CORN - POSTEMERGENCE BROADCAST - FINE
Charger Max ATZ is a selective herbicide for use before planting, or before or after crop emergence (see specific directions) for control of most annual grasses and broadleaf weeds in corn. Charger Max ATZ can also be used before crop emergence for control of most annual grasses and broadleaf weeds in grain or forage sorghum, provided the sorghum seed has been properly treated with Concep Charger Max ATZ may also be tank mixed with other herbicides as specified on the label for weed control in conventional, minimum till, and no till corn, grain sorghum, or forage sorghum. 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 most restrictive label directions for all tank mix products used.
When tank mixing or sequentially applying Atrazine or any product containing atrazine to corn or sorghum, do not exceed a total rate of 2 lb of atrazine active ingredient per acre in any one application, and do not exceed a total rate of 2.5 lb. atrazine active ingredient per acre in any one year.
Following many years of continuous use of atrazine (one of the active ingredients in Charger Max ATZ) or products chemically related to atrazine, biotypes of some weeds listed on the label which are controlled by the atrazine component have been reported to develop resistance to this and chemically related herbicides. Where this is known or suspected, and weeds controlled by this product are expected to be present along with resistant biotypes, use Charger Max ATZ in combination or in sequence with registered herbicides which do not contain triazines. Consult your State Agricultural Extension Service for specific recommendations.
Precautions: If sorghum seed is not properly treated with Concep, Charger Max ATZ will severely injure the crop. Injury may occur to sorghum following the use of Charger Max ATZ under abnormally high soil moisture conditions during early development of the crop.
Charger Max ATZ alone or in tank mixture with atrazine, simazine, Balance, or Charger Max may be applied early preplant, preplant surface, preplant incorporated, or preemergence on corn in water or fluid fertilizer. Apply postemergence treatments of Charger Max ATZ to corn, alone or in combination, using only water as the carrier.
Charger Max ATZ may be applied in tank mix combination with paraquat (e.g. Gramoxone MAX), Cornerstone (glyphosate), or Landmaster BW preplant surface or pre-emergence to corn. Charger Max ATZ may also be applied on sorghum early preplant, preplant incorporated, preplant surface, or pre-emergence in water or in fluid fertilizer.
Charger Max ATZ may be applied by aircraft in water only. Do not dilute in fluid fertilizer for aerial application.
To avoid drift, do not apply under windy conditions. Avoid spray overlap, as crop injury might result.
Do not apply through any type of irrigation system.
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 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 first irrigation.
Where reference is made to weeds partially controlled, partial control can mean either erratic control from good to poor, or consistent control at a level below that generally considered to be acceptable for commercial weed control.
Dry weather following pre-emergence application of Charger Max ATZ alone or in tank mixture may reduce effectiveness. Cultivate if weeds develop in conventional tillage corn or sorghum.
Thoroughly clean sprayer or other application device before using. Dispose of cleaning solution in a responsible manner. Do not use a sprayer or applicator contaminated with other materials or crop damage or clogging of the application device might occur.
Within rate ranges in the rate tables and elsewhere in the label, use the lower rate on soils that are relatively coarse textured or low in organic matter. Use the higher rate on soils that are relatively fine textured, or high in organic matter.
Charger Max ATZ may be applied pre-emergence alone or in tank mixtures as specified in the label following pre-plant incorporated herbicides used according to their label directions, provided such use is not prohibited by those labels.
Control of escaped weeds with cultivation or an application of an appropriate EPA registered post-emergence herbicide. On fine-textured soils, only partial control can be expected.
1. In corn, apply up to the maximum single application rate in Table 1 for your given soil texture and rate limitations based on your soil conservation practices.
2. Thoroughly till moist soil to destroy germinating and emerged weeds. If Charger Max ATZ is to be applied pre-plant incorporated, this tillage may be used to incorporate Charger Max ATZ if uniform 2 inch incorporation is achieved as recommended under Application Procedures.
3. Plant crop into moist soil immediately after tillage. If Charger Max ATZ is used pre-emergence, apply at planting or immediately after planting.
4. If available, sprinkler irrigate within 2 days after application Apply 1/2 to 1 inch of water. Use the lower water volume on coarse textured soils, and the higher water volume on fine-textured soils.
5. 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 as soon as weeds emerge is recommended.
For all soil applications prior to crop emergence:
On highly erodable land (as defined by the Natural Resources Conservation Service)
If conservation tillage is practiced, leave at least 30% of the soil surface covered with plant residue, at planting, and apply a maximum of 2.6 quarts per acre as a broadcast spray. Refer to “B” in the following tables.
If the soil covered with plant residue is less than 30% at planting, a maximum of 2.1 quarts per acre may be applied. Refer to “A” in following tables.
On land not defined as highly erodable
Apply a maximum of 2.6 quarts per acre as a broadcast spray. Refer to “B” in following tables.
For post-emergence application to corn:
If no atrazine was applied prior to corn emergence, apply a maximum of 2.6 quarts per acre broadcast. If a post-emergence treatment is required following an earlier herbicide application,, the total atrazine applied may not exceed 2.5 lb active ingredient per acre per calendar year (equivalent to 2.3 quarts per acre of Charger Max ATZ.)
Where there are state and/ or local requirements regarding atrazine use, including lower maximum rates and/ or greater setbacks, which are different from the label, the more restrictive / protective requirements must be followed. Certain states may have established rate limitations within specific geographic areas. Consult your state lead pesticide control agency for additional information. It is a violation of the label to deviate from state use regulations.
(For purposes of calculating total atrazine applied due to use of this product and / or other atrazine products, Charger Max ATZ contains 3.1 lb per gal. (0.775 lb per quart) of atrazine and related compounds.)
Refer in the label for tank mix information.
Postemergence Broadcast - Corn:
Apply early postemergence at the rate indicated in the following rates table. Weeds controlled are listed in the following “Weeds Controlled” table. Apply before grass and broadleaf weeds exceed the 2-leaf stage of growth, and before the corn is more than 5 inches tall. DO NOT USE THE POST-EMERGENCE TREATMENT USING FLUID FERTILIZER AS CARRIER, OR CROP INJURY MIGHT RESULT. Application after weeds are past the 2-leaf stage will not provide satisfactory control. Some leaf-burn may be seen in corn, but this is not expected to affect later growth or yield.
NOTE: To avoid possible illegal residues, do not feed or graze forage from treated areas for 30 days after treatment, and do not harvest sweet corn ears for 30 days after treatment.
NOTES: If Charger Max ATZ (or equivalent product such as Bicep II Magnum) has been applied early preplant, preplant surface, preplant incorporated, or pre-emergence, do not exceed a total of 3.25 quarts per acre on a corn crop. If atrazine or combination products containing atrazine have been applied early preplant, preplant surface, preplant incorporated, or pre-emergence, do not exceed a total of 2.5 lb. of atrazine as active ingredient, or illegal residues might result.
