I-Rhododendron iyingxenye yezitshalo zokuhlobisa, ngakho-ke zihlaselwa yizinambuzane nezifo ezihlukahlukene. Ama-Evergreen, atshalwe elangeni, avame ukuhlaselwa yizifo kunabase-penumbra. Ubuchwepheshe obufanele bezolimo bukhulisa ukuphikiswa kwesitshalo, kodwa usongo lisekhona. Kulesi sihloko, sizocubungula ukuthi kungani amaqabunga e-rhododendron aphepheka masinyane, amafihlethi amnyama noma amaqabunga aphelile, kanye nezifo eziyinhloko ezihlotshaniswa nezihlahla ezihlobisa.
Trachemicomy wilt
Isibonakaliso sokuqala siyi ukuqala kwenqubo yokubopha uhlelo lwempande. Izikhunta zivimba indlela eya ezakhiweni, ngenxa yalokho isimiso sezinthambo zesitshalo sihlupheka.
I-Rhododendron iphenduka isundu futhi imile, amaqabunga ahlanganiswe nama-petioles, futhi i-mycelium emhlophe-emhlophe ivela emagxolo. Impande kancane ifa. Izinsalela zalesi sitshalo ziyaqhubeka nokugcina ukutheleleka.
Uma isihlahla sigula, kuyadingeka ukunciphisa izindawo ezinesifo bese usishisa ngaphandle kokulibala. Hlela yonke isitshalo nge Bordeaux liquid. Ukuvimbela kwenziwa ngokusitshala izihlahla futhi ukuchelela indawo yazo yezimpande ngesisombululo se-0.2% sokulungiselela "Fundazol". 
Phytophthora ukubola
Ukulimala kwesikhathi eside kwenzeka ngenxa yokuvalwa kwe-rhododendron noma ukugeleza okungekho emthethweni. Ngaphezu kwalokho, kungenzeka ukuletha i-phytophthora ukulima esihlalweni segadini kanye nesibhakabhaka esingenampilo esithengiwe kumanyolo. Lesi sifo siqala ukuhluma amahlamvu ngaphandle kokuhlelwa kwawo.
Umsuka uba mnyama futhi ubola. Qala ukuvula amagatsha aphuzi, bese u-rhododendron wonke. I-collar yezimpande kanye nesisekelo seziqu zimbozwa amabala aluhlaza ngombala obomvu, lapho kugcwele khona ama-fungus spores amnyama. Isihlahla sishaya futhi soma, kodwa izinsalela zalo kanye nomhlabathi nxazonke zigcina igciwane.
Esikhathini sokuqala se-lesion nge-rhododendron, kubalulekile ukuqala ukwelashwa okuvamile ne-Bordeaux mortar, "Quadris" noma "Fundazole" 0.2%. Izitshalo ezinzima kufanele zishiswe ngezimpande kanye nesondlo sokuvimbela izihlahla eziphilile. 
Umdlavuza wesibindi
Umdlavuza webhaktheriya ubonakala ngokubunjwa kwama-bulges azungeze nxazonke ezimpandeni nasempandeni lempande yobukhulu obukhulu. Lezi zakhiwo ziba mnyama futhi zinzima ngokuhamba kwesikhathi.
Isihlahla sikhula ekukhuleni futhi silahlekelwa amandla okuzimbali. Ukukhula okuqhubekayo kanye nentamo yempande kuqala ukubola, lesi sitshalo sifa, kodwa izinsalela zayo ziyaqhubeka nokugcina isifo.
Kubalulekile! Amanye ama-rhododendron angenwa igciwane ngokusebenzisa izinto zokutshala.
Njengazo zonke izinto ezibucayi, izihlahla ezikhombisa izimpawu zokuqala kufanele ziphathwe njalo nge-Bordeaux liquid noma esinye isidakamizwa esifanayo. Uma kwenzeka umonakalo omkhulu, vutha isitshalo kanye nesistimu yezimpande. 
Grey nokunye ukubola
I-Rhododendron ingathinta ezihlukahlukene zokubola:
- grey
- izithombo kanye nezithombo ezincane;
- ihlumela;
- impande;
- umhlophe owomile;
- bebulawa amahlumela.
