SOYBEANS - PREPLANT SURFACE - MEDIUM
Observe all precautions and limitations on the labels of each product used in tank mixtures. Tank mixtures are permitted only in those states where the tank mix partner is registered. Refer to and follow the label for each tank mix product used for precautionary statements, directions for use, geographic and other restrictions.
CHARGER BASIC is a selective herbicide recommended as a preplant surface-applied, preplant incorporated, or preemergence treatment in water or fluid fertilizer for control of most annual grasses and certain broadleaf weeds in corn (all types), cotton, grasses grown for seed, peanuts, pod crops, potatoes, safflowers, sugar beets, sunflowers, grain or forage sorghum, soybeans, and tomatoes.
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 non-target crops, unless at least 1/2 inch of rainfall has occurred between application and the first irrigation.
Where directions specify a CHARGER BASIC tank mixture with AAtrex formulations, other brands of atrazine may be used. Follow the rates, recommendations, and limitations on the AAtrex or respective atrazine product label if other brands of atrazine are used.
Note: Certain states may have established rate limitations for atrazine within specific geographical areas. Consult your state lead pesticide control agency for additional information. It is a violation of the label to deviate from state use regulations.
If CHARGER BASIC is incorporated, any supplemental tillage before planting must not exceed the depth of incorporation.
Dry weather following preemergence application of CHARGER BASIC or a tank mixture may reduce effectiveness. Cultivate if weeds develop.
Where reference is made to weeds partially controlled, partial control can either mean erratic control from good to poor, or consistent control at a level below that generally considered acceptable for commercial weed control.
Precaution: Injury may occur following the use of CHARGER BASIC under abnormally high soil moisture conditions during early development of the crop.
SOIL TEXTURES AND HERBICIDE RATES
Within rate ranges in the rate tables and elsewhere on the label, use the lower rate on soils relatively coarse-textured or low in organic matter; use the higher rate on soils relatively fine-textured or high in organic matter.
Note: CHARGER BASIC may be applied preemergence alone, or in combination with tank mix partners specified on the label, following preplant incorporated herbicides when used according to their label recommendations, provided that such use is not prohibited on the respective labels.
Thoroughly clean sprayer or other application device before using. Dispose of cleaning solu¬tion in a responsible manner. Do not use a sprayer or applicator contaminated with any other materials, or crop damage or clogging of the application device may result.
Weeds Partially Controlled: common purslane, eclipta, , hairy night¬shade, sandbur, seedling johnsongrass, shattercane, ,volunteer sorghum, wild proso millet, and woolly cupgrass.
Florida beggarweed - For partial control of this weed, use a minimum of 1.33 pts./A and apply preemergence.
Texas panicum - For partial control of this weed, use a minimum of 1.33 pts./A and apply through a center pivot irrigation system.
- 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.
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 the 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 the 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.
For information on applying in lower volumes of carrier, see Low Carrier Application section.
For application by air or through center pivot systems, see Aerial Drift Management and Aerial Drift Reduction Advisory Information sections.
For information on impregnating dry fertilizer, see Dry Bulk Granular Fertilizers section.
For information on application using variable-rate technologies, see Variable-Rate Application section.
LOW CARRIER APPLICATION
For Broadcast Ground Application Only
Use sprayers, such as, Hagie, John Deere Hi-Cycle, Melroe Spra-Coupe, or Willmar Air Ride®, that provide accurate and uniform application. Only water may be used as a carrier. Screens in suction and in-line strainers should be 50-mesh. Manufacturers may require that tip screens as fine as 100-mesh be used with some nozzles. Use a pump with capacity to: (1) maintain up to 35-40 psi at the nozzles, and (2) provide sufficient agitation in tank to keep mixture in suspension. Use a minimum of 5.0 gals. of spray mixture per acre. Maximum recommended sprayer speed is 15 mph. Rinse sprayer thoroughly with clean water immediately after each use.
