Controlling scab and other fruit tree diseases

A tutorial to help understand and control fruit tree disease issues in the orchard.

[@aeastman59]

I appreciate your warning people about sprays and our honeybees that we also need to protect!

[@user-gl9nv5ix8e]

I have to say that this video is the best video when it comes to taking care of your fruit trees. I'm new to this and I planted 10 fruit trees on my property last year. When I was researching how to take care of them all I found was a 3 minute video that didn't explain much and didn't make a lot of sense. Until I found your video. Thank for taking the time to explain everything I need to know, what and why I need to do what I have to do to keep my trees healthy and happy to produce the most and best fruit possible. Thanks again. Jim from charlton ma.

[@healthyhorticulture]

Thanks for watching!

[@TheWisendorf]

This is such good and common sense stuff here that I can not add anything other than my own failures. Witch are taking notes cause I forget and being consistant. Also get your self a really decent sprayer so you can get really good coverage. Hit and miss areas just doesnt work very well. I got lazy and did not prune my apple tree last fall. It was just to congested and turned into a massive infestation of several things. Best advise I could give is find a grower like you and beg for a job even if you worked for free.

Great video! I’m curious what your results were with the Thyme-Guard product? I’m preparing to start an organic spray protocol this year and want fungicide that follows suit.

[@geporras99]

I bought a house with fruit trees that were not taken care of by previous owner. I was so excited to see apples only to find that pretty much all of them have spots (or scab). Should I cut the fruit off the trees and throw them?

[@tomsweet2072]

Hello I didn’t hear you using dormant oil spray. I might have missed it if you did. I live in southwest Michigan and last year had scab on the fruit. Nice information you presented. Thanks Tom

[@healthyhorticulture]

Dormant oil is an insecticide but has shown some efficacy against powdery mildew. I will use it if I’ve had issues with certain insects like spider mites, scale or aphids. Glad the video was helpful

[@ndbkjalvarez9619]

Thank you so much for the info. brother. I had this problem with my apple trees for a few years. I can't wait for the spring to come so I can take care of my apple trees.

[@leonglassglow3854]

This is my first year at growing apple trees and this tutorial was very helpful. Right now all 3 of my apple trees have cedar rust, I think. I'm having a hard time identifying the type of disease they have. I just hope they make it until next spring when I have the knowledge to care for them. I appreciate your sharing of knowledge, but I did find your video a bit hard to watch. I'm 67, and still at my old slow age. I found your explaining too slow. I sped it up to 150% and then its perfect.

[@AstroRef68]

Thanks so much. Excellent explanation.

[@junemaeven]

We moved into an older property with gorgeous apple and cherry trees. The cherries are spectacular and we haven't had to do much but ask the crows to share! But, the apples are riddled with scab. Listening to getting ahead next spring sounds like the only solution now. In the meantime, I have questions for anyone who can help: 1) I'm in the PNW, and the rain season is Oct-June, so when do I spray? Apples are still on the tree in Sept and our silver tip season occurs at the same time of our constant rain season. 2) There is a lot of lichen on our tree trunks and boughs. Should I be concerned about this? Many thanks from this newbie!

[@marktapley7571]

Can dormant oil be used all through the spring until it gets too hot. Also have had lots of trouble with stink bugs on fruit. Please give recommendation.

[@carolfackler2339]

I thought I had apple scab last year for the first time on an espalier multi-grafted apple tree, but I just learned about bitter spot, and now I am not sure which I had. There was one variety that didn't have the spots at all. Would bitter spot affect all the fruit? You have explained the fungicide application better than any video I have seen!

[@healthyhorticulture]

Which varieties where infected and which variety was not. That might actually help with diagnosis

[@saraloggins8365]

Could you grow thyme as a living mulch under the tree to help?? Just curious. I love creeping thyme and I have a ton of it!

[@bobm3957]

I live in what used to be the apple orchard capitol of Connecticut and unfortunately have an old abandoned orchard behind my property, there are still trees producing fruit and I wonder if I'm fighting a war that can't be won with all the spores. I do get some decent fruit but it's an endless battle. Great videos though, easy to follow vs the university pages and many others

[@healthyhorticulture]

That sounds like a fun project, there’s something special about restoring an old orchard. Shoot me an email…[e-mail]. Maybe I can swing over and take a look. This orchard was abandoned for several years before I stepped in. m.kzbin.info/www/bejne/oZe2mZaGmJmspMk

[@gailciborowski5184]

I'm in Michigan and listened to your video's and have a quick question. If last year we had problems with scabs and did the cultural preventative maintenance so far for this year (it's February), do we also spray the fungicide on the ground below the tree, when spraying in the spring?

