Kuoma kweuswa nebhakitiriya

Huswa hunowedzera kukosha mukuvaka nharaunda yemazuva ano. Mushure mekudyara, huswa hunogara huchikundikana kuwana runako rwaitarisirwa nekuda kwezvikonzero zvakasiyana-siyana. Chimwe chezviitiko ndechekuti mavara madiki eyero anoonekwa pamashizha, obva aoma ofa. Chimwe chezvikonzero zvechiitiko ichi ndechekuti huswa hune utachiona uye hunotambura nekuoma kwebhakitiriya, izvo zvinogona kuitika uye kupararira pahuswa hwakawanda. Kana chirwere chawedzera, chinoparadza girini rese munguva pfupi.
Kuongororwa kwakanangana kwebhakitiriya rinopwanya ndekwekuti kunotevera:
1. Kupararira uye kukuvadzwa kwebhakitiriya rinopwanya
Kuoma kwebhakitiriya kunogona kupararira uye kuitika pahuswa hwakawanda; kana chirwere ichi changobatwa, mavanga eyero anoonekwa pamashizha, obva akura zvishoma nezvishoma kuita mitsetse mirefu, uye mashizha acho anozoshanduka kuita yero-brown kuita brown yakasviba. Kana mavanga akapararira akanyorova mumvura, mavanga acho anooma nekukurumidza ofa.

2. Zviratidzo mushure mekubatwa nehutachiona hwebhakitiriya
Mushure mekutapukirwa, mavara akanyorova mumvura e1 mm anoonekwa pamashizha, ayo akaoma kuona nemaziso asina kupfeka. Mavara acho anokura zvishoma nezvishoma ochinja kuita grey-green kuita yero-brown kana chena kusvika afa. Mavara acho anokura oganhurana kusvika shizha rese rafa. Kana nharaunda yakapoteredza yanyorova, tupukanana tunobuda pamavara acho, tunogona kupinda mumaronda emiti kuti tuvande kana kukonzera chirwere. Chirwere chebacterial wilt pa creeping bentgrass chinotanga kuonekwa sechitsvuku kana mhangura chakafa.nzvimbo dzeuswa, zvichiteverwa nekufa kwemiti yakawanda yakapoteredza, zvichiparadza girini rose munguva pfupi.

3. Mwaka wekuoma kwebhakitiriya
Kuoma kwebhakitiriya kunowanzoitika munguva yechirimo neyematsutso apo nharaunda inochinja zvikuru kubva mangwanani kusvika manheru munzvimbo ine hunyoro uye inotonhorera. Hunhu hwemwaka ndiwo mudzi wechirwere. Kana chirwere ichi chatanga, mashizha anooneka ebhuruu-girini uye anosvava, uye mashizha anosvava uye zvishoma nezvishoma anoshanduka kuita brown kana pepuru, zvichizopedzisira zvaita kuti mashizha afe. ​​Matanda akakura semari yesimbi achaonekwa pahuswa hwakafa, uye munguva pfupi nzvimbo yakakura yehuswa ichasvava uye ichafa.

4. Zvinoita kuti pave nekuoma kwebhakitiriya
Chirwere chebacterial wilt chinopedza nguva isina kunaka chirimwa, uye chinozorwisa chirimwa chero nguva. Nzira dzekurwiswa nadzo dzakasiyana-siyana uye dzakaoma kudzora. Kana chirimwa chiine kukuvara kwekunze, chinogona kutapukirwa. Maronda anokonzerwa nekuchekererwa anogonawo kutapukirwa. Kwete izvozvo chete, chirwere ichi chinogona kupinda mugomba rega rega. Kana chirimwa chikatora mvura, chirwere ichi chinogonawo kupinda mumuviri wechirimwa kuburikidza nemakomba anopindirwa nemvura, kunyanya panguva yekudiridza nemvura yakawanda, izvo zvinokurumidzisa kupararira nekuitika kwechirwere ichi. Munzvimbo dzakaderera dziri pahuswa, chirwere chacho chakakomba uye chakaoma kudzora.

5. Kudzivirira uye kudzora kuonda kwebhakitiriya
Kufanana nenheyo dzese dzekudzivirira nekudzora, kudzivirira ndiko kunonyanya kukosha, uye pane zvinhu zviviri zvakakosha zvekudzivirira:

1. Pakuvaka huswa, mhando dzine majini akanaka anodzivirira zvirwere dzinofanira kusarudzwa.
Cherechedza: Mhando dzezvirimwa zvinokambaira zveToronto (C-IS), Nimisilla, Cohancey uye Bermudagrass mhando dzeTifgreen dzinogona kubatwa nechirwere ichi.

2. Kuedza kuri kuitwa munzvimbo yekukura: kutarisira nekungwarira, kutungamirirwa nenyanzvi, kutarisisa kuyerera kwemvura,kucheka zvine mwero, uye usafukidze jecha nguva nenguva.
Kana chirwere chikaitika, mushonga unoshanda uye une simba unofanira kushandiswa
Mishonga inorwisa mabhakitiriya: Oxytetracycline, streptomycin, nezvimwewo zvine mhedzisiro pakurwisa kupwanya kwebhakitiriya. Pakushandisa mushonga uyu, huwandu hwakawanda hwemishonga hunodiwa uye huwandu hwakawanda hwemushonga hunodiwa, izvo zvinogona kudzora chirwere ichi kwemavhiki mana kusvika matanhatu.
