“…An effective control of R. solani can be expected if the population of G. roseum can start at a higher density early in the growing season under suitable conditions for growth and spreading over the surface of stolons, stems and young tubers. Moody and Gindrat (1977) and Gindrat et al (1977) reported a moderate control of Phornopsis sclerotioides, causing cucumber black rot by G. roseum inoculated in greenhouse soils.…”

Gliocladium roseum was found to be the most common and probably the most effective mycoparasite in potato fields in the northern parts of the Netherlands. It is able to parasitize and kill living hyphae at temperatures of 12~ and higher. Sclerotia of R. solani are often infected and killed by this fungus under suitable conditions, i.e. at temperatures of 16 ~ and more. Killing of sclerotia by other antagonistic organisms was also observed. It is also shown by not parasitic fungi and is caused by toxins produced by the antagonist.The development of the G. roseum population was studied during the growth of a potato crop in two soils. In both soils its initial level was very low. In both a slightly acid sandy soil and a neutral sandy loam, suppression of R. solani can occur; G. roseum accumulated in the former mainly under continuous potato crops, Colletotrichum coccodes was the main antagonist in the latter.

“…have decreased the incidence of disease caused by R. solani and P. sclerotioides, Coniothyrium minitans Campbell has partly controlled Sclerotinia sclerotiorum (Lib.) de Bary, and Pythium oligandrum Dreschler has decreased damping-off caused by Pythium ultimum Trow (Gindrat, van der Hoeven & Moody, 1977;Sundheim, 1977;Chet & Baker, 1980;Elad, Chet & Katan, 1980;Trutmann, Keane & Merriman, 1980;Howell, 1982;Lutchmeah & Cooke, 1985;Marois & Locke, 1985;Lynch & Ebben, 1986;Sivan & Chet, 1986). The control obtained in the field or glasshouse has often been inconsistent and not reflected results obtained in preliminary in vitro screening tests.…”

SUMMARYThe growth of and interactions between the glasshouse pathogens, Rhizoctonia solani Kiihn, Fusarium oxysporum Schlect., Pyrenochaeta lycopersici Schneider & Gerlach, Phomopsis sclerotioides van Kesteren, Sclerotinia sclerotiorum (Lib.) de Bary and Botrytis cinerea Pers. and the antagonistic fungi, Trichoderma harzianum Rifai, Trichoderma viride Pers., Coniothyrium minitans Campbell, Gliocladium roseum (Link.) Bain and Pythium oligandrum Dreschlgr were examined on tap water agar, soil extract agar and potato dextrose agar. The medium had a significant effect on the growth rates of the fungi as well as the production of, and response to, volatile and non-volatile antibiotic compounds and hyphal interactions. Responses to the media appeared to be related both to inherent properties of the fungi and to their natural ecological behaviour. The significance of in vitro assays in screening systems for biological control agents of soil-borne plant pathogens is discussed.

“…As a potential biological control fungus, G. roseum has been successfully tested on different hosts against a range of microorganisms (Gindrat et al 1977;Zhang et al 1994). The mechanism of this antagonist against other microorganisms is recognized as its competitive and antibiotic activities (Seifert et al 1988).…”

Biological protection of hardwood logs destined for panel manufacturing using Gliocladium roseum against biodegradation

The objective of the present study was to develop a biological technology that would protect logs destined for oriented strand board (OSB) manufacturing from biodegradation. Aspen, red maple, and yellow birch trees were felled in one summer and the logs either debarked or not debarked, and either treated or not treated with a biological product of Gliocladium roseum. The logs were piled in different treatment groups and stored in a yard for 5 months and 1 year before evaluation. The results showed that all untreated logs, with or without bark, were seriously degraded by moulds, stain and decay fungi after a summer storage period of 5 months. The logs with bark were more degraded than the debarked logs, and the log ends were more degraded than the middle sections. After 5 months, 55-83% of the surface area of the wood discs was degraded in untreated logs. The biological treatment was effective, and only 4-16% of the surface area of the wood discs in treated logs was infected by various fungi. Strands cut from untreated logs consisted of 50-75% grey-or blue-stained strands, whereas those cut from biologically treated logs consisted of 10-25% such strands. Panels made using biologically treated logs had a lower thickness swelling and water absorption values compared to panels made using freshly cut logs and untreated stored logs. The other physical and mechanical properties of the various panels made in this test were comparable. In terms of mould resistance, all panels made from fungal-treated logs had a better mould resistance than those made from freshly cut and untreated logs.
