Bretts,

The only sure way of knowing what the correct treatment for your disease is, is through proper identification. Send a sample off to DPI if you REALLY want to know what the pathogen is that is infecting your trees.

Sure there is a range of pathogenicity in diseases that attack plants. There are also some that are difficult to get rid of once they've arrived. However, I don't think there is a killer fungus out there ready to consume my tridents, you want to disagree, fine. Personally, I'd be sending samples off for analysis rather than looking for answers on internet forums.

Yes I would love to put a name to this Fungus. I did look into getting the issue looked at in a lab and even talked to the head scientist (can't remember the place but he was a scientist who's major was root rot disease)who scared me by stating he feared it was a virus because it got worse after cutting back. I am sure I will cop it here but from my observations I think he was off the mark. :shock: What Brett you are disagreeing with a scientists advice :roll: It was only an over the phone diagnosis.


The issue there of course is cost. From memory I would not have walked away with change from $300 and that was if they found it first go with a foliar test. Add that again for a soil test and then a per hour the cost could go anywhere and no matter the cost there is no garantee they will find what it is.
Might be financially sound for a farming operation but I think my stock would be lucky to be worth that much.
Luckily enough Mela was able to get a test done and although we missed giving it a name it was good to have a treatment advised that is working.

I have learnt that being hard to get rid of is the norm for this type of fungus. Winter precautions are the best attack. That is why I have been impressed with the results from Bravo which can not kill the fungus but workes as a protect ant.
I have stopped taking this fungus personal as I have seen that many are going through the same and I have fared better than others (but not all) in a year that I probably had too many trees to care for in the best of circumstances. Yet I have privet that are absolutely going stupid (weird) that accomplished practitioners shake their head at wondering what is going on.

If I thought this was the case I would just throw them all out and move to a species that does not have the issue. I am hoping that once I/we get through this season with treatment and precautions over the winter months we will have it under control next spring.
But there is a possibility that this will have a dramatic impact on what I am able to grow here. I know Don has given up on growing Juniper just for something that is as simple as spider mite. They desiccate his juniper where he is and found it was not worth the trouble. Would you insinuate that that pest is being opportunistic because of his care of Juniper.
Talking on the Internet is only one of my avenues of searching for a solution. But without it I would not have been advised of the Bravo treatment which has been very beneficial.

It's too bad your in such a hurry cause the stories I could tell you, Bushels and baskets of stories, hole crates full of stories. But if you can spare a moment I will tell you one story.

I have sprayed and defoliated from advice in experimental conditions I have done nothing on a whim but only followed advice I was given. This advice has been from some of the best in our country and abroad. Why should I be concerned about your weird rant.
Your suggestion of Peach Leaf Curl is about as far from the mark as we have been so I would say it is you that needs to look at the advice given.

A wierd rant? What utter tripe, Brett! :roll: :roll: :roll: :roll: :roll: :roll:

You have a PM.

What would you call it when a suggestion is given of a disease that looks like nothing we are experiencing and then you get upset when I don't treat our trees for it :roll:
Since you have not experienced this fungus maybe you should listen to the experience of people that have as one day it might knock on your door.
Like I said I have talked to a number of very experienced practitioners about this and I am confident in my appraisal of said advice.
