Nakuba i-plant parasitic nematodes iyingxenye yezingozi ze-nematode, ayizona izinambuzane zezitshalo, kodwa izifo zezitshalo.

Isifo se-plant nematode sibhekisela ohlotsheni lwe-nematode olungakwazi ukuqeda izicubu ezihlukahlukene zezitshalo, lubangele ukukhula kwezitshalo, futhi ludlulisele amanye amagciwane ezitshalo ngenkathi luthelela umsingathi, lubangele izimpawu zezifo zezitshalo.Ama-nematode ezinambuzane ezitshaliwe asetholakele kuze kube manje afaka i-root-knot nematodes, i-pine wood nematodes, i-soybean cyst nematodes kanye ne-stem nematodes, i-forerunner nematodes njll.

Thatha i-root-knot nematode njengesibonelo:

I-Root-knot nematodes iyisigaba esibaluleke kakhulu se-plant pathogenic nematodes esatshalaliswa kabanzi emhlabeni wonke.Ezifundeni ezishisayo nezishisayo ezinemvula eningi nesimo sezulu esipholile, ukulimala kwe-root-knot nematode kubi kakhulu.

Njengoba izifo eziningi ze-nematode zenzeka ezimpandeni zezitshalo, kunzima ukusebenzisa izibulala-zinambuzane.Futhi kulula kakhulu ukuthi izizukulwane zidlulele ezindaweni zokugcina izithombo zemifino, okwenzeka kakhulu, ngakho-ke ama-nematode e-root-knot ngokuvamile anzima ukuwalawula.

I-Root-knot nematode inezinhlobonhlobo zezilwane, futhi ingabulala izinhlobo ezingaphezu kuka-3000 zezilwane ezifana nemifino, izitshalo zokudla, izitshalo zemali, izihlahla zezithelo, izitshalo zokuhlobisa kanye nokhula.Ngemuva kokuthi imifino itheleleke nge-root-knot nematode, izitshalo ezingenhla zifushane, amagatsha namaqabunga ayashwabana noma aphuzi, ukukhula kuyancipha, umbala weqabunga ulula njengokungathi ukuntuleka kwamanzi, ukukhula kwezitshalo ezigula kakhulu. buthaka, izitshalo ziyabuna ngenxa yesomiso, futhi sonke isitshalo siyafa ezimeni ezinzima.

Ama-nematicides endabuko angahlukaniswa abe yizinto ezifuthayo nezingezona umfumi ngokwezindlela ezihlukene zokusebenzisa.

I-Fumigant

Kufaka phakathi ama-halogenated hydrocarbons nama-isothiocyanates, futhi ama-nonfumigants afaka i-organic phosphorus ne-carbamate.I-Methyl bromide ne-chloropicrin ama-halogenated hydrocarbons, angavimbela ukuhlanganiswa kwamaprotheni e-root knot nematodes kanye nokusabela kwamakhemikhali enqubo yokuphefumula;I-Carbosulfan kanye ne-Mianlong ziyingxenye ye-methyl isothiocyanate fumigants, engavimbela ukuphefumula kwe-root knot nematodes ekufeni.

Uhlobo olungafusi

Phakathi kwe-nematicides engeyona ifumigant, i-thiazolphos, i-phoxim, i-phoxim kanyei-chlorpyrifosziyingxenye ye-organic phosphorus, i-carbofuran, i-aldicarb ne-carbofuran ingeye-carbamate.Ama-nematicides angafumi acekela phansi umsebenzi wesimiso sezinzwa se-root knot nematodes ngokubophezela ku-acetylcholinesterase kuma-synapses of root knot nematodes.Ngokuvamile azibulali i-root knot nematodes, kodwa zingenza kuphela i-root knot nematodes zilahlekelwe amandla okuthola umsingathi futhi zithelele, ngakho-ke zivame ukubizwa ngokuthi "ama-nematode paralysis agents".

Njengamanje, awekho ama-nematicides amaningi amasha, phakathi kwawo i-fluorenyl sulfone, i-spiroethyl ester, i-bifluorosulfone ne-fluconazole abaholi.I-Abamectinfuthi i-thiazolophos nayo isetshenziswa njalo.Ngaphezu kwalokho, ngokwezibulala-zinambuzane zebhayoloji, i-Penicillium lilacinus ne-Bacillus thuringiensis HAN055 ezibhaliswe e-Konuo nazo zinamandla emakethe aqinile.
