CORN - WEEDS PARTIALLY CONTROLLED - PREEMERGENCE APPLICATION - 3% OM OR GREATER THAN
Lumax may be used preemergence and postemergence in the culture of field corn, field seed corn, and field corn silage. Lumax may also be used in the culture of sweet corn, yellow popcorn, and grain sorghum, but the application must be made prior to crop emergence, (i.e., preemergence) or severe crop injury may occur.
Lumax is a unique combination of the herbicides: S-metolachlor, mesotrione, and atrazine plus the safener benoxacor. Lumax controls weeds by interfering with normal germination and seedling development. It is recommended for management of the weed species listed in Tables 1 and 2 of the label.
Read all label directions before using.
Atrazine Herbicide Rate Limitations
Certain states may have established rate limitations within specific geographical areas for the use of atrazine. These more restrictive/protective requirements must be followed. Consult your state lead pesticide control agency for additional information. It is a violation of the label to deviate from state use regulations.
- When tank mixing or sequentially applying atrazine or products containing atrazine with Lumax to corn, 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. a.i. per acre) must not exceed 2.5 pounds active ingredient per acre per year.
- Maximum broadcast application rates for atrazine in corn must be as follows:
- If no atrazine was applied prior to corn emergence, apply a maximum of 2.0 lbs. a.i./A broadcast. If a postemergence treatment is required following an earlier herbicide application, the total atrazine applied may not exceed 2.5 lbs. a.i./A per calendar year.
- Apply a maximum of 2.0 lbs. a.i./A as a single preemergence application on soils that are not highly erodible or on highly erodible soils (as defined by the Natural Resource Conservation Service) if at least 30% of the soil is covered with plant residues.
- Apply a maximum of 1.6 lbs. a.i./A as a single preemergence application on highly erodible (as defined by the Natural Resource Conservation Service) soils if <30% of the surface is covered with plant residues or 2.0 lbs. a.i./A if only applied postemergence.
Note: For purposes of calculating total atrazine active ingredient applied, Lumax contains 1.0 lb. a.i. atrazine plus relateds per gallons.
- Grazing Restriction: To avoid possible illegal residues, do not graze or feed forage from treated areas for 45 days following application.
- Preharvest Interval (PHI): Field corn may be treated up to 12 inches tall. Do not harvest forage, grain, or stover within 60 days after application. Do not harvest sweet corn forage within 45 days after application.
- 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:
- 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 tail water 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 Lumax or a Lumax tank mixture may reduce effectiveness. Cultivate if weeds develop in conventional tillage corn.
- 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.
- This product will not provide consistent control of emerged grass weeds.
- Do not apply more than 3 qts. of Lumax per acre per growing season.
- Do not apply other solo HPPD inhibitor postemergence herbicides (Callisto, Impact, or Laudis) to ground that has been treated with Lumax in the same season.
- Applying Lumax postemergence (emerged corn) to corn that has received an at-plant application of Counter insecticide can result in severe corn injury. Temporary corn injury may occur if Lumax is applied to emerged corn where organophosphate insecticides other than Counter were applied at planting.
- Do not make postemergence (emerged corn) applications of Lumax in a tank mix with any organophosphate or carbamate insecticide, or severe corn injury may occur.
- Postemergence (emerged corn) applications of any organophosphate or carbamate insecticide within 7 days before or 7 days after a Lumax application may result in severe corn injury.
- Do not use Lumax on any crop other than field corn (for grain, seed, or silage), sweet corn (preemergence applications only), yellow popcorn (preemergence applications only), or grain sorghum (preemergence applications only).
- Do not use Lumax in the culture of white popcorn or ornamental (Indian) corn or injury may occur.
- Do not contaminate irrigation water used for crops other than field corn or water used for domestic purposes.
- Avoid drift onto adjacent crops.
- Avoid spray overlap, as crop injury may result.
- Do not allow Lumax to contaminate feed or food.
- Do not store Lumax near seeds, fertilizers, or foodstuffs.
- All containers of Lumax must be kept tightly closed when not in use.
- Do not use aerial application to apply Lumax.
- Do not apply Lumax to sweet corn or yellow popcorn after the crop has emerged or severe crop injury may occur.
Applied according to directions and under normal growing conditions, Lumax will not harm the treated crop. During germination and early stages of growth, extended periods of unusually cold and wet or hot and dry weather, insect or plant disease attack, carryover pesticide residues, the use of certain soil applied systemic insecticides, improperly placed fertilizers or soil insecticides, may weaken crop seedlings. Lumax used under these conditions could result in crop injury.
INTEGRATED PEST (WEED) MANAGEMENT
Lumax may be integrated into an overall pest management strategy. Practices known to reduce weed development (tillage, crop competition) and herbicide use (weed scouting, proper application timing, banding, and rotations) should be followed wherever possible. Consult local agricultural and weed authorities for additional Integrated Pest Management strategies established for your area.
SOIL ORGANIC MATTER
The organic matter of the soil on which the application is to be made must be known or determined prior to application. The use rate of Lumax is based on percent soil organic matter.
REDUCED AND NO-TILL SYSTEMS
Lumax may be used in reduced and no-till systems. The highest levels of control will be obtained when applications are made as close to planting as possible. It is recommended that a burndown herbicide such as Gramoxone Inteon, Touchdown brands, Roundup brands, or 2,4-D be tank mixed with Lumax in reduced or no-till systems if weeds are present at application and the corn has not yet emerged.
Preemergence: Apply in a spray volume of 10-80 gals./A.
Lumax may be applied to the soil surface as a broadcast or banded application.
Banded Preemergence: Lumax may be applied in a 10- to 15-inch band after corn planting but prior to corn emergence. Follow formula on the label.
Do not apply more than 14 days prior to planting or to field corn higher than 12 inches tall. Lumax is not recommended on soils with greater than 10% organic matter, or poor weed control may result.
Thoroughly till soil or make an application of a burndown herbicide to destroy germinating and emerged weeds. Plant crop into moist soil immediately after tillage.
If a significant rainfall does not occur within 7 days after application, weed control may be decreased. If irrigation is available, apply 1/2 to 1 inch of water. If irrigation is not available, a uniform shallow cultivation is recommended as soon as weeds emerge.
