Description:
Brown rust yegorosi (Puccinia recondita) is a parasitic fungus iyo inonyanya kukanganisa gorosi asiwo zvimwe zviyo. Fungusi iyi utachiona huviri uye hune hupenyu hwakakwana nemhando shanu dze sporulation. Muchikamu chezvinomera, fungus inogona kuvapo seaeciospores, dikaryotic mycelium, urediniospores, uye teliospores. Teleito- uye uredospores anonyanya kuchinjirwa kuchando. Muchirimo, ivo vanomera uye vanogadzira basidium ine mana basidiospores inotapukira iyo yepakati host - hazel kana cornflower. Spermatogonia inokura pamashizha emugadziri wepakati, uye mushure mekuyambuka-fertilization, aetsiospores inoumbwa iyo inokanganisa gorosi zvakananga.
Paradzira:
Fungi iyi yakapararira kwese kunorimwa gorosi. Naizvozvo, hapana nyika inodzivirirwa nechiitiko chekuparadzwa kukuru kwezvirimwa. Sezvo munzvimbo dzekuchamhembe uye muSiberia, spores haisati yaonekwa nekusanaya kwezhizha nekupisa, ivo vachararama zviri nani, uye mukana wechirwere chezvirimwa unowedzera zvakanyanya. Panguva imwecheteyo, gorosi rakasvibirira rinokanganisa zvirimwa zvechando uye zvechirimo, pamwe nemamwe marudzi ezviyo - bonfire, wheatgrass, wheatgrass, fescue, bluegrass.
Iyo fungus overwinters kunyanya mumhando ye mycelium mumashizha egorosi yechando uye zviyo zvemusango. Nekuonekwa kwedova remangwanani rakawanda, mbeu dzinotanga kumera muhuwandu. Iyo yepamusoro yekukura kwefungus inowira panguva yekutumbuka kwezviyo.
Kukosha kwehupfumi:
Ngura yebrown inokonzera kukanganisa kukuru kwekugadzirwa kwezviyo munyika dzakasiyana. Munyika Yedu, nzvimbo dzinowanzoitika chirwere ichi inharaunda yeVolga, nzvimbo yeCentral Black Earth uye nharaunda yeNorth Caucasus. Pano ngura yebrown inobata gorosi rinenge gore negore. Kuti kurwisa zvinobudirira mumiriri wechirwere ichi mumabhizinesi ekurima, anonyanya kugadzirwa marudzi egorosi uye zviyo zvinopokana nemashizha ngura anoshandiswa zvakanyanya.
