Treating stumps

[skyhuck]

Chipping infected material can create aerosol spores that can travel for many miles (from any diseased wood). Once in the air they can travel onto other sites, with no regard to site boundaries and ownership. Regardless of however many trees may be infected on a particular site, a neighbouring site may not be. Avoiding chipping infected wood is a good practice.

 

Is it not the case that most pathogens are present in the environment all the time, its opportunity (weakened tree, root damage, etc) that causes infection.

Which pathogens?

 

Some are present - even in the most sterile environment. Some are invaders, such as HCBC which has not been in this country as long at the hc tree (c1600 v c2000) and are spread either naturally or by us. If by us then we should do what we can to limit our actions that may spread it.
