I came back to rewatch this one. I have what I think is fireblight in almost every one of my 40 year old apple trees. The branches are fine but the trunks have black on them below the first branches and are oozing amber sap. The rest of the tree seems okay and new shoots are happy too. Trying to plant zone 3 hardy resistant or immune varieties is more difficult than it looks. I appreciate your take as we don't have any orchards for 50 miles or more and plan to hopefully eat the fruit for a few years while the new trees grow.

[@StefanSobkowiak]

Sounds like you have a problem with borers, an insect that bores into the trunk.

[@miketaylor3408]

According to my local extension office: Fire blight doesn’t spread tree to tree through the air. It’s a naturally occurring bacteria in the air. But it can spread on contact. You need to disinfect your clippers between cuts. It’s also okay to replant in the same spot. It can only infect trees through the air when they are flowering.

[@lesliejacobs3002]

I never know about the extension agents… ( I have visited them In many states).they are the same ones that gave out Russian olive trees in Wyoming to anyone with a pulse.. now they want you..at your cost to cut them out.

Bees spread it.

[@Skashoon]

What you said is a lesson to learn for all of us. Paraphrasing: Should we fight disease? It’s natures way of removing those cultivars that are susceptible and unsuitable for the conditions at your location. I wholeheartedly agree. I hadn’t considered it but, you’re absolutely correct. I appreciate the references to the mycelium and those who have found the connections to immunity as a result. There must exist a database with this information. Now if we can inoculate with the correct mycelium when planted, we might just make headway.

Hey Matt Cappel: Never go nuclear with chemicals, as you probably already know you'll be resetting your soil and putting a Band-Aid on the problem my suggestion would be fungal dominated compost teas apply as root drench and a foliar application twice a week right before and during bloom,the biofilm will form a protective layer from disease.

When you prune the fire blight limbs out, do you dip your pruners into a disinfectant of some kind so it doesn't infect the healthy section at the site of the next cut?

Should always use H2O2 hydrogen peroxide (which is a water molecule with an added oxygen atom) which kills all bacteria, fungus, mold, viruses and the rest, especially if you want to stay organic. Chemicals are really bad and chlorine used in pools have been linked to cancer and other ailments. In fact chlorine and fluoride displace iodine from the body which is needed for a healthy active thyroid, and pretty much everyone is iodine deficient. You can even water trees and plants with added H2O2 to add oxygen to the soil, helps with root rot. You can buy 3% everywhere (people used to use it as a mouth wash or for cuts decades a go) or large container of 50% (which will burn you) and dilute 1 part to 12 or 13 to make 3%. 3% may be diluted 1 to 9 to get it to 0.3%, it's trial and error.

"There must be a bug in there that the bird wants," was my conclusion. It has had some very tough, lean Summers with either extreme heat and strong winds tagged along with a poorly done hard pruning a number of years ago. I want to try and rejuvenate it because it had some wonderful fruit at one time. My parents planted it over 30 years ago when they moved into the house.

That big pear tree is a born warrior. While watching it I said to myself, if nature wants it to be gone then why would it let the tree bear fruits, then I realized that it must have been fighting the Fireblight from the beginning as a plant, it succeeded in suppressing it before bearing little fruits and when it started producing lot of fruits it must have gotten little weaker, just like a mother would get weaker when bearing a baby. I'm really hoping it would win this long lasting war and stand there like a proud warrior, if so you can use the seeds to plant new ones and this time they r born immune to Fireblight that would be awesome to watch. So till now it is fighting on it's own but now it has the help of human to fight it (cutting those infected one's)....does it mean it has more chance to win the war?

Has fire blight affected your non grafted pear trees, you may want to experiment. “The microbe is nothing. The terrain is everything.” Louis Pasteur (1822-1895) is purported to have made this statement on his deathbed. The origin of the quote is attributed to Claude Bernard (1813-1878), a physiologist and contemporary of Pasteur. By quoting Bernard, Pasteur was recanting his germ theory, a theory that assigned the cause of disease to microbes invading and reeking havoc on the body, with specific germs causing specific diseases. In contrast to Pasteur, Claude Bernard and Antoine Bechamp (1816-1908), another contemporary of Pasteur, believed disease was a condition of imbalance in the internal terrain of body. Bernard and Bechamp emphasized the context or environment in which germs lived and not the germs. On the one hand, if the terrain was balanced (homeostatic), then germs could not flourish. On the other hand, if the terrain were out of balance, then germs would thrive. In short, germs do not cause disease. Instead, they are a sign of the diseased conditions of the terrain and not the cause of those conditions (see Stockton, 2000).

