Ukwakheka kugxile emaqabungeni amaningana e-dogwood a-elliptical ahlelwe eceleni kwegatsha elincane, elinokhuni. Amaqabunga aluhlaza kakhulu kodwa abonisa izimpawu ezisabalele zokutheleleka ngesimo sezilonda ezingamile ngendlela engajwayelekile, ezinsundu ngokumnyama kuya kokunsomi ezisakazeke ebusweni bawo. Iqabunga ngalinye libonisa amazinga ahlukahlukene omonakalo: amanye anamabala amancane, ahlukanisiwe, kanti amanye abonisa i-necrosis enkulu ebangela ukunsundu nokugoba emaphethelweni. Izicubu ezinesifo zibonakala zicwile futhi ziqhekekile, zihluke kakhulu nezingxenye eziluhlaza ezisaphila zamaqabunga.
Igatsha ngokwalo lembula izimpawu zokuqala zokufa, ezibonakala ngesihloko esimnyama, esishwabene kancane lapho ukufa kwezicubu sekuqalile khona. Imifantu emincane ibonakala ezingxenyeni zegxolo, okubonisa ukuthi isikhunta sesingene ezicutshini zemithambo yegazi ngaphansi. Lezi zimpawu ezibonakalayo ziyisici sokutheleleka kwe-anthracnose okuthuthukile, lapho kokubili amaqabunga neziqu ezincane zithinteka khona, okuvame ukuholela ekususweni kwamaqabunga noma ekufeni kwegatsha.

Lokhu kujula kwensimu okungajulile kugcizelela umehluko phakathi kwezinto zezitshalo ezinempilo nezigulayo, okwenza amabala kanye nokushintsha kombala kubonakale kakhulu. Ukukhanya kuyasabalala futhi kungokwemvelo, kugwema ukugqama okubukhali ngenkathi kwembula ukuthungwa okucashile kwemithambo yamaqabunga kanye nezicubu ze-epidermal. Imithambo ihlala icacile kwamanye amaqabunga angonakalanga kangako, igijima ngendlela ejwayelekile yokwakheka kwe-arcuate ibheke esicongweni seqabunga. Nokho, emaqabungeni athinteke kakhulu, indawo yokutshala ifihlwe kancane yizilonda zesikhunta kanye ne-necrosis esakazekayo.
Imibala iyonke ishintsha kusuka koluhlaza okotshani okusha kuya konsundu ojulile, o-orenji, kanye nomnyama, okubonisa ukuqhubeka okuvamile komonakalo we-anthracnose njengoba isikhunta siphazamisa i-chlorophyll futhi sibangela ukuwa kwamangqamuzana.