Note: Low pressure nozzles are recommended to reduce drift and increase application accuracy. Care should be taken when using automatic rate controlling devices to spray the material within the rated working pressure and flow ranges of the nozzles selected. Nozzle screens should be used when recommended by the manufacturer. All nozzles should be placed on 20-inch centers, except flooding types which should be placed on 40-inch centers. When Flat Fan-type nozzles are used, angles of 80° or 110° are recommended. Always read and follow the manufacturer’s directions for optimum setup and performance of their nozzles or tips.
Apply CHARGER BASIC in water alone or in tank mixtures with AAtrex, Lexone, Lorox, or Sencor in a minimum total volume of 2.0 gals./A by aircraft. CHARGER BASIC may also be applied by air in combination with Balan, Framework or Trust. Avoid application under conditions where uniform coverage cannot be obtained or where excessive spray drift may occur. In order to assure that spray will be controllable within the target area when used according to label directions, make applications at a maximum height of 10 ft., using low-drift nozzles at a maximum pressure of 40 psi, and restrict application to periods when wind speed does not exceed 10 mph. To assure that spray will not adversely affect adjacent sensitive nontarget plants, apply CHARGER BASIC alone or CHARGER BASIC + AAtrex by aircraft at a minimum upwind distance of 400 ft. from sensitive plants, or apply CHARGER BASIC + Lexone, Lorox, or Sencor at a minimum upwind distance of 300 ft. from sensitive plants.
Apply 200-700 lbs. of the herbicide/fertilizer mixture per acre. For best results, apply the mixture uniformly to the soil with properly calibrated equipment immediately after blending. Uniform application of the herbicide/fertilizer mixture is essential to prevent possible crop injury. Nonuniform application may also result in unsatisfactory weed control. In areas where conventional tillage is practiced, a shallow incorporation of the mixture into the soil may improve weed control. On fine- or medium-textured soils in areas where soil incorporation is not planned, i.e., reduced tillage situations or in some conventional till situations, make applications approximately 30 days before planting to allow moisture to move the herbicide/fertilizer mixture into the soil. On coarse-textured soils, make applications approximately 14 days prior to planting.
Precaution: To avoid crop injury, do not use the herbicide/fertilizer mixture on crops where bedding occurs.
Variable-Rate Broadcast Ground Application for Corn and Soybeans
Variable-rate technologies may be used for more precise applications. Two additive factors have been determined for use in applications using variable-rate technologies. One of these factors (A) is directly related to soil texture and the other (B) is related to percent organic matter (OM) and soil texture. When these two factors are added together, the resulting application rate will be more precise for a soil of a given soil texture and organic matter content. Use the formulas below to assure a more precise rate for any given area within a field.
Refer in the label for tank mix information.
SOYBEANS – CHARGER BASIC ALONE
Apply CHARGER BASIC, either preplant surface-applied, preplant incorporated, or preemergence, or as a postemergence using the appropriate rate specified below. Preplant Surface-Applied, Preplant Incorporated, or Preemergence: Follow instructions for use of CHARGER BASIC alone under Application Procedures.
- Apply after September 30 in ND, SD, MN, WI, and north of Route 30 in IA.
- Apply after October 15 north of Route 91 in NE and south of Route 30 in IA.
- Apply after October 31 north of Route 136 in IL.
In all locations, apply to crop stubble after harvest when the sustained soil temperature at a 4-inch depth is less than 55° F and falling. In minimum-till or no-tillage systems on soils having greater than 2.5% organic matter, use 1.67-2.0 pts./A on medium-textured and 2.0 pts./A on fine-textured soils. Do not apply to frozen ground. A tillage operation may precede the application. A fall and/or a spring tillage may follow application, but do not exceed an incorporation depth greater than 2-3 inches. Minimize furrow and ridge formation in the tillage operations. Note: If a spring application is made, the total rate of the fall plus spring applications must not exceed the maximum total rate for soybeans, or illegal residues may result.
Note: On soybeans, CHARGER BASIC may be used up to 2.6 pts./A as a preplant surface-applied, preplant incorporated, or preemergence treatment on soils having an organic matter content between 6% and 20%. The total CHARGER BASIC rate applied to soybeans during any one crop should not exceed 2.6 pts./A. Do not graze or feed treated soybean forage, hay, or straw to livestock 30 days following treatment, or illegal residues may result.
