PRODUCT INFORMATION
REVULIN Q is a selective herbicide for burndown and residual control of certain annual grass and broadleaf weeds when applied postemergence to field corn grown for grain, silage or seed, yellow popcorn or sweet corn. REVULIN Q can be tank mixed with a variety of herbicides to improve burndown and residual control. REVULIN Q may also be applied with pyrethroid type insecticides such as "Asana" or “Warrior” or with diamide type insecticides such as DuPont PREVATHON Insect Control. REVULIN Q is absorbed through the roots and leaf tissue of plants, rapidly inhibiting the growth of susceptible weeds. Rainfall or sprinkler irrigation is needed to move REVULIN Q into the soil. Susceptible weeds will generally not emerge from a postemerge application with activating rainfall or sprinkler irrigation (>0.5 inch). In some cases, susceptible weeds may germinate and emerge a few days after application, but growth then ceases and leaves become chlorotic three to five days after emergence. Death of leaf tissue and growing point will follow in some species, while others will remain green, stunted and noncompetitive.
DuPont REVULIN Q is best used as part of a sequential application herbicide program, following a preplant or preemerge application of DuPont ALLUVEX, DuPont BASIS Blend, DuPont BREAKFREE or DuPont CINCH brands, DuPont INSTIGATE, DuPont LEADOFF, DuPont PREQUEL, DuPont RESOLVE Q herbicides and/or other pre-applied corn herbicides. Refer to the label of the respective corn herbicide partner for specific use directions.
For postemergence applications of REVULIN Q, if activating rainfall or sprinkler irrigation (>0.5 inch) is not received within 5 to 7 days after application, follow with a cultivation or with a sequential application of DuPont ACCENT Qherbicide or glyphosate such as DuPont ABUNDIT Edge as needed. Degree of control and duration of effect depend on: rate used, weed spectrum, growing conditions at and following time of treatment, soil pH, soil texture, organic matter, moisture and precipitation.

RESTRICTIONS
Do not apply more than 4.0 oz of REVULIN Q per acre per year unless instructed to do so by DuPont Technical Bulletins, or Supplemental Labeling. Make only one application of REVULIN Q per year. Do not apply more than 3.85 ounces active ingredient of mesotrione in a year. This includes postemergence applications of REVULIN Q, as well as mesotrione from application(s) of products such as DuPont INSTIGATE. Do not apply more than 1.0 ounce active ingredient of nicosulfuron in a year. This includes postemergence applications of REVULIN Q, as well as nicosulfuron from application(s) of products such as ACCENT Q or DuPont STEADFAST Q.
Do not tank mix REVULIN Q with “Basagran” or severe crop injury may occur.
Do not tank mix REVULIN Q with foliar-applied organophosphate 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 seven days before or 3 days after the application of REVULIN Q.
Do not apply REVULIN 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 make a late application of REVULIN Q to field corn grown for grain or silage, that is taller than 30 inches or that exhibits 8 or more collars (V8), whichever is more restrictive.
Do not apply to yellow popcorn or seed corn that is taller than 20 inches or that exhibits more than 5 leaf-collars (V5), whichever is more restrictive.
Do not apply REVULIN Q to sweet corn taller than 18 inches or which exhibits 6 or more leaf collars (V6).
Do not apply REVULIN Q to any white popcorn inbred, or white popcorn hybrid or ornamental (Indian) corn.
Do not include nitrogen based adjuvant, UAN, when making postemergence applications of REVULIN® Q to yellow popcorn or sweet corn.
Do not apply REVULIN 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 REVULIN 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 or feed forage, grain or fodder (stove) from treated areas to livestock within 45 days after a REVULIN® Q application.
Do not harvest forage or stover within 45 days after a REVULIN Q application.
Do not harvest grain within 70 days after a REVULIN Q application.
Do not use aerial applications to apply REVULIN 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 0.036 pound of the safener isoxadifen-ethyl per pound of product. Applying the maximum application rate of REVULIN 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 crop growing season.
Applications with wind speeds greater than 10 mph are prohibited.
Applications into temperature inversions are prohibited. Do not apply where/when conditions could favor runoff.
