Mavairasi, mabakiteriya ndi bowa angayambitse matenda osiyanasiyana m'mitengo. Matenda owopsa kwambiri ndiwo omwe tizilombo ta tizilombo ta tizilombo toyambitsa matenda tili ndi mphamvu zowonongeka. Nthawi iliyonse, matenda ofala amasiyana malinga ndi nyengo. Matenda ena amawoneka m'nyengo yamvula, pamene ena amawoneka pamvula.
Khansa
Khansa imayambitsidwa ndi mabakiteriya kapena bowa. Matendawa amakhudza zimayambira ndi nthambi za zomera. Chifukwa cha khansa imafa cambium, yomwe ili pansi pa makungwa a mitengo ndi mitengo. Kawirikawiri khansara imapezeka pamtunda, nthendayi imakula mpaka mphukirayo itamveka, ndipo chigawo cha pamwamba pa chilondacho sichifota. Kawirikawiri, alimi amaluwa ngati zizindikirozi amatengedwa kuti akhale zizindikiro za matenda osiyana siyana (kutentha, mwachitsanzo), ngakhale kuti ali ndi kansa yomwe yafika pamunsi pa mbeu.
Chiphuphu
Matendawa amachititsa kuti phulusa kapena mizu ikhale yovunda ndipo ili ndi tanthauzo lalikulu lomwe likutchulidwa payekha. Maapulo (bowa la mtundu wa Amillaria) ndi matenda oopsa kwambiri a fodya, chifukwa zimakhala zovuta kulimbana nazo, ndipo sizikutha kuthetsa kuthetsa.

Matendawa ali ndi katundu kukula, nthawi zina amajambula tsamba lonse, lomwe limatsogolera ku imfa yake. Chifukwa cha matendawa, zomera zonse zimafa.
Leaf spotting
Matendawa amayamba ndi mabakiteriya ena komanso bowa. Matendawa amaphatikizidwa ndi mabala ofiira kapena imvi, nthawi zambiri ndi m'mphepete mwawo. Tsamba la tsamba la rhododendron limalimbikitsa chitukuko cha mabala a bulauni kapena ofiira, pomwe mbali yoyamba imakhala yofiira. Kuwonjezeka, mawangawo akuphatikizana palimodzi, potero amapanga malo akuluakulu a minofu yakufa. Pambuyo pa kuwonongeka kwakukulu, masamba amafa ndi kutha, omwe amachepetsa kukula kwa mbewu.
Mitengo
Gray nkhungu kapena botrytis bowa akuonedwa ambiri nkhungu bowa. Matendawa amakhudza mitundu yambiri yokongoletsera yomwe imamera yotseka komanso yotseguka. Grey kuvunda kumakhudza kwambiri zimayambira, maluwa, masamba ndi zipatso, zomwe zimachititsa kuwonongeka kwa minofu, kupanga chovala choyera.
Pakalipa powdery mildew
Odziwika kwambiri matenda a munda zomera. Matendawa amadziwika ndi maonekedwe a pamwamba pa pepala la powdery amamverera ngati woyera, pali zosiyana. Izi powdery mildew ali ndi dzina losiyana - spherote.
Kutupa
Gulu lalikulu la matenda a fungal. Mpweya umagunda masamba ndi masamba, omwe amapezeka pamatumba a mtundu wobiriwira kapena wachikasu. Pansikati mwa masamba amakhudzidwa ndi mawonekedwe a mabala ofiira, achikasu, oyera ndi a lalanje. Mtundu wa mabelters umadalira mtundu wa matenda. Zakudya zam'madzi zimatuluka ndipo zimatulutsa zilonda zomwe zimapatsira zomera zina.
Mizu yovunda
Izi ndi magulu akuluakulu a matenda, omwe amawononga maselo a zinyama zamasamba ndikuwapangitsa kukhala ovunda. Zimakhudza maziko ndi mizu ya chomera, choncho imagawidwa mu basal ndi muzu zowola. Nthawi zina zimakhala zovuta kudziwa cholinga cha mbeu.
Kuphulika
Matenda ofala komanso odziwika bwino, opweteka ndi bowa, mabakiteriya, mavairasi. Pa zomera, onse amachita chimodzimodzi, choyamba amachititsa kuti zitsamba, masamba, mphukira, zitha kupha mbewu yonse. Nthawi zina, kuphulika kumawonekera pa nthawi, pali nthawi zomwe zomera zimachira. Imfa ya chomera ndi sitepe yotsiriza ya matendawa.
Mavairasi
Vutoli ndi lingaliro la matenda osiyanasiyana omwe amakhudza chiwerengero cha zomera. Zizindikiro za matenda opatsirana pogonana - kuletsa kukula kwa zomera, kusintha kwa masamba ndi masamba, kuwona, maonekedwe a maluwa ndi masamba, necrosis ya matenda.