[@georgekallis3337]

Claude Bernard@Klaa2 That's what I said. Pasteur acknowledges that he was wrong and his opposition Claude Bernard was right all along.

[@StefanSobkowiak]

Your video would have made diagnosis a lot faster! But now it’s here to help save other trees.

[@voxintenebris6367]

I currently have fireblight damage on my two Conference pear trees, I have pruned it out (or so I thought) over the past two years, but I still have to deal with it. My trees were so healthy, they were admired by the neighbours and visitors, then a new family arrived with a cat. The cat decided that the trees were the perfect scratching posts and within one season, the gouges in the bark deepened. The cat then climbed the tree and broke a main branch. Added to this, a neighbour neglects her trees which show signs of fireblight. My trees succumbed. In the UK, fireblight was a notifiable disease, but is no longer. I have read that other plants pose a risk as they act as a host - these are blackthorn, hawthorn, photinia. From what I have read, the disease is transferred, as you say by either insects or birds; it is not carried on the wind as far as I am aware. I have also read that if the soil contains too much nitrate that that does not help, the excessive leaf growth weakens the structure and resilience of the tree. I think I am guilty here, as I have not only emptied old growbags on the site but in addition, I have dug in pea roots. The tree has an abundance of long shoots (now cut back) so that may indicate excess nitrate. From a distance, my tree -with its glorious leaves - looks healthy, it even bears fruit, but it still has the problem. More pruning ahead for me. I won't give up on the trees until the balance goes in favour of cutting them down. I took the pruning opportunity to reshape them into more of an open espalier type framework, the tree seems to respond to this, so fingers crossed. Great video, I can empathise!

[@StefanSobkowiak]

You nailed it, excess nitrogen gives excess growth which favours fireblight. Try training branches to level angle instead of pruning as extra pruning will just encourage more vigour. Good luck.

[@voxintenebris6367]

@@@StefanSobkowiak Thanks for the reply. Yes, although I tell others to be wary of the build up of fertilisers and thus salts in the soil, I forget that it happens with the natural forms, such as nitrogen fixing bacteria on the pea roots. I have trained the tree now, but I need to lay off the feeding, may take a while to right itself. Thanks again, Vox.

I know how to deal with fireblight in northwest Florida, but what works for me might not be the solution for southern Canada. I know what cultivars are resistant and this is for larger trees. Any tree when it is a recent graft can die, but our rootstocks usually do not and can be regrafted. There are exceptions, but the resistant stop usually stop the fireblight that it does not infect the entire tree. Keiffer pears often gets it, but most mature trees will recover. Less susceptible trees like Orient, Olton Broussard, Southern Bartlett (not a true bartlett), Leona, Golden Boy, Hood, Tenns, Tennoshi, Acres Home, and many other pears for the deep south will handle fire blight. But these pears probably for most of them are too early in blooming for southern canada with the exception likely of keiffer and orient that seem to grow anywhere.

For those that have the time would growing a fire blight immune tree replacing the branches with grafted varieties that are susceptible to fire blight that get fire blight would the fire blight go in to the trunk of the original tree?

How do German Seckel pears typically do, compared to other cultivars? If you have a tree that doesn't seem to be affected that badly, can it be ok, if you remove all the affected branches? I left you a comment on another video yesterday, because I have a German Seckel pear tree that hasn't produced in two years. Now that I'm watching this video, I'm thinking this is probably what's wrong with it. But I don't think it's that bad, though, because it seemed to only be in the branches on one side and the other side was growing and blossoming fine. But that was last year. Hopefully it'll be ok this year too. I'll see what happens in Spring. I also want to get a second pear tree to help with pollination, in case that has been an issue for me, too. What cultivar would you suggest, if I do get a second one? Also, when is the best time of year to cut off the diseased branches, if you're hopeful that you might actually have a pear crop that year? Should I do it in the early spring, before it buds, or after it blossoms?

@@StefanSobkowiak I'll try to do it as soon as the snow melts, then. It's hard to tell where the dead part is, when the tree is still dormant, though.

[@Skashoon]

Perhaps the cuttings could be made into biochar. This returns a waste product into a benefit, permaculture 101. Just a thought. Biochar is then added to compost.

