Disease-Ex worked for my lawn
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.

Expensive with mixed results
Not completely effective. I have applied it twice at the treatment dosage. Some areas have had zero improvement.

Doesn’t do what it says - stay away from it
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.

Product not effective
I bought this for dollar spot fungus. This product comes up as an option when you search for a product to address this type fungus. Unfortunately a waste of money. Today I bought a competitive brand. Hopefully have better results.

At best an average product.
I applied this product early May; it’s now 4 weeks and my grass is still fighting disease. I’ll try one more application and if it helps before putting Scott’s summarizer down.

We're sorry to read about your disappointment with Scotts DiseaseEx Lawn Fungicide and appreciate your feedback. 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. We want you to be confident in our products. For this reason, we offer a product guarantee. If for any reason you, the consumer, are not satisfied with the results after using this product, you are entitled to get your money back. Limitations apply.

Best insurance for preventing thousands in re sod
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.

This product is absolutely incredible!
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. Cannot wait for 14 days to reapply and continue to watch it improve. Tried everything and every brand this is the end all to the fungus!

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.

We're sorry to read about your disappointment with Scotts DiseaseEx Lawn Fungicide and appreciate your feedback. 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. We want you to be confident in our products. For this reason, we offer a product guarantee to our consumers. At your earliest convenience, please reach out to us at 888-270-3714 if we can further assist.

Consistent results that work
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
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.
