Active materials

Bicep II Magnum is a selective herbicide recommended for preplant, preemergence, or postemergence control of most annual grasses and broadleaf weeds in corn. Bicep II Magnum 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 by the seed company with Concep. This product may be tank mixed with other herbicides for weed control in conventional, minimum-till, and no-till corn, grain sorghum, or forage sorghum.
Note: Tank mixtures are permitted only in those states where the tank mix partner is registered. Refer to and follow the label of each tank mix product used for precautionary statements, directions for use, geographic and other restrictions.
When tank mixing or sequentially applying atrazine or products containing atrazine to corn or sorghum, do not exceed an application rate of 2.0 pounds active ingredient of atrazine per acre for any single application and the total pounds of atrazine applied (lb ai per acre) must not exceed 2.5 pounds active ingredient per acre per year.
Following many years of continuous use of atrazine (one of the ingredients in Bicep II Magnum), and products chemically related to atrazine, biotypes of some of the weeds listed on this 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, we recommend the use of Bicep II Magnum in combination or in sequence with registered herbicides which do not contain triazines. Consult with your State Agricultural Extension Service for specific recommendations.
Precautions: (1) If sorghum seed is not properly pretreated with Concep, Bicep II Magnum will severely injure the crop. (2) Injury may occur to sorghum following the use of Bicep II Magnum under abnormally high soil moisture conditions during early development of the crop.
Bicep II Magnum alone or in tank mixture with AAtrex, Balance, Dual Magnum, Dual II Magnum, or Princep may be applied early preplant, preplant surface, preplant incorporated, or preemergence on corn, in water or fluid fertilizer. Apply postemergence treatments of Bicep II Magnum to corn, alone or in combination, using water only as the carrier. Bicep II Magnum may be applied in tank mix combination with Gramoxone brands, Landmaster BW, Touchdown, or Roundup with or without the above herbicides preplant surface or preemergence to corn.
Bicep II Magnum alone may also be applied on sorghum early preplant, preplant incorporated, preplant surface, or preemergence in water or in fluid fertilizer.
Bicep II Magnum may be applied in water by aircraft. Applications in fluid fertilizer should be only by ground equipment.
To avoid spray drift, do not apply under windy conditions. Avoid spray overlap, as crop injury may result.
Do not apply this product 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:
1. 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.
2. Do not apply to impervious substrates, such as paved or highly compacted surfaces.
3. 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.
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.
Dry weather following preemergence application of Bicep II Magnum or a tank mixture may reduce effectiveness.
Cultivate if weeds develop in conventional tillage corn or sorghum.
Observe all precautions and limitations on the label of each product used in tank mixtures.
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 sprayer clogging of the application device may occur.

Important: Always read and follow label instructions when buying or using this product.
