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.
Dual II Magnum 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 beans, peas, and lentils; corn (all types); cotton; grasses grown for seed; peanuts; potatoes; safflowers; sweet, grain, or forage sorghum; soybeans; soybean, immature seed; sugar beets; sunflowers; and tomatoes.
Restrictions: 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:
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 directions specify a Dual II Magnum 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.
Restrictions: 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 this label to deviate from state use regulations.
If Dual II Magnum is incorporated, any supplemental tillage before planting must not exceed the depth of incorporation.
Dry weather following preemergence application of Dual II Magnum 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 Dual II Magnum under abnormally high soil moisture conditions during early development of the crop.

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