Clubroot (tuber disease)

Dambudziko rakakomba mumagadheni emumba, chirwere chekirabhu, chinogona kugadziriswa uchishandisa nzira dzakaratidzwa organic.

Inobata zvirimwa zvakawanda zvebrassica (kabichi, broccoli, cauliflower, zvichingodaro), clubroot chirwere chakakomba chirimwa muNorth America kumba magadheni. Zvinokonzerwa nefungus yevhu. Plasmodiophora kabichi iyo inobata zvirimwa zvinotapukira kuburikidza nemvere dzemidzi. Midzi ine chirwere inozvimba, kushapa uye kushapa (kufanana nekirabhu), uye kazhinji kutsemuka nekuora. Nekuda kweizvozvo, zvirimwa zvinonetseka kutora mvura nekudya zvakanaka.

Zvirimwa zvinowanzokura zvisina kunaka uye zvinosvava pakupisa kwezuva; zvirimwa zvinowanzouya zvipenyu pausiku hunotonhorera. Mashizha ekunze anogona kuita yero, yepepuru, kana shava. Midzi yekirabhu inoderedza goho uye zvinogona kukonzera kutadza kwegoho zvachose.

Fungal spores inogona kuparadzirwa nemhepo, mvura uye maturusi ekurima. Kukura kwechirwere kunogona kuitika pasi pemamiriro akasiyana-siyana, asi kunofarirwa nekunyorova kwakanyanyisa, ivhu rakaderera pH, uye tembiricha yevhu iri pakati pe64 ne77˚F. Spores inogona kuramba iri muvhu kusvika kumakore gumi.

Лечение

1. Fungicides ichaita NOT rapa iyi microorganism yevhu.
2. Sarudza mhando dzisingachinji pese pazvinogoneka.
3. Edza kudzivirira chirwere ichi nekuchengetedza gadheni rako rakachena uye kutenderedza mbesa.
4. Ramba uchifunga kuti chirwere chechirwere chinogona kuramba chiri muvhu kusvika kumakore makumi maviri. Kana tuber iripo, unogona kusvibisa ivhu.
5. Dzora masora anotapukira—masitadhi, radish, chikwama chomufudzi—angabatwa neutachiona kuderedza kupararira kunobvira kwechirwere.
6. Nyatsobvisa zvirimwa zvazara uye bvisa maturusi egadheni (chikamu chimwe chebhisha kusvika pazvikamu zvina zvemvura) mushure mekushandisa.
7. Simudza ivhu pH kune imwe alkaline level ye7.2 nekuwedzera oyster shells kana dolomite lime kubindu mukudonha. Yakareruka uye inokwanisika yekuongorora ivhu kits inowanikwa kuti igare ichiongororwa pH.

*Kupisa ivhu rako, unofanirwa kusiya tarp yepurasitiki yakajeka pavhu kwemavhiki e4-6 panguva yekupisa kwegore. Solarization yevhu inoderedza kana kubvisa tupukanana tunogara muvhu, kusanganisira nematodes, fungi, tumbuyu, sora nemhodzi yesora.
