Nkhaka zamphesa zomwe zimamveka mozizwitsa ndikufa zimatha kukhala ndi kachilombo ka bakiteriya. Nkhaka bakiteriya imafalikira ndi kachilomboka kakang'ono. Pali zambiri zomwe mungathe kuchita kamodzi ngati mipesa imayambitsidwa ndi bakiteriya, koma mungatenge nthawi yayitali kuti muteteze mitengo yanu ya nkhaka .
Zizindikiro za Bacterial Wilt
Chizindikiro chimodzi cha mabakiteriya ndizo zomera zomwe zimafota ngakhale atakhala ndi madzi okwanira.
Mukhozanso kuyesa nkhaka mwa kudula tsinde loipa kwambiri pamwamba pa nthaka ndikulikulitsa. Ngati mankhwala owopsa, owopsa amachoka, ndibakiteriya. Dothi lochepa kwambiri limeneli limapangitsa kuti zomera zisawonongeke, choncho chomeracho sichitha kulowa m'madzi omwe amafunikira.
Kuwonongeka kwa nkhaka kumachitika mwamsanga mu nkhaka ndi muskmelons. Pakatha mlungu umodzi wa matenda, mukhoza kuyamba kuona zofiira pamasamba. Pakatha milungu iwiri mpesa wonse udzakhala wilting ndipo zipatso zidzayamba kuwoneka zazing'ono ndi zopunduka. Nthaŵi zambiri, palibe chikasu cha masamba .
Zifukwa za Bakiteriya Wilt pa Nkhaka
Bacterial wilt amayamba chifukwa cha bakiteriya Erwinia trachephila , yomwe imafalikira pamene kachilomboka kameneka kameneka kapena kachikale kameneka kamapezeka pambewu. Mabakiteriya amatha kugonjetsa matenda a kachilomboka, kapena tizilombo tingatenge pamene tikudyetsa kwinakwake. Maluwa amenewa akhoza kufalitsa kachilomboka kameneka.
Chiwombankhanga cham'mimba chimakhala pafupifupi 1/4 masentimita yaitali ndipo chimakhala ndi mizere itatu yakuda pamapiko ake achikasu. Chiwombankhanga chodziwika ndi mtundu wobiriwira wobiriwira koma uli ndi madontho 12 akuda. Kutayidwa nkhaka kafadala chakudya cha cucurbits (nkhaka, mavwende, sikwashi, maungu, ndi nkhumba) ndi zomera zina.
Mphutsi ya mbozi zonse ndi zoyera ndi mitu yakuda ndi mbuyo ndipo zimapezeka mu nthaka pansi pa mitengo yanu ya nkhaka . Mazirawo ndi ofunika kwambiri lalanje-chikasu.
Kusamalira Nkhaka Bakiteriya Wilt
Njira yabwino yopewera mabakiteriya ndiyo kusunga zomera zanu. Nkhaka kafadala amakonda kudya pa wilted zomera, ndipo wilted zomera kale zovuta matenda. Onetsetsani kuti mbeu zanu zimathiridwa madzi komanso kusamalidwa bwino. Mabakiteriya amafunika bala, monga kuluma kachilomboka kapena kupweteka, kuti alowemo, kotero samalani kuti musamawononge mitengo yanu ya nkhaka. Malangizo ena oletsa mabakiteriyawa ndi awa:
- Sankhani mitundu yotsutsana: Two nkhaka mitundu yomwe imakhala yolekerera nkhaka kafadala ikuphatikizapo 'Ufulu' ndi 'Wisconsin SMR58'.
- Yang'anani kumayambiriro: Kusunga nkhaka m'munda wanu ndi njira yabwino kwambiri yolamulira . Nyamakazi imasonyeza kumayambiriro kwa masika ndikuyika mazira awo pamunsi mwa masamba. Yang'anirani zizindikiro za nyamakazi, mukangokadzala nkhaka zanu. Onetsetsani masambawo ndikuwononge matumba a dzira lirilonse powachotsa kapena kuwamasula.
- Zolinga zopangira: Mungateteze mitengo yamakono oyambirira mwa kuphimba zomera ndi chivundikiro choyandama kapena cheesecloth. Sungani pansi pa chivundikiro kuti maluwa asapsekere pansi pake. Kumbukirani kuchotsa chivundikirocho pamene maluwa awonekera.
- Lingalirani mankhwala ophera tizilombo: Nkhaka zimakhala zovuta kwambiri kwa mankhwala ophera tizilombo, choncho muzizigwiritsire ntchito monga njira yomaliza ndikutsatira ndondomekoyi mosamala. Zomera za mbozi zimagwira ntchito kuyambira madzulo mpaka m'mawa; Kupopera mbewu mankhwalawa madzulo kumakhala kovuta kwambiri. Rotenone ndi tizilombo toyambitsa pyrethrin tikulimbikitsidwa.
Mwamwayi, ngati mipesa yanu yatenga kachilomboka, idzafunika kukoka ndi kuchotsedwa. Palibe mankhwala ochizira mabakiteriya. Chotsani mipesa yonse kugwa.
