Rice planthoppers muaj xws li BPH, Nilaparvata planthopper thiab Nilaparvata planthopper. Peb hom qoob loo cog qoob loo muaj cov tsos mob zoo ib yam, thiab cov neeg laus thiab cov nymphs tuaj yeem ua mob nplej. Lawv txhua tus siv lawv lub qhov ncauj nqus qhov ncauj txhawm rau txhawm rau stems, nplooj, thiab pob ntseg ntawm nplej thiab nqus cov kua txiv hmab txiv ntoo los ntawm cov nplej. Vim hais tias cov nroj tsuag cov as-ham raug noj, nws ncaj qha cuam tshuam rau kev loj hlob ntawm cov nroj tsuag. Los ntawm sab nraud, cov nplooj tig daj thiab xim av, qhov kev loj hlob yog inhibited, cov nroj tsuag yog nquag mus pw, lub taub hau thiab fruiting yog cuam tshuam, thiab tawm los yog ho txo.
Hnub no kuv yuav qhia koj txog ib qho chaw uas tuaj yeem tswj tau ntau yam qoob loo cog qoob loo-Triflumezopyrim. Nws yog cov tshuaj tua kab mob mesogenic pyrimidinone tshiab tsim los ntawm Corteva. Nws yog nicotinic acetylcholine receptor inhibitor thiab tuaj yeem tswj cov kab tsuag Lepidopteran thiab Homoptera zoo. Nws tuaj yeem tiv thaiv thiab tswj cov kab tsuag xws li nplej planthoppers thiab tiv thaiv kab mob kis los ntawm cov nplej cog qoob loo. Tam sim no nws tau dhau los ua tus qauv tshiab rau kev tswj cov qoob loo cog qoob loo.
Lub mechanism ntawm kev txiav txim thiab kev siv ntawm Triflumezopyrim
Triflumezopyrim ua rau nicotinic acetylcholine receptor (nAChR) ntawm cov kab, tab sis tsis zoo li feem ntau lwm cov tshuaj tua kab uas ua rau cov receptor no, nws inhibits es tsis ua kom nws, ua rau nws nicotinic acetylcholine receptor inhibitor. Tom qab kab mob lom, tus neeg yuav sluggish thiab motionless yam tsis muaj excitement los yog spasm, ces ua tuag tes tuag taw, tuag tes tuag taw, thiab thaum kawg tuag.
Lub International Insecticide Resistance Action Committee (IRAC) tau faib cov triflumezopyrim raws li Pawg 4E, tshuaj tua kab mesionic, uas tam sim no tsuas muaj ib qho active ingredient. Triflumezopyrim tsis muaj kev sib tw nrog lwm cov tshuaj tua kab hauv pawg (xws li cov tshuaj tua kab neonicotinoid) lossis sab nraum pawg. Yog li ntawd, triflumezopyrim tuaj yeem tsis tsuas yog tswj tau cov qoob loo cog qoob loo, tab sis kuj yog ib qho cuab yeej tseem ceeb rau kev tswj hwm kev tswj hwm lossis kev tswj hwm ntawm cov qoob loo cog qoob loo, teeb tsa cov qauv tshiab rau kev tiv thaiv thiab tswj cov qoob loo cog qoob loo. Cov txiaj ntsig ntawm kev sim tshuaj lom neeg hauv tsev qhia tau hais tias cov neeg cog qoob loo xim av los ntawm Nyab Laj, Thaib, Is Nrias teb thiab lwm lub tebchaws tiv taus imidacloprid, tab sis cov neeg tiv taus no tsis muaj qhov cuam tshuam rau triflumezopyrim. Txawm hais tias cov qoob loo cog qoob loo tsim cov kab mob metabolic rau ntau yam tshuaj tua kab, suav nrog neonicotinoids, Triflumezopyrim tseem tuaj yeem muab kev tswj xyuas zoo thiab kav ntev.
Triflumezopyrim feem ntau yog siv rau hauv nplej, tab sis kuj tseem siv tau rau cov qoob loo xws li paj rwb, pob kws thiab taum pauv. Triflumezopyrim muaj cov txheej txheem zoo ntawm kev ua haujlwm thiab permeability, thiab tiv taus dej nag. Nws tuaj yeem siv rau kev txau cov nplooj, hnav khaub ncaws hnav, grafting, thiab kho av. Cov kev sim teb tau lees paub tias nws tuaj yeem tswj tau ntau yam qoob loo cog qoob loo (xws li cov nroj tsuag xim av, grey planthopper, white-backed planthopper, thiab lwm yam), leafhoppers, thiab lwm yam, nrog rau kev ua tau zoo sai thiab ua haujlwm ntev. Tsis tas li ntawd, triflumezopyrim tuaj yeem txhawb kev loj hlob ntawm nplej thiab muaj txiaj ntsig zoo rau kev txhim kho kom zoo thiab nce cov qoob loo.
Triflumezopyrim tuaj yeem sib xyaw nrog ntau yam khoom xyaw. Nws suav nrog tsis tsuas yog tetrazoantraniliprole, chlorantraniliprole, cyantraniliprole, mebamectin benzoate, beflufenodiamide, methoxyfenozide, fenmethrin, fenfentrile, Insecticides xws li avermectin kuj tuaj yeem ua ke nrog cov tshuaj fungicides isothiastrobines, thiab lwm yam. lwm.

Nws tsis tsuas yog suav nrog cov tshuaj tua kab xws li tetrazopyrmid, chlorantraniliprole, cyantraniliprole, mebamectin benzoate, chlorantraniliprole, methoxyfenozide, fenmethrin, pyrofenfenil thiab abamectin, tab sis kuj tuaj yeem ua ke nrog cov fungicides isothiastrobind, thiab lwm yam. .
Cov ntsiab lus
Nplej yog ib qho khoom noj tseem ceeb, thiab cov nplej cog qoob loo yog ib qho kab mob loj tshaj plaws hauv kev tsim cov nplej. Lawv yog cov tawg, zais thiab rhuav tshem, thiab yog ib qho tseem ceeb txwv tsis pub cov qoob loo siab thiab ruaj khov. Raws li kev siv tshuaj tua kab ntev ntev thiab loj, cov qoob loo cog qoob loo tau tsim ntau qib ntawm kev tiv thaiv cov tshuaj tua kab xws li pymetrozine, thiamethoxam, imidacloprid, thiab nitenpyram.
Raws li thawj qhov kev lag luam mesogenic pyrimidinone tshuaj tua kab, triflumezopyrim tau teeb tsa tus qauv tshiab rau kev tswj cov qoob loo cog qoob loo vim nws cov txheej txheem tshiab ntawm kev ua, kev tswj kom zoo, thiab noj tsawg. Triflumezopyrim tuaj yeem tiv thaiv thiab tswj cov qoob loo cog qoob loo thiab ntau yam uas tiv taus cov tshuaj tua kab. Nws tseem tuaj yeem tiv thaiv ntau yam kab mob kis los ntawm cov qoob loo cog qoob loo thiab tsim nyog rau kev tswj hwm kev tiv thaiv thiab kev tiv thaiv kab tsuag.
Tam sim no, triflumezopyrim tseem nyob hauv lub sijhawm tiv thaiv patent. Raws li triflumezopyrim tau sau npe nyob rau hauv ntau lub teb chaws thiab cheeb tsam, thiab ntau cov khoom sib xyaw thiab cov khoom siv ib zaug tau txhawb nqa thiab siv, nws qhov kev lag luam loj yuav nthuav dav ntxiv.
