Webinar: Tree Decay a few questions still worth asking with Dr David Lonsdale 

In 1982, David Lonsdale took on the job of leading a research project on decay in amenity trees. At the time, tree work practices were changing in response to research findings in the USA, where Alex Shigo and co-workers had developed the concept of “compartmentalisation of decay in trees” (CODIT). They had also demonstrated failures of wound paints to prevent decay.
The resulting changes in tree work practice are now long established but David believes that there are still questions worth asking, especially the following:
🌳 The CODIT model was developed to replace the allegedly flawed heart-rot concept, which dated back to the late 19th century. Was the heart-rot concept really flawed?
🌳 Are decay fungi ever parasitic or pathogenic?
🌳 The “D” in CODIT is now often taken to represent dysfunction, rather than decay. Why might this be appropriate?
🌳 Wound paints: are they really useless?
🌳 Biocontrol of decay in pruning wounds: could this be worthwhile?
