Flonicamidyog ib qho tshuaj tua kab pyridine amide (los yog nicotinamide) pom los ntawm Ishihara Sangyo Co., Ltd. ntawm Nyiv.Nws tuaj yeem tswj tau cov kab tho-nqus cov kab tsuag ntawm ntau cov qoob loo, thiab muaj txiaj ntsig zoo, tshwj xeeb tshaj yog rau aphids.Muaj txiaj ntsig.Nws cov txheej txheem ntawm kev txiav txim yog qhov tshiab, nws tsis muaj qhov cuam tshuam nrog lwm cov tshuaj tua kab tam sim no ntawm kev ua lag luam, thiab nws muaj toxicity tsawg rau muv.
Nws tuaj yeem nkag mus los ntawm cov hauv paus hniav mus rau stems thiab nplooj, tab sis kev nkag mus los ntawm nplooj mus rau stems thiab cov hauv paus hniav yog qhov tsis muaj zog.Tus neeg sawv cev ua haujlwm los ntawm kev cuam tshuam qhov nqus ntawm cov kab tsuag.Pests nres nqus sai sai tom qab noj cov tshuaj tua kab, thiab thaum kawg tuag ntawm kev tshaib kev nqhis.Raws li kev txheeb xyuas hluav taws xob ntawm tus cwj pwm nqus cov kab, tus neeg sawv cev no tuaj yeem ua rau lub qhov ncauj koob cov ntaub so ntswg nqus cov kab tsuag xws li aphids tsis tuaj yeem nkag mus rau hauv cov ntaub so ntswg thiab ua haujlwm zoo.
Lub mechanism ntawm kev txiav txim ntawm flonicamid thiab nws daim ntawv thov
Flonicamid muaj cov txheej txheem tshiab ntawm kev ua haujlwm, thiab muaj kev ua haujlwm zoo neurotoxicity thiab kev tiv thaiv sai sai tiv thaiv kab-nqus cov kab tsuag xws li aphids.Nws thaiv cov nyhuv ntawm aphid koob ua rau nws zoo ib yam li pymetrozine, tab sis nws tsis txhim khu kev sib cog lus ntawm lub foregut ntawm migratory locusts zoo li pymetrozine;Nws yog neurotoxic, tab sis yog lub hom phiaj ntawm cov paj hlwb Acetylcholinesterase thiab nicotinic acetylcholine receptors tsis muaj txiaj ntsig.Lub International Action Committee on Insecticide Resistance tau faib flonicamid nyob rau hauv Qeb 9C: Xaiv Homopteran Antifeedants, thiab nws yog tib tug tswv cuab ntawm pawg ntawm cov khoom no."Ib tug tswv cuab" txhais tau hais tias nws tsis muaj kev sib tw nrog lwm cov tshuaj tua kab.
Flonicamid yog xaiv, muaj zog, muaj zog osmotic nyhuv, thiab muaj cov nyhuv ntev.Nws tuaj yeem siv rau hauv cov txiv hmab txiv ntoo, cereals, qos yaj ywm, nplej, paj rwb, zaub, taum, dib, eggplants, melons, tshuaj yej ntoo thiab ornamental nroj tsuag, thiab lwm yam. Tswj kom nqus cov qhov ncauj kab tsuag, xws li aphids, whiteflies, xim av planthoppers, thrips thiab leafhoppers, thiab lwm yam, ntawm cov uas nws muaj tshwj xeeb los ntawm aphids.
Cov yam ntxwv ntawm Flonicamid:
1. Ntau hom kev ua.Nws muaj cov haujlwm ntawm kev sib cuag tua, plab lom thiab tshuaj tua kab mob.Nws feem ntau cuam tshuam qhov kev noj cov kua txiv hmab txiv ntoo los ntawm lub plab lom nyhuv, thiab qhov tshwm sim ntawm kev noj tshuaj tiv thaiv tshwm sim thiab kev tuag tshwm sim.
2. Zoo nkag mus thiab conductivity.Cov tshuaj ua kua muaj zog permeability hauv cov nroj tsuag, thiab tseem tuaj yeem nkag mus los ntawm cov hauv paus hniav mus rau stems thiab nplooj, uas muaj kev tiv thaiv zoo ntawm nplooj tshiab thiab cov ntaub so ntswg tshiab ntawm cov qoob loo, thiab tuaj yeem tswj cov kab tsuag hauv ntau qhov chaw ntawm cov qoob loo.
3. Kev pib sai thiab tswj kev phom sij.Cov kab tho-nqus cov kab tsuag tsis txhob nqus thiab pub rau hauv 0.5 mus rau 1 teev tom qab nqus cov kua txiv hmab txiv ntoo uas muaj flonicamid, thiab tsis muaj excrement tshwm sim tib lub sijhawm.
4. Lub sijhawm siv tau ntev.Cov kab tsuag pib tuag tom qab 2 mus rau 3 hnub tom qab txau, uas qhia tau hais tias cov nyhuv qeeb qeeb, tab sis cov nyhuv ntev mus txog 14 hnub, uas zoo dua li lwm cov khoom nicotinic.
5. Kev nyab xeeb zoo.Cov khoom no tsis cuam tshuam rau cov tsiaj hauv dej thiab cov nroj tsuag.Muaj kev nyab xeeb rau cov qoob loo ntawm cov koob tshuaj pom zoo, tsis muaj phytotoxicity.Nws yog tus phooj ywg zoo rau cov kab muaj txiaj ntsig thiab cov yeeb ncuab ntuj, thiab muaj kev nyab xeeb rau cov muv.Tshwj xeeb tshaj yog haum rau siv nyob rau hauv pollination greenhouses.
