Kutentha kumachepa, mpweya wolowera m'chipindamo umachepa, motero wakupha "root knot nematode" amawononga mbewu mochulukirapo.Alimi ambiri amanena kuti nyumbayo ikadwala, amangodikirira kuti afe.

Mizu ya nematode ikapezeka mu shedi, kodi muyenera kudikirira kuti mufe?Inde sichoncho.Mizu ya nematodes imawononga mbewu zambiri, makamaka mavwende, nightshades ndi mbewu zina.Mitengo ya zipatso monga citrus ndi maapulo idzakumananso ndi "tsoka" limeneli.Imatengedwa kuti ndi imodzi mwa tizilombo tovuta kwambiri kuwongolera chifukwa mphutsi zimabisala mumizu.

Mizu ya nematodes ikapezeka mu zipatso ndi ndiwo zamasamba monga tomato ndi tsabola, masamba a zomera amayamba kusanduka achikasu ndi kufota masana.Chakumapeto kwa chiyambi cha mizu ya nematode, zomera za zipatso ndi ndiwo zamasamba monga tomato ndi tsabola zimakhala zazing'ono, masamba ake ndi ang'onoang'ono ndi achikasu, ndipo pamapeto pake mbewu yonseyo imafota ndi kufa.

Lero, tiyeni tikambirane za mizu ya nematode, “yopha mizu” yovuta kwambiri kwa mlimiyu.

Zizindikiro za matenda a nematode muzu pa zomera

Nthawi zambiri, mizu yofananira ndi mizu yanthambi ndiyo yomwe ili pachiwopsezo kwambiri, ndipo palibe zinthu zokhala ngati chotupa chamikanda kumbuyo kwa chovulalacho, ndipo pali nematode yachikazi yoyera pambuyo powadula.Zizindikiro za mlengalenga ndi kuchepa ndi chikasu, kufota ndi kufa pamene nyengo yauma.Kwambiri matenda zomera kukula ofooka, amamera ndi chikasu.

Pa mbewu monga udzu winawake, mizu ya ulusi ndi nsonga zam'mbali zimaoneka ngati tinatake tozungulira mosiyanasiyana, ndipo mbali zamlengalenga zimafota pang'onopang'ono masana ndi kusanduka chikasu, ndipo mbewuzo zimakhala zazifupi komanso zachibwibwi.Zikavuta kwambiri, mizu imasanduka bulauni mpaka kuvunda ndi kufa.

Zomera zomwe zakhudzidwa zimakhala ndi mizu yochulukirapo kuposa momwe zimakhalira, ndipo timizu tokhala ngati mikanda timapanga pamizu ya ulusi.Mizu yophukira-yopanda nematodes imapanga ma granules achikasu, omwe amasandulika kukhala ma granules achikasu-bulauni.

Kodi mungapewe bwanji nematode ya mizu?

Osagwirira ntchito limodzi!Osagwirira ntchito limodzi!Osagwirira ntchito limodzi!Izi ndizofunikira kwambiri kuzindikira!

Mukamagula masamba obala zipatso monga tomato ndi nkhaka, kapena mukulera nokha mbande, muyenera kuyang'ana mizu mosamala kuti muwononge mizu ya nematode.

Kasinthasintha wa mbeu.Bzalani anyezi wobiriwira, adyo ndi mbewu zina pakati pamitunda ya zipatso ndi ndiwo zamasamba monga tomato ndi nkhaka.

Matenda akamakula, fukulani zomera zomwe zadwala nthawi yake, fukulani zonse ndi kuwaza ndi quicklime, ndi kukwiriranso mapu.Ngati matendawa si aakulu,abamectin, avimidacloprid, thiazophosphine, etc. angagwiritsidwe ntchito ulimi wothirira mizu.
