“…However, resistance to fungicides in current use by plant pathogens has stimulated a search for more effective disease control materials [3]. Basidiomycetes are known to produce a large number of biologically active compounds [4,5] with antibacterial, antifungal, antiviral, cytotoxic or hallucinogenic activity [6][7][8][9][10]. Several compounds isolated from wild macrofungi (mushrooms) also showed strong inhibition against the growth of a large spectrum of saprophytic and phytopathogenic fungi [4,11,12].…”

Culture filtrates of five strains of Clitocybe nuda displayed various degrees of antimicrobial activity against plant pathogenic fungi and/or bacteria tested. The culture filtrate of C. nuda strain LA82 was very effective in reducing the incidence of Phytophthora blight of pepper caused by Phytophthora capsici and the incidence of leaf spot on pepper caused by Xanthomonas axonopodis pv. vesicatoria. The inhibitory substance in the C. nuda strain LA82 culture filtrate was stable at low and high pH. It was also stable at high temperature. The inhibitory substance was dialyzable in the membrane tubing with molecular weight cut-off of 1000 but not 500 or 100. It was also exchangeable by anion but not cation exchange resins, indicating that the inhibitor has a molecular weight between 1000 and 500, and negative charge on its molecule. The inhibitor is a hydrophilic compound, but not a protein.

Secondary metabolites of Clitocybe nuda displayed antimicrobial activity against Phytophthora capsici. The culture filtrate of C. nuda was extracted with ethanol and chromatographically separated on a Sephadex LH-20 column and fractionated on a silica gel column to give eight fractions. These fractions were tested for the ability to inhibit zoospore germination of P. capsici . The most active fraction was further purified by silica gel column chromatography to yield three compounds: 2-methoxy-5-methyl-6-methoxymethyl-p-benzoquinone (1), 6-hydroxy-2H-pyran-3-carbaldehyde (2), and indole-3-carbaldehyde (3), all new to C. nuda. At a concentration of 500 mg/L, compound 3 showed complete inhibition of zoospore germination, while compounds 1 and 2 showed inhibition rates of 97 and 86%, respectively. To our knowledge, compound 1 is a newly discovered compound and, for the other two compounds, this is the first report in C. nuda. These compounds are potential candidates for new edible fungi-derived pesticides for the control of plant diseases.
