During disease surveys of Angelica acutiloba plants in Korea, leaf spot symptoms were observed a field Andong July 2019, and stem rot vinyl greenhouses Yangpyeong April 2020. Incidence the ranged from 10 to 20% 5 30%, respectively. Morphological cultural characteristics fungal isolates fitted into those genus Phoma. Molecular phylogenetic analyses two single-spore using concatenated sequences LSU, ITS, TUB2, RPB2 genes authenticated an independent cluster other Didymella (anamorph: Phoma)...

During a disease survey in October 2019, leaf spot symptoms with yellow halo were observed on Korean angelica (Anglica gigas) plants grown fields Pyeongchang, Gangwon Province, Korea. Incidence of diseased leaves the investigated ranged from 10% to 60%. Morphological and cultural characteristics two single-spore isolates lesions indicated that they belonged genus Didymella. Molecular phylogenetic analyses using combined sequences LSU, ITS, TUB2, RPB2 regions showed distinct clustering other...

In July 2022 and 2023, black mold symptoms were observed sporadically on fruits of sweet pepper (<i>Capsicum annuum</i>) plants grown in a greenhouse located Suwon, Korea. The incidence the was 5−24% (average 14.8%) variety SP-504 (yellow elongate type) 1−8% 5%) SP-505 (red round investigated. Four single-conidium isolates <i>Alternaria</i> sp. obtained from diseased identified as <i>Alternaria alternata</i> based morphological characteristics molecular...

During disease surveys in 2021 and 2022, outbreaks of leaf spot were observed East Asian hogweed (Heracleum moellendorffii) plants fields located Pyeongchang Yeongwol, Gangwon Province, Korea. The incidence the ranged from 2% to 50%. Based on morphological cultural characteristics, four single-conidium fungal isolates symptoms identified as Phoma sp. phylogenetic analyses based combined sequences genes (LSU, ITS, TUB2, RPB2) indicated that clustered very closely with Didymella acutilobae....

Unusual symptoms of Sclerotinia rot were observed in stringy stonecrop (Sedum sarmentosum) plants cultivated vinyl greenhouses Icheon, Korea, during a disease survey conducted March 2024. The characterized as soft stems and leaves at or above the soil line early stage. In late stage, most diseased collapsed rotted with white to grayish brown mycelia. Occasionally, black, spherical irregular, small sclerotia formed on plants. occurred 1‒3% three out 20 surveyed greenhouses. Three isolates sp....

Fruit rot symptoms were observed in papaya trees (Carica papaya) grown a greenhouse Gokseong, Korea, during disease surveys 2021 and 2022. The developed from the fruit ends, white hyphae grew on lesions. incidence of diseased fruits investigated was 0.5–1.0%. Six single-conidium isolates obtained identified as Fusarium sp. based their morphological characteristics. Phylogenetic analysis revealed that divided into two distinct groups. One group consisting clustered with bostrycoides, while...

In December 2020, stem and leaf rot symptoms in small-fruited tomato (Solanum lycopersicum) plants were observed a farmer’s vinyl greenhouse located Pyeongtaek, Gyeonggi Province, Korea. The incidence of diseased the was 2‒6%. Seven single-spore isolates Phoma sp. obtained from stems leaves. All identified as Boeremia linicola based on cultural, morphological molecular characteristics. Two B. tested for pathogenicity leaves large-fruited using artificial inoculation. caused inoculated...

During disease surveys from 2019 to 2021, the authors frequently encountered leaf spot symptoms on Fischer’s ragwort plants growing at fields six locations of Gangwon Province, Korea. The displayed brown dark brown, circular or irregular spots plant leaves. revealed 1–90% diseased leaves plants. Phoma sp. was dominantly isolated lesions. Seven single-spore isolates fungus were selected and identified as Didymella ligulariae by investigation their cultural, morphological, molecular...

In May 2020, we surveyed disease occurrence on vegetables grown in Seosan area, Korea. During the survey, white rot symptoms were observed Korean wild chive (<i>Allium monanthum</i>) plants growing fields. The occurred mainly seed bulb-producing fields of crop. above ground parts diseased displayed premature yellowing and dying older leaves stunting plants. bulbs roots turned black rotted. a range 1–60% four eight surveyed. Three isolates <i>Sclerotium</i> sp....

During a disease survey conducted in April 2022, we observed severe gray mold symptoms on inflorescences of mango trees (<i>Mangifera indica</i>) grown vinyl greenhouse Jeju, Korea. The occurred the flowers and peduncles, which lot molds were formed. incidence ranged from 10% to 40%. Three fungal isolates obtained lesions identified as <i>Botrytis cinerea</i> based their morphological characteristics phylogenetic analysis. All <i>B. tested for pathogenicity...

In 2020 and 2021, we surveyed diseases of three-leaf ladybell (<i>Adenophora triphylla</i>) plants grown in fields at two locations Korea. During the disease surveys, severe leaf rot symptoms were observed on young Hongseong, stem adult Cheolwon. The incidence was 5‒60%, that 1‒10%. We obtained 6 fungal isolates each from lesions lesions. All morphologically identified as <i>Rhizoctonia solani</i>. Anastomosis test investigation cultural features revealed corresponded...
