Product Overview

DuPont Realm Q Herbicide is a granular formula provides powerful post-emergent control and suppression of broadleaf weeds and certain annual grasses on corns, cotton, peas, peanuts, rice, soybeans, and other listed crops. This selective herbicide contains a combination of two active ingredients Rimsulfuron and Mesotrione which provides multiple modes of action for superior control and protection. It is absorbed through the roots and foliage tissue to quickly prevent the growth of susceptible weeds. It can also be combined with other herbicides to help improve residual activity and burndown of troublesome weeds. Product rainfast in as little as 4 hours. Effective against amaranth, barnyardgrass, bluegrass, buckwheat, buffalobur, carpetweed, chickweed, cocklebur, crabgrass, dandelion, foxtail, Jimsonweed, Johnsongrass, knotweed, kochia, lambsquarters, pigweed, ryegrass, thistle, witchgrass, woolly cupgrass, and more.

  • Do not apply to field corn grown for seed, to popcorn or to sweet corn.
  • Do not apply more than 4.0 oz of REALM Q per acre per year.
  • Do not apply more than 1.0 oz active ingredient rimsulfuron in a year. This includes postemergence applications of REALM Q, as well as rimsulfuron from applications of products such as ALLUVEX, BASIS Blend, INSTIGATE, LEADOFF, PREQUEL, RESOLVE Q, RESOLVE SG and STEADFAST Q.
  • Do not apply more than 3.85 ounces active ingredient of mesotrione in a year. This includes postemergence applications of REALM Q, as well as mesotrione from application(s) of products such as INSTIGATE or REVULIN Q. Do not make the second application of a mesotrione containing product within 14 days of the first application.
  • Do not tank mix REALM Q with “Basagran” or severe crop injury may occur.
  • Do not tank mix REALM Q with foliar-applied organophosphate or carbamate insecticides such as chlorpyrafos (“Lorsban”), malathion, parathion, etc, as severe crop injury may occur. To avoid crop injury or antagonism, apply these products at least 7 days before or 7 days after the application of REALM Q.
  • Do not apply REALM Q within 45 days of crop emergence where the organophosphate insecticide, terbufos ("Counter") was applied since crop injury may occur. Applications made to corn previously treated with chlorpyrifos or other similar organophosphate insecticides may result in unacceptable crop injury. Any crop injury or yield loss resulting from these applications are the responsibility of the grower.
  • Do not apply REALM Q to corn that exhibits herbicide injury from previous applications made to the current or preceding crop.
  • Do not use liquid nitrogen fertilizer as the total carrier solution for postemergence applications.
  • Injury or loss of desirable trees or vegetation may result from failure to observe the following:
    • Do not apply REALM Q or drain or flush application equipment on or near desirable trees or other plants, or on areas where their roots may extend, or in locations where the chemical may be washed or moved into contract with their roots.
    • Do not use on lawns, walks, driveways, tennis courts, or similar areas.
    • Do not contaminate any body of water.
  • Do not graze, feed forage, grain or fodder (stover) from treated areas to livestock within 45 days of REALM Q application.
  • Do not harvest grain within 70 days or harvest forage or stover within 45 days of REALM Q application.
  • Do not use aerial application to apply REALM Q unless specified otherwise under the specific crop section on the label.
  • Do not apply this product through any type of irrigation system.
  • This product contains 0.0375 pound of the safener isoxadifen-ethyl per pound of product. Applying the maximum application rate of REALM Q at 4 ounces per acre will deliver 0.01 pound of isoxadifen-ethyl per acre. When tank mixing for applications to field corn, do not apply more than a total of 0.17 pound of isoxadifen-ethyl per acre per year.


  • REALM Q may interact with certain insecticides previously applied to the crop. Crop response varies with field corn type, insecticide used, insecticide application methods, and soil type.
  • REALM Q may be applied to corn previously treated with Fortress, SmartChoice, Aztec, or Force insecticides, or other non-organophosphate soil insecticides regardless of soil type.
  • REALM Q may be applied with pyrethroid type insecticides such as “Asana” or “Warrior” or with diamide type insecticides such as DuPont PREVATHON.
  • Crop injury may occur following an application of REALM Q if there is a prolonged period of cold weather and/or in conjunction with wet soils.
  • Prevent drift or spray onto desirable plants.
  • Thoroughly clean application equipment immediately after use (See Sprayer Cleanup section on the label).


Field Corn Grown for Grain or Silage - Postemergence


Apply REALM Q at 4.0 ounces per acre as a postemergence broadcast application. Consult DuPont technical bulletins, fact sheets or supplemental labeling for additional application rate information.

Timing to Crop

REALM Q may be broadcast to corn up to 20 inches tall or that is exhibiting up to and including 6 leaf collars (V6), whichever is more restrictive.

While REALM Q has a wide application window, research has shown best results are obtained when applications are made early postemergence (row n’ go) when corn and weeds are small. Target post applications to corn generally less than 12” tall for best overall performance.

Applications of REALM Q made after weed emergence will provide contact control of labeled weeds as well as residual control of later emerging weeds.

Timing to Emerged Weeds

Apply REALM Q when grasses and broadleaf weeds are young and actively growing, but before they exceed sizes listed on this label. Applications made to weed sizes greater than those listed on this product label may result in incomplete control.

Grass and broadleaf weed competition due to incomplete control may reduce corn yields.

On glyphosate tolerant corn, glyphosate such as ABUNDIT Extra may be applied with REALM Q after weeds emerge but before they reach the maximum size listed on the glyphosate herbicide label.

On "Liberty Link" corn, glufosinate may be applied with REALM Q after weeds emerge but before they reach the maximum size listed on the glufosinate herbicide label.

REALM Q is rainfast in 4 hours.

Sequential Application - Pre

REALM Q may be used as a sequential application in a planned postemergence weed control program in corn following a preemergence herbicide.

Apply preemergence herbicide products such as DuPont ALLUVEX, DuPont BASIS Blend, DuPont BREAKFREE, BREAKFREE NXT or DuPont CINCH brands, DuPont INSTIGATE, DuPont LEADOFF, DuPont PREQUEL, DuPont RESOLVE Q herbicides. Refer to the preemergence herbicide label for use restrictions, application information, rotational crop guidelines, and cautionary statements prior to applying REALM Q.

Do not apply DuPont REALM Q to corn that exhibits herbicide injury from previous applications made to the current or preceding crop.
