ziviso Rhizoctonia solani chirwere chefungal chinoisa njodzi huru kune zvirimwa zvembatatisi pasi rose. Iyi pathogen inoparadza inokonzera zviratidzo zvakasiyana-siyana, zvinosanganisira stem canker, kunyorova, dema scurf, mambure eganda, uye tuber kukura kukanganisa. Kuti uderedze kukanganiswa kweRhizoctonia solani, varimi vanofanirwa kutora nzira yakabatana inosanganisa akati wandei mazano anoshanda. Ichi chinyorwa chichaongorora mazano aya uye chinopa ruzivo rwakakosha mukugadzirisa chirwere chefungal ichi nemazvo.
Kunzwisisa Rhizoctonia Solani Rhizoctonia solani ivhu rinotakurwa nevhu rinonyanya kukanganisa zvirimwa zvembatatisi. Inokura mumamiriro ekudyara kunotonhora uye inogona kurarama muvhu kwenguva yakareba. Chirwere ichi chinoratidzika sechitsvuku-ruvara necrotic patches, inozivikanwa se cankers, pamidzi yakakanganiswa, madzinde, uye stolons. Machubhu ane hutachiona anoratidza dema scurf, kukanganisa kukura, uye zvimwe zvisizvo, zvichidzikisira hunhu hwavo uye kukosha kwemusika.
Integrated Approach for Disease Management
- Kushandisa Mbeu Yakachena: Kutanga nembeu isina chirwere kwakakosha kudzivirira kupinza Rhizoctonia solani muchiriho chembatatisi. Varimi vanofanira kuwana mbeu inocherechedzwa kubva kunzvimbo dzine chiremera, vachiona kuti yakavhenekwa uye kuti haina chirwere ichi.
- Kukurudzira Early Emergence: Kukurumidza kubuda kunobatsira mukuderedza njodzi yeRhizoctonia solani infection. Kudyara mbatatisi muvhu rakanyoroveswa, rinodziya uye kuchengetedza hunyoro hwakakodzera hunogona kukurudzira kukurumidza uye yunifomu kubuda, kuderedza kubatwa nechirwere.
- Kudzidzira Kutenderera Kurefu: Kutenderedza zvirimwa izano rinoshanda rekutarisira Rhizoctonia solani. Dzivisa kudyara mbatatisi kana zvimwe zvirimwa zvinotapukira mumunda mumwechete kwemakore akatevedzana. Nguva shoma yekutenderera yemakore matatu kusvika mana inogona kubatsira kuderedza mazinga einoculum muvhu, kuderedza kukanganiswa kwechirwere.
- Kuvandudza Utano Hwevhu: Kuchengetedza hutano hwevhu kwakakosha pakudzivirira Rhizoctonia solani. Maitiro akadai sekuwedzera organic zvinhu, kunatsiridza mvura yevhu, uye optimize pH mazinga anogona kugadzira nharaunda isina kunaka yekurarama uye kukura kwepathogen.
- Kushandisa fungicides: Fungicides inogona kushandiswa senzira yekudzivirira kudzora Rhizoctonia solani. Kushandisa fungicides panguva yekudyara kana kutanga kwemwaka wekukura kunogona kubatsira kudzivirira zvirimwa zvidiki kubva kuhutachiona. Nekudaro, zvakakosha kutevedzera mirairo yemugadziri uye mirau yemuno yekushandiswa kwakachengeteka uye kunoshanda.
mhedziso Rhizoctonia solani inounza dambudziko rakakura kune varimi vembatatisi, asi nekushandiswa kweiyo yakabatanidzwa nzira, kukanganisa kwechirwere ichi fungal kunogona kudzikiswa. Kutanga nembeu yakachena, kusimudzira kumera kwekutanga, kudzidzira kutenderera kwenguva refu, kuvandudza hutano hwevhu, uye kushandisa zvine hungwaru kwemishonga yefungidzi zvinogona kubatsira mukutonga kwechirwere kunoshanda. Nekutora nzira idzi, varimi vanokwanisa kuchengetedza mbesa dzavo dzembatatisi kubva kuRhizoctonia solani uye kuona goho rine hutano uye rinobudirira.

Kurudzira kumera kwekutanga nekupa mamiriro akakwana ekudyara.
Kuvandudza hutano hwevhu nekuwedzera organic matter uye kuchengetedza mvura yakafanira.
Dzidzira kudzora sora zvakanaka kuti uderedze makwikwi uye kudzvanywa kwechirwere.
Tevera zvinokurudzirwa zvirongwa zvefungicide, kana zvichidikanwa, kudzora chirwere.
Mubvunzo: Pane here tsika dzetsika dzinogona kubatsira kubata Rhizoctonia solani?
Dyarai mhodzi dzakachena, dzine utano.
Dzivisa kudyara muvhu rinotonhora uye rakanyorova.
Ipai nzvimbo yakakwana pakati pezvirimwa kuitira kutenderera kwemhepo kwakanaka.
Bvisa uye paradza tsvina yezvirimwa zvine utachiona mushure mekukohwa.
Chengetedza kubereka kwakakodzera kwevhu uye pH mazinga.
