“…simplicissimum on the basis of morphological criteria using Pitt (1979) are recorded from onion in Pakistan (Ibatsam et al, 2012). Penicillium brasilianum is recorded on onion in Korea, and was distinguished from P. simplicissimum by multi-gene topology (Sang et al, 2014). Our assay for P. polonicum obtained the same result as in Dugan et al (2014), except that in 2014 the isolate used (not identical to the isolate here but also from seed of onion cultivar al., 2014), Turkey (Çakir and Maden, 2015), and from each of our hosts in Dugan et al (2014).…”

“…Botrytis sp., Fusarium oxysporum, Penicillium sp., Aspergillus awamori, Rhizopus oryzae, and Alternaria sp. are well known to cause decay during onion storage in Korea [4,5]. However, the application of agrochemical fungicides is limited because of public concerns over the human health and environmental risks over the agrochemical residues.…”

Corona discharge air plasma (CDAP) is a nonthermal decontamination technology which is generating antimicrobial agents such as photons, electrons, positively and negatively charged ions, atoms, and free radicals. We investigated the effect of a corona discharge under atmospheric pressure on the sterilization of postharvest fungal pathogens on onion. The main antimicrobial reactive substance generated by CDAP was O3. The active species such as nitric oxide (NO) and nitric dioxide (NO2) were nearly detected in this experiment. CDAP treatment revealed different isolation frequencies depending on postharvest pathogens from diseased onions, showing less isolation frequency of Fusarium spp. and Alternaria sp. than that of Botrytis spp. when compared with untreatment onions during 10-month cold storage. CDAP treatment at 2∼2.6 ppm of O3 slightly stimulated the mycelial growth of Alternaria sp., while the treatment at 20∼24 ppm of O3 gradually inhibited mycelial growth by treatment time. However, Botrytis sp. showed different patterns of mycelial growth with CDAP treatment. Less than 4 hours’ treatment of CDAP slightly inhibited the mycelial growth of Botrytis sp., while 8 hours’ treatment of CDAP slightly stimulated the mycelial growth of Botrytis sp. not depending on the concentration of O3. The inhibitory effect of CDAP on the conidial germination of Alternaria sp. and Botrytis sp. was examined with treatment time and intensity of CDAP. The conidial germination of Alternaria sp. treated with CDAP at the concentration of 13.7∼14.4 ppm of O3 was strongly inhibited by time, showing y = 2.66x2 − 85.139x + 4.88 and R2 = 0.98. When the conidia of Alternaria sp. were exposed for 2 hours with varying plasma O3 concentration, the conidial germination was strongly inhibited as the concentration of O3 increases, showing y = −0.09x2 + 6.905x − 0.764 and R2 = 0.95. The conidia of Botrytis sp. also showed similar patterns to CDAP. The inhibitory effect of CDAP on the germination of postharvest pathogens depends on treatment time and O3 concentration.

“…As new species are still being described and new host records published (e.g., Strausbaugh & Dugan 2017, Oh & al. 2015, Sang & al. 2014, there is a need for a catalog of names for Penicillium species causing blue mold diseases of bulb and root crops that also cites the literature on hosts and indicates how isolates were identified.…”

Accuracy in assigning specific epithets to Penicillium isolates documented as agents of blue mold of edible and ornamental bulb, root, and tuber crops is highly variable-with methods ranging from appropriate (recent morpho-cultural criteria, metabolite production, DNA sequences), to plausible (older morpho-cultural criteria from monographs), to suspect (unspecified methods, identification via inappropriate literature). We provide a catalogue appropriate for plausibly assigned names accompanied by authorities, references, host distribution, and identification methodology. Names are categorized according to (i) segregates of P. corymbiferum (i.e., names in P. subg. Penicillium) and taxa in P. ser. Corymbifera associated with Liliaceae s.l.; (ii) taxa in P. subg. Penicillium other than P. ser. Corymbifera associated with Liliaceae s.l.; (iii) taxa other than P. subg. Penicillium associated with Liliaceae s.l.; (iv) associates of Beta vulgaris (beets and sugar beets); and (v) associates of mostly tropical or subtropical roots and tubers. Ambiguities or deficiencies in assignment of certain specific epithets are noted.
