kretzschmaria???

[Tim Ashburner]

Is this early kretzschmaria on lime (dark staining at about 2m a.g.l.)?

 Not neseccarily kretzschmaria.

 

In my experience the stem bleeds are usually associated with late stage decay of Kretz where there would usually be anamorphic or teleomorphic stages of fruit bodies present.

 

Your example could well be a bleeding canker infection like Phytophthora cactorum/citricola.

You're welcome Tim.

 

Confirmation of what it is or what it is not is the foundation of sound prognosis/prescription. 

 

Any root damage or evidence of lightning strike?

 

Have you sounded the stem around the infected area, any decay or change in resonance evident?

 

Consider sending of a bark sample for lab analysis.

 

Consider chasing out the infected bark tissue and sterilising the infection with heat.

 

But first try and attain confirmation of what it is.

I have seen it a few times locally, watched one lime slowly decline over 6 or 7 years as more lesions appeared.
