“…This result suggested that substances produced by C. nuda had the ability to suppress Pythium damping-off. The inhibitory effects of culture filtrates of C. nuda on the growth of plant fungal and bacterial pathogens have been demonstrated in previous studies (Chen & Huang 2009). The antimicrobial compounds of C. nuda against Phytophthora capsici have been identified as 2methoxy-5-methyl-6-methoxymethyl-p-benzoquinone, indole-3-carbaldehyde and 6-Hydroxy-2Hpyran-3-carbaldehyde (Chen et al 2012).…”

SUMMARYPythium damping-off caused by Pythium aphanidermatum usually occurs in commercial nurseries of cucumber seedlings. The purpose of the present study was to develop a container medium for effectively suppressing Pythium damping-off of cucumber seedlings. Seven agricultural materials were tested for their suitability as substrates for the growth of cucumber seedlings. Bas Van Burren No. 4 peat moss (BVB) was able to promote the growth of cucumber seedlings, but it was ineffective against Pythium damping-off. Spent blewit mushroom compost (SBMC) was an available substrate that could inhibit P. aphanidermatum, but it also inhibited the growth of cucumber seedlings slightly. A cultural medium, spent blewit peat compost (SBPC), containing 50% (v/v) SBMC, 50% (v/v) BVB and 0·3% (w/v) lime was consequently formulated. The SBPC was able to promote the growth of cucumber seedlings and reduce the incidence of Pythium damping-off. A total of 20 micro-organisms were isolated from SBMC compost and screened in steamed SBPC medium for their ability to inhibit the growth of P. aphanidermatum. Among these, Bacillus aryabhattai isolate number CB13 was able to suppress P. aphanidermatum significantly in the steamed SBPC medium. Thus, bio-formulation of SBPC medium with the beneficial microbe B. aryabhattai CB13 was carried out. The incidence of Pythium damping-off was reduced from 58% in steamed SBPC medium to 4% in the bio-formulated container medium. The novel bio-formulation has high potential for controlling Pythium damping-off in commercial nurseries.

“…To estimate the molecular weight of the inhibitory substance, 5 ml of the extract was placed in a molecular porous membrane tubing with molecular weight cut-off of 100, 500, 1000 or 10,000 (Spectrum Medical Industries Inc., Los Angeles, CA), dialyzed at 24 8C against 1000 ml distilled water changed three times over a 24-h period, and used for germination tests [20].…”

“…Also, culture filtrate of Clitocybe nuda (an edible mushroom) was very effective in reducing the incidence of Phytophthora blight and leaf spot on pepper caused by Phytophthora capsici and Xanthomonas axonopodis pv. vesicatoria, respectively (Chen and Huang 2009). The culture filtrate of Trichothecium roseum MML003 strongly inhibited the mycelial growth and sclerotial formation of the rice sheath blight pathogen, Rhizoctonia solani (Jayaprakashvel et al 2010).…”

The inhibitory effects of secondary metabolites of Sclerotium cepivorum against itself were studied both in vitro and in vivo. The highest inhibition of fungal growth and a 98.6 % reduction in the number of sclerotia was obtained with 50 % culture filtrate. No sclerotial germination was observed on media amended with culture filtrates at 10, 25 and 50 %. Methanol extract of mycelia and sclerotia, and ethyl acetate extract of culture filtrate both exhibited over 90 % inhibition of S. cepivorum growth at 1200 ppm. A chloroform extract of culture filtrate resulted in 71.1 % inhibition at 1200 ppm. All extracts completely suppressed the formation and germination of sclerotia at 400, 800 and 1200 ppm. In greenhouse experiments, no disease was observed with the ethyl acetate extract when onion seedlings were dipped in the extract for 4 or 8 h. The GC-MS analysis revealed 28 compounds in the methanol extract. The methanol extract contained mainly hexadecanoic acid methyl ester (31.16 %), whereas 5-hydroxymethylfurfural, HMF, (36.40 %) was the main constituent of the ethyl acetate extract. These results suggest that the secondary metabolites of S. cepivorum are potential and promising antifungal agents for the control of onion white rot. These results can be also applied to reduce the incidence and severity of other diseases in different crops.
