“…Neocosmospora falciformis (Carrión) Summerb. & Schroers has been linked to decay in several plant species [21][22][23][24][25] and to wilt and root rot of muskmelon in Spain [26]. Another member of the complex is Neocosmospora keratoplastica Geiser, O'Donnell, Short & Zhang, which also affects cucurbits by causing rotting and root rot [27].…”

The cliff rose (Armeria maritima), like other halophytes, has a phenolics-based antioxidant system that allows it to grow in saline habitats. Provided that antioxidant properties are usually accompanied by antimicrobial activity, in this study we investigated the phytochemicals present in a hydromethanolic extract of A. maritima flowers and explored its antifungal potential. The main phytocompounds, identified by gas chromatography–mass spectrometry, were: hexadecanoic acid, octadecanoic acid, 9-octadecenoic acid, 3-(3,4-dihydroxy-phenyl)-acrylic acid ethyl ester, and benzeneacetaldehyde. The antifungal activity of the extract and its main constituents—alone and in combination with chitosan oligomers—was tested against six pathogenic taxa associated with soil-borne diseases of plant hosts in the family Cucurbitaceae: Fusarium equiseti, F. oxysporum f. sp. niveum, Macrophomina phaseolina, Neocosmospora falciformis, N. keratoplastica, and Sclerotinia sclerotiorum. In in vitro tests, EC90 effective concentrations in the 166−865 μg·mL−1 range were obtained for the chitosan oligomers–A. maritima extract conjugate complexes, lower than those obtained for fosetyl-Al and azoxystrobin synthetic fungicides tested for comparison purposes, and even outperforming mancozeb against F. equiseti. In ex situ tests against S. sclerotiorum conducted on artificially inoculated cucumber slices, full protection was achieved at a dose of 250 μg·mL−1. Thus, the reported results support the valorization of A. maritima as a source of biorationals for Cucurbitaceae pathogens protection, suitable for both organic and conventional agriculture.

“…Furthermore, Allium species are susceptible to Fusarium. Many Fusarium species could cause Allium species plant rot, such as F. solani [ 49 ], F. proliferatum [ 50 ], and F. falciforme [ 51 ], etc. However, PAT treatment could inhibit the growth of the fungal species pathogenic to plants and humans, which would maintain the quality and guarantee the food safety of A. mongolicum .…”

Allium mongolicum Regel (A. mongolicum) is a healthy edible plant but highly perishable with a short shelf life of 1–2 d. Modified atmosphere packaging (MAP) could inhibit the postharvest senescence and decay of the vegetables. Thus, the aim of this study was to apply MAP with different gas permeabilities to the storage of A. mongolicum and evaluate its effects on maintaining microbial communities and the postharvest quality of A. mongolicum. The results showed that polypropylene/poly(butylene adipate-co-terephthalate) (PP/PBAT, abbreviated as PAT) MAP was suitable for the storage of A. mongolicum by establishing an optimal atmosphere of 0.5–0.6% O2 and 6.2–7.1% CO2 in the bag. It could delay the postharvest senescence of A. mongolicum and maintain its quality by slowing down its respiration rate and weight loss, reducing cell membrane permeability and lipid peroxidation, maintaining the cell wall, and reducing infection and the growth of microorganisms. However, A. mongolicum in HPT was more perishable than that in PAT during storage. Pseudomonas was found to be the main spoilage bacteria, and they could also be effectively inhibited by PAT-MAP. The next-generation sequencing results also showed the growth of Escherichia-Shigella, Clostridium sensu stricto 1, Streptococcus, Aureobasidium, Didymella, and Fusarium, responsible for A. mongolicum decay or human disease, was well inhibited by PAT-MAP. The results suggested that PAT-MAP could be used to maintain microbial diversity and the postharvest quality of A. mongolicum under cold storage conditions. It provided a feasible solution for the preservation, food quality, and safety control of A. mongolicum.

Four members of Fusarium solani species complex (FSSC), F. cucurbiticola, F. petroliphilum, F. falciforme and F. keratoplasticum, cause foot, crown, stem and fruit rot in cucurbits. Although previous studies revealed that F. cucurbiticola was the pathogen causing crown and fruit rot in Taiwan melons, these are unreliable in assessing FSSC infection in cucurbits in Taiwan. We collected 47 FSSC isolates from the stem or fruit rot of bitter gourd, cucumber, luffa, melon and pumpkin, and three FSSC isolates from pumpkin seeds. Eleven pumpkin fruit rot isolates and two pumpkin seed isolates could not infect cucurbit seedlings. Luffa seedlings were tolerant to most FSSC isolates. None of the FSSC isolates could infect cucumber fruits and showed variable virulence in different cucurbit fruits. In addition, only certain FSSC isolates could be amplified by specific primers for F. cucurbiticola and F. petroliphilum. Multilocus sequence typing analyses separated FSSC isolates from the stem or fruit rot or seeds into three molecular groups with high bootstrap values: Group I isolates were F. petroliphilum (FSSC1), Group II isolates were F. solani‐melongenae (FSSC 21) and Group III isolates were F. falciforme (FSSC 3+4). The FSSC isolates amplified by specific primers for race 2 belonged to F. petroliphilum; however, the FSSC isolates amplified by specific primers for race 1 were not F. cucurbiticola. To our knowledge, the three species of the FSSC are novel causative agents in Taiwan.
