“…The use of biocontrol agents in managing soil-borne diseases is common in several areas of the world, especially under organic agriculture. Several biocontrol agents have been tested and used against Pythium, Rhizoctonia , and Fusarium species, including Trichoderma harzianum and Pseudomonas aeruginosa (Al-Hinai et al, 2010; Blaya et al, 2013; Halo, Al-Yahyai & Al-Sadi, 2018; Kazerooni, Rethinasamy & Al-Sadi, 2018). The biocontrol agents interfere with plant pathogens through the production of toxic metabolites and enzymes (e.g., cellulase), competition for food or space and/or direct parasitism (Bibi et al, 2017; Sharma, Salwan & Sharma, 2017; Vinale et al, 2017; Halo, Al-Yahyai & Al-Sadi, 2018; Zhang et al, 2018).…”

A study was conducted to investigate the potential of Aspergillus terreus obtained from Avicennia marina mangrove roots in inhibiting Pythium aphanidermatum and damping-off disease of cucumber. Aspergillus terreus exhibited in vitro inhibition of Pythium aphanidermatum growth. Electron microscope examination revealed that the antagonistic fungal isolate resulted in shrinking and groves in Pythium hypha. When Aspergillus terreus culture filtrate was added to Pythium aphanidermatum, it resulted in a significant increase (by 73%) in electrolyte leakage from Pythium hypha compared to the control, as well as significant reduction (by 71%) in oospore production. The Aspergillus terreus culture was also found to produce a cellulase enzyme, which is suggested to be involved in the antagonism against Pythium aphanidermatum. Adding Aspergillus terreus to soil infested with Pythium aphanidermatum significantly reduced percent mortality in cucumber seedlings by 70%. Aspergillus terreus, when applied alone on cucumber seedlings, did not show any suppressive effects on cucumber growth (length and fresh and dry weight). This appears to be the first report of isolation from mangrove of Aspergillus terreus with antagonistic activity against Pythium aphanidermatum-induced damping-off of cucumber. The study indicates that fungal isolates obtained from marine environments may serve as potential biocontrol agents against some plant pathogens.

“…nov. MycoBank) has been demonstrated as a mycoparasitic fungus against Botrytis cinerea causing onion scalp and umbel blights (Samson et al, 2011;Abdel-Rahim and Abo-Elyousr, 2018). Penicillium pinophilum was also reported to reduce soil-borne pathogens Pythium and Rhizoctonia-induced damping-off in cucumber in Oman (Kazerooni et al, 2019). We found sugar beet roots from a commercial field in Minnesota, USA with P. pinophilum.…”

Rhizoctonia solani is an economically important pathogen of sugar beet (Beta vulgaris L.) causing seedling damping-off, and root and crown rot. Cultural practices, partially resistant cultivars, and fungicides are among the methods most used to manage R. solani. Penicillium pinophilum, a potential bio-control agent for Rhizoctonia damping-off, was isolated from sugar beet. Our objective was to evaluate the bio-control potential of Penicillium pinophilum against R. solani AG 2-2 under laboratory and greenhouse conditions. In vitro co-culture of both fungi showed that R. solani growth was inhibited by P. pinophilum. A greenhouse inoculation study was done using sclerotia of R. solani and a conidia suspension of P. pinophilum to evaluate the response of a Rhizoctonia susceptible cultivar. Treatments included R. solani sclerotia, P. pinophilum conidia suspension, a combination of R. solani sclerotia with P. pinophilum conidia suspension, and a mock inoculation with water (control). One 2-cm deep furrow was made in the middle of peat filled trays into which 10 seeds were planted. Each treatment was applied adjacent to each seed and covered with peat. There were four replicates per treatment arranged in a completely randomized design. The sole sclerotia treatment caused 75% damping-off and severe root rot on surviving plants whereas the combination of sclerotia with P. pinophilum conidia suspension reduced damping-off by 755350%. No damping-off incidences were observed with the P. pinophilum conidia suspension or the mock-inoculated control. It was concluded that P. pinophilum has the potential to reduce damping-off caused by R. solani but use of the most appropriate P. pinophilum concentration and its mitigation mechanisms need further studies.

“…Current evidence concerning the capacity of Talaromyces, another Ascomycetes genus including several species reported as antagonists of plant pathogens [7][8][9], to directly interact with insects is examined in this paper in view of a more comprehensive consideration of their role in crop protection and possible applications in the biocontrol of these key pests.…”

Facing the urgent need to reduce the input of agrochemicals, in recent years, the ecological relationships between plants and their associated microorganisms have been increasingly considered as an essential tool for improving crop production. New findings and data have been accumulated showing that the application of fungi can go beyond the specific role that has been traditionally assigned to the species, employed in integrated pest management as entomopathogens or mycoparasites, and that strains combining both aptitudes can be identified and possibly used as multipurpose biocontrol agents. Mainly considered for their antagonistic relationships with plant pathogenic fungi, species in the genus Talaromyces have been more and more widely reported as insect associates in investigations carried out in various agricultural and non-agricultural contexts. Out of a total of over 170 species currently accepted in this genus, so far, 27 have been found to have an association with insects from 9 orders, with an evident increasing trend. The nature of their mutualistic and antagonistic relationships with insects, and their ability to synthesize bioactive compounds possibly involved in the expression of the latter kind of interactions, are analyzed in this paper with reference to the ecological impact and applicative perspectives in crop protection.
