Zoysia grass in a yard

Where to Inspect

Zoysia grass grows primarily in the southern portion of the United States in areas with full sun and warmer climates. Sites with soil temperatures between 80 to 95 degrees Fahrenheit and partial shade can expect this plant to grow. 

Common sites for Zoysia grass to grow in are lawns, sports turf, and golf courses. 

What to Look For

When inspecting lawns, be sure to look out for discolored patches of turf that don’t match your desired turf cover. When the weather cools, look out for patches of grass that may have lost its color at a different rate from the native turf.


After identifying Zoysia grass and inspecting where it is most active in your lawn, you can begin to treat your area. Be sure to wear the appropriate personal protective equipment (PPE) before handling or applying any type of product.

Zoysia Grass grows in the summer, so you are going to want to spray a herbicide in the late summer when it is actively growing.

We recommend using a non-selective herbicide like Eraser 41%. This is a Glyphosate based herbicide that kills all plants that come in contact with it, so be careful when applying it so you don't get it on desired plants.

Step 1 - Measure and Mix Eraser 41%

Mixing Glyphosate in Sprayer

Eraser 41% Herbicide is a post-emergent herbicide designed to control a wide variety of grassy and broadleaf weeds, including Zoysia Grass.

This is a non-selective, glyphosate product with no soil activity. This means that it will control and kill vegetation that it comes into contact with, so it is recommended to use this for spot treatments.

Determine how much Eraser 41% Glyphosate to use by measuring the square footage of the treatment area. To do this, measure the length and width of the treatment area in feet then multiply them together (length X width = square footage). 

To get rid of Zoysia grass, perform a spot treatment with Eraser 41% Glyphosate. 

Apply 2 1/2 oz. (5 Tbs). of Eraser 41% Glyphosate per gallon of water to treat an area approximately 300 sq. ft. 

You will need a handheld pump sprayer to mix and apply this product. To avoid cross-contamination with other herbicides, we recommend marking this sprayer specifically for non-selective herbicides. 

A blue marking dye such as Vision Pro Max Indicator Dye will help to keep track of where you have sprayed. Vision Pro Max will dye your solution blue so you can see exactly where you have applied your herbicide.

Simply add 0.10 oz. of Vision Pro Max Indicator Dye per 1 gallon of solution. 

To mix, fill the sprayer with half the amount of water then pour in the proper amount of Eraser 41% Glyphosate. Next, pour in the remaining half of water. Add the Vision Pro Max Indicator Dye and agitate the spray tank until well-mixed.

Step 2: Apply Eraser 41% to the Zoysia Grass

Spot treating eraser

Once mixed, spot treat your lawn where the Zoysia Grass is concentrated.

Since Eraser 41% Glyphosate is a non-selective herbicide, it is recommended to use some sort of shield such as a cardboard box. This will help to block the spray from contacting your wanted vegetation. 

Use a fan or cone spray pattern to ensure the leaves are fully coated, and spray the weed to the point of wet but not runoff.

Best to make applications when temperatures are above 60 degrees Fahrenheit on a warm, sunny day. Zoysia grass control will be enhanced when making applications during these conditions.

Most treated weeds usually show initial symptoms in 2-4 days and complete kill in 1-2 weeks. Hard-to-control weeds may require a second application if not completely dead in 4 weeks.


Prevention is the best cure when it comes Zoysia grass as it can be very stubborn. Not every homeowner has the time or patience to deal with Zoysia grass, which is exactly why it is imperative that every homeowner takes certain steps to prevent it from returning after getting rid of it:

Mowing grass

  • Keep your grass trimmed and well-maintained with regular mowing at heights of 3 inches or more to encourage better root growth so your desired grass prevents Zoysia grass from thriving.
  • Apply fertilizer at the best times (ideally in the fall) for your lawn to keep your desired turf thick and lush so Zoysia Grass doesn't have an opportunity to take over.
  • Water the grass deeply yet infrequently. We recommend once a week at a rate of 1 inches of water early in the morning so it has enough absorb into the soil. 
  • Rake and dethatch your lawn to allow for better aeration of your lawn as well as address issues like soil compaction and poor drainage.
