Description

Protect your tree and plant investment!

Mix 1 tablespoon of dry concentrate per 2 1/2 gallons of water to your apple and pear trees at the beginning of blossom-time to control bacterial issues like fire blight. Repeat applications every 3-4 days until bloom time ends. Apply an additional spray 5-7 days after blooms end, when weather conditions favor the spread of diseases such as fire blight, bacterial wilt, stem rot, leaf spot, and crown gall. Do not apply when fruit is visible. May also be used on roses.

Why did you choose this?

Desperate to control fast moving fire blight.. TBH already ordered another tree to replace but worth a shot to try to save it.

I have cedar trees close to my apple and pear trees. Want to prevent fire blight.

I have fire blight on young pear tree.

I have young pear trees and want to protect them from fire blight.

Should this product be used on recently planted apple trees?

I follow my University of Kentucky spray schedule for home fruit growers,
which tells me that pome fruits (apples and pears) need to be sprayed for fire blight. IT is an especially serious disease on these fruits, and that I should keep up with the recommended sprays from the time I plant my new Stark trees, not wait later in the year or the next year. I just sprayed again today with Ferti-lome Streptomycin. I have 34 trees from Stark and always follow my State recommended spray schedule. Stark has the right products for the backyard fruit grower and they give outstanding advice as well. R.S.

how much powder in hose end sprayer?

There are no exact instructions for use in a hose end sprayer, but here is a link to the label, perhaps this will help: //www.fertilome.com/ProductFiles/10363%20Fire%20Blight%20Spray%202oz%20ALL.pdf

will it work on trees that already have blight?

This spray is recommended for use in early spring when the trees are blooming and just after the bloom period. If the trees already show signs of fire blight, it's best to prune out the infected wood, making sure to disinfect the pruning tool between each cut.

my santa rosa plum was loaded with blooms, i sprayed it with the fire blight solution and within a couple of days all the blooms looked like they had been singed by a blow torch. would this have caused the blooms to turn brown?

I used ferti lome fire blight spray last year to spray 8 apple and pear trees that had a terrible problem with fire blight. I sprayed them twice, once at full bloom, then again about a month later.
There was no blossom wilt or any negative effects on the blooms on any of the trees that I saw. The fruit did well on all of the trees.

Without a doubt, the spray dramatically reduced the fireblight damage, especially to fruit set. There was still a few patches of fireblight to foliage in late summer, but it was minor compared to previous years.

will this product effect honey bees?

It is an antibiotic, because fire blight is a bacterial infection. To my knowledge it won't hurt honey bees, and i sprayed trees in bloom with it, but you may want to check with bee experts or county extension offices. It contains streptomycin sulfate, which is a strong antibiotic.

do you spray while trees are in blossom?

The label states: To control Fire Blight in home plantings, apply 1 tablespoon in 21⁄2 gallons of water (equivalent to 100 ppm or 4 ozs. per 50 gallons of water) in foliar and blossom sprays. Make first spray at the start of blossoming period. Continue spray applications every 3 to 4 days during bloom time. Apply additional sprays every 5 to 7 days after blossom period when weather conditions favor spread of Fire Blight. Do not apply when fruit is visible.

Can I use this along with copper to treat apple and peach trees, and ornamental crabapples?

Yes but I assume you mean in an alternating spray regimen. I would not double up and spray together. Fire Blight is nasty stuff and not cured. Pruning diseased limb tips is part of the solution. I found spraying several times at pink tip and then while open, reduced infection significantly using Fertilome. If growing different varieties, you may have distinct bloom periods which complicates and extends spring spraying. You can buy newer varieties that resist FB but the fun for me is growing heirlooms and there lies the problem. The Fertilome product is pricey if you have many trees to treat. Have not tried white vinegar (2 cups/gal) and some say it works. To keep costs in line, I will try vinegar this fall and spring 2021. I will also experiment with using MILSTOP as an alternating companion to vinegar. Milstop can be used without health concerns.. Terry

can I use it after apple tree flowering?

Fire blight is a bacterial disease which typically infects trees via the flowers by insects spreading it. Therefore, one can prevent infection by spaying with antibiotic during flowering. After flowering, when infection already occurred, one treats the disease. The latter is possible with frequent spraying (every few days and after every rain), combined with cutting away infected branches. I suggest cutting away infected parts at the first sight of infection (leaves hanging down), well below the affected area to stop further spreading.

how often should I spray it to my young pear tree?

I spray just as my tree begins to bloom, again when it is in full bloom, and
once more as most of the petals are dropping. If there is a heavy rain during
this time, I reapply. If fire blight appears during the summer, I cut the affected branch off several inches below the diseased area and apply then.

Please clarify the instructions to “Apply an additional spray 5-7 days after blooms end, when weather conditions favor the spread of diseases…” should the spray be applied before the rain starts? Immediately after? Or just at a 5-7 day cadence?

My trees had a bad case of fire blight and had no apples. I sprayed at 5-7 day intervals through out the season as I live on Cape Cod and have high humidity and frequent fog.
I spray during the day with plenty of time to dry before moisture of any sort. Since then the trees were attacked by the Winter Moth larvae which gave me no flower buds. Why do I bother.

Treating Asian pears.
My pear tree always has fire blight, prune, burn the cuttings and nothing seemed to work. Started spreading to the apples. Sprayed this spring during full bloom and can't find any blight on any trees. Plan to spray again next spring just to be sure.

Seems to be working
Our trees are not yet infected, and I want to keep it that way using this product. My neighbor's apple trees are infected as well as his Bradford pears. I sprayed his trees early last year with the Fertilome product, and they were doing better by fall.

Didnt think it would work
Pear trees were curled up and burnt last season. I almost cut them down since I read they would just be a loss and I saw a little leaf curl early Spring. Checked the reviews on this product and tried it. Glad I did.

I cut all limbs close to tree. Then sprayed liberally in each cut.

Now both trees are leafing out perfectly with no sign of fire blight.

I will keep u posted. But so far so good!

Fertilom Fireblight powder
None of the stores in Memphis or Shelby County sells this product !!! It controls fire blight on my pear trees VERY well. All of the big box stores don’t have it and they sell pear trees that can be infected by fire blight ! I guess customers don’t get respect like they did in the old days! Thank you Starkbros for caring about us , your customers!!!!

Its worked for my apple trees!
I've cut the affected branches of my apple tree, then sprayed it with this and didn't have Fire Blight from that moment (two years ago). The tree is doing great - it is growing!

Blight spray.
Here in New Jersey I have to keep on top of prevention of fire blight on my apples, pears and Asian pear trees. This product goes a long way, is easy to use, mixes well in the sprayer, and is a MUST as a spray.

Fire blight spray
Fire blight can occur in many fruit trees and once it happens the only solution is to cut out the branch taking care to avoid contact with other branches if possible and then spray the tree,. Now I spray once in June and again in July for prophylaxis this avoiding limb loss.

Fire blight spray.
This stuff has been a lifesaver for my trees & it also saved 2 of my josta-berry plants. Fire blight can kill a 3 year old tree is less than a week. If you have it , get this and use it....you won't be dissapointed and can see the results in just a few days.
