Mashizha ane chirwere emeadow bluegrass nefine-leaved fescue anochinja kubva pakuva yero kuenda kubrown kubva kumusoro kusvika pasi, uye obva ava grey, kusvika shizha rese rafa. Mhando dzakasiyana dzezvirwere zvinokonzera zviratidzo zvakasiyana. Semuenzaniso, kana Curvularia crescentus ikatapukira meadow bluegrass, mavanga ari pamashizha ane chirwere anenge akaita seoval kana fusiform, pakati pemavanga acho anenge grey, nzvimbo dzakatenderedza dzine brown, uye kune ma halos eyero kunze. Kana mashizha akafukidzwa nemavanga, anofa.
Mamiriro ezvinhu eCurvularia leaf blight
Tembiricha: Zviri nyore kuitika kana tembiricha yakakwira yasvika pamadhigirii makumi matatu munzvimbo ine hunyoro hwakawanda.
Zvinhu zvinotapukira: Zvinotapukira uswa huri kusangana nematambudziko ekupisa kwakanyanya kana kuti zvinomira kukura nekuda kwekupisa kwakanyanya. Uswa, zvirimwa zvakasiyana-siyana zvezviyo, uye sora reuswa. Huswa hwakarimwa zvisina kunaka, husingatarisirwi zvakanaka, uye husina kukura zvakanaka. Hunogona kuitika munzvimbo dzine hunyoro uye mafetiraiza ane nitrogen yakawanda.
Nzira yekuparadzira: Kupararira nemhepo nemvura.
Kudzivirira uye kurapa chirwere cheCurvularia leaf blight
Mbeu: Sarudza mbeu dzine uswa husingarwari nezvirwere uye husina zvirwere, uye sanganisa mhando dzakasiyana dzembeu dzeuswa.
Kudyara nekuisa manyowa: Vhara ivhu nemazvo paunenge uchidyara, nyatsoteerera kutarisirwa kwembeu, isa nitrogen fetereza zvine mwero, usashandise zvakanyanya pakutanga kwechirimo nepakati pezhizha, uye wedzera phosphorus nepotassium fetereza.
Kudiridza: Kudiridza kunofanira kuitwa mangwanani, kudzivirira kudiridza manheru, kudiridza zvakadzama uye zvakakwana, kuderedza kudiridza nguva nenguva, uye kudzivirira kuungana kwemvura pahuswa.
Kucheka: Tarisa kureba kwekucheka, hurefu hudiki i5 kusvika 6 cm.
Nzvimbo: Bvisa mashizha asara euswa hune chirwere nehwakafa nenguva mushure mekuchekerera, uye chenesa huswa hwakafa nguva nenguva.
Matanho ekurapa chirwere chemashizha cheCurvularia
Pakudyara mbeu, sanganisai mbeu nehuwandu hwakakodzera hwe triadimefon wettable powder kana 50% thiram wettable powder. Pfafadzai uswa nemushonga wefungi panguva yekudzivirira nekudzivirira chirwere ichi pakutanga kwechirwere.
