Biological treatments for the control of decay in tree wounds.: Laboratory tests

Non-decay fungi and bacteria which had been isolated from pruning wounds of beech (Fagus sylvatica) were examined for their ability to check the growth of decay fungi in a number of laboratory tests. Several fungi and bacteria inhibited growth although the degree of inhibition varied to some extent with the test. The most consistently antagonistic fungi were Trichoderma spp., especially an isolate of T. viride. The most antagonistic bacteria were Bacillus spp.
