Should this product be used on recently planted apple trees?
Tim N on Apr 22, 2016
BEST ANSWER: 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?
Brenda R on Mar 1, 2017
BEST ANSWER: 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 this product effect honey bees?
Susan C on Jun 30, 2016
BEST ANSWER: 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.
will it work on trees that already have blight?
Cheryl K on Jun 29, 2016
BEST ANSWER: 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?
maggie on Apr 18, 2016
BEST ANSWER: 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.
how often should I spray it to my young pear tree?
guo l on Apr 9, 2018
BEST ANSWER: 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.
how long is the ferti-lome solution stable after adding to water?
tom o on Feb 11, 2018
BEST ANSWER: I contacted the company and they said it could be kept a couple days at best. Hope this helps.
Can you use this product in the fall on just planted pear trees?
Teresa F on Sep 28, 2017
BEST ANSWER: According to the label, you should first apply it during bloom time. Here is a link to the label: //www.fertilome.com/ProductFiles/10363%20Fire%20Blight%20Spray%202oz%20ALL.pdf
I was going to apply this with a backpack sprayer. Is this product considered a wettable powder that is best used with a diaphragm pump in lieu of a piston pump? Any advice would be appreciated.
DENNIS C on Jul 31, 2016
BEST ANSWER: Used a 2 gallon pump up hand sprayer for every application. Worked fine in that. My father also used the product in an avt diaphragm sprayer worked well in that also. A backpack sprayer should do fine for normal applications.
If you spray ferti-lome fire blight spray on pears can they be eat after 3 or 4 weeks later?

My pear trees have fruit but disease is spreading fast. Can I still apply product and what are consequences?
A E on May 24, 2018
BEST ANSWER: Yes, but you MUST prune away and sacrifice the diseased branches. Use sterile procedures...wipe your pruners with bleach, Pinesol, or alcohol with EACH cut. I know it's a hassle but you do not want to infect healthy portions of the tree. Bag up all debris and dispose of it. Do not put it in your compost pile or brush pile...that only allows it to continue to thrive. Spray the ground below the tree too. If you notice a lot of ants in your tree, apply diatomaceous earth around the base of the tree. It will keep them from spreading the disease. You will need to reapply the spray according to the instructions on the container...I think it was every 10 days to 2 weeks. The company's website is very helpful.
do i spray the whole tree, trunk leaves over and under?
joe s on Apr 25, 2018
BEST ANSWER: This is a contact spray, not a systemic. You need to spray the whole tree and make sure you remove dead/diseased branches, leaves and any debris from under the tree.
I have a mature pear tree (variety unknown). Since it's so tall, how do I reach the top to spray??? Thanks.
Donna E. on Mar 24, 2018
BEST ANSWER: I can get high enough using a 6' step ladder and a 2 gallon sprayer that can be pumped up to 40 PSI. Just make sure there is no breeze to get the best coverage.
How effective does this compare to Serennade? I have been using Serenade on my Asian pear trees.
yaau c on Mar 8, 2018
BEST ANSWER: I thought that it was very effective. It is very important that the spay be applied during the correct bloom time and in the correct dilution.
Will this be effective on grapes that show definite signs of fireblight or some kind of scorch?
Elizabeth B on Sep 10, 2017
BEST ANSWER: Yes, it will most definitely help. Please do follow the directions exactly; it can be tempting to overdo it, thinking that more spray will be more effective, but just the opposite is true.
Will this product work for bacterial leaf spot i have on pear leaves?
sunnyjay on Jun 29, 2017
BEST ANSWER: Yes. According to the product label this spray is used to control Fire Blight, Bacterial Wilt, Stem Rot, Leaf Spot, and Crown Gall on fruit trees, flowers and shrubs.
Why can't I spray ferti lome when fruit is visible?
McKinnon on Apr 30, 2017
BEST ANSWER: This spray is effective against fireblight when the tree is blooming, since the blossoms are the most susceptible to bacteria and the most efficient way for the spray to control the issue. You should not even be using this spray when fruit is visible.
Active ingredients?
Donna C on Mar 24, 2017
BEST ANSWER: The active ingredient is streptomycin sulfate (an antiobiotic). Here is a link to the product label: //www.fertilome.com/ProductFiles/10363%20Fire%20Blight%20Spray%202oz%20ALL.pdf
I have some mature trees that are rather tall thus a hand sprayer may not be as effective as a hose sprayer where i can reach the top of the trees. Is this product suitable for such an application?
Frnak N on Mar 21, 2017
BEST ANSWER: You can use a hose-end sprayer, but still be sure to follow the mixing instructions. A little goes a long way and it's easy to mix more than you need. A gallon of spray can provide adequate coverage for a semi-dwarf tree (12-15 feet tall).
Do you know how many table spoons you get out of a 2 oz container of ferti-lome?
James H on Mar 1, 2017
BEST ANSWER: You would get four tablespoons our of two ounces.
Are the tablespoons to be level one or heaping? also, once mixed how long can you store it in the sprayer to be used 3-4 days later.
Conley P on Feb 23, 2017
BEST ANSWER: The measurement should be level. Once mixed, it will not keep long because it contains an antiobiotic that will deteriorate. Mix as needed and be sure to follow the package directions.
Is the fruit edible if it was sprayed a month before harvest?
Weeze on Sep 13, 2016
BEST ANSWER: According to the label, this spray is not intended to be used when fruit is present. I would take that to mean that the fruit should not be eaten if the fruit has been sprayed.

Fire Blight
Did a great job controlling fire blight in my flowering pear trees. I have to spray at the beginning of new season but slowly the fire blight is almost gone. At least, I have saved my trees and did not have to cut my trees down as I was told by local garden shop.

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.

Great product and service
I ordered 3 for the discounted price. The product is just what I need and I'm grateful for a great company like Stark Brothers to buy it from. I chose Stark Brothers not only for a fair price, but to support a 200+ year old nursery business .

Fertilome Fire Blight Spray
This spray is expensive to use for our 34 fruit trees, but if you don't use it as one of the Fire Blight deterrents, you probably will have problems you wish you didn't have.

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.

Doesn't desolve
Like my title. This product does not dissolve in water and we had to constantly agitate the tank to keep the particles suspended. Other fire blight applications are much better then this.

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!
