Zviratidzo zvengozi Kunyanya kukuvadza mashizha, mazhinji acho ari chirwere chekutanga pamashizha ezasi ane senescent pakati nepakati uye pakupera kwekukura.Mashizha embatatisi anotapukirwa, kutanga kubva kumucheto weshizha kana kumuromo, mavara egirinhi-brown necrotic anoumbwa padanho rekutanga, uye zvishoma nezvishoma anokura kuita anenge akatenderera kusvika ku "V" -yakaita grey-brown yakakura necrotic mavara, ane mhete isingataridzike. , uye micheto yekunze yezvivara zvinorwara zvinowanzova Chlorescence uye yellowing, uye pakupedzisira mashizha anorwara ane necrotic uye anopisa, uye dzimwe nguva zvishoma zvishoma zvakasviba zvakasviba zvinogona kubudiswa panzvimbo dzine chirwere, kureva, conidia yepathogen.Dzimwe nguva inogona kukanganisa madzinde nemizambiringa, ichigadzira isina kuumbwa grey-brown necrotic makwapa, uye gare gare inogona kuburitsa madiki mavara ebrown muchikamu chinorwara.
Occurrence pattern Blight yembatatisi inokonzerwa neutachiona hwefungus imperfect fungus Phoma vulgaris.Iyi pathogen overwinter muvhu ine sclerotium kana hyphae pamwe chete nehurwere tishu, uye inogonawo overwinter pane mamwe masara evaenzi.Kana mamiriro egore rinouya akakodzera, mvura inonaya inosasa utachiona hwepasi pamashizha kana madzinde kuti huite utachiona hwekutanga.Mushure mokunge chirwere ichi chichiitika, sclerotia kana conidia inobudiswa muchikamu chinorwara.Zvirwere zvinodzokororwa nerubatsiro rwemvura inonaya zvinoita kuti chirwere ichi chipararire.Kudziya uye kunyorova kwakanyanya kunobatsira kuitika uye kupararira kwechirwere.Chirwere ichi chakanyanya kuoma muminda ine ivhu rakashata, kutarisira kwakakura, kudyara zvakanyanya, uye kusakura kwechirimwa.
Nzira dzekudzivirira uye dzekudzora Matanho ekurima: sarudza nzvimbo dzakaorera dzekudyara, ziva kusimba kwekudyara kwakakodzera;kuwedzera organic fertilizer, uye zvakakodzera kushandisa phosphorus uye potassium fertilizer;simbisa manejimendi panguva yekukura, kudiridza uye topdressing munguva, kudzivirira kuchembera kwechirimwa nguva isati yakwana;nenguva yabva kukohwa Bvisa mitumbi ine zvirwere mumunda woiparadza nepakati.
