CORN - CONSERVATION OR MINIMUM TILLAGE - COARSE SOIL TEXTURE
Precautions and Restrictions
- Rotate to sunflower, cotton, soybeans, peanuts, dry beans, lima beans and the following cereal grain crops (except rice)—corn (all types), sorghum, wheat, barley, buckwheat, millet (pearly and proso), oats, rye, teosinte, triticale and wild rice. You may also rotate to the following non-grass animal feed crops—alfalfa, clover spp., lespedeza spp., lupin spp., sainfoin, trefoil spp., vetch spp., crown vetch and milk vetch spp. Other crops may be planted after completion of the rotational crop season.
- If applied after June 10, do not rotate to crops other than corn or sorghum the next year or crop injury from atrazine may occur.
- Injury may occur to soybeans planted the year following application on soils having a calcareous subsurface layer.
- In the High Plains and Intermountain regions of the West where rainfall is sparse and erratic or irrigation is required, use only when corn or sorghum is to follow corn.
- In Eastern parts of the Dakotas, Kansas, Western Minnesota and Nebraska, do not rotate to soybeans if the rate applied to corn was more than 2.0 pounds active ingredient equivalent of atrazine or soybean injury may occur.
- Do not plant sugar beets, sunflower, potatoes, tobacco, dry beans or peas, spring-seeded small grains or small-seeded legumes the year following application, or injury from atrazine may occur.
- Do not apply more than 4 pounds of alachlor active ingredient per acre per year. This is equivalent to 6.4 quarts of this product per acre per year.
Lariat flowable herbicide is recommended for the control of many annual grasses and broadleaf weeds. The seedbed should be fine, firm and free of clods when tillage is performed.
Performance is improved when moisture occurs within one week after application. The amount required depends primarily upon the amount of soil moisture in the weed germination zone at the time of application, soil type and organic matter content, but 1/3 to 3/4 inch is generally sufficient for performance of this product. High intensity or excessive rainfall, or excessive irrigation after application may reduce control.
This product and all tank mixtures listed for corn and grain sorghum in the “DIRECTIONS FOR USE” section may be applied in water or sprayable fluid fertilizer solution prior to crop emergence. Post emergence application to corn is not allowed.
Read and carefully observe the cautionary statements and all other information appearing on the label and on the labeling of all products used in mixtures and sequential treatments.
Use of this product in any manner not consistent with the label may result in injury to persons, animals or crops, or other unintended consequences. Keep container closed to prevent spills and contamination.
Do not apply when conditions favor drift.
Flush sprayer with clean water after use.
NOTE: Use this product for weed control in corn and grain sorghum (milo) only. CORN, PEANUTS, SORGHUM (MILO) OR SOYBEANS CAN BE PLANTED THE YEAR FOLLOWING THE USE OF THIS MIXTURE. IF SOYBEANS, PEANUTS, OR DRY BEANS ARE PLANTED THE FOLLOWING YEAR, THERE IS THE POSSIBILITY OF CROP INJURY DUE TO CARRYOVER OF ATRAZINE. Do not plant soybeans in areas where furrow irrigation is practiced.
Applicators should evaluate soil and weed conditions carefully to assure that they choose the lowest effective label rate.
The application rates of this product and the other herbicides labeled for use in tank mixtures with this product generally vary with soil texture. Unless soil texture is specifically named, rate tables throughout the label refer to only three soil textural groups: coarse, medium and fine.
Do not apply this product through any type of irrigation system.
When tank mixing or sequentially applying atrazine or products containing atrazine to corn or sorghum, the total pounds of atrazine applied (pounds active ingredient per acre) must not exceed 2.5 pounds active ingredient per year.
Postemergence applications to corn and sorghum must be made before crop reaches 12 inches in height.
The maximum broadcast application rates for corn:
- If no atrazine was applied prior to corn emergence, apply a maximum of 2 pounds active ingredient per acre broadcast. If a postemergence treatment is required following an earlier herbicide application, the total atrazine applied may not exceed 2.5 pounds active ingredient per acre per calendar year.
