Product Overview

Charger Basic Herbicide is a powerful formula that provides long-lasting and broad-spectrum control of annual grasses, broadleaf weeds, and sedges in corn, cotton, soybeans and a wide variety of crops. It contains the highly active ingredient s-metolachlor which is effective against nuisance weeds such as barnyardgrass, bristly foxtail, crabgrass, fall panicum, foxtail millet, giant foxtail, goosegrass, red rice, signalgrass, yellow foxtail, yellow nutsedge, carpetweed, galinsoga, pigweed, tropical spiderwort, and more. It works excellently as a seedling shoot inhibitor, plus it offers a versatile application option to let you meet production requirements accordingly. This liquid formulation may be applied preemergence, early preplant, preplant incorporated, and post-emergence in some crops. Product can be applied alone but can be combined with other preemergent herbicides for a broader spectrum of control and long-lasting protection against weeds. Available in a 2.5-gal jug.

Note: Do not use in nurseries, turf, or landscape plantings.

Do not apply under conditions which favor runoff or wind erosion of soil containing this product to nontarget areas.

To prevent off-site movement due to runoff or wind erosion:

  • Avoid treating powdery dry or light sand soils when conditions are favorable for wind erosion. Under these conditions, the soil surface should first be settled by rainfall or irrigation.
  • Do not apply to impervious substrates, such as paved or highly compacted surfaces.
  • Do not use tailwater from the first flood or furrow irrigation of treated fields to treat nontarget crops, unless at least 1/2 inch of rainfall has occurred between application and the first irrigation.


Application Timing:

CHARGER BASIC alone or in some tank mixtures with other labeled herbicides may be applied for weed control in certain crops at various times. Refer to the given crop section of the label to determine if application timings listed below are recommended.

  • Preplant Surface-Applied: For minimum-tillage or no-tillage systems only, CHARGER BASIC alone and some CHARGER BASIC tank mixtures may be applied up to 45 days before planting certain crops. Use only split applications for treatments made 30-45 days before planting, with 2/3 the recommended broadcast rate for the crop and soil texture applied initially and the remaining 1/3 at planting. Treatments less than 30 days before planting may be made either as a split or a single application. Refer to individual crop to determine if early preplant surface application is recommended. If weeds are present at the time of treatment, apply in a tank mixture combination with a contact herbicide (for example, Gramoxone® MAX or Roundup). Observe directions for use, precautions, and restrictions on the label of the contact herbicide. To the extent possible, do not move treated soil out of the row or move untreated soil to the surface during planting, or weed control will be diminished.
  • Preplant Incorporated: Apply CHARGER BASIC to the soil and incorporate into the top 2 inches of soil within 14 days before planting, using a finishing disk, harrow, rolling cultivator, or similar implement capable of providing uniform 2-inch incorporation. Use a preplant incorporated application if furrow irrigation is used or when a period of dry weather after application is expected. If crop will be planted on beds, apply and incorporate CHARGER BASIC after bed formation, unless specified otherwise.
  • Preemergence: Apply CHARGER BASIC during planting (behind the planter) or after planting, but before weeds or crops emerge.
  • Postemergence: CHARGER BASIC may be applied postemergence to corn, up to 40 inches tall. CHARGER BASIC will not provide postemergence weed control so it must be applied to a weed-free soil surface or in combination with products that provide postemergence control of weed species present at the time of application. Use only where allowed in crop specific directions for use.

Special Application Procedures:

  • CA Only (Corn, Safflowers, Pod Crops): Preplant Incorporated: Broadcast CHARGER BASIC alone or with tank mix partners listed on this label to the soil and thoroughly incorporate with a disk or similar implement set to till 4-6 inches deep. For more thorough incorporation, till the soil in 2 different directions (cross-till). Crops may be planted on flat surface or on beds. Caution should be used when forming the beds that only soil from the CHARGER BASIC treated zone is used (i.e., untreated soil should not be brought to soil surface). If the application is made to preformed beds, incorporate CHARGER BASIC with a tillage implement set to till 2-4 inches deep. Care should be taken during tilling to keep the tilled (CHARGER BASIC treated) soil on the beds. Preemergence: Apply CHARGER BASIC after planting. Water with sprinkler or flood irrigation within 7-10 days.
  • Fall Application (Only in IA, MN, ND, SD, WI, and portions of NE and IL - See specific instructions in the Corn, Soybeans, and Pod Crops sections of this label for timing of application and other information): Do not apply to frozen ground. Use on medium and fine soils with greater than 2.5% organic matter that will be planted to corn or soybeans the next spring. Ground may be tilled before or after application. Do not exceed a 2 to 3-inch incorporation depth if tilled after treatment. Note: If a spring application is made, the total rate of the fall plus spring applications must not exceed the maximum total rate for the specific crop, or illegal residues may result.

Ground Application: Apply CHARGER BASIC alone or in tank mixtures by ground equipment in a minimum of 10 gals. of spray mixture per acre, unless otherwise specified.

Use sprayers that provide accurate and uniform application. For CHARGER BASIC tank mixtures with wettable powder or dry flowable formulations, screens and strainers should be no finer than 50-mesh. Rinse sprayer thoroughly with clean water immediately after use.


Grasses: Barnyardgrass (watergrass), bristly foxtail, crabgrass, crowfootgrass, fall panicum, foxtail millet, giant foxtail, goosegrass, green foxtail, prairie cupgrass, red rice, robust foxtails (purple,white), signalgrass (Brachiaria), southwestern cupgrass, wild proso millet*, witchgrass, woolly cupgrass*, yellow foxtail.

Sedges: Yellow nutsedge

Broadleaf weeds: Carpetweed, common waterhemp, Florida pusley, galinsoga, pigweed, Powell amaranth, Palmer pigweed, tall waterhemp, tropical spiderwort.

*For control of these weeds in corn only, refer to the Corn - Woolly Cupgrass and Wild Proso Millet Control Program section of this label.

Weeds Partially Controlled*: common purslane, eclipta, Florida beggarweed**, hairy nightshade, sandbur, seedling johnsongrass, shattercane, Texas panicum***, volunteer sorghum, wild proso millet, and woolly cupgrass. *See General Information section. Control of these weeds can be erratic, due partially to variable weather conditions. Control may be improved by following these suggested procedures:

  • Thoroughly till moist soil to destroy germinating and emerged weeds. If CHARGER BASIC is to be applied preplant incorporated, this tillage may be used to incorporate CHARGER BASIC if uniform 2-inch incorporation is achieved as recommended under Application Procedures.
  • Plant crop into moist soil immediately after tillage. If CHARGER BASIC is to be used preemergence, apply at planting or immediately after planting.
  • If available, sprinkler irrigate within 2 days after application. Apply 1/2-1 inch of water. Use lower water volume (1/2 inch) on coarse-textured soils and higher volume (1 inch) on fine-textured soils. Also, refer to the section on Center Pivot Irrigation Application for this method of applying CHARGER BASIC.
  • If irrigation is not possible and rain does not occur within 2 days after planting and application, weed control may be decreased. Under these conditions, a uniform, shallow cultivation is recommended as soon as weeds emerge.

**For partial control of this weed, use a minimum of 1.33 pts./A and apply preemergence.

***For partial control of this weed, use a minimum of 1.33 pts./A and apply through a center pivot irrigation system.
