What is Fungus Fighter?

Uncle’s granular Fungus Fighter provides control of the most common diseases in turf including but not limited to Brown Patch, Powdery Mildew, Pythium, Summer Patch and Dollar Spot in Kentucky bluegrass, turf fescue, rye, and zoysia grass. As spring evolves into summer bringing warm nights and high humidity. Patches, spots, eyes, and slime show up in the lawn quicker than a chicken on a June bug.  Lush spring growth is particularly susceptible to lawn diseases when those first warm, muggy days in May and early June arrive.

Hot, humid temperatures mean disease and fungus in your yard. Managing disease in turf starts early in spring – lawn spots are a lot easier to prevent than control.  By applying granular Fungus Fighter, we can protect the lawn before pathogens get into the plant and wreak havoc.  Shaded areas are of particular concern. Restricted air movement and humid conditions will stimulate turf disease. Grass Pad’s Fungus Fighter allows a healthy lawn to outgrow many of the diseases that show up.

What Does Fungus Look Like?

There are several different types of fungus that can appear in your lawn depending on your conditions and the type of grass you have. There are a couple of the more common varieties below. If you’re concerned about whether or not you have fungus in the yard, bring in a sample to our lawn experts and we can help identify the problem!



Uncle’s Tip: Mushrooms are a sign that your soil is alive and doing well. Mushrooms grow on decomposing organic material in the yard, such as a dead tree roots and buried wood scraps, and are unrelated to the lawn diseases we’re discussing here. If you’re concerned about a child or pet consuming a poisonous mushroom, then physical removal is recommended.

The Fungus Fighter Advantage

Fungus Fighter is the complete strobilurin fungicide specifically engineered to provide protection against many of the most destructive turf diseases. Each Fungus Fighter application provides systemic preventative and curative control for a broad spectrum of turf diseases. Treating lawns with Fungus Fighter is an excellent foundation for disease resistance management strategy. Root systemic activity allows grass plants to take up Fungus Fighter and provide protection against invading fungi from within the plant.

How Do I Apply Fungus Fighter?

Fungus Fighter is a granular application. No hoses or sprayers required, just use your broadcast spreader. Each bag of Fungus Fighter will cover approximately 4,000 to 8,000 square feet contingent on curative or preventative rates and application intervals. Fungus Fighter should be watered in within 24-48 hours after application.



What to expect from Fungus Fighter?

Have reasonable expectations after an application. Fungicides are used as disease suppressors. When applied as directed, Fungus Fighter will stop the spread of most common turf diseases. However, Fungus Fighter will not change brown or yellow spots to green. Regular lawn maintenance, re-applications of Fungus Fighter, and routine fertilization will be required to rebuild healthy grass to grow out of the disease. Spot repairs or heavy overseeding may be necessary.

Turf disease in Bluegrass Lawns

Bluegrass diseases show up in the form of a slime or dust that wipes off, or even a patch that seems to die overnight.  Apply Fungus Fighter in Late April to Early May when bluegrass is looking its best. Extend control by applying Fungus Fighter at 21 day intervals when conditions are favorable for disease.

Uncle’s Tip: Mow bluegrass shorter in the spring and be vigilant in the areas under trees or on the north that seem to hold the heavy dew longer in the morning. Mow the lawn shorter while it is cool, and rain is plentiful. In June, raise the mowing height and don’t let the lawn dry out too much before starting the summer watering schedule. Should large areas die in the summer, add Stadium Special perennial rye grass, to your favorite blend in fall for a quick recovery.

Turf Disease in Fescue Lawns

Fescue diseases can be a little more predictable and easily forecast by the temperature and humidity when added together (see example) are higher than 150.  Applying granular Fungus Fighter at 21 day intervals from mid-May through mid-August, when conditions are most favorable for disease, should keep you ahead of the game.

Turf Disease in Zoysia Lawns

Large patch disease in zoysia can pop anytime during the growing season when cool wet conditions prevail. It’s very common to see in early spring and late fall as the zoysia is going into or coming out of winter dormancy. Large patch can also appear in shaded areas and wet areas in mid-summer. Large patch can be a real problem for several years in a row and can show up in the same spots in spring and fall. In the fall, circular patches start to discolor and turn bright orange. Look for pinpoints of reddish-brown to black lesions at the base of the leaf. You will need to dig into the thatch layer to see these lesions. If there is a history of large patch, a preventative application of Fungus Fighter in late September to early October is recommended. An application of Fungus Fighter in spring will protect the turf from a fall infection, prevent patches from getting larger and also control disease development in spring.

Managing Your Turf to Reduce Disease

Managing humidity at the ground level is important. Avoid watering the lawn until it needs it.  When you have a choice only water early in the day, so the grass is not wet overnight. Mowing cool season grasses lower in May and early June will be critical in reducing the amount of dew on the grass. Decrease the effect of turf disease by introducing genetic diversity into your lawn each fall by overseeding with improved disease-resistant varieties of Grass Pad grass seed.

What is Resistance Management?

Certain fungal pathogens are known to develop resistance to products with the same mode of action when used repeatedly. Because resistance development cannot be predicted, the use of this product should conform to resistance management strategies established for turf. Such strategies may include rotation with products having different modes of action or limiting the total number of applications per season. For more information on developing a resistance management strategy talk to the turf experts at your nearest Grass Pad location.
