Fig. 10.3 Biological control of gorse ( Ulex europaeus ) by using cut-stump treatment with
Chondrostereum purpureum in New Zealand. Top: Two adjacent gorse plants 12 months after treat-
ment. The plant on the left ( green marker) was only cut but not treated with the fungus (control
treatment) and the stump on the right ( yellow marker) was cut and immediately treated with
C. purpureum . The arrows point to gorse regrowing in the cut-only treatment ( left ) and dead stumps
with no sign of regrowth in the fungus treatment ( right ). Bottom : A closeup of one of the cut and
treated gorse plants 12 months after treatment showing the fruiting bodies of the basidiomycetous
C. purpureum (picture credit: Graeme Bourdôt, AgResearch Limited, Lincoln, New Zealand)
Following the confirmation of specificity of this pathogen to C. hirta , permission
was granted in 1986 by the Hawaii Board of Agriculture to use C. gloeosporioides
f. sp. clidemiae to control clidemia. Repeated field inoculations undertaken from
1986 until 1992 at Aiea State Park, Oahu resulted in significant control of the weed