Ukugqoka okuqhamuka kancane kancane kuyoma futhi kuqala ukuqhuma. Ngomswakama ophezulu, izingxenye zasemahlathini ezithintekayo yi-necrosis zimbozwe ngengubo ephuzi ephuzi epholile. Ngemva kwesikhashana, ukumisa i-mycelium kugcwele i-sclerotia ebomvu.
Uyazi? E-Nepal, i-rhododendron yenza ijusi, itiye, futhi ikhekhe ngisho nezimbali zayo.
Kungenzeka ukubhekana nokubola kuphela ngokusika izindawo ezithintekayo ze-rhododendron. Ukuze uthole ukwelashwa kwe-prophylactic, faka lesi sitshalo ngesisombululo se-0.2% sokulungiselela "Fundazol" futhi uthele indawo yempande nayo.
Izithombo ezivuthiwe nezithombo ezincane ngoba i-rhododendron iqala ngokubola futhi iphela ngokufa. Izinhlamvu ezimhlophe ze-fungi noma amafreyimu ama-brown afaka emaqabunga awo, futhi ubuso bumbozwe ngemicu efana namacweb.
Amahlumela, aqala ukufa, afafaza amalahle achotshoziwe noma i-powder yomuthi "Fundazol." Ngaphezu kwalokho, ngenhloso ye-prophylaxis, kungenzeka ukwelapha ngesisombululo se-0.2% sokulungiselela "Fundazol".
Ama-Buds abola Ifihlekile iphenduka isundu bese ifa, emva kwalokho i-mycelium ikhula ibe ngamagatsha. Ukunciphisa ukuthuthukiswa kwesifo ngokususa amafihlethi omnyama namahlumela omile. Ngenkathi lesi sitshalo siphila ngesikhathi sokukhula, njalo ngemva kwamasonto amabili siyifaka ngezidakamizwa ezifaka ithusi.
Ukubulala amahlumela usongela izihlahla ezikhula emthunzini. Ama-buds phezulu esihlahleni ngeke aqhakaze. Esikhundleni salokho, umbala wabo uzoba mnyama futhi inqubo yokufa izoqala. Ukulandela, amaqabunga azoqala ukugoqa, athole umbala obomvu futhi owomile. Ngokunqotshwa okunamandla lesi sitshalo sizofa. Lesi sifo singaqala ngokugaya amaqabunga kwezinye amahlumela. Khona-ke zizoqala ukoma, emva kwalokho lonke ukuphunyuka kuzofa.
Ukuze ubhekane nokushona kwamahlumela ngokushisa amahlamvu abathintekayo futhi uhlume. Uma nje i-rhododendron iphela, kufanele iqale ukwelashwa kwayo njalo (njalo ngemva kwamasonto amabili) ngamalungiselelo ensimbi.

Kubalulekile! Ukufakelwa kwezitshalo kufanele kwenziwe ukuze imboketshe ingagubuli intamo yomhlanga.
Isifo se-Wax
Ngingavusa isifo se-wax ngezinhlobo eziningana zefungi, okuyizi: 
- Yenza ushintsho oluncane ngokuqina kwamaqabunga. Ambozwe ama-patches amakhulu obomvu obomvu noma obomvu noma ahlukaniswe. Endaweni ye-necrosis, i-wax bloom ivela ezinhlamvu. Ngenxa yalokho, amabala ayomile futhi aqhekeke.

Isifo se-rhododendron, esimelelwe emfanekisweni, sibonakala ngokubunjwa kwamagciwane omzimba we-fungal emaceleni amabala, ngakho-ke, uphathwa ngokunqamula izindawo ezithintekile nokuphatha i-shrub ne-Bordeaux noma i-Camulus. 
Kubalulekile! Ukutshala izitshalo ngamalungiselelo ezethusi emswakama ophezulu kusongela amahlamvu kanye namahlumela ngokushisa.I-Phylocystic stain ihlolwe njengeqabunga. Isibonakaliso sesimpawu senzeke ngamachashazi amakhulu okuzungeza nomngcele obomvu. Ama-black sporangia aqala ukuphuma kuwo. Ngaphezu kwalokho amahlamvu aphela.
Ukufakela indawo kungase kube mnyama kuye ngokuthi uhlobo lwe-pathogen. Ngokuhamba kwesikhathi, ukunqotshwa kukhanya, kuphazamisa futhi kugubha. Kulesi simo, kubalulekile ukunciphisa izingxenye ezithintekile futhi uphathe isihlahla neBordeaux liquid noma Camulus.
