Ko makwenzi ako ane chii chinoratidzika chiri kufa chichivhara nemicheka mitsvuku kana tsvuku mukati mavo? Izvi zvinogona kuva chiratidzo chinotaura nezve tsvuku tsvuku. Tsvuku tsvuku ndiyo chirwere chinonzi turfgrass chinowanzokonzerwa nemazinga akaderera e nitrogen muvhu. Chirwere ichi chinowanzoonekwa pakati pekupera kwaApril uye pakati peJune asi chinogona kuratidza munguva yakawanda yekukura kwegore. Nguva dzaro dzinoshingaira dziri mumwedzi waMay neJune apo kutonhora kweusiku kwakanamatira kunotarisana nemafuta makumi manomwe nemasere uye mashizha akakura zvakanyanya, achishandisa zvizhinji zve nitrogen muvhu.
Susceptible Grasses
Nguva yakanakisa uswa hunowanzove hunonyanya kusvibiswa tsvuku tsvuku. Mhando dzakasiyana dzinosanganisira red fescue, ryegrass, Kentucky bluegrass, uye bentgrass. Mimwe mitambo yakasiyana-siyana inowanzoomeswa. Izvi zvinosanganisira "Bilart" uye "Claudia" dzakanaka kwazvo, "Chateau" Kentucky bluegrass, uye "Pennant" inogara bhagrass.
Inonzi Red Thread Inouraya Gorosi Here?
Apo nzvimbo dzakasvibiswa dzouswa dzichiita se dzakafa, tsvuku tsvuku hairi kuuraya uswa. Iyo fungus inobata tsvina inogara mumatanda uye ivhu uye inogona kupararira nevakafa vechirwere chekugadzirisa uye nekuchera uye mamwe magetsi ekugadzirisa. Iyo mikiki inokura iyo inowanikwa mubusva haiparadzi korona kana midzi yemiti, naizvozvo uswa hauna kuurayiwa nefungus.
Mamiriro ekutsigira Red Thread
Tsvuku tsvuku inogona kuitika munzvimbo dzakasiyana-siyana dzakasiyana asi inowanzoonekwa munzvimbo dzine mvura yakakwirira kana kuti mvura yakakwirira mumucheto kwechando kusvika kuzhizha.
Mamiriro ekutanga anobatsira tsvuku tsvuku ndeye:
- Low levels of nitrogen
- Kutsigira pakati pe 68 F ne75 F
- High humidity
Kuziva Red Thread
Tsvuku tsvuku ndeyekukura kwemafunguswe Laetisaria fuciformis uye inowanikwa nenzira mbiri pamashizha (mashizha) euswa uswa. Chimwe chimiro chine matavi akafanana netambo, dzimwe nguva akaenzaniswa nevhuvhuni, inonzi sclerotia.
Chimwe chimiro chinoratidzika sechitsvuku chine mazamu mashizha e mycelium. Nzvimbo dzakakanganiswa kazhinji dzinotenderera uye dzinotangira kubva 4 kusvika ku 8 masendimita muhupamhi. Uswa hunowanzova tani kana kuti tsvuku tsvuku pasi pezvitsvuku zvinowedzera.
Tsvuku tsvuku inowanzovhiringidzwa nehosha inonzi pink patch. Izvo zvinewo maitiro akafanana nea pink rose mold uye dollar spot, uye zvirwere zvose izvi zvinogona kuonekwa panguva imwechete yegore. Zvisinei, tsvuku tsvuku inogadziriswa yakanzwisiswa neyo-antler-like structure kana mycelium masumbu.
Chinoita Kuti Mushonga Wako Uve Wakawedzerwa
Munenge mapavi ose anokonzerwa nehope tsvuku yefungus. Zvisinei, hazvisi zvisinganzwisisiki kuti mamwe madonhwe ave nematambudziko akawanda kunze kwekwakavakidzana, nemhaka yemamiriro akasiyana evhu, kuchengetedza, nemadziro emvura. Chinokonzera tsvuku tsvuku nemamwe zvirwere zvekutuka zvinogona kunzwisiswa nekutarisa zvinhu zvepatatu yezvirwere. Izvi zvinoshandiswa kuratidza kuti fungi inokura sei pazvirimwa.
Zvinhu zvitatu zviri mumutsetse uyu wezvirwere ndezvomunhu anogadziriswa, ane pathogen kana chirwere pachayo, uye nzvimbo inofanirwa nekukura kwezvirwere. Izvo zvinomera uswa huripo mu nitrogen uye huri kukurumidza kukura kudarika mumwedzi yapfuura. Iyo pathogen inowanikwa mubhedha rakasvibirira yemukati uye hazvibviri kubvisa zvachose.
Apo bindu racho risina simba, uye kutonhora uye hukama hwehukama hwakanaka kune fungal kukura, tsvuku tsvuku ichaonekwa uye inoramba ichikura.
Mushonga weRed Thread
Vadzidzisi veminda vanowanzoshamisika kuti chii chinogona kuitwa kuti ibvise tsvuku tsvuku pamasese kana ichiratidza gore negore. Iyo mishonga ndeyokuvhiringidza hutatu hwechirwere kuitira kuti fungus irege kukura. Sezvo zvisingakwanisi kubvisa pathogen kana kudzora mamiriro okunze, nzira yakanakisisa yekugadzirisa tsvuku tsvuku ndeyokutarisa iyo inogadziriswa yemiti yekusimbisa uye inosimbisa iyo nemafuta.
Chirongwa chekutanga chetsvuku ndechekudiridza uswa nemafuta akakwana e nitrogen sechikamu chepurogiramu yekudya inoenderera mberi. Nitrogen inoshandiswa kumucheka mukuwa ichasimudzira kudzokazve kwemazuva ekupedzisira, asi zvizhinji zvekuti nitrogen ichave yapera nekupera kwematsutso.
Panguva iyoyo, inowanzobudirira kushandisa 0.2 mapaundi e nitrogen pa1000 square mazamu echando, uye izvi zvinogona kugadziriswa kuitira ivhu rako nemamiriro ekunze. Ngwarira kuti zvinogona kutora makore maviri kana kupfuura ekupa kudya zvakanyatsonaka kuti kudzivirira tsvuku dzisati dzadzoka munguva yegore.
Kurapa tsvuku tsvuku nemakemikari kazhinji hazvidikanwi uye hazvikurudzirwi zvekugara maruva, asi makemikari inzira inogadziriswa yezviitiko zvakanyanya. Izvi zvinosanganisira kushandiswa kwefungicide, kazhinji chimiro cheQol inhibitor (strobilurins). Kana iwe uchida kurapa tsvuku tsvuku nemakemikari, bvunzurudza unyanzvi hwekugadzirwa kwegwenzi kuti uwane mazano.
