A pine tree with pine wilt. Wilt diseases in woody plants tend to fall into two major categories, those that start with the branches and those that start with the roots. Those that start with the branches most often start with pathogens that feed on the leaves or bark, those that start with the roots start with wounding or direct entry by the ...
The trees die from failure to take up water and nutrients because the main roots are decayed. The death is also accelerated by wind that throws the trees down. It is estimated that Laminated root rot reduces timber production by about 4.4 million cubic meters annually. [4] Wood losses in British Columbia are estimated to be 1.4 million cubic ...