- Apply a maximum of 2.0 pounds active ingredient per acre as a single preemergence application on soils that are not highly erodible or on highly erodible soils (as defined by the Natural Resources Conservation Service) if at least 30 percent of the soil is covered with plant residues, or
- Apply a maximum of 1.6 pounds active ingredient per acre as a single preemergence application on highly erodible soils (as defined by the Natural Resources Conservation Service) if less than 30 percent of the surface is covered with plant residues; or 2.0 pounds active ingredient per acre if only applied postemergence.
Aerial—Fixed wing; Helicopter: Apply this product or approved tank mixtures in 3 to 10 gallons of water per acre. AVOID DRIFT. DO NOT APPLY DURING INVERSION CONDITIONS, WHEN WINDS ARE GUSTY, OR UNDER ANY OTHER CONDITIONS WHICH WILL ALLOW DRIFT.
Mixers and loaders supporting aerial applications are required to use a mechanical transfer system designed by the manufacturer to transfer liquid pesticide in a manner that prevents the liquid (but not necessarily any vapor) from contacting handlers or other people during the transfer. The closed system must be used in a manner that meets the requirements listed in the Worker Protection Standard (WPS) for agricultural pesticides [40 CFR 170.240 (d)(4)].
Coarse sprays are less likely to drift; therefore, do not use nozzles or nozzle configurations which dispense fine spray droplets. Do not angle nozzles forward into the airstream and do not increase spray volume by increasing nozzle pressure. Ensure uniform application. To avoid streaked, uneven or overlapped application, use mechanical marking systems.
Ground Broadcast Treatment: Apply this product or approved tank mixtures in 10 or more gallons of water or sprayable fluid fertilizer per acre. Do not apply during periods of gusty winds or winds in excess of 15 miles per hour.
Band Treatment: Apply a broadcast equivalent rate and volume per acre to determine these.
Mount spray equipment on the planter with nozzles behind press wheel and apply this product at planting time.
APPLICATION TIMING AND METHODS
Early Preplant Surface: This product and some labeled tank mixtures of this product may be applied to no-till and other conservation tillage systems before weeds emerge and up to 45 days before planting. Split applications can be made 30 to 45 days prior to planting, with 60 percent of the broadcast rate applied initially and the remaining 40 percent applied at planting. Applications made less than 30 days prior to planting can be made either as a split or single application. If weeds are present at the time of application, apply this product in tank mixture with an appropriate contact herbicide. Observe direction for use, precautions and restrictions on the label of the contact herbicide. During the planting operation, be careful not to move untreated soil to the surface or move treated soil out of the row, as weed control may be reduced.
Preplant Incorporation: This product and many of the labeled tank mixtures may be mixed into the soil using shallow incorporation equipment any time within 7 days prior to planting. Refer to the crop to be treated in the “DIRECTIONS FOR USE’’ section of the label to determine if preplant incorporation is recommended. Apply to the soil surface as a broadcast application. Precipitation or irrigation is required to bring incorporated herbicide treatments into contact with germinating weed seedlings.
The amount of precipitation or irrigation required depends on existing soil moisture, soil type and percent organic matter content, but 1/3 to 3/4 inch is normally adequate. If weeds emerge after treatment, rotary hoe or shallowly cultivate immediately to improve performance.
NOTE: Do not incorporate unless specifically recommended in the label for the crop and herbicide treatment selected. Incorporation of this product and its labeled tank mixtures on coarse soil types may reduce length of weed control due to leaching with rainfall or irrigation. Incorporation is not recommended on coarse soils in the southeastern states.
Shallowly incorporate the treatment into the upper 1 to 2 inches of the soil. Equipment should be operated at manufacturer’s designed speed for incorporation to ensure adequate mixing and distribution of the herbicide treatment in the soil. Equipment design including any drag attachments must be adequate to avoid soil ridging which may result in streaked or reduced weed control. Set equipment to work the soil NO DEEPER THAN 4 INCHES. Soil conditions, including moisture content and crop residue levels, must be suitable to allow thorough and uniform mixing.
