How To Use Katana Herbicide

Katana Herbicide is a selective herbicide, however, it is still best used for spot treatment. Take care that the product doesn’t accidentally drift onto any plants you intend to keep safe.

This pesticide works slowly but surely. If there is still no sign of death after 2–6 weeks, more applications may be necessary.

When used as directed, Katana Herbicide poses no health risks. Use protective equipment (PPE) for your own safety before using this product (long-sleeved clothing, gloves, face mask, and goggles).

If used as directed, the product is completely secure for use around both children and pets. Kids and pets should stay out of treated areas until they are dry, and they should not be there when the treatment is being done.

PBI Gordon’s Katana Herbicide is a selective, post-emergent herbicide that effectively gets rid of a wide variety of broadleaf and grassy weeds in warm-season turf, including Poa annua, ryegrass, tall fescue, and more than sixty others on the EPA’s official list.

Flazasulfuron, the active ingredient, is taken up by plants at modest rates through their leaves and roots and provides effective post-emergence and some preemergence action.

You need a minimal amount of this product to see significant results from the 5 oz jar.

How To Use Katana Herbicide

  • Get the total square footage by multiplying the length and width measurements by the same number of feet.
    Katana Herbicide is often applied at a rate of 0.034 to 0.068 oz per 1,000 square feet or 1.5 to 3 oz per acre.
    Costs will change based on the type of unwanted vegetation you need to be eradicated. Thus, if you want to get rid of Purple Nutsedge, you would use 0.68 oz per 1,000 square feet in a gallon of water.
    Katana requires 2.04 ounces per 3,000 square feet when diluted with 3 gallons of water.
  • It is recommended that you fill your sprayer up to the halfway point with water. Fill the container halfway with water, then add the Katana Herbicide concentration that you determined earlier. Put the top back on the sprayer and shake it up until the solution is uniform.
  • Depending on how bad your grassy weed problem is, either uses a broad spray or spot treatment, but in either case, make sure to achieve good coverage by using a fan spray.
    A second application should be made in three to four weeks if the problem persists to ensure complete weed control throughout the growing season.

Reapply the herbicide in three to four weeks if the weeds persist. (For instructions on how much to use, read the label).