[@healthyhorticulture]

No, concentrate your fungicide sprays on the tree itself.

[@janettehosein7170]

What do you do when live on Vancouver Island and it basically rains all winter and spring? I got scab for the first time last year on my Granny Smith, my pink lady had lots of blossoms then started getting black spots and fruit developed tiny little swells then fell off my tree, my honey crisp was beautiful they are in a row about 15-20 ft apart plus I’m an organic gardener. Any suggestions greatly appreciated. I have bark mulch under my trees so very hard to keep leaf’s away

[@healthyhorticulture]

I just put together a video to answer your question, I should have it up tomorrow night.

[@barbarasimoes9463]

I'm wondering if planting thyme around apple trees would help. It is naturally low-growing, and if its essential oils are used in a spray, it would seem that the plant itself might be beneficial. Thank you for your clear explanation and images for timing. I have an ancient apple tree in the back yard. I've always just mowed in the leaves and drops. This probably isn't the best idea, huh?

[@healthyhorticulture]

I’ve contemplated this myself. I believe that thyme and oregano as well, have a particular terpine called carvacoal which is known to be antibiotic, anti microbial etc. there are a few thyme based products out there but I have not yet used them. Not sure if planting them under your trees would have any real benefit in that regard but it certainly wouldn’t hurt to try.

[@healthyhorticulture]

As far as the mowing goes, yea cleaning up any infected plant material would certainly reduce disease pressures to some degree.

[@swannoir7949]

I've been told to plant thyme, oregano, onions, and marigolds around my apple trees. I'm defending going to try that.

[@WallyTony]

My apple tree is ravaged. Problem is it's next to my neighbors drive and they have little kids so I don't want to spray anything.

[@MrHoovdog]

This was very helpful. Did you have the link to the chart for spraying you spoke of in the beginning?

[@healthyhorticulture]

Sure, it’s called an Apple scab mills table which basically tells you how many hours of moisture are necessary under different temps for the scab to spread newa.cornell.edu/index.php?page=revised-mills-table

[@MrHoovdog]

@@healthyhorticulture thanks!

[@MrHoovdog]

@@healthyhorticulture So I live near Chicago and we are supposed to get some rain this weekend. Theres still snow on the ground and temps are slowly creeping up but still below freezing at night. Should I be putting on the mancozeb now or wait until the trees start waking up?

[@healthyhorticulture]

Wait until the trees wake up, once the buds start to swell, then start looking at the weather and thinking about spraying. Here in CT it’s usually around mid April.

[@MrHoovdog]

@@healthyhorticulture OK thank you

[@andrealovette]

Are fungicides safe? What is a natural treatment thats safe?

[@aaronmiller3138]

Hello I have 3 apple trees, I want to spray them with bonide mancozeb how much do I mix in a gallon of water? The label sucks! Thanks great video I’ve watched it 3or4 times.

[@healthyhorticulture]

Yea, those labels can be tricky, assuming that your product calls for 4.8 quarts per acre that would be the equivalent of 3/4 of an oz. Per gallon of water.

[@carriesmith-th9et]

What about neem oil love from Ireland

[@pfurr281]

Do you spray the products even if there is no rain but the tree is ready according to blooms in the Spring?

[@healthyhorticulture]

Not usually, without rain you really shouldn’t get much fungal movement. If we went a long period of time without rain I might spray if we are dealing with very high humidity.

[@pfurr281]

@@healthyhorticulture Thank you for the information I am going to do this this year and hope to get some nice apples.Thanks from NC

[@marinbalan352]

Is daconil fungicide comparable with captan? Thanks

[@healthyhorticulture]

They are comparable in the way that they work and that they are both pretty broad spectrum fungicides that work as protective fungicides, not curative. In a perfect world they should be applied before a rain event occurs to protect your trees from infection. Make sure to read and follow the label directions and follow the days to harvest interval.

[@kathymichael6499]

Wow! I really like how you explain things! I have a lot of questions, but I'll just ask two for now. 1) My apple tree is flowering and my apricot and plum trees are just starting to bloom. I live in Southern California. What would be a good choice for spraying now? 2) What kind of mulch do you think is good under these fruit trees? THANK YOU SO MUCH!

[@healthyhorticulture]

If the trees are in flower you probably should wait until petal fall. Once most of the blooms have fallen a combination product such as bonide brand orchard spray should be helpful. Keep in mind that I’m on the opposite corner of the country so things might be a bit different in your neck of the woods

[@healthyhorticulture]

As far as mulch goes, I prefer plain old wood chips, like from a wood chipper, with a bit of grass clippings mixed in but any natural organic product is certainly better than no mulch at all.