Preemergence Surface Application: This product and all labeled tank mixtures may be applied to the soil surface after planting and prior to either crop or weed emergence, apply within 5 days of last preplant tillage. If weeds emerge after treatment, or if treatment is applied more than 5 days after last preplant tillage, rotary hoe or shallowly cultivate immediately to improve performance. Precipitation or overhead sprinkler irrigation is required after application to move the herbicide treatment into the weed germination zone. The amount of precipitation or overhead sprinkler irrigation required depends on existing soil moisture, soil type and percent organic matter content, but 1/3 to 3/4 inch is normally adequate. Performance is improved when moisture is received within 7 days after application and prior to weed emergence. High intensity or excessive rainfall or excessive irrigation after application may reduce control.
Cultivation Information: Delay cultivation after application for as long as possible unless weeds or grasses emerge. Shallowly cultivate or rotary hoe immediately if weeds or grasses emerge. If cultivation is necessary because of soil crusting or compaction, set equipment shallow and minimize lateral soil movement to avoid dilution or displacement of the herbicide treatment. If a band application is used and weeds have emerged in the treated band, set cultivator to throw soil into the row, covering the band.
CONSERVATION OR MINIMUM TILLAGE SYSTEMS TANK MIXTURES
When applied as directed under the conditions described, the recommended tank mixtures control many emerged annual weeds, suppress many emerged perennial weeds and give preemergence control of many annual grasses and broadleaf weeds when corn or grain sorghum will be planted directly into a cover crop, stale seedbed, established sod, or in previous crop residues. Consult the “WEEDS CONTROLLED” section of the label to determine the weeds that are controlled or reduced prior to their emergence, and the “WEEDS CONTROLLED” section of the Roundup agricultural herbicide, Gramoxone or 2,4-D herbicide labels to determine the weeds that are controlled or reduced following postemergence treatment by these products. USE OF THESE MIXTURES FOR BERMUDAGRASS OR JOHNSONGRASS CONTROL IS NOT RECOMMENDED.
Apply the recommended tank mixtures BEFORE CROP EMERGENCE. As density of stubble, crop residue or weeds increases, spray volume and rate should be increased within the application rate ranges to ensure complete coverage. In the absence of emerged vegetation, delete the Roundup agricultural herbicide, 2,4-D or Gramoxone herbicide portion of these tank mixtures. Follow the recommendations in the preceding sections of the label and also the label of the contact herbicide that is included in the tank mixture to provide postemergence control of weeds.
APPLY ONLY BY GROUND APPLICATION SYSTEMS. DO NOT APPLY BY AIR.
Attention: AVOID DRIFT—EXTREME CARE MUST BE USED WHEN APPLYING THESE TANK MIXTURES TO PREVENT INJURY TO DESIRABLE PLANTS AND CROPS.
Do not allow spray mist to drift because even minute quantities of spray can cause severe damage or destruction to nearby crops, plants or other areas on which treatment is not intended. Do not apply when winds are gusty or in excess of 5 miles per hour or when other conditions, including lesser wind velocities, will allow drift to occur. When spraying, avoid combinations of pressure and nozzle type that will result in fine particles (mist) that are more likely to drift.
When applied as directed under the conditions described, this product and tank mixtures of this product will control or reduce competition from the weeds listed. Refer to the appropriate crop section of the label to determine the rates and tank mixtures recommended.
Grassbur: When applied at 4 to 5 quarts per acre this product controls this weed. Preemergence surface applications should be applied to a freshly prepared seedbed. Rotary hoe or initiate overhead irrigation (0.33 to 0.55 inch) within 24 hours of application for best control.
Nutsedge yellow: When applied at 5 quarts per acre this product on medium- and fine-textured soils and preplant incorporated only, this product controls this weed. The 5-quart per acre rate is limited to soils not highly erodible and highly erodible soils with more than 30 percent plant residue cover.
