Product Overview

Empero Q-Pak is a selective post-emergent herbicide that provides the convenience of pre-measured packs with the power of tough weed control to takedown purple and yellow nutsedge, kyllinga, and many broadleaf weeds.  The pre-measured packets of Empero require no measuring – simply mix with one gallon of water and you can start tackling nutsedge in residential and commercial lawns, landscaped areas, athletic fields, roadsides, and many non-crop areas.

The water dispersible granule formulation means that this nutsedge killer dissolves quickly and mixes easily in water.  Containing the active ingredient halsulfuron-methyl, Empero Q-Paks can be used on many warm- and cool-season lawns including bermudagrass, centipede grass, Fine and Tall Fescue, Zoysia, St. Augustinegrass and more. 

When treating for nutsedge, kyllinga, and broadleaf weeds, each 13.5 g packet can treat 1,000 sq. ft.  For the best control with nutsdge, spray when the plant reaches the 3 to 8 leaf growth stage. 

For larger treatment areas, Empero is available in a 1.33 oz bottle.

DIRECTIONS FOR USE
For Yellow or Purple Nutsedge, Kyllinga, and Broadleafe Weeds:  In turfgrass, including commercial and residential turfs, established lawns, and ornamental turfgrass, apply Empero Q-Pak for post emergent control of purple or yellow nutsedge, Kyllinga, and broadleaf weeds.  Mix 0.5oz (13.5 grams / 1 pouch) in 1 gallon of water to treat 1,000 sq ft of turfgrass.  Mix or shake solution to ensure ingredients are completely dispersed. Spray the targeted weeds thoroughly and wet the entire leaf surfance of the undesirable plant.  For best results, spray nutsedge after it has reached the 3 to 8 leaf stage of growth.  

For post-emergence control of Horsetail:  Apply 1 oz (27 grams / 2 packs) in 1 gallon of water to treat 1,000 sq. ft after horstail has leafed out.  This rate will control horsetail that is less than 6 inches tall and suppress horsetail that is greater than 6 inches tall. 

See label for full application directions and usage rates, including for treating around woody ornamentals in landscaped areas, fallow ares, fence rows, fuel storage areas, lumberyards, tank farms, right of ways, roadsides, non-crop sites including campgrounds, cemeteries, fairgrounds, public recreation areas, race tracks, residential property, school grounds, sports fields, and tennis courts. 

 

WEED RESISTANCE MANAGEMENT

Empero Q-Pak is a Group 2 herbicide (ALS/AHAS inhibitors). Any weed population may contain or develop plants naturally resistant to Empero Q-Pak and other Group 2 herbicides. Weed species with acquired resistance to Group 2 herbicides may eventually dominate the weed population if Group 2 herbicides are used repeatedly in the same field or in successive years as the primary method of control for targeted species. This may result in partial or total loss of control of those species by Empero Q-Pak or other Group 2 herbicides. Users should scout before and after application.

Suspected herbicide-resistant weeds may be identified by these indicators:

  • Failure to control a weed species normally controlled by the herbicide at the dose applied, especially if control is achieved on adjacent weeds;

  • A spreading patch of non-controlled plants of a particular weed species; and
  • Surviving plants mixed with controlled individuals of the same species.

To delay herbicide resistance:

  • Avoid the consecutive use of Empero Q-Pak or other target sites of action Group 2 herbicides that might have a similar target site of action, on the same weed species.

  • Use tank mixtures or premixes with herbicides from different target site of action Groups as long as the involved products are all registered for the same use, have different sites of action and are both effective at the tank mix or pre-pack rate on the weed(s) of concern (an herbicide mode of action classification by itself may not adequately address specific weeds that are resistant to specific herbicides)
  • Base herbicide use on a comprehensive Integrated Pest Management (IPM) program.
  • Scout fields prior to application to identify the weed species present and their growth state to determine if the intended application will be effective.
  • Scout fields after application to verify that the treatment was effective.
  • Contact your local extension specialist, certified crop advisors and/or manufacturer for herbicide resistance management and/or integrated weed management recommendations for specific crops and resistant weed biotypes.

