Monga mitengo yambiri yokongola ndi zitsamba, magnolias akhoza kukhala ndi mawanga akuda kapena a bulauni. Pamene vutoli liri lalikulu, lingayambitse masamba ndipo akhoza kutsitsa mtengo womwe ulibe masamba opanda masamba. Vutoli likhoza kuchitika mvula, ndipo mwina chifukwa chake magnolia, mtengo wambiri m'madera akum'mwera chakum'maŵa, nthawi zambiri umakhudzidwa.
Mafuta a Magnolia Kawirikawiri Amayambitsa Bowa
Kuwonongeka kwa tizilombo, mabakiteriya, kapena matenda a tizilombo kungayambitsenso mitundu yosiyanasiyana ya mawanga ku magnolia masamba.
Malingana ndi buku la Pacific Northwest Plant Plant Management Handbook, kachilombo kameneka kangakhalenso khunyu: Pseudomonas syringae pv. syringae. Komabe, nthawi zambiri tsamba la magnolia limatuluka ndi bowa limodzi lofanana:
- Cladosporium spp.
- Coniothyrium spp.
- Phyllosticta magnoliae
- Septoria spp.
Mawanga enieni samakhala achida nthawi zonse, mwa njira. Zikhoza kukhala zofiirira, tani, kapena zofiira. Nkhumba zomwezo kapena zokhudzana nazo zingakhudze zomera zambiri, komanso. Mukawona tsamba la masamba pamagnolia wanu, ndibwino kuti pakhomo lina pakhomo panu pakhale maonekedwe a masamba a fungal.
Mafangasi Akukula M'mavuto Ambiri
Bowa limakula bwino mmavuto. Monga momwe yunivesite ya Connecticut (UConn) Extension imawonera, pamaso pa fungal spores, zonse zimatengera "filimu yamadzi" pa tsamba la spores kuti imere ndi kulowa mkati mwa tsamba. Ndi pomwepo masambawo amadwala matenda.
Malo amtunduwu amawonekera nthawi yamvula kapena yamvula, ndipo nthawi zambiri amadzikonzanso paokha pamene dzuwa limalowa, nyengo yamvula imabwerera. M'nyengo yotentha, nyengo yamtendere, mitengo yokhwima bwino imatha kuona maonekedwe a masamba pachaka, ndipo nthawi zambiri sichida nkhawa kwambiri
Kuchitira Leaf Spot
Akatswiri ambiri samaona kuti tsamba laling'ono ndilofunika kudandaula kwambiri pamene likuchitika pachithunzi chokhwima cha mtundu uno, monga nyenyezi ya magnolia , kapena sauce magnolia , Malangizo awo kawirikawiri ndi kuchotsa masamba a bulauni omwe ali ndi matenda ndiye muwatulutse bwino.
Lingaliro ndikuteteza bowa kuti asafalikire. Musatayike masamba omwe ali ndi matendawa powawongolera, chifukwa fungal spores ikhoza kukhalabe mu kompositi ndikufalitsidwa kwa zomera zina.
Koma, monga UConn Extension inanenanso, tsamba la masamba limakhala matenda oopsa kwa mitengo yomwe ili pansi pano, yomwe imaphatikizapo mitengo yachinyamata yomwe imangobzala kumene. Zowonongeka kale ndi zovuta, mitengo yaing'ono ya magnolia yomwe ili ndi tsamba la masamba ikhoza kufa chifukwa cha infestation. Ndizimenezi ndizofunikira kulamulira mankhwalawa
Mukasankha kulimbana ndi tsamba la magnolia, njira yabwino kwambiri ndi mkuwa wokhudzana ndi fungicide. Komabe, kuti zitha kukhala zothandiza, fungicide ayenera kupopedwa pamphindi yoyenera. Chifukwa fungicides amagwira ntchito monga zotetezera, osati mankhwala, nthawi yoyenera kugwiritsa ntchito nthawiyi isanafike fungus. Izi zimafuna kuti mukhale tcheru ndikupopera mtengo nthawi yomweyo powona zizindikiro zoyamba za tsamba. Kapena, ngati muwona mitengo yofanana m'deralo yoyamba kukhudza tsamba la tsamba, yesetsani kuyamba kupopera mitengo yanu. Ngati mumatenga bowa pachiyambi cha matendawa kapena musanawonekere pamtengo wanu, mumakhala ndi mwayi wokonza kufalikira kwake. Ngati agwiritsidwa mochedwa kwambiri, chithandizo sichingakhale chogwira ntchito.
Kuteteza Fungus Leaf Spot
Mitengo yamakono ya magnolia imatha kukana tsamba, choncho njira yabwino yothetsera ndiyo kusamalira magnolia bwino. Popeza chinyontho chimalimbikitsa kufalikira kwa bowa, ndibwino kupititsa patsogolo kayendetsedwe ka mlengalenga . Izi zikhoza kupindula ndi:
- Kudulira nthambi pa magnolia mitengo yomwe ikukutsana
- Kudulira nthambi za mitengo yoyandikana ndi mitengo kapena zitsamba zomwe zingakhale zikudutsa malo a magnolias
