Hl. Brown et A. Bruce, Assessment of the biocontrol potential of a Trichoderma viride isolate - Part I: Establishment of field and fungal cellar trials, INT BIO BIO, 44(4), 1999, pp. 219-223
A field trial has been set up to assess the biological control potential of
a Trichoderma viride isolate, T60. This isolate had been shown in previous
laboratory tests to be particularly effective against certain basidiomycet
e decay fungi. Wood was treated with T60 sports using vacuum pressure impre
gnation in a pilot presentation plant. Treated stakes were planted in the f
ield site along with CCA-treated and untreated control samples. Replicate s
amples were also set up in an accelerated decay facility employed to give a
comparison to the field trial results. This paper describes the setting up
and monitoring of the field and fungal cellar trials, and presents results
of moisture monitoring and sapstain assessment which indicate that Trichod
erma viride isolate T60 has a marked effect on the rate of sapstain develop
ment under certain conditions. The paper also discusses the efficacy of pre
ssure impregnation of spore suspensions for use as biological control agent
