“…Aerated and non-aerated compost teas obtained from spent mushroom compost (SMC), grape marc compost (GMC), crop residues compost (CRC), and crop residues vermicompost (CRV) provided significant in vitro suppression of L. fungicola [53]. In further work, the authors reported that the microbial community of these compost teas is the main factor responsible for the antagonistic effect against mycoparasites [73], which is in accordance with the state-of-the-art [74]. The selective suppressive effect noted in teas from SMC towards the mycoparasites could be related to the selectivity of mushroom compost for the growth of A. bisporus, which means that the native microbiota inhabiting this environmental niche is innocuous for the host while exhibiting fungitoxicity against the mycoparasites.…”

Mycoparasites cause heavy losses in commercial mushroom farms worldwide. The negative impact of fungal diseases such as dry bubble (Lecanicillium fungicola), cobweb (Cladobotryum spp.), wet bubble (Mycogone perniciosa), and green mold (Trichoderma spp.) constrains yield and harvest quality while reducing the cropping surface or damaging basidiomes. Currently, in order to fight fungal diseases, preventive measurements consist of applying intensive cleaning during cropping and by the end of the crop cycle, together with the application of selective active substances with proved fungicidal action. Notwithstanding the foregoing, the redundant application of the same fungicides has been conducted to the occurrence of resistant strains, hence, reviewing reported evidence of resistance occurrence and introducing unconventional treatments is worthy to pave the way towards the design of integrated disease management (IDM) programs. This work reviews aspects concerning chemical control, reduced sensitivity to fungicides, and additional control methods, including genomic resources for data mining, to cope with mycoparasites in the mushroom industry.

“…Al-Mamari, Al-Sadi, Babu, Al-Mahmooli, Velazhahan palakrishnan, 2017). Riahi et al (2012) identified three bacterial species viz, Bacillus subtilis, B. licheniformis and B. amyloliquefaciens from the extract of leached spent mushroom compost that showed antagonistic effect towards Lecanicillium fungicola, the causal agent of dry bubble disease of button mushroom. In the present study, none of the bacterial isolates showed substantial level of suppression of growth of P. aphanidermatum and all the bacterial isolates recorded less than 5 mm inhibition zone.…”

“…The potential of SMS in large-scale enzymes production, plant diseases control, bioremediation, fertilizer, vermicomposting and for feeding animals has been documented (Inagaki and Yamaguchi, 2009;Ahlawat et al, 2011;Parada et al, 2011;Parada et al, 2012;Kwak et al, 2015;Roy et al, 2015). Several reports indicated the effectiveness of SMS in plant disease management (Yohalem et al, 1996;Uzun, 2004;Goonani et al, 2011;Riahi et al, 2012). Riahi et al (2012) demonstrated that the extract of SMS inhibited the growth of Lecanicillium fungicola, the causal fungus of dry bubble disease of A. bisporus.…”

The antagonistic microorganisms present in the SMS were attributed to the disease suppression (Riahi et al, 2012). The objectives of the present study were to isolate and characterize the bacterial species present in the spent mushroom substrate of A. bisporus in Oman and to study their in vitro antagonistic potential, plant growth-promoting trait and IAA producing ability.…”

Spent mushroom substrate (SMS) is widely used as fertilizer and to control plant diseases. The microorganisms surviving in SMS play a crucial role in plant growth promotion and biocontrol properties of SMS. In this study, an effort was made to isolate and characterize the bacterial species present in the SMS of Agaricus bisporus and to study their antagonistic potential, plant growth-promoting ability and indole-3-acetic acid (IAA) producing trait. Six different bacterial isolates exhibiting morphological variabilities were obtained from the SMS by serial dilution technique. On the basis of 16S rRNA gene sequences, these isolates were identified as Staphylococcus epidermidis (Sh1 and Sh3), S. aureus (Sh2), Bacillus albus (Sh4), Delftia lacustris (Sh6) and Comamonas aquatica (Sh7). These bacterial strains were assayed for their antagonism against Pythium aphanidermatum, a phytopathogenic oomycete. The results of in vitro dual culture assay revealed that all the 6 bacterial isolates showed low levels of suppression of P. aphanidermatum and recorded less than 5 mm inhibition zone. Among the bacterial isolates, S. epidermidis Sh3 recorded the maximum inhibition zone of 4.2 mm. Plant growth promotion test using roll paper towel method revealed that C. aquatica Sh7, B. albus Sh4, D. lacustris Sh6 and S. epidermidis Sh3 caused a significant increase in seedling vigour of cucumber compared to control. The seeds treated with the bacterial isolate C. aquatica Sh7 showed the maximum seedling vigor. Assessment of in vitro production of IAA by the bacterial isolates revealed that the bacterial isolates highly varied (ranging from 0.28 to 9.25 mg L-1) in their potential for production of IAA. The maximum amount of IAA was produced by C. aquatica Sh7 (9.25 mg L-1), while the minimum was produced by S. epidermidis Sh1 (0.28 mg L-1).