[@daniloribeiro8144]

I have a bad scab problem as I fallow your advice I would like to start my application early on silver tip, on my fruit trees, my question is do I have to wait for a certain temperature?

[@healthyhorticulture]

Scab starts to become a concern at temps above 50-55F with good rain.

[@MattyDemello]

So, should someone spray a fungicide like the one you have here once every 14 days for apples? I sprayed mine once at Silver Tip and another at green tip. Now they're at tight clusters. No pink seen yet. Should I spray them again? like now. should I spray up until flowers start opening. Then restart once the flower petals fall?

[@healthyhorticulture]

Yes, tight cluster and pink are typically when they are most prone to infection. Once most of the flower petals fall off you probably want to use an insecticide as well as a fungicide. Right at petal fall is when the curculio insect starts to attack the actual fruit. m.kzbin.info/www/bejne/qn_WimtmbNOFr7s

[@MattyDemello]

@@healthyhorticulture awesome. Thank you so much. It's nice getting a little advance from people who have done it a while and know. Thanks. I sprayed again today.

[@gcgopro6912]

I have a large crab apple right next to my new small orchard. Too big to spray and loathed to cut it down. Third option?

[@healthyhorticulture]

Yea that’s a tough one, use strong cultural controls cleaning up fallen Leaves and fruit to help reduce disease pressure and be persistent in protecting your fruiting trees

[@gcgopro6912]

@@healthyhorticulture Thanks. Good idea and I shall do it!

[@brianfaust2449]

Can you use Mancozeb after bloom? I use it before bloom, but then switch to copper, immunox, and captan? I rotate every spray...

[@healthyhorticulture]

You can use mancozeb after bloom but be aware of the pre harvest interval. On the commercial stuff it’s 77 days between spraying and harvesting. I will sometimes use mancozeb at my petal fall app just after bloom but then I switch over to captan which has a much shorter harvest interval. Spraying copper after bloom can create a russeted fruit. I usually don’t use copper after tight cluster or maybe early pink. Captan or mancozeb, mixed with immunox, will give you much better scab control than copper.

[@isaacliu9661]

What is the mixing rate of Mancozeb per gallon for apple scab? The product label says 3.5 fl oz / 1000 sq ft. Some people say 1000 sq ft = 1 gallon, is it correct?

[@healthyhorticulture]

I hate when labels are listed that way. It can make things quite confusing. What brand of mancozeb are you using? I can look it up and try to figure it out for you.

[@theguineapigchannel]

Hello! I wanted to know does black knot affect red delicious apple trees?

[@healthyhorticulture]

No, black knot affects stone fruits like cherry, plum, peach, apricot and nectarine. Apples are in the pome fruit family

[@theguineapigchannel]

Okay thank you so much!

[@melvis2017]

Great informations thanks 4 that

[@AstroRef68]

1. Do you think mulch hold funges should I avoid mulch? 2. Can I combine different spray like agrocultural oil spray? 3. Can I continue funges spray as continued fruit tree spray after petar fall

[@healthyhorticulture]

1. yes, mulch can and will hold fungus. 99% of fungus is beneficial to your soil and your plants. 2. there are several pesticides that can and are often combined but Captan should NEVER be combined with any oil based products. 3. yes you can and probably should as long as you follow the "days to harvest interval" which should be stated on the label.

[@anthonylew989]

👍♥️

[@thomasmurray5193]

Is sulphur also good to fight against apple scab? Thank you

[@healthyhorticulture]

Lime sulphur can be used for scab. It’s not as effective as mancozeb but if you have your cultural controls in place you may find that it offers sufficient control and it’s a nice organic alternative.

[@MattyDemello]

1 more question. Sorry, lol. Is Mancozeb ok for Peach Trees & plum trees too? Thanks.

[@healthyhorticulture]

I don’t think mancozeb is labeled for stone fruits (peaches, plums, nectarines, cherries). But check the label. If it’s not labeled for stone fruits look into products containing chlorothalonil. I believe they are commonly labeled for such. This would include trade names like “daconil” or “fungonil” as a replacement for mancozeb on stone fruits

[@MattyDemello]

@healthyhorticulture awesome. Thanks. Ya I thought it was more for Apple trees. Good to know.

Pine trees are not an issue at all, cedar trees can be an issue depending on exactly what type of “cedar” they are.

[@healthyhorticulture]

It really depends on your specific situation. If you didn’t have an issue with disease last year there may not be a lot of fungal spores on the fruit that was left on the ground. On the flip side, leaving fallen fruit will decompose and add some fertility and natural sugars to the soil which can be beneficial.
