Not enough information to be making pesticide recommendations. They were assuming this material would probably take care of it. That's fine if that's true, as far as you are concerned. If not, then you will have wasted your time and money.

What information is needed to make recommendatons? Is phyton a pesticide or a fungicide?

Your brief description does not make reliable identification of the problem possible. Some plant disease conditions even have to be tested for to be nailed with certainty, same as a medical condition. The answer you got was based on an assumption, not a diagnosis.

Phyton 27 is a water soluable copper fungicide and bacteriacide.

I agree that the symptoms you describle are inconclusive as to the cause and to recommend Phyton is not a great solution. By the way, Phyon is very expensive, as all commercial grade plant chemicals are and I would not jump to using it without a more solid reason.

Paul3636,

I did some research over the internet over the last couple of weeks regarding phyton 27. From what I found (and what they claim) from the different forums etc, phyton 27 seems to do a good job of preventing and curing verticillium in the early stages and a couple of other fungus infections.
Their website has some articles on this. Like MJH mentioned the product is expensive $17 for 2oz bottle.
So unless the problem is verticillium or one of the other 2 or 3 fungus infections, phyton 27 may not be helpful.

Is there an organic method of preventing fungus, if it is a fungus. I have other maples around the red pygmy and none of them have drying leaves, in fact they are all healthy.

It is difficult to protect J. maples against possible fungal wilt/rot problems as the pathogens tend to be soil borne and in many cases, omnipresent. Perhaps the best way to protect them is to keep them as stress-free as possible - a stressed tree tends to be more susceptible to these problems while well grown/sited, healthy trees are most resistant to these pretty common soil pathogens.

My experience with phyton-27 is that it is most effective if used early in the treatment - well advanced wilt problems will not respond. Without seeing your tree and accurately diagnosing the problem, it is difficult to know if this product would be of benefit, but based on your description, I doubt it.

btw, "pesticide" is an umbrella term for various 'cides - fungicides, herbicides, insecticides, miticides, etc. are ALL considered pesticides.
