Nubwo ibimera bya parasitike nematode ari ibyangiza nematode, ntabwo ari udukoko twangiza, ahubwo ni indwara ziterwa.

Indwara ya nematode yerekana ubwoko bwa nematode ishobora kwanduza ingirangingo zitandukanye z’ibimera, igatera ibihingwa, kandi ikanduza izindi ndwara ziterwa na virusi mu gihe zanduza nyirubwite, bigatera ibimenyetso by’indwara z’ibimera.Ibihingwa bya parasitike nematode yavumbuwe kugeza ubu harimo imizi-ipfundo nematode, ibiti bya pinusi nematode, soya cyst nematode na stem nematode, nematode ibanziriza nibindi nibindi.

Fata imizi-ipfundo nematode nkurugero:

Imizi-ipfundo nematode nicyiciro cyingenzi cyibimera bitera indwara ya nematode ikwirakwizwa kwisi yose.Mu turere dushyuha no mu turere dushyuha hamwe n’imvura nyinshi n’ikirere cyoroheje, ingaruka za nematode y’umuzi zirakomeye cyane.

Kubera ko indwara nyinshi za nematode zibaho kumuzi yibimera, biragoye gukoresha imiti yica udukoko.Kandi biroroshye cyane kubisekuru guhurira muri pariki yimboga, bibaho cyane, bityo nematode yumuzi-ipfundo muri rusange biragoye kubigenzura.

Imizi-ipfundo nematode ifite abantu benshi bakira, kandi irashobora kwanduza ubwoko burenga 3000 bwakirwa nkimboga, ibihingwa byibiribwa, ibihingwa ngandurarugo, ibiti byimbuto, ibiti byimitako n ibyatsi bibi.Nyuma yuko imboga zanduye nematode yumuzi, ibihingwa byo hejuru-bigufi ni bigufi, amashami namababi bigabanuka cyangwa bigahinduka umuhondo, imikurire irahagarara, ibara ryibabi ryoroshye nkaho kubura amazi, imikurire yibiti birwaye cyane ni intege nke, ibimera bigenda byiyongera mu ruzuba, kandi igihingwa cyose gipfa mubihe bikomeye.

Indwara ya nematiside gakondo irashobora kugabanywamo fumigants na non fumigants ukurikije uburyo butandukanye bwo gukoresha.

Fumigant

Harimo hydrocarbone ya halogenated na isothiocyanates, naho non fumigants harimo fosifore kama na karbamate.Methyl bromide na chloropicrin ni hydrocarbone ya halogene, ishobora kubuza intungamubiri za poroteyine ya nematode y'imizi hamwe na biohimiki ikora mu myanya y'ubuhumekero;Carbosulfan na Mianlong ni methyl isothiocyanate fumigants, ishobora kubuza guhumeka imizi ipfundo rya nematode kugeza gupfa.

Ubwoko bwa fumigation

Muri nematicide idafite fumigant, thiazolphos, phoxim, phoxim nachlorpyrifosni fosifore kama, karbofuran, aldicarb na karbofuran ni ibya karbamate.Non fumigant nematicides isenya imikorere ya sisitemu yimikorere yimizi ipfundo rya nematode muguhuza na acetylcholinesterase muri synapses yumuzi nematode.Mubisanzwe ntibica imizi ipfundo rya nematode, ariko birashobora gutuma gusa imizi ipfundo nematode itakaza ubushobozi bwo kumenya uwakiriye no kwandura, kuburyo bakunze kwitwa "nematode paralysis agent".

Kugeza ubu, nta nematicide nyinshi nshya, muri zo harimo fluorenyl sulfone, estiro spiroethyl, bifluorosulfone na fluconazole ni abayobozi.Abamectinna thiazolophos nayo ikoreshwa kenshi.Byongeye kandi, kubijyanye n’imiti yica udukoko twangiza udukoko, Penicillium lilacinus na Bacillus thuringiensis HAN055 yanditswe muri Konuo nayo ifite isoko rikomeye ku isoko.
