Strobe 50WG from Quali-Pro is the generic brand of Heritage WG Fungicide and is designed to deliver broad-spectrum control and prevention of a number of common plant diseases. The product works systemically by being absorbed through a plant's leaves, crowns and roots to put a stop to disease at any stage of its development. Strobe 50 WG comes in wettable granules and is easy to mix and apply. Use Strobe 50WG to treat common diseases like Anthracnose, Brown Patch Leaf Spot and many others.
Tools Needed
To use Strobe WG, you can use either a backpack sprayer or a hand-pump sprayer.
How to Use
- Step 1: Determine how much Strobe 50 WG you will need for your application by calculating the square footage of the area you wish to treat. To do this, measure (in feet) the area length and width and multiply the two values (length x width = square footage). The recommended rate for Strobe WG is 0.2 oz. to 0.4 oz. per 1 to 2 gallons of water to treat 1,000 sq. ft. For example, if you calculated a 3,000 sq. ft. area to treat, you would need to mix 0.6 to 1.2 ozs. of Strobe WG in 3 to 6 gallons of water.
- Step 2: In a hand-pump sprayer, add half of the required amount of water and then add the appropriate measured amount of Strobe WG based on your calculations. Then fill the sprayer the rest of the way with water and agitate until well-mixed.
- Step 3: Spot treat the areas on your lawn where you see the fungal disease. We recommend using a cone fan nozzle tip to get a nice even coating on the infected plant.
- Step 4: Reapply as needed every 14 to 28 days until you no longer see a disease problem. It may take up to two months of diligent treatments to get rid of the disease totally, depending on the disease type.
Where to Use
Strobe 50WG is used to control diseases on turf and ornamentals on golf courses, lawns, and landscaped areas around residential, institutional, public, commercial, and industrial buildings, parks, recreational areas, and athletic fields.
When to Use
Use Strobe 50WG during the growing season when there is disease affecting your lawn, particularly in the summertime when the lawn may be going through stress. You can also apply it preventatively during the growing season.
Safety Information
Strobe 50WG is safe to use when applied according to label directions. Make sure to wear the proper PPE when applying this product (goggles, gloves, face mask, etc). The product is safe for pets and children if used according to label directions. After treatment, keep pets and children away from the treated area until the product dries.
Special Considerations
While Strobe 50 WG can be tank-mixed with other pesticides, it has demonstrated some phytotoxic effects when mixed with emulsifiable concentrates (ECs). These effects are enhanced if applications are made under cool, cloudy conditions, and these conditions remain for several days following application.

No More Pythium Blight
Have tried lots of products before zeroing on this. My problem- Pythium Blight is now solved using this. i had one application and can see huge improvement.
i've previously tried Propiconazole, AZ prop select, Fopshites, hose end fungicide, Scott's granular fungicide with no success. i'll be applying this and Propiconazole (even though it's not working for me) , so that the lawn is does not develop resistance to one fungicide that i'm using. Very pleased with Strobe 50 WDG (Azoxystrobin).

Large Patch in Zoysia
After only two applications I have noticed the Large Patch has stopped spreading. I thought I would be fighting this fungus for much longer than I have. This product performed much better than expected.

Cheaper than the competition
We have been using Heritage for a long time and just switched to Strobe fungicide. It is about 25% less than the Heritage and works just as well.

Q:I have recently discovered I have Bird's Nest Fugus. I am wanting to know the best product to use on this particular fungus before I begin any type of irradiacation by hand. All website information that I have read said to rake the yard to loosen it and then gather it up , but have given no real solutions of a fungicide to use. As far as I can tell if I rake the Birds Nest Fugus the tiny seeds which mimic bird eggs would fall out of the nest please and just start the process over complexly. I live in North Dallas and this spring I had top soil put down so that I could replace the grass in my yard that had died due to the drought. I certainly want to stop this mess, but unsure what to use? Can you help? All suggestions would be appreciated.9/1/19A:I've been using the Systemic RTS Fungicide, for the past 3 years. I did have a fungus on my lawn, which was brown patch disease, and it came back every year, for 3 years. I used this fungicide, and only having to attach it to my garden hose, made if very, very, convenient, for me. Normally, I would spray the fungus, two times, every two weeks. It stopped the fungus, and also allowed the grass, to fill back in, in those large areas that were affected. This year, I only sprayed once, for the entire season, and the fungicide worked, and the grass filled back in. I am impressed with the effectiveness, of this fungicide, and I would recommend, that you give it a try.

Q:How long does it take for the Strobe to be waterproof? Also, parts of the yard are dirt from effected fungus spots. Is it necessary to apply Strobe to the dirt or only area with grass or exposed stolons?7/16/17A:Reapplication is required in typically 14-28 days, you should notice the lawn greening back up after the 30 days. Yes, you should spray the entire yard, soil also. Try to improve the peculation and drainage of the soil in those areas.
