“…On the other hand, Commelina benghalensis and Glycine max were susceptible to all isolates. These results are similar to those of Rennberger and Keinath [ 11 ] and Aumentado and Balendres [ 12 ], in which Parammyrothecium species were able to infect original and non-original hosts within the same family (host shift ability) and different families (host jump ability).…”

“…Rennberger and Keinath [ 11 ] isolated P. foliicola and P. humicola from watermelon and two other cucurbits and confirmed their pathogenicity on watermelons, tomatoes, and southern peas. Aumentado and Balendres [ 12 ] reported P. foliicola causing crater rot in eggplant and 45 plant species from 21 plant families and were tested for the pathogenicity on detached fruit or leaf assays. Furthermore, P. foliicola is pathogenic to cucumber seedlings and watermelon, causing stem canker [ 13 ].…”

Species of Paramyrothecium that are reported as plant pathogens and cause leaf spot or leaf blight have been reported on many commercial crops worldwide. In 2019, during a survey of fungi causing leaf spots on plants in Chiang Mai and Mae Hong Son provinces, northern Thailand, 16 isolates from 14 host species across nine plant families were collected. A new species Paramyrothecium vignicola sp. nov. was identified based on morphology and concatenated (ITS, cmdA, rpb2, and tub2) phylogeny. Further, P. breviseta and P. foliicola represented novel geographic records to Thailand, while P. eichhorniae represented a novel host record (Psophocarpus sp., Centrosema sp., Aristolochia sp.). These species were confirmed to be the causal agents of the leaf spot disease through pathogenicity assay. Furthermore, cross pathogenicity tests on Coffea arabica L., Commelina benghalensis L., Glycine max (L.) Merr., and Dieffenbachia seguine (Jacq.) Schott revealed multiple host ranges for these pathogens. Further research is required into the host–pathogen relationship of Paramyrothecium species that cause leaf spot and their management. Biotic and abiotic stresses caused by climate change may affect plant health and disease susceptibility. Hence, proper identification and monitoring of fungal communities in the environment are important to understand emerging diseases and for implementation of disease management strategies.

“…Detached leaf assays were performed following the method used by Aumentado and Balendres (2022b) to determine the pathogenicity of Corynespora cassiicola MBEPFR02 to 36 plant species representing 10 plant families (Table 1). Leaves were sterilized by soaking in 10% sodium hypochlorite solution, washed three times with sterilized distilled water, and air‐dried.…”

Emerging fungal pathogens could bring irreversible damage to economically important plant species resulting in yield losses. One method of control of plant diseases is crop rotation, whereby the main cultivated crop is rotated with other crops. However, for crop rotation to be successful, the alternative crop must be a non-susceptible or non-host plant of the pathogen. In January 2021, for the first time, Corynespora cassiicola was reported to cause leaf spots and fruit rot in eggplant (Solanum melongena) in the Philippines. This study investigated the potential host range of newly reported C. cassiicola in controlled, repeated pathogenicity assays. Of the 36 plant species (19 plant families) assayed for leaf infection, 26 and 23 plant species were pathogenic to C. cassiicola in wounded and unwounded conditions, respectively. Of the 27 plant species (13 plant families) assayed for fruit/head/bulb/tuber infection, 16 and 6 were susceptible to C. cassiicola in wounded and unwounded conditions, respectively. Among all plant species assayed, mango, tomato, and beans were considered very susceptible as infection occurred in both leaves and fruits and wounded and unwounded treatments. The related species, tomato and pepper, were also susceptible to diseases caused by C. cassiicola. This is the first report of the pathogenicity of the C. cassiicola Philippine strain to various plant species assessed in controlled conditions.

“…Paramyrothecium foliicola has been reported attacking different unrelated hosts in several countries. Recent examples are: on eggplant in the Philippines (Aumentado and Balendres 2022), on watermelon in Mexico (Cruz-Lachica et al 2021), and tomato in China (Huo et al 2022). Besides that, cross-inoculations of P. foliicola have indicated that this species is a polyphagous fungal pathogen capable of infecting unrelated crop plants such as lettuce, coffee, and soybean (Matić et al 2019;Withee et al 2022).…”
