Trachemicomy wilt
Chizindikiro choyamba chiri chiyambi cha njira yovunda mizu. Nkhungu zimatseka njira yopititsira zakudya, zomwe zimapangitsa kuti mitsempha ya maluwa ikhale yovuta.
Rhododendron imatembenuka bulauni ndi dries, masamba amaphimbidwa ndi petioles, ndipo imvi yoyera mycelium imapezeka pa makungwa. Muzuwo umamwalira pang'ono. Zotsalira za zomera zimapitiriza kusunga kachilomboka.
Ngati chitsamba chikudwala, nkofunika kuchepetsa malo omwe ali ndi kachilombo ndikuwotchera mwamsanga. Njira yonse yopanga ndi Bordeaux madzi. Kupewa kumachitidwa ndi kupopera mbewu mankhwalawa tchire ndi kuthirira mizu yawo ndi 0.2% yankho la kukonzekera "Fundazol". 
Phytophthora zowola
Zovuta zowonjezereka zowola zimachitika chifukwa chotsekedwa kwa rhododendron kapena osalidwa bwino. Kuwonjezera apo, n'zotheka kubweretsa phytophthora kuvunda kumunda chiwembu pamodzi ndi shrub yosawonongeka yomwe inagulidwa kumera. Matendawa amayamba kufota masamba popanda kuthekera kwachira.
Muzuwo umakhala bulauni ndi kuvunda. Yambani kutembenuza nthambi za chikasu, ndiyeno rhododendron yonse. Muzu wa mizu ndi tsinde la zimayambira zili ndi mabala a bulauni ndi nsalu zofiira, zomwe zimakhala zakuda kwambiri za fungus spores. Chitsamba chimatha ndipo chimadontha, koma zitsamba zake ndi nthaka zimateteza matendawa.
Pa nthawi yoyamba ya mankhwalawa, m'pofunika kuyamba mankhwala oyamba ndi Bordeaux matope, "Quadris" kapena "Readzole" 0.2%. Zomera zowonjezereka ziyenera kutenthedwa ndi mizu ndi njira yokonza yathanzi baka. 
Khansa ya bakiteriya
Khansara ya bakiteriya imawoneka mwa kupanga mapangidwe ozungulira mozungulira mizu ndi mizu ya mizu ya kukula kwakukulu. Mapangidwe awa amakhala owala kwambiri ndi nthawi.
Chitsamba chimachepa kukula ndi kutaya mphamvu ya maluwa. Kukula kwina pamodzi ndi mizu kumayamba kuvunda, mbewu imamwalira, koma zitsamba zake zimapitiriza kusunga matenda.
Ndikofunikira! Mitundu ina imatha kutenga kachilomboka kudzera mukubzala.
Mofanana ndi zovuta kuchepetsa, tchire kusonyeza zizindikiro zoyambirira ziyenera kuchitidwa nthawi zonse ndi Bordeaux madzi kapena mankhwala ena ofanana. Ngati zowonongeka, perekani chomera pamodzi ndi mizu. 
Grey ndi zina zowola
Rhododendron ingakhudze mitundu yovunda yosiyanasiyana:
- imvi
- mbande ndi mbande zazing'ono;
- mphukira;
- mizu;
- choyera choyera;
- akufa mphukira.
Kuphimba pamwamba pang'onopang'ono kumauma ndi kuyamba kutha. Pamakhala chinyezi, mbali zina zachitsamba zomwe zimakhudzidwa ndi necrosis zimakhala ndi utoto wofiira wamtundu wofiira. Patapita kanthawi, kuyanika kwa mycelium kwodzala ndi bulauni yotchedwa sclerotia.
Mukudziwa? Ku Nepal, rhododendron imapanga madzi, tiyi, komanso imakola maluwa ake.
N'zotheka kupirira zowola pokhapokha mutadula malo okhudzidwa a rhododendron. Kuchiza chithandizo, perekani chomeracho ndi 0.2% yankho la kukonzekera "Fundazol" ndi kutsanulira mzere woyandikana nawo.
Mbeu zowola ndi mbande zazing'ono pakuti rhododendron imayamba ndi kufota ndi kutha ndi imfa. Nkhumba zoyera za bowa kapena zofiira zofiira pamasamba ake, ndipo pamwamba pake zimadzaza ndi ulusi wofanana ndi makobu.
Akuwombera, amene anayamba kufa, kuwaza ndi wosweka makala kapena ufa wa mankhwala "Fundazol." Kuonjezera apo, pofuna cholinga cha prophylaxis, n'zotheka kuchiza ndi ndondomeko ya 0.2% yokonzekera "Readzol".
Mitengo yowola Mphukira imasanduka bulauni ndikufa, kenako mycelium imakula kukhala nthambi. Kuchepetsa chitukuko cha matendawa pochotsa mdima wakuda ndi mphukira youma. Pamene chomera chikhala ndi moyo m'nyengo ya kukula, masabata awiri aliwonse amathira mankhwala osokoneza bongo.
Kudya mphukira imayambitsa zitsamba zikukula mumthunzi. Mitengo yam'mwamba pamwamba pa chitsamba sichidzaphuka. Mmalo mwake, mtundu wawo udzakhala wofiira ndipo njira yakufa idzayamba. Potsatila, masambawo ayamba kupindika, kupeza mtundu wofiira ndi wouma. Ndi kugonjetsedwa kwakukulu mbewuyo idzafa. Matendawa amayamba ndi kubowola masamba pa mphukira zina. Kenako adzayamba kuuma, kenako kuthawa konse kudzafa.
Kupirira imfa ya mphukira mwa kuwotcha masamba omwe anakhudzidwa ndi kuwombera. Kachilombo kamene kamangoyamba, imayenera kuyamba mankhwala (omwe ali ndi milungu iwiri) ndikukonzekera zamkuwa.
Vuto loyambira limakhudza mizu ndi zimayambira pansi. Koma choyamba, masambawo amatha ndipo amauma popanda chifukwa. Kenaka, impsozo zimakhala zofiirira komanso zimafa. Posakhalitsa imfa ya rhododendron, mizu imakhala yofiirira ndi yovunda.
Pofuna kuthana ndi matendawa, nkofunika kuwotcha malo okhudzidwa ndi zomera kapena odwala onse. N'zotheka kuteteza khola kumtunda kuvunda. Pitirizani kukhala ndi acidity panthaka yomwe ili yofunikira kwambiri kuti muyambe maphunziro anu, ndipo tsatirani malamulo owetsera madzi. 
Mdima wonyezimira wouma umathamanga kuzungulira muzu wazu wa mbewu ndikuwoneka ngati mphete yonyezimira. Chilondachi chimayambitsidwa ndi bowa wotchuka, uchi wowawa kwambiri, womwe ndi bowa wake womwe umamera m'ziphuphu zochepa. Chifukwa chake, chitsamba chimamwalira. Matendawa amakula kwambiri.
Chomera chokhudzidwacho chiyenera kufulidwa ndi kutenthedwa, ndipo tchire pafupi ndi izo tiyenera kuziika. 
Ndikofunikira! Kuwotchera kuyenera kuchitidwa kuti mulch asaphimbe mutu wa chitsamba.
Matenda a Sera
Ndikhoza kuyambitsa matenda a sera ndi mitundu yosiyanasiyana ya bowa, zomwe ziri: 
- Chifukwa pang'ono deformation ndi makulidwe a masamba. Iwo ali ndi zikopa zazikulu zozungulira zofiira kapena zofiira zofiira. Kumalo a necrosis, sera ya sera imapezeka kuchokera ku spores. Zotsatira zake, mawanga amakhala owuma ndi osweka.