Cocklebur : Morningglory annual , Buttonweed: When applied at 4 to 5 quarts per acre this product controls these weeds. Use the higher rate in coarse-textured soils or medium- and fine-textured soils with organic matter content greater than 3 percent.
- When applied at rates of 4 to 5 quarts per acre on a broadcast basis preplant incorporated or immediately after planting and within 5 days of last tillage, this product will reduce competition from the following HARD-TO-CONTROL weeds.
Refer in the label regarding tank mix information.
CORN—CONSERVATION OR MINIMUM TILLAGE(All Types)
NOTE: Important information regarding Conservation or Minimum Tillage appears in the Application Information section at the front of the label and should be carefully reviewed in conjunction with the information in this section.
Each crop section of the label provides treatment rates for this product and tank mixtures including this product. Applications which are not consistent with recommendations in the label may result in unsatisfactory weed control, injury to crops, persons or animals, or other unintended consequences. Refer to specific product labels for crop rotation restrictions and cautionary statements of all products used in these tank mixtures, including precautions on soil pH, sensitive varieties, minimum re-cropping interval and rotational guidelines.
Use the higher rates in the application rate ranges in areas of heavy weed infestation or where otherwise specified. If emerged weeds exist at planting, the application of a contact herbicide or tillage is recommended when possible to eliminate existing weeds. Do not apply when conditions favor drift.
Detailed information regarding Application Systems and Application Timings and Methods should be carefully reviewed in conjunction with the information in this section. If the specific information in this section differs from the PRODUCT INFORMATION, the specific information should control. This product and the following tank mixtures can be tank mixed with Roundup agricultural herbicides, Gramoxone brand herbicides and/or 2,4-D.
DO NOT APPLY BY AIR.
Do not make more than two applications per year or exceed a total of 6.4 quarts of this product per acre per year. If there has been a previous application of a product containing atrazine, do not exceed a total of 2.5 pounds of atrazine active ingredient per acre per calendar year.
Do not make more than one application of this product per year on sweet corn.
For preemergence weed control on highly erodible soils (as defined by the Natural Resources Conservation Service) with less than 30 percent plant residue cover, the maximum rate is 4.25 quarts of this product per acre (1.6 pounds of atrazine active ingredient per acre). On soils not highly erodible or on highly erodible soils with more than 30 percent plant residue cover, the maximum rate is 5.3 quarts of this product per acre (2 pounds atrazine active ingredient per acre).
DO NOT graze treated area or feed treated forage to livestock for 60 days after application to field corn or 45 days after application to sweet corn.
CONTROL OR SUPPRESSION OF EMERGED WEEDS—BURNDOWN PRIOR TO CROP
Roundup Agricultural Herbicides
Annual Weeds: Apply labeled rates of Roundup agricultural herbicides, in these tank mixtures when weeds are less than 6 inches tall.
Perennial Weeds: At normal application dates in minimum tillage systems, perennial weeds may not be at the proper stage of growth for control. Use of labeled rates of Roundup agricultural herbicides, in the above mixtures under these conditions provides top kill and reduces competition from many emerged perennial grasses and broadleaf weeds.
APPROVED APPLICATION SYSTEMS
Ground: Broadcast boom
- Use 4 to 5 quarts of this product per acre in areas of heavy weed infestations. Do not exceed 4.25 quarts of Lariat per acre on highly erodible soils with less than 30 percent plant residue cover.
NOTE: For hard-to-control weeds, additional amounts of Micro-Tech and/or atrazine may be added to the treatment rates for this product to provide improved control. For more consistent control of common cocklebur, annual morningglory or velvetleaf, additional atrazine may be applied so the total atrazine rate is at least 1.5 quarts per acre on medium soil with less than 3 percent organic matter, and 1.5 to 2 quarts on medium and fine soils with 3 percent or greater organic matter content.
