An Icky Alnus...Phytophthora or Drought?

[Nellybelly]

This sounds really bad, have you notified the FC?

 

I have but got got no joy:thumbdown:

 

There a black country noddy club and the sight of anything green is lost on most of them, if they had there way every bit of the river bank would be concreted like a canal tow path.

 

i'm going to get in touch with land owner instead as they tend to listen to the local lads, it's not much fun fishing there any more with tones of dead wood swinging in the wind above your head and the club have pretty much abandoned this stretch

Having read all the info on Phytopthora Alni on Forestry Comm site I'm inclined to agree with RobArb. All the symptoms point in that direction.

I never realised however how much of a problem it actually was in this country. A very informative pdf attached.

 

If i wanted 100% confirmation where would i send a sample to? Alice Holt?

 

Thanks for all input.

You can get a Phytopthora field testing kit.

 

I'll have a look and see if I can find a link.

Hi Sean,

 

There are hundreds of different Phytophthora’s and there is no way of telling the different between two types with out looking at samples in a laboratory.

 

On Alder you will have a very high chance that it is Phytophthora alni or it could be a type of Pseudomonas.

 

There are testing kits available to work out if ifs either Phytophthora or Pseudomas but not what type it is.

 

It doesn’t make that much of a different as the treatment is the same for both.

 

You will have to apply a Potassium Phosphite as a soil drench / soil injection at a dilution rate of 1:100 and at a rate of roughly 2 litres per square metre out to the drip line. Also paint the solution on to the stem where the points of bleeding are.

 

It may be to far gone, but it is worth a try.

 

Hope this helps,

 

Ian
