Details

DIRECTIONS FOR USE

It is a violation of Federal Law to use this product in a manner inconsistent with its labeling. Read entire label before using this product. Use strictly in accordance with label precautionary statement and directions.

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. Keep people and pets out of the area during application. For any requirements specific to your State or Tribe, consult the agency responsible for pesticide regulation.

USE RESTRICTIONS

Do not apply this product by air or through any type of irrigation equipment. Do not use on golf course greens, tees and collars. Do not use on lawns with desirable clovers or legumes or on ornamentals. Not for use on sod farms in Arizona. For use in New York by spot treatment only (spray individual weeds only; adjust the sprayer to coarse spray to minimize wind drift, apply to the center of the weeds and spray to lightly cover). For use-specific restrictions in application rates and number of applications, please see APPLICATION INSTRUCTIONS AND RESTRICTIONS section.

USE TIMING

Apply Quincept to actively growing weeds as a postemergence broadcast or spot spray. Follow-up applications may be required for dense infestations of broadleaf and grassy weeds. Under certain conditions, application of Quincept made to annual grasses at 2 to 4-tiller may not provide complete control.

NEWLY SEEDED AREAS:

The application of Quincept to grass seedlings is not recommended until after the third mowing.

NEWLY SODDED, SPRIGGED, OR PLUGGED AREAS:

The application of Quincept to newly sodded, sprigged, or plugged grasses should be delayed until 3 to 4 weeks after the sodding, sprigging, or plugging operations. Delay applications for 4 weeks after seeding and emergence of Kentucky Bluegrass, Perennial Ryegrass and Fine Fescues.

SEEDING:

Delay applications for 4 weeks after seeding and emergence of turf species listed on this label.

MOWING:

It is recommended to not mow for two days before or two days after application. Clippings for the first three mowings should be left in the application area. Do not use clippings as mulch or compost around flowers, ornamentals, trees, or in vegetable gardens.

IRRIGATION AND RAINFALL:

If soil moisture is not sufficient prior to application, irrigation may improve weed control. For best results, DO NOT water or irrigate for 24 hours after application. If rainfall does not occur in 2 to 7 days after application, irrigation of at least one-half inch is required.

Do not apply this product by air or through any type of irrigation equipment.

MIXING INSTRUCTIONS:

Begin with a clean spray tank. Fill the spray tank with one-half the required amount of clean water. Slowly add Quincept while agitating, then complete filling the tank with water. maintain continuous agitation until spraying is complete. If left standing for extended periods of time, re-agitate to assure uniformity of the spray mixture.

Adding adjuvants may cause slight leaf burn, but turf vigor is not reduced. Delaying applications when relative humidity and temperatures are high may help to avoid potential for leaf burn and turfgrass damage. Low mowing heights may also increase the possibility of turf injury. The addition of chelated iron or sprayable solution nitrogen fertilizer will reduce slight yellowing.

For best results, the addition of methylated seed oil is recommended when it meets all of the following criteria.

  • be non-phytotoxic
  • contain only EPA-exempt ingredients
  • provide good mixing quality in the jar test.
  • be successful in local experience

Including additives when tank mixing with emulsifiable concentrate (EC) products may cause phytotoxicity. Adding oil, wetting agent, or other appropriate surfactant to the spray may be used to increase effectiveness on weeds but doing so may reduce selectivity to turf resulting in turf damage. Clean and rinse spray equipment using soap or detergent and water, and rinse thoroughly before reuse for other sprays.

This product can be mixed with some liquid fertilizers or liquid iron materials. Because liquid fertilizers and liquid iron differ in pH, free ammonia content, density, salt concentration and percentage of water, a compatibility test is recommended prior to mixing in the application equipment. All regulations, either State or Federal, relating to the application of liquid fertilizers or liquid iron and this product must be strictly followed.

Quincept may be tank mixed with EPA-registered preemergent herbicides (if compatible) for extended residual control. It is the pesticide user's responsibility to ensure that all products in the listed mixtures are registered for the intended use. Users must follow the most restrictive directions for use and precautionary statements of each product in the tank mixture.

The following compatibility test should always be performed prior to full-scale tank mixing.

  1. Pour 18 ounces of water into a quart jar.
  2. Add 1 ounce of either the liquid fertilizer or liquid iron to be used.
  3. Add 1 ounce of this product.
  4. Close jar and shake well.
  5. Watch the mixture for several seconds after shaking and check again after 30 minutes.
  6. If the mixture does not show signs of separating, the combination may be used. If the mixture foams excessively, gels, separates or gets very thick, do not combine for field application.
  7. Compatibility may be improved by the use of a compatibility agent. Follow the previously outlined test procedures and add 1/6 ounce of the compatibility agent between steps (the compatibility agent must be added to the fertilizer or iron before adding this product).
  8. If the mixture does not separate, gel, foam or get very thick, it may be used for field application. Mix only the amount to be sprayed. Do not allow to stand overnight.
  9. Sprayer Cleaning: Clean application equipment thoroughly before and after application to prevent cross contamination. Use a strong detergent or approved spray tank cleaner and rinse thoroughly.
