Need Pro Advice concerning pseudomonas

That must be so hard, nice that you have a positive attitude about it. Did the larch bite it?

All of the Larch, Junipers, Tropicals, Yew, Boxwood, and 1 Crabapple were not hit. I am however going to treat the few things that are left starting tomorrow with Agri-Mycin as a precaution. It seems at this time Coniferous types have been resistant.

Really sorry to hear about this. I have to say, though, I admire your spirit and tenacity! If this happened to me, I'd probably throw in the towel on growing bonsai and stick with admiring the efforts of the many terrific artists in the Rochester area (as well as the National Exhibition every two years).

As it is, I'm questioning how I want to proceed. I have some plants that are really struggling, don't think it was the winter but could be a contributing factor. I'm also dealing with an attack of bark boring beetles in my grow bed, they are nasty and very efficient killers...capable of destroying years of work in a few weeks.

P. syringae is airborne, as well.

Zerotol may be effective - a homemade equivalent is 2 tbls hydrogen peroxide (3%) per quart of water and can be sprayed as well as used safely as a soil drench on live plants.
I haven't heard of this before. Have you used this with success?

Grimmy sorry to hear of the infestation. You're taking the right steps and have a great attitude!
 
Which species got hit Grim?

Had the time and back left to properly lawn bag 22 trees :(

13 were Lace leaf, Tridents, Fairy hair, and Amur Maples.
3 Elms .
3 Hornbeams.
2 Mulberry.
1 Crabapple.

And about 15 whips for grafting along with all of the substrate.

Five shrubs went as well -

1 Quince.
1 Cotoneaster and cuttings.
2 Crepe Myrtle.
4 Azalea whips, several young plants.
1 Compact Ilex

All are in sealed proper packaging and destined for landfill on Wednesday.

So far it seems none of the coniferous type plants were harmed( Larch, Junipers, Yew, Cedar, etc...) nor the 2 old Azalea. Also it appears no damage so far on any of the Tropicals.

Ugh....that sucks. I said it before but I am sad for you.

Id probably have to think hard about hanging up the branch cutters if I lost that many, particularly if they were trees Id invested alot of time/money and done alot of work on.
 
have to think hard about hanging up the branch cutters

The thought crossed my mind prior to cleanup. Late 2013 when we moved here I only moved what was either good or a favorite. I replanted close to 200 at the old place, donated many to NPO's to auction for benefit. Gave some away while keeping only what I considered a few at the time.
On a "bright" note I have reset the slope in this yard properly, disinfected and cleaned every related item and can Winter with confidence in years to come. Seems the corner I used coupled with a long damp dark Spring triggered it. By fixing the slope(providing drainage) and opening up space under the fence(better air circulation) we should not have any more problems. I suspect when I start buying again I will have better stock knowing what to look for. I certainly have enough pots and trainers:p

Well there are positives to everything I suppose.

Grow area improvement and lots of pots.
Not to mention the knowledge gained.

Would you still spray a preventative in the spring for a few years anyway?

Yes I will be using Agri-mycin 17 fungicide a few times during growing season as well. Probably for at least two seasons. It is bacterial so any single spore could cause a problem. Right now even the new soil placed on what I removed has been getting chlorine treatments. Liken it to cleaning up a Hospital with staff infection:eek:

I haven't heard of this before. Have you used this with success?
I have had some troubles that Gary Wood advised me might be bacterial and suggested ZeroTol. I am not at all certain that p.s. has infected any of my trees nor am I certain of any beneficial effects, as yet. Nevertheless, I am adding 2 tbls 3% peroxide per quart when fungicide is warranted. IIRC, Wood uses a zerotol root dip during transplanting. Mach5, for example, believes Zerotol is effective. Michael Hagedorn also recommends ZeroTol.
will copper work?
Hagedorn also recommends copper sulfate and Phyton 35 systemic.

Now you have 'heard' it.
 
Try to find some Zerotol, and you will see that it's been discontinued.

Says who? Quick web search revealed numerous places to purchase, such as:

http://growerssolution.com/PROD/zer...otol-27-percent-by-biosafe-2-5-gallon/71-3550

http://www.domyownpestcontrol.com/zerotol-20-p-10268.html?gclid=CK_54O2Qz8UCFQQRHwod6ZEAwg

http://www.forestrydistributing.com...gaecide-bactericide-fungicide-biosafe-systems

Looks like you can only get it in larger sizes but it doesn't appear to be discontinued.
 
Does this have a common name? The information I've found is pretty general and not very descriptive. Maybe because there are so many flavors. Where does it come from? How is it spread? What is the treatment other than "slash and burn"?


It is called pseudomonas syringae and one of the better articles is at this link:

http://pnwhandbooks.org/plantdiseas...-and-other-prokaryotes/diseases-caused-pseudo

Offline the Local Cooperative Extension is a great source and was most helpful to me as well as a grower I know.

If you catch it quickly before it spreads to much the portions of the plant that show any signs listed can be removed, cuts sealed, and both plant and substrate treated. My plants went from what appeared to be "buds suspended in time" for a couple of weeks. After that in a 48 hour period it ran through most all trunks and branches and only then was it visible.

It is like when Miracle Grow pulled 20-20-20 and you could still find it for at least a year later until all stock was depleted.

I am using Agri-mycin 17 fungicide anyways as it is also an effective treatment. My use will be different though as the plants and substrate are on their way to the landfill today. I will be treating the surfaces and general area for two seasons as a preventative.

I ordered some from Amazon when I had my leaf issue with my Hawthorn, and it got lost in transit. When I went back to try to find it again, all the places I looked said it was discontinued by the manufacturer. I looked around, and at that time couldn't find any. So I don't know what is up. Luckily the one that got lost in transit actually finally showed up.
 
At least you finally got it! Apparently they made a slight change to the ingredients and renamed it "zerotol 2.0", perhaps you were trying to find it during that period.
