bleeding cankers

[arnoldbuchsassinger]

I spotted the bruise on tree, while working on another tree, and happened to investigate. I was also doing some research on cankers because i have worked on several genus with bleeding canker, in advanced stages mostly. I was looking at the possibility of using the tree as a guinea pig for the alicin research data. As a guinea pig is the important part.

Alicin take up can be checked by randomly selecting foliage, crushing the leaves should produce a powerful smell of garlic. This way you know that the Alicin has been taken up by the vascular system, I am under no illusion that the Alicin is going to make any difference, and the customer is the same.

I'm still advocating for the goat hoofed horned one.

 

My point is - no useful information can be produced by this experiment!

Lets look at the options;

 

a) Canker gets better

b) No change

c) Canker gets worse

 

In any of these cases, can we attribute the effect to the cause? No. In order to properly infer causation we need a strong data set, proven statistical correlation and a indication in the confidence of both.

 

One tree is not a trial. What's needed is a systematic, controlled and repeatable experiment that generates enough data to satisfy statistical analysis.

 

Now, don't get me wrong. I appreciate the proactive plant health care you are interested in, I'm just trying to give it all a rough ride. Good science can handle the hardest kickings.

Errr... has the casual agent causing the stem bleeding been identified....?

 

How can you diagnose the cure without knowing the cause...??

 

Such stem exudation can have many causes....

Indeed. Don't worry though - Allicin can cure everything so a detailed diagnosis is not necessary!

You might be right Tony!!!

 

We both know the smell of bullshite dude......
