General Information


Product Information

DuPont RESOLVE SG herbicide must be used only in accordance with instructions on the 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.

RESOLVE SG herbicide is a water soluble granule containing 25% active ingredient by weight. RESOLVE SG is a selective herbicide for burndown and residual control of certain annual grass and broadleaf weeds when applied fallow or preemergence to field corn. RESOLVE SG may be applied in tank mix combinations with other corn herbicides for improved burndown and residual control.

RESOLVE SG 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 RESOLVE SG into the soil. Susceptible weeds will generally not emerge from a 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, stunted and noncompetitive.

The herbicidal action of RESOLVE SG may be less effective on weeds stressed from adverse environmental conditions (such as extreme temperatures or moisture), abnormal soil conditions, or cultural practices.

RESOLVE SG treatments are most effective in controlling weeds when adequate rainfall is received 5 -7 days after application. If cultivation is necessary because of soil crusting, soil compaction or weed germination before rain occurs, use shallow tillage such as rotary hoe to lightly incorporate RESOLVE SG and make certain corn seeds are below the tilled area.

RESOLVE SG is best used in a planned sequential application herbicide program, to be followed by an in-crop application of RESOLVE Q, DuPont STEADFAST Q, and/or other post applied corn herbicides. Refer to the label of the respective sequential partner for specific use directions.

Do not apply to field corn grown for seed, to popcorn or to sweet corn.

Do not apply more than a total of 2.0 oz RESOLVE SG (or 0.5 oz active ingredient rimsulfuron) during the crop year. This includes combinations of preemergence applications of RESOLVE SG, as well as rimsulfuron from application(s) of products such as DuPont BASIS, DuPont PREQUEL, RESOLVE Q, and STEADFAST Q.

Limit preemergence rates of RESOLVE SG to a maximum of 1.25 oz product if following with postemergence applications of the rimsulfuron containing products noted above.

Do not apply preemergence to coarse-textured soils (sand, loamy sand or sandy loam) with less than 1% organic matter.

Apply RESOLVE SG to field corn hybrids with a relative maturity (RM) of 77 days or more, including “food grade” (yellow dent, hard endosperm), waxy and High-Oil corn.

Not all field corn hybrids of less than 77 days RM, not all white corn hybrids nor Hi-Lysine hybrids have been tested for crop safety, nor does DuPont have access to all seed company data. Consequently, injury arising from the use of RESOLVE SG on these types of corn is the responsibility of the user. Consult with your seed supplier before applying RESOLVE SG to any of these corn types. Seed company publications indicate “Warning”, “Crop Response Warning”, or “Sensitive” notations for the use of some ALS herbicides on corn hybrids of 77 CRM or higher. As noted in the seed company publications, DuPont sulfonylurea herbicides such as RESOLVE SG should be used with caution on these hybrids. Consult with your local DuPont representative or the DuPont Label Web Site ( for any additional supplemental labeling information relative to potential corn hybrid sensitivity to RESOLVE SG.

Ground Application

Use a minimum of 15 gallons of water per acre (GPA) to ensure thorough coverage of the weeds and the best performance. Use a minimum of 10 GPA for light, scattered stands of weeds. Select nozzles and pressure that deliver MEDIUM spray droplets, as indicated, for example, by ASAE Standard S572. Nozzles that deliver COARSE spray droplets may be used to reduce drift, provided spray volume is increased to maintain coverage on small weeds.

For optimal product performance and minimal spray drift, adjust the spray boom to the lowest possible spray height recommended in manufacturers’ specifications. Ensure that equipment is set up to avoid applying an excessive rate directly over the rows and into the corn plant whorl. Overlaps or starting, stopping, slowing, and turning while spraying may result in crop injury.

Aerial Application

Use MEDIUM or COARSE nozzles that will provide optimum spray distribution and maximum coverage at a minimum of 5 GPA.

Do not apply when winds are greater than 10 mph, or when conditions favor poor coverage and/or off-target spray movement. If applying at wind speeds less than 3 mph, the applicator must determine if: a) conditions of temperature inversion exist, or b) stable atmospheric conditions exist at or below nozzle height. Do not make applications into areas of temperature inversions or stable atmospheric conditions.

Aerial application is not permitted in the State of New York.


This product may be used as part of an Integrated Pest Management (IPM) program that can include biological, cultural, and genetic practices aimed at preventing economic pest damage. IPM principles and practices include field scouting or other detection methods, correct target pest identification, population monitoring, and treating when target pest populations reach locally determined action thresholds. Consult your state cooperative extension service, professional consultants or other qualified authorities to determine appropriate action treatment threshold levels for treating specific pest/crop systems in your area.


When herbicides that affect the same biological site of action are used repeatedly over several years to control the same weed species in the same field, naturally-occurring resistant biotypes may survive a correctly applied herbicide treatment, propagate, and become dominant in that field.

Adequate control of these resistant weed biotypes cannot be expected. If weed control is unsatisfactory, it may be necessary to retreat the problem area using a product affecting a different site of action.

To better manage herbicide resistance through delaying the proliferation and possible dominance of herbicide resistant weed biotypes, it may be necessary to change cultural practices within and between crop seasons such as using a combination of tillage, retreatment, tank-mix partners and/or sequential herbicide applications that have a different site of action. Weed escapes that are allowed to go to seed will promote the spread of resistant biotypes.

It is advisable to keep accurate records of pesticides applied to individual fields to help obtain information on the spread and dispersal of resistant biotypes. Consult your agricultural dealer, consultant, applicator, and/or appropriate state agricultural extension service representative for specific alternative cultural practices or herbicide recommendations available in your area.


- DuPont RESOLVE SG 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.

- RESOLVE SG may be applied to corn previously treated with Fortress, SmartChoice, Aztec, or Force insecticides, or nonorganophosphate soil insecticides regardless of soil type.

- Allow at least 60 days between a preemergence or preplant application of RESOLVE SG and application of organophosphate insecticide since crop injury may result.

- Allow at least 4 weeks between preemergence application of RESOLVE SG and postemergence applications of unsafened rimsulfuron-containing herbicides.
