How To Use Sedgemaster Herbicide

Sedgemaster Herbicide, when used as directed on the label, is harmless to humans and animals. When using this product, it is imperative that you always safeguard yourself by donning the necessary protective gear.

If you want your lawn to look its best after a treatment, wait at least two days before and after mowing. This gives the treatment adequate time to reach the tall sedges where it can do its work.

Grass that is already under stress at the time of treatment is more likely to show signs of discoloration. Possible lethal effects on plants that come into contact.


What Is the Sedgemaster Herbicide?

This granule is water-dispensible and easy to use, so it can be targeted at specific weeds or broadcast across vast regions (in acres).

After application, the weeds are immediately killed off because of the 75% halosulfuron-methyl concentration in the formula.

Sedgemaster swiftly takes action on selected weeds, slowing their growth and allowing the crop to catch up with and surpass their development.

In the aftermath of development being halted, the leaves and developing tip begin to turn brown and eventually die.

And while Sedgemaster Herbicide’s primary purpose is to get rid of nutsedge, it also works well on other broadleaf weeds in both warm- and cool-season turf and in landscape settings.

In order to effectively control weeds, uniform, and thorough spraying is required.

See the product label for a comprehensive list of compatible tank mix partners, but in general, Sedgemaster can be combined with any other pesticide product that is registered for the same crop and application procedures.

How To Use Sedgemaster Herbicide

  • Find out how big of an area needs to be treated. You may calculate the square footage by measuring the length and width and multiplying the results.
    You can calculate the acreage of a property by dividing its square footage by 43,560. Depending on the type of weed and size of the treatment area, you’ll need anywhere from 10 to 100 gallons of water per ounce of product.
    Treatment of 1,000 square feet requires a mixture of 0.03 to 0.06 ounces of product with 1 to 2 gallons of water.
  • The sprayer should be half full of water before adding the calculated amount of Sedgemaster. To achieve a uniform mixture, fill your sprayer to the top with water and give it a good shake.
  • Use either a broad spray or targeted applications to cover your area. Use the herbicide evenly, spraying the weeds until they are soaked but not running off.
    Nobody should enter the treated area until it has completely dried. For weeds that have already taken root, a second treatment may be required.

With SedgeMaster’s rapid action, the crop can quickly outpace the growth of the weeds it is intended to control. As the weeds’ growth is stifled, their leaves and growing point turn brown and eventually die.

Depending on the weed’s size, species, and environmental conditions, total eradication can happen in as little as 7 days.

If Group 2 herbicides are used extensively in the same field or in successive years as the major method of control for target species, weeds that have gained resistance to those herbicides may eventually dominate the weed population.

Weeds can be eradicated in as little as 7 days or as long as 14 days, depending on their growth and development stage. Use Sedgemaster when weeds are just starting to grow, before they have a chance to become established, for the best results.

Use when there is no chance of precipitation for at least 4 hours and the wind speed is low enough to prevent drift.
