Study identified for the very first time two pathogens reported to lead to illness in sweet potato, and JPH203 dihydrochloride pathogenicity tests confirmed their disease-producing capacity. P. rotoruae was discovered and described as a brand new species in New Zealand [42], as well as the Republic of Korea is the second country exactly where this fungal species has been discovered. Postharvest ailments are brought on by numerous components, which include low pH, moisture content material, nutritional composition, improper handling, and management of storage roots for the duration of harvest, transport, and advertising. Improper handling causes wounds in storage roots and enables pathogens to enter, as a result infecting the storage roots. Fusarium spp., M. phaseolina, and many other postharvest pathogens enter in such a way [50]. Infested sweet potatoes can cause really FAUC 365 Technical Information serious health difficulties, particularly mold pathogens which includes Aspergillus spp. and Penicillium spp., which make mycotoxins that could be lethal to humans [50]. For that reason, appropriate handling of sweet potato cultivation at the same time as investigation of doable biocontrol agents and techniques are necessary to minimize the fungus-mediated infections following harvest. Different species of Trichoderma happen to be applied for postharvest biocontrol agents in crops for instance papayas, strawberries, tomatoes, apples, pears, and bananas. Three Trichoderma species, T. asperellum, T. viride, and T. harzianum, showed strong antagonistic activities against various fungal pathogens [51]. The biocontrol agents Trichoderma spp. use several mechanisms against pathogens, such as production of antifungal compounds, competitors for nutrients, parasitism or inhibition of pathogens, antibiosis, and production of lytic enzymes [51,52]. In this study, we investigated T. harzianum strains CMML206 and CMML207 for dual culture antagonistic activity and observed that these two biocontrol agents could cut down the pathogenic fungal growth up to 85 . A equivalent antagonistic agent T. asperellum was isolated as a pathogen from the sweet potato storage roots, which inhibited the development of pathogens which include F. oxysporum, F. proliferatum, L. theobromae, and Rhizopus nigricans [12]. Hence, extra consideration must be offered to test option biocontrol systems to decrease ailments of sweet potato with Trichoderma spp. also as other biocontrol agents.Supplementary Components: The following are out there on line at https://www.mdpi.com/article/ ten.3390/jof7110927/s1, Table S1, List of fungal isolates from postharvest sweet potatoes in Korea and primers were applied for identification in the isolates in this study.