I find it really funny that the KZbin ad that played at the beginning of this video was for an array of chemical pesticides to wipe out pesky insects in one's lawn and garden. 😒😜

[@mujkocka]

How about fire mites cure?

[@StefanSobkowiak]

We had mites, when we took over the orchard. Because we stopped spraying insecticides the predators returned and within 3 years the mites were not a problem.

[@2outta3aintbad96]

Would a really cold winter kill off the Blight. Maybe those affected closer to the winter survive better at being able to out grow it.

[@StefanSobkowiak]

Well we’ve had -38c as our lowest winter temps since I’ve been farming.

[@2outta3aintbad96]

@@StefanSobkowiak Did you notice any difference then summer wise with the Blight after the colder snaps. I also feel once you cut the branches it opens up the tree to the air and more infection. I feel wrapping the affected area in plastic with treatment kept inside the plastic for a few days before cutting might be better to stop the open wound to the air. Or better to cut out the areas in colder climates when the bacteria is most dormant. I am very much more northern than you zone 4/5 and when ever we cut a tree anywhere we still paint the open wound with a non toxic paint to stop any bacteria , fungus, insect ETC to help the tree heal.

[@drewblack749]

As an experiment, what might strengthen those trees such as removing the fruit early on? You may give especially the young ones a better chance of survival. Have you tried this in the past? Thanks for another informative and provocative video.

[@StefanSobkowiak]

Drew Black never tried. You try it and let me know how it works.

Can this happen to avocados? I have had this happening to my fruit trees at home.

[@StefanSobkowiak]

I don’t know. Look up the diseases of avocado. They are far outside our range of trees we can grow.

[@NMW80]

@@StefanSobkowiak yes I will. I also have pear, apple, fig, olive etc too.

[@djangoapple8230]

🤔 my thinking/dynamic thinking could lead me to believe that a fungus could help fight fire blight. However, since you already have it, you'll always have it. My first thought was not depending on fungus at all. If fungus wanted it, it would be there. Looked to me like fungus showed up after the trees were dead. I would use sulfur, zinc, copper, etc.. I have livestock and feed mineral. The label reads like the periodic table. I often point that label out to people and tell them humans need the same minerals cows need to keep them healthy. They look at me like I'm Mork from Ork. People can't make the connection. With the exception of salt, you may want to feed your trees what you feed your cows. 🧐

[@StefanSobkowiak]

More from Ork I see what era you’re from. Exactly minerals are never over abundant or very rarely. They are the core of great taste.

[@gabriellakadar]

Is that why the other chickens were running across in the background? eeek, skunk! Looks like fireblight goes for stressed out trees.

[@supragolgotha6920]

Have ye tried boiling the fireblight and pouring the destroyed bacteria water over the roots to help immunity???

[@StefanSobkowiak]

Never heard of it.

[@lianagilbert61]

can you grow asian pears?

[@StefanSobkowiak]

Yes we have Asian pear, our best growing is 'Taylor'.

[@vf5126]

I’d learned through research that no pear tree is immune to Fireblight, only more or less susceptible. Also, high fertilization (usually chemical) creates larger spaces between cells and allows Fireblight to set in easier. I no longer fertilize my Asian pear with my other fruit trees, and having recovered from F-blight, it’s done well.

[@StefanSobkowiak]

Makes sense, what’s the paper on the research?

[@honestlynate7922]

Where do you get your trees from?

[@StefanSobkowiak]

We grafted our own. Purchased and grew our own rootstock.

Has anyone here used an apple cider vinegar mix spray successfully?

[@StefanSobkowiak]

There is someone from Georgia who’s been using it successfully.

[@nonyadamnbusiness9887]

The problem with letting disease take all the genetically inferior pears is that the cultivars are all genetically identical. There are perhaps a dozen pear varieties and four or five apple varieties that will fruit reliably in north Florida. Seedling pears typically produce tiny hard fruits that even the birds ignore.

[@StefanSobkowiak]

True but they can make great rootstock. If you have the space you never know what surprise a seedling can give.

All you have to do is see it in the future that is healed from fireblight

Blight can be a sign of having sin in our lives, as it can be a curse from God. But if we repent, it should go away.

If God curses those who sin, are you not affected by any hardships? Or are you perfect without sin? An ALL LOVING God couldn't cause such misery.