Report any incidence of non-performance of this product against a particular weed species to your Atticus, LLC retailer, representative or call 984-664-9804. If resistance is suspected, treat weed escapes with an herbicide having a different mechanism of action and/or use non-chemicals means to remove escapes, as practical, with the goal of preventing further seed production.

SPRAY DRIFT

THE APPLICATOR IS RESPONSIBLE FOR AVOIDING OFF-SITE SPRAY DRIFT. BE AWARE OF NEARBY NON-TARGET SITES AND ENVIRONMENTAL CONDITIONS.

IMPORTANCE OF DROPLET SIZE

An effective way to reduce spray drift is to apply large droplets. Use the largest droplets that provide target pest control. While applying larger droplets will reduce spray drift, the potential for drift will be greater if applications are made improperly or under unfavorable environmental conditions. SHIELDED SPRAYERS Shielding the boom or individual nozzles can reduce spray drift. Consider using shielded sprayers. Verify that the shields are not interfering with the uniform deposition of the spray on the target area.

TEMPERATURE AND HUMIDITY

When making applications in hot and dry conditions, use larger droplets to reduce the effects of evaporation.

TEMPERATURE INVERSIONS

Drift potential is high during a temperature inversion. Temperature inversions are characterized by increasing temperature with altitude and are common on nights with limited cloud cover and light to no wind. The presence of an inversion can be indicated by ground fog or by the movement of smoke from a ground source or an aircraft smoke generator. Smoke that layers and moves laterally in a concentrated cloud (under low wind conditions) indicates an inversion, while smoke that moves upward and rapidly dissipates indicates good vertical air mixing. Avoid applications during temperature inversions.

WIND

Drift potential generally increases with wind speed. AVOID APPLICATIONS DURING GUSTY WIND CONDITIONS. Applicators need to be familiar with local wind patterns and terrain that could affect spray drift.

WINDBLOWN SOIL PARTICLES

Empero Q-Pak has the potential to move off-site due to wind erosion. Soils that are subject to wind erosion usually have a high silt and/or fine to very fine sand fractions and low organic matter content. Other factors which can affects the movement of windblown soil include the intensity and direction of prevailing winds, vegetative cover, site slope, rainfall, and drainage patterns. Avoid applying Empero Q-Pak if prevailing local conditions may be expected to result in off-site movement.

APPLICATION EQUIPMENT AND INSTRUCTIONS

Calibrate application equipment prior to application of this product. Application should be uniform and of sufficient volume to avoid streaking or skips. Empero Q-Pak often works with 1 application, but depending on the size and age of the nutsedge a second treatment may be required 6 - 10 weeks after the initial treatment. Herbicide symptoms are likely to show within 2 weeks as a necrotic ring at the base of the plant, even though the leaves and stems remain green and a deep leathery green in color. 

SPRAY DRIFT ADVISORIES

Boom-less Ground Applications:

  • Setting nozzles at the lowest effective height will help to reduce the potential for spray drift.

Handheld Technology Applications:

  • Take precautions to minimize spray drift.

It is a violation of Federal law to use this product in a manner inconsistent with its labeling. Do not apply this product in a way that will contact workers or other persons, either directly or through drift. Only protected handlers may be in the area during application. For any requirements specific to your State or Tribe, consult the agency responsible for pesticide regulation.

    Look out, nutsedge!

    By Dave on 06/02/2023

    It seems to be killing the nutsedge I have been fighting in my flower garden. Grass turns yellow, over 10-14 days. The jury is still out on wether it will kill the remaining stringer pods,under the soil. The above ground plants are killed quicker with 30% vinegar, but if the underground pods go away, it will get 6 stars!

    Nut sedge

    By Tommy on 09/29/2023

    Followed directions. Barely phased the NS. Since I bought a two pack I will reduce water 2/3rds of a gallon. Hopefully that will nip it in the bud!

Q
When is the best time to apply Empero Q-Pak Herbicide? In spring, before new growth slows or in the fall after it dies?
A

Empero Q-Pak Herbicide is a post emergent to treat actively growing weeds. Typically, post emergents are best applied when temperatures are between 65 and 85 degrees. For the most accurate timing to treat specific weeds in your area, we recommend contacting the Master Gardener with the County Cooperative Extension Office for their recommendation.
