Disease-Ex worked for my lawn
a year ago
I'm located in Northern NJ. In 2024 brown spot devastated my front yard and I had to repair and reseed over 50% of the yard. Again, in early June 2025, I noticed early stages of brown spot and applied Disease-Ex at recommended curative setting. After 1 week, didn't notice much improvement, but fungus did not expand. Second week I noticed some improvement and same in 3rd week. It's now the 4th week and it's all gone and green grass once again! I plan to apply another application in a few weeks as preventative. I got lucky and caught brown spot early on.
I also stopped using my E-Go electric mulching mower as not to spread fungus to other parts of the yard. Last 4 weeks I have been using my Honda mower and bagging. All good now and very pleased with my actions and Disease-Ex.

Doesn’t do what it says - stay away from it
a year ago
I used this product and I’m actually afraid that it killed my grass instead of reviving it. I have never had the brown spots and patches that I do now since using this product. They multiplied. Absolutely disgusted by what has happened since applying this to my lawn, never again. Now I have to go spend MORE money to get a better product to fix the damage that was done by using this stuff. Stay far away from it or you’ll regret it.

Scotts DiseaseEx Lawn Fungicide will not reverse damage already done, but will prevent further damage when applied at the curative rate. If conditions do not improve, it may be that the fungicide will not control the specific disease you are dealing with. You may want to take a small sample of the affected area to a certified nursery person to have the disease properly verified. As long as favorable conditions exist for disease (typically high humidity or moisture and heat), you can repeat applications every 14-28 applying no more than 37 lbs of product per 1,000 sq. ft.

Best insurance for preventing thousands in re sod
a year ago
Disease will kill your St Auugustine lawn. Then the bugs come to finish it off. I use Disease X so this doesn't happen. Stops existing scourage and prevents damage to replacement turf. It's what you need 'cause the spray companies do fertilizer and weed killer but NO disease application.

After applying I noticed incredible improvement within 5 days! Brown patch was spreading like fire from the neighbors lawn, this product stopped it immediately and it’s getter better and darker green everyday.

Disappointed

I purchased this product to combat red thread disease. I used Scott's Elite spreader to apply at the recommended setting. The product is either too dense or slightly damp and would barely discharge from my spreader. I am considering whether to return it to the store for a refund.

Any moisture that gets in the product will make the granules lump together and then when it dries out it forms hard clumps. If the product is completely solid and cannot be easily broken apart, we recommend disposing of product. It should not be used because it cannot be properly applied.

Consistent results that work
2 years ago
I always apply this in the early spring, and then every 30 days afterwards until about the end of September, my lawn stays consistently green without any diseases, before I use this, I used to have problems with yellow spots and areas that would just die off. Since applying disease-ex , People are always asking me how I get my lawn to look so good. I just tell them I’m using the Scott’s product according to the directions, my lawn looks consistently better than all my neighbors who allow their gardeners to apply whatever unknown products. I cannot over emphasize the importance of disease-ex in maintaining healthy And vigorous grass.

Coverage rate untrue
2 years ago
Coverage rate of 5,000 square feet not even close. One bag at preventative rate (5,000 sq.ft.) barely covered 2,200 square feet. I used a Scotts drop spreader and the calibration is correct. I know it depends on how fast you walk (and I walked fast) but I must have needed to run like an Olympian.

SAVED ME THOUSANDS OF $’s!
2 years ago
Two years ago, after my lawn care service insisted I needed to water more, more, MORE— I had my Extension Office come out and look at what was left of my normally beautiful yard. Through testing it was determined my yard, and that of my neighbors, all had FUNGUS. I lost more than half of my yard. My father, God rest his soul, always used Scotts products as a greenskeeper. So that’s what I did—bought Scott’s DISEASE EX and applied as instructed. I was certain I was going to have to sod— many of my neighbors did. But this is spring of the second year and my grass has come back beautifully.

Hasn't worked

A week ago I applied the product with rotary spreader. It rained within an hour of application so I know it was watered. It has been over a week and the weeds are thriving, No sign of wilting in the past 10 days. The small flowering weed I have may not be on the list. Will try another product.

While it does not need to be watered in immediately, Scotts DiseaseEx must be watered to activate the product. The sooner the product is watered in the sooner it will begin working. We have escalated your label complaint.

Finally resolved my brown patch issues
2 years ago
I have struggled with brown patch for 5 years now. We live near Houston and last two summers have been hotter and more humid than normal. I started applying DiseaseX in early June and set an alarm on my phone to reapply every month. It’s end of November and so far, so good. My whiny neighbor got hit hard and blamed me for the brown patch. I have been delighted to see that what she’s using didn’t work nearly as good as my monthly application.

Did not work

I applied this twice during September 2 weeks apart. Both times watering it as directed. There is no noticeable change. I must note that the first bag contained a very dark brown granule. The second bag bought two weeks later was more lighter in color (gold?). Not sure why this was.
I cannot recommend this product. I will wait until spring and pay a professional company to treat these large areas in my front yard.

Worked well for me in Missouri
2 years ago
I bought the 5000 sq ft bag. Worked well for me, considering the alternatives compared to what this bag costs it was worth it just to try. Almost 1 month later the brown spots are recovering well and my lawn seems to be doing much better. Even if you read the reviews some say it works some don't. For me it did and for the price even if it didn't work it was still worth trying to help save my lawn. Worthy to note, I live in Missouri. Only thing I can agree with others on is with the broadcast spreader suggested amount and what the bag is rated at for coverage doesn't seem to be accurate, coverage doesn't seem to cover as much as the bag says. Either way still worth every penny! Wish I would have taken some before photos so I could show comparison.

Scotts DiseaseEX certainly did not cure but make worse. My lawn is now a total disaster. My lawn was beautiful and green. One day I saw 1 big yellow spot then I quickly applied DiseaseEX to the entire lawn. It turn out worse than ever. My lawn is now 90% yellow.

Cured rye grass brown patch.
3 years ago
My perennial rye grass lawn had brown patches and looked awful. I fertilized and treated for grubs and insects. No improvement. After using this product, and over-seeding the dead areas, the grass is finally reviving. I applied an initial application and then a second application after four weeks. The before and after difference is remarkable.

Works when you follow directions
3 years ago
These reviews are funny…product works great if you use it the way they tell you how to. I need to use this every year as my lawn is susceptible to disease. I usually catch it after it appears so I mostly use it as a curative and not a preventative. I’m not convinced that the early application would prevent it…but I’ll try in the spring. I have 1/2 an acre so this is not a cheap application…

Not Sure about DiseaseX
3 years ago
I have new Zoysia sod put down in March this year. Brown patch started showing in late May.
Have put down 2 applications based on Scott's instructions. Does not seem to be getting better.
Sod is still covered in brown spots. So I am not really sure DiseaseX actually works.

We're sorry to read about your disappointment with Scotts DiseaseEx Lawn Fungicide and appreciate your feedback.
Affected grass may have been dead or severely damaged by the disease prior to application. This product will not cause dead areas to recover or reverse damage already done by the disease prior to application, reseeding is necessary once the grass dies. If the problem persists, it could be insect damage and not a disease. Please contact your County Agricultural Extension Agent to properly identify the problem. Additional application may be needed to fully control the disease if it is severe. Repeat application every 14-28 days while conditions favorable for lawn disease exist (no more than 37 lbs. of product per 1,000 square feet). Please note that this product should be applied to the entire lawn and not just the diseased areas or the disease may spread.
