“…In classical phytopathological studies of various pathogens, research begins with the observation of the development of the disease (symptoms and etiological signs). The observations made during the presented studies fully confirmed the earlier findings of various Polish researchers from the last 50 years [ 16 , 18 , 30 , 39 , 40 , 41 , 42 , 43 , 44 , 45 , 46 ]. Similar results have also been obtained outside Poland and even outside Europe [ 4 , 13 , 24 ].…”

“…However, it is clearly emphasized everywhere that this disease is the most dangerous fungal disease of highbush blueberry [ 18 ]. In a 3-year study carried out in 3 locations in the Lublin Voivodship, Szmagara [ 45 ] has identified as many as 20 different fungi occurring in highbush blueberry plantations on the basis of the fungal structures (e.g., pycnidia) produced on shoots, with Godronia constituting 7.4% of all the identified fungi.…”

“…Next, the dishes were incubated under white light at 20 • C (14 h day/10 h night). Colony size measurements were taken 3,5,7,9,12,15,17,19, and 21 days after inoculation. The areas of fungal colonies were calculated using the formula for the area of the ellipse.…”

“…The symptoms of the abovementioned diseases on the stems and shoots can be described as ellipsoidal necrotic spots of a chestnut-brown color with a brighter center and red-purple margins. They are located mainly in the lower parts of one- or two-year-old stems [ 3 , 16 , 17 ].…”

Phenotypic Characterization and Phylogeny of Godronia myrtilli (Anamorph: Topospora myrtilli)—Causal Agent of Godronia Canker on Highbush Blueberry

Godronia canker caused by Godronia myrtilli (Feltgen) J.K. Stone is considered one of the most dangerous diseases of blueberry crops. The purpose of the study was the phenotypic characterization and phylogenetic analysis of this fungus. Infected stems were collected from blueberry crops in the Mazovian, Lublin, and West Pomeranian Voivodships in 2016–2020. Twenty-four Godronia isolates were identified and tested. The isolates were identified on the basis of their morphology and molecular characteristics (PCR). The average conidia size was 9.36 ± 0.81 × 2.45 ± 0.37 µm. The conidia were hyaline, ellipsoid or straight, two-celled, rounded, or terminally pointed. The pathogen growth dynamics were tested on six media: PDA, CMA, MEA, SNA, PCA, and Czapek. The fastest daily growth of fungal isolates was observed on SNA and PCA, and the slowest on CMA and MEA. Pathogen rDNA amplification was performed with ITS1F and ITS4A primers. The obtained DNA sequence of the fungus showed 100% nucleotide similarity to the reference sequence deposited in the GenBank. Molecular characterization of G. myrtilli isolates was performed for the first time in this study.

“…Our country is one of the leading blueberry producers, and in 2021, the harvest was 55.3 thousand tons (GUS, 2021). In recent years, fungal diseases have become an increasing problem in the cultivation of blueberries in Poland, as dieback of stems and shoots caused by fungal pathogens can be particularly damaging, affecting plant health and strongly reducing fruit yield (Szmagara, 2018).…”

Members of the genus Diaporthe are among the most common plant pathogens and cause disease symptoms in a wide variety of hosts. In the present study, six isolates were obtained from necrotic symptoms observed on shoots from diebacks of highbush blueberry plants (Vaccinium corymbosum) in Poland. The isolates showed typical morphology for the genus Diaporthe and were categorized in three morphotypes for further molecular identification. The isolates were identified by sequence analysis of internal transcribed spacer region (ITS) and genes encoding beta‐tubulin (tub2), transcription elongation factor 1 alpha (tef1‐α), calmodulin (cal) and histone H3 (his3). The results revealed that the Diaporthe isolates corresponded to three different species: five isolates to D. eres and one to D. rudis. Pathogenicity tests confirmed the capability of all evaluated Diaporthe isolates to induce similar necrotic symptoms on highbush blueberry shoots as observed under natural conditions. This study is the first description and characterization of Diaporthe species associated with blueberry shoot dieback in Poland.
