Potato simila nematode: incazelo, ubuhlungu, ukulwa

Potato simila nematode - isifo libhekene kuyabonakala lesion nezilimo eziyizigaxa (bheka isithombe). Imbangela sifo eyisibungu amancane benesimo filamentary. Empeleni, igama isifo, "segolide nematode amazambane" livela egameni la magciwane ( "nima" lihunyushwa ngokuthi "string", futhi «oides» ngokuthi "njenge-" noma "ngentambo-like"). Emvelweni kungenzeka lezi zibungu ezincane nazo emhlabeni futhi izingqimba ebusweni (ngokuvamile abafika kwabangu-10 cm ejulile), namanzi ice-Antarctic futhi entwasahlobo kushisa. Ikakhulukazi eziningi kubo namanje emhlabathini (eziningana ayisigidi imitha square).

indlela yokuphila

Potato simila nematode kuhlaba mouthparts yayo umkhonto-odongeni yeseli isitshalo futhi sifaka ngamathe yayo kulo, esikhundleni salokho, oguqula iseli ku impahla siyagwinyeka ngoba isibungu futhi kusiza ukunyakaza amagciwane ku tuber.

amaqanda amaningi nematode walala noma enhlabathini noma ngqo ukutshala izimpande isisulu. Potato simila nematode ukuchamisela izingane luba uhlobo egumbini zokuzivikela. simila amancane ngalinye ezifana ingaqukatha kufika ku ezingamakhulu amathathu izibungu. Isikhathi ukuphila (noma, kunalokho, okusinda) impela high - iminyaka engu-10 (nokuningi).

umonakalo

ngokushesha Izibungu okubuya izinhlumba uqale singagxila impande zalesi sihlahla. Into lapho sifaka i-nematode amazambane simila, ibulala tuber amaseli bese ngaleyo ndlela siyehla ekukhuleni kwayo. Umoba ibuna, kushiya zincipha. Lesi sitshalo ekes out dabukisa yokuphila kabuhlungu. Potato simila nematode ibhebhetheka ngokushesha okukhulu. Ngaphezu kwalokho, nezilimo eziyizigaxa kuthinteka kalula ukungena kwamagciwane nezinye izifo. Ngisho nematodes ukuthwala amagciwane, ukupheka, ngaphandle esigabeni yezinye Amagciwane. Ngokwesibonelo, tuber nematode ekhiqizwa enzyme ukuthi ukwenza isitshalo ukungenwa okulimaza sekwephuzile.

Nematode - into ngokuhlukaniswa

"Sick" amazambane ingeniswe esuka eSouth America kanye kwezifunda zezintaba zase-Andes. It wasuka lapho ukusabalala nematodes emhlabeni wonke. Namuhla worm itholakala emazweni 42. Futhi - naphezu kweqiniso lokuthi le nematode - isikhungo ngokuhlukaniswa. Amabanga ezinkulungwane amakhilomitha, njengoba wazi, isibungu yisinanakazana ngokwawo bengayi. Futhi ibekezelele endoda ngokwayo. Kanjani? Disappointingly elula: indaba isitshalo ukuze amasondo izimoto, ukunisela izinhlelo, e machining amathuluzi, ngisho e izicathulo zakho siqu.

Ngeshwa, indawo yokungenwa yizifo ngokucindezela amagciwane ngaphezulu. It is hhayi ngaphandle ukuthi ukungabi khona izindlela eziphumelelayo yokulwa nezifo amazambane (nematode) kuzolungiswa yonke indawo.

Ukuzivikela ezifweni

Njengoba kobukhulu okusezingeni eliphezulu, konke balimi nabalimi, wathola izimpawu nolokubhujiswa imifino nge lesi silwanyana, kutuswa ukubike lokhu neThimba of Plant Quarantine (abamele ayatholakala kuzo zonke izindawo).

Manje sikwazi ukukhuluma yokuzalanisa izinhlobo nematode malovospriimchiva. Phakathi kwabo - "Latona", "anosta", "Picasso" futhi "impala" (Holland).

Kukhona imithi emisha. Ngiye ngabonisa kakade ngokwabo ukuba granulate nematicide basamid. Wasebenzisa ngaphambi seeding (zokutshala) ikakhulukazi endlini ngaphansi utamatisi kanye ukhukhamba, nginihlakaze, iyunifomu futhi ukushumeka enhlabathini 40 g we izidakamizwa ngamunye imitha square. Ukuvikelwa amazambane lo izidakamizwa ingakamiswa wafunda.

Amanye amazwe athathwa ngaphezulu izinyathelo ezinqala - ukucutshungulwa isikhala ukukhiqizwa geterofosom (80 kg / ha) kanye thiasone (270 kg / ha) ngaphambi instillation we amahlamvu onegciwane inhlabathi kulandele chlorination (ethela bleach).
