“…However, investigations from Finland, Canada and New Zealand showed that C . purpureum strains are genetically diverse, and are not associated with a specific host species or ecological region [ 11 , 17 , 18 ]. Thus, it is possible that the most efficient strain, R5 3 , is efficient also against the sprouting of other tree species and in other geographical areas.…”

“…purpureum is a basidiomycete commonly found on wounded broad-leaved wood in boreal and temperate vegetation zones in Europe [ 15 , 16 , 17 ]. The fungus is widespread in nature due to its efficient basidiospore production resulting in frequent new infections [ 15 , 18 ]. In nature, monokaryotic spores landing on wood first germinate, after which the hyphae from different spores hybridize and form dikaryotic mycelia which then colonize the host [ 18 ].…”

We tested whether the pairing of selected isolates could be used to increase the efficiency of a decay fungus Chondrostereum purpureum (Pers. Ex Fr.) Pouzar to control hardwood sprouting in Finland. We paired C. purpureum strains efficient in sprout control or highly active in laccase production, and tested the efficacy of their progeny in spout control experiments. This procedure resulted in a strain with an efficacy superior to that of the parental strains. The mortality of birch (Betula pendula Roth. and B. pubescens Ehrh.) 1 cm in stump diameter was 78%, 56% and 9% for the best progeny, the best parental strain and the control, respectively. Mortality was only slightly higher for B. pendula than for B. pubescens but no significant differences were found between the number or maximum height of stump sprouts. Our results showed that cross breeding of this decay fungus is a good alternative in attempts to produce efficient biocontrol agents against hardwood sprouting.

“…This contrasts with 2Á/4 years before the effects of applied C. purpureum have been evident in other species (Wall 1990(Wall , 1994Dumas et al 1997;Jobidon 1998;Shamoun & Hintz 1998;Becker et al 1999;Harper et al 1999;Pitt et al 1999;Conlin et al 2000). Large differences between hosts in the rate of xylem tissue invasion by C. purpureum have been described (Spiers et al 2000), suggesting that a high invasion rate of the xylem tissues in gorse may explain the rapid disease development.…”

“…In Canada, molecular studies showed that genetic exchange occurs freely across Canada and that there is little risk that a mycoherbicide isolate would introduce rare alleles to a local population of C. purpureum (Ramsfield et al 1996). Similarly in New Zealand, C. purpureum is genetically highly diverse with no host species or locality specialisation (Spiers et al 2000), indicating that a single isolate could also be used throughout New Zealand.…”

An experiment was conducted in two gorse populations (Ulex europaeus ) in which Chondrostereum purpureum was applied each month as mycelial-agar cultures to the wounds of decapitated stems of previously untreated gorse plants to determine its potential as a mycoherbicide. Summer Á/autumn (Feb Á/May) or late winter Á/early spring (Aug Á/Sept) applications were effective in both populations, halving stem stump survival (from an average of 56 to 29%). Another experiment in the same gorse populations evaluated the combined effects of C. purpureum applied in May to decapitated stems, and Fusarium tumidum applied as spores in an invert emulsion to regenerative shoots 5 Á/6 months later. There was no evidence of synergism between the two fungi; each pathogen independently reduced the density of regenerative shoots on the decapitated stems by 39 Á/63% averaged over the 12 months following their respective applications. It is concluded that both pathogens have potential as mycoherbicides for gorse regenerating after stem decapitation.

A decay fungus, Chondrostereum purpureum (Pers. Ex Fr.) Pouzar, has been investigated in Europe, Northern America and New Zealand for its ability to decay hardwood stumps and thus prevent sprouting. The aim of these investigations has been to find an alternative to mechanical (cutting only) and chemical sprout control (cutting and applying chemicals to stumps in order to prevent sprouting). Mechanical sprout control is not an efficient option due to hardwood tree species’ ability to re-sprout efficiently after cutting, and therefore management costs are high. Chemicals would be efficient but due to their harmful effects on the environment, alternatives are needed. The fungal treatment, i.e., cutting accompanied with C. purpureum inoculum is an environmentally friendly and efficient option for sprout control. This mini-review comprises the role and function of C. purpureum in biocontrol of trees: the ecology of C. purpureum, its sprout control efficacy, factors affecting sprout control efficacy, devices in biological sprout control, potential risks, and the future perspectives of biological sprout control. Key points • A fungus Chondrostereum purpureum is efficient in preventing sprouting of hardwoods • C. purpureum is not sensitive to environmental conditions • Devices should be developed for cost-efficient biological sprout control
