Txawm hais tias cov nroj tsuag parasitic nematodes yog cov kab mob nematode, lawv tsis yog cov kab tsuag nroj tsuag, tab sis cov kab mob nroj tsuag.

Cog nematode kab mob hais txog ib hom nematode uas tuaj yeem ua rau ntau yam ntaub so ntswg ntawm cov nroj tsuag, ua rau cov nroj tsuag stunting, thiab kis lwm cov kab mob nroj tsuag thaum kis tus tswv tsev, ua rau cov tsos mob ntawm cov nroj tsuag.Cov nroj tsuag cab kab mob uas tau pom los txog tam sim no suav nrog hauv paus-knot nematodes, ntoo thuv ntoo nematodes, soybean cyst nematodes thiab qia nematodes, forerunner nematodes thiab lwm yam.

Siv cov hauv paus-knot nematode ua piv txwv:

Hauv paus-knot nematodes yog ib chav kawm tseem ceeb ntawm cov nroj tsuag pathogenic nematodes uas tau muab faib thoob plaws ntiaj teb.Hauv thaj chaw sov thiab subtropical uas muaj dej nag ntau thiab kev nyab xeeb me me, qhov teeb meem ntawm cov hauv paus-knot nematode yog qhov tshwj xeeb.

Txij li feem ntau cov kab mob nematode tshwm sim ntawm cov hauv paus hniav ntawm cov nroj tsuag, nws yog ib qho nyuaj rau siv tshuaj tua kab.Thiab nws yog qhov yooj yim heev rau ntau tiam neeg los sib tshooj hauv cov zaub ntsuab, uas tshwm sim tiag tiag, yog li cov hauv paus-knot nematodes feem ntau nyuaj rau tswj.

Hauv paus-knot nematode muaj ntau hom tswv, thiab tuaj yeem ua rau ntau tshaj 3000 hom tswv tsev xws li zaub, qoob loo zaub mov, qoob loo nyiaj ntsuab, ntoo txiv hmab txiv ntoo, ornamental nroj tsuag thiab nroj tsuag.Tom qab cov zaub muaj kab mob hauv paus-knot nematode, cov nroj tsuag saum toj no hauv av luv luv, cov ceg thiab nplooj yog shrunk los yog yellowed, kev loj hlob yog stunted, nplooj xim yog sib dua li yog tsis muaj dej, kev loj hlob ntawm cov nroj tsuag mob hnyav yog. qaug zog, cov nroj tsuag yog wilting nyob rau hauv drought, thiab tag nrho cov nroj tsuag tuag nyob rau hauv mob hnyav.

Cov tshuaj nematicides tuaj yeem muab faib ua fumigants thiab tsis fumigants raws li kev siv sib txawv.

Fumigant

Nws suav nrog halogenated hydrocarbons thiab isothiocyanates, thiab cov tsis fumigants suav nrog cov organic phosphorus thiab carbamate.Methyl bromide thiab chloropicrin yog halogenated hydrocarbons, uas tuaj yeem cuam tshuam cov protein synthesis ntawm cov hauv paus pob txha nematodes thiab cov tshuaj biochemical hauv cov txheej txheem ua pa;Carbosulfan thiab Mianlong belongs rau methyl isothiocyanate fumigants, uas tuaj yeem cuam tshuam kev ua pa ntawm cov hauv paus pob txha nematodes kom tuag.

Hom tsis fumigation

Ntawm cov tsis fumigant nematicides, thiazolphos, phoxim, phoxim thiabtshuaj chlorpyrifosbelongs rau cov organic phosphorus, carbofuran, aldicarb thiab carbofuran yog carbamate.Non fumigant nematicides rhuav tshem lub paj hlwb kev ua haujlwm ntawm cov hauv paus pob txha nematodes los ntawm kev khi rau acetylcholinesterase hauv cov synapses ntawm cov hauv paus pob txha nematodes.Lawv feem ntau tsis tua cov hauv paus pob txha nematodes, tab sis tsuas yog tuaj yeem ua rau cov hauv paus pob txha nematodes poob peev xwm los nrhiav tus tswv tsev thiab kis tau, yog li lawv feem ntau hu ua "nematode paralysis agents".

Tam sim no, tsis muaj ntau cov nematicides tshiab, ntawm cov fluorenyl sulfone, spiroethyl ester, bifluorosulfone thiab fluconazole yog cov thawj coj.Abamectinthiab thiazolophos kuj nquag siv.Tsis tas li ntawd, hais txog cov tshuaj tua kab mob lom, Penicillium lilacinus thiab Bacillus thuringiensis HAN055 rau npe hauv Konuo kuj muaj peev xwm ua lag luam muaj zog.
