As summer temperatures arrive with warm nights and higher humidity, patches, spots, eyes and slime show up quicker than a chicken on a June bug.  Lawn disease time is just around the corner.

Hot, humid temperatures mean disease and fungus in your yard. Start early, lawn spots are a lot easier to prevent than control.  By applying granular Fungus Fighter now, 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 can stimulate turf disease. Grass Pad’s Fungus Fighters allow a healthy lawn to outgrow many of the diseases that show up. 

Bluegrass Fungus

Bluegrass diseases show up in the form of a slime or dust that wipes off, or even a patch that seems to die overnight.  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.  If fungus shows up apply fast acting liquid fungicide and follow up with granular Fungus Fighter one week later.  If large areas die in the summer, add Stadium Special perennial rye grass, to your blend this fall and do what you can to help the soil.

Fescue Fungus

Fescue diseases can be a little more predictable than bluegrass.  Expect fungus to show up as soon as the temperature and humidity added together reach 150, usually early in June.  Applying granular Fungus Fighter every 21 days through mid-August should keep you ahead of the game.  If fungus patches to appear or every other blade of grass is brown, apply liquid Fungus Fighter, then granular one week later.  Be sure and overseed those areas every fall. Only use the newest varieties of fescue, like Heat Wave or Macho Mix to ensure the most up to date disease resistant varieties. 

Zoysia Large Patch

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 now will protect the turf from a fall infection, prevent patches from gettinglarger and also control disease development in spring.

One-Two Punch

If you are fighting fungus patch now, give it a one-two punch. First, use fast acting liquid Fungus Fighter for immediate control followed by an application of granular Fungus Fighter for a more long lasting control. Get to the Grass Pad, see our grass doctors and get the right “anti-biotic” for your lawn.

General Information:

Uncle’s granular Fungus Fighter provides control of many important diseases in turf including but not limited to Kentucky bluegrass, annual bluegrass, fescue, rye, and zoysia grass.

Fungus Fighter is a broad-spectrum xylem systemic fungicide for the control of certain diseases in turf. Fungus Fighter works by interfering with the respiration in plant-pathogenic fungi, and is a potent inhibitor of spore germination and mycelial growth. The active ingredient moves rapidly into green tissue via transluminal and xylem movement. Roots of plants take up the active ingredient where it is translocated throughout the xylem of plants to provide internal inhibition of fungal growth and protect the plant from new infections. The broad spectrum of activity of Fungus Fighter makes it an excellent choice as the foundation fungicide for turf management programs.

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.
