemera kwakukulu" ndi mtengo woyerekeza poyesa chitetezo cha chilengedwe cha mankhwala ophera tizilombo, ndipo ndi chosinthika chomwe chimachepa pang'onopang'ono ndi kusintha kwa nthawi ndi mikhalidwe ya chilengedwe. Bola ngati sichidutsa malire awa, chitetezo cha chilengedwe cha mankhwala ophera tizilombo chimayesedwa. Polycidin imawonongeka mofulumira m'chilengedwe kudzera m'njira zosiyanasiyana zosakanikirana, makamaka kuwonongeka kwa kuwala ndi kuwonongeka kwa tizilombo toyambitsa matenda, ndipo pamapeto pake imawola kukhala zinthu zachilengedwe monga kaboni, haidrojeni, mpweya, ndi nayitrogeni, motero sizimayambitsa kuipitsa chilengedwe. Hafu ya moyo wa kuwala kwa kuwala kwa kuwala kwa kuwala kwa dzuwa kwa polycidin m'nthaka inali masiku 9 mpaka 10, ya pamwamba pa tsamba inali masiku 1.6 mpaka 16, ndipo ya madzi inali yochepera tsiku limodzi. Zachidziwikire, theka la moyo limakhudzana ndi mphamvu ya kuwala, ngati palibe kuwala, theka la moyo wa multicidin ndi kagayidwe ka nthaka ya aerobic ndi masiku 9 mpaka 17. Kuphatikiza apo, kuchuluka kwa polycidin komwe kumasamutsa nthaka ndi K yapakati (5 ~ 323), kusungunuka kwake m'madzi kumakhala kochepa kwambiri ndipo kumatha kuwonongeka mwachangu, kotero mphamvu ya leaching ya polycidin ndi yotsika kwambiri, kotero ingagwiritsidwe ntchito moyenera, komanso ndi yotetezeka ku magwero amadzi apansi panthaka.
