INSTIGATE herbicide must be used only in accordance with instructions on this label or in supplemental DuPont publications. DuPont will not be responsible for losses or damage resulting from use of this product in any manner not specifically specified by DuPont.
INSTIGATE herbicide is a water dispersible blend containing 45.8% active ingredients by weight.
INSTIGATE is a selective herbicide for burndown and residual control of certain annual grass and broadleaf weeds.
INSTIGATE can be tank mixed with a variety of corn herbicides to improve burndown and residual control.
INSTIGATE is a blend of rimsulfuron and mesotrione, two active ingredients that have different mode-of-action on susceptible weeds.
When surface applied, rainfall or sprinkler irrigation is needed to move INSTIGATE into the soil root zone. INSTIGATE is absorbed through the roots, rapidly inhibiting plant growth. Susceptible weeds will generally not emerge from preemergence application. 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 but stunted and noncompetitive. Dry conditions following application may reduce the preemergence activity of INSTIGATE. If an activating rain (0.5 inches) is not received within 5-7 days after preemergence application, where appropriate, rotary hoeing is suggested to activate the herbicide. When applied to emerged vegetation, susceptible weeds take up the herbicide through the treated foliage and cease growth soon after application. Complete death of susceptible weeds may take up to 2 weeks. On all field corn hybrids, DuPont INSTIGATE can be used in a planned sequential application herbicide program such as INSTIGATE followed by an in-crop application of DuPont ACCENT Q, DuPont REALM Q, DuPont RESOLVE Q, DuPont REVULIN Q or DuPont STEADFAST Q with appropriate tank mix partners not exceeding 1.0 ounce active ingredient rimsulfuron or 3.85 ounces active ingredient of mesotrione during the crop year. For glyphosate-tolerant field corn hybrids, INSTIGATE can be followed by an in-crop application of a glyphosate product, such as DuPont ABUNDIT brands, with appropriate tank mix partners and adjuvant products. Refer to the label of the respective sequential partner for specific use directions.

Do not make more than 1 application of INSTIGATE per year.
Do not apply to corn grown for seed, popcorn, ornamental (Indian) corn, or sweet corn.
Do not apply another solo HPPD inhibitor postemergence herbicide such as “Callisto”, “Impact” or “Laudis” to ground that has been treated with INSTIGATE in the same season.
Do not apply preemergence to coarse-textured soils (sand, loamy sand or sandy loam) with less than 1% organic matter.
Do not apply more than 3.85 ounces active ingredient of mesotrione in a year. This includes combinations of preemergence applications of INSTIGATE, as well as mesotrione from application(s) of products such as REALM Q or REVULIN Q. Do not make the second application of a mesotrione containing product within 14 days of the first application.
Do not apply more than a total of 1.0 ounce active ingredient rimsulfuron during the crop year. This includes combinations of preemergence applications of INSTIGATE, as well as rimsulfuron from application(s) of products such as DuPont BASIS Blend, DuPont LEADOFF, DuPont PREQUEL, DuPont RESOLVE Q, REALM Q or DuPont STEADFAST Q.
Do not tank mix INSTIGATE with “Basagran” or severe crop injury may occur.
Do not tank mix INSTIGATE 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 seven days before or 3 days after the application of INSTIGATE.
Do not apply the organophosphate insecticide, terbufos ("Counter") within 45 days of a preemergence or preplant application of INSTIGATE since crop injury may result.
Do not apply INSTIGATE within 45 days of crop emergence where the organophosphate insecticide, terbufos ("Counter") was applied as a treatment since crop injury may occur.
Do not irrigate INSTIGATE herbicide into coarse soils at planting time when soils are saturated.
Do not apply this product through any type of irrigation system.
Do not use aerial application to apply INSTIGATE unless specified otherwise under the specific crop section on the label.
Do not apply with suspension fertilizers as the carrier, unless specifically addressed under one of the tank mix sections of this label or other product labels containing mesotrione, or injury may occur.
Do not graze, feed forage, grain or fodder (stover) from treated areas to livestock within 45 days of INSTIGATE application.
Injury or loss of desirable trees or vegetation may result from failure to observe the following:
- Do not apply INSTIGATE 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 contact with their roots.
- Do not use on lawns, walks, driveways, tennis courts, or similar areas.
- Do not contaminate any body of water.

Allow at least 4 weeks between preemergence application of INSTIGATE and postemergence applications of unsafened rimsulfuron-containing herbicides.
INSTIGATE herbicide may interact with certain insecticides previously applied to the crop. Crop response varies with field corn type, insecticide used, insecticide application method, and soil type. Preplant/Preemergence applications of INSTIGATE to corn where an application of "Counter", “Lorsban", or “Thimet” is planned may cause unacceptable crop injury, especially on soils of less than 4% organic matter. INSTIGATE may be applied to corn previously treated with Fortress, SmartChoice, Aztec, or Force insecticides, or other non-organophosphate soil insecticides regardless of soil type.
INSTIGATE may be applied with pyrethroid type insecticides such as “Asana” or “Warrior” or with diamide type insecticides such as DuPont PREVATHON. When weeds are stressed due to drought, heat, lack of fertility, flooding, or prolonged cool temperatures, control can be reduced or delayed since the weeds are not actively growing. Weed escapes or regrowth may occur when application is made under prolonged stress conditions. Optimum weed control will be obtained if an application of DuPont INSTIGATE is made following label direction when weeds are actively growing. Crop injury may occur following an application of INSTIGATE 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.
