Atrazine 4L herbicide controls* many annual broadleaf and grass weeds in the crops included on the label. Atrazine 4L may be applied before or after weeds emerge.
*Important Note: Following many years of continuous use of this product and chemically related products, biotypes of some of the weeds listed on the label have been reported which cannot be effectively controlled by this and related herbicides. These weeds may include Lambsquarters, Pigweed, Black nightshade, Kochia, and others. Where this is known or suspected, we recommend the use of this product in combination with other registered herbicides which are not triazines. Consult your State Agricultural Extension Service about specific weed resistance to atrazine in your area and weed control recommendations. Within the specific crop directions on the label, certain weeds are indicated for suppression only. Weed suppression is a visual reduction in weed competition (reduced population and/or vigor) as compared to an untreated area. Degree of suppression will vary with rate used, size of weeds, and environmental conditions following treatment.
In each case where a range of rates is given, the lower rate should be used on light soils low in organic matter, and the higher rate should be used on heavy soils high in organic matter.
Since Atrazine 4L acts mainly through root absorption, its effectiveness depends on rainfall or irrigation to move it into the root zone. Should weeds develop, a shallow cultivation or rotary hoeing will generally result in better weed control. Care should be taken to avoid using Atrazine 4L where adjacent desirable trees, shrubs, or plants might be injured.
Note: Loveland Products, Inc. does not recommend the use of Atrazine 4L in combination with other herbicides or oils except as specifically described on the label or other literature distributed by Loveland Products, Inc.
For the most uniform distribution of broadcast applications use 80° flat fan type nozzles. For band applications, use flat fan even spray nozzles. Screens and strainers should be no finer than 50 mesh. Use a pump with capacity to (1) provide sufficient hydraulic agitation during mixing and application to keep the material in suspension and (2) maintain 35-40 psi operating pressure. Use a minimum of 5.0 gallons of water per acre for preplant incorporated, pre-emergence and post (without oil or surfactant) applications. Use a minimum of 10.0 gallons of water per acre for all postemergence applications combined with oil or surfactant.
Refer to the label for band applications to calculate the amount to be applied per acre.
For preplant and pre-emergence broadcast treatments, apply at a 1:1 ratio of Atrazine 4L to water (example: recommendation calls for 1.0 quart of product and is mixed with 1.0 quart of water) to be applied per acre. For postemergence treatments, on corn and sorghum, apply the specified rate of Atrazine 4L or Atrazine 4L plus oil in a minimum of 2.0 gallons of water per acre. Avoid applications under conditions where uniform coverage cannot be obtained or where excessive drift may occur.
Avoid application directly to animals. Flagmen or loaders should avoid inhalation of spray mist.
With fixed-wing aircraft or helicopter application, an exactly even swath deposition cannot be achieved, and consequently crop injury or pesticide nonperformance may result wholly or in part. Do not apply by air during periods of thermal inversion.
Refer to the label for tank mix information.
ATRAZINE 4L may be applied either before planting, at planting or after planting.
For preplant and preemergence applications, nitrogen solutions or complete liquid fertilizers may replace all or part of the water as a carrier of ATRAZINE 4L. Do not apply after corn has emerged as there is danger of liquid fertilizer causing crop injury.
PREPLANT: Broadcast in the spring after plowing.
Apply before, during or after final seedbed preparation. If soil is tilled or worked after application, avoid deep incorporation of ATRAZINE 4L. Best results have been obtained when ATRAZINE 4L is applied within two weeks prior to planting.
PREEMERGENCE: Apply during or shortly after planting prior to weed emergence.
- For Preplant or Preemergence Applications in Western KS, Western NE, Eastern CO, Eastern WY, NM, West TX and the Pan Handle of OK. On sands, loamy sands, sandy loams, mild to strongly alkaline soils and all recently leveled soils, apply 2-2/5 pts. per acre for broadleaf weed control. Broadleaf weeds such as pigweed, lambsquarters, nightshade, purslane and kochia will be controlled. On other soil types in the areas above, make applications at the rate shown on label for broadleaf and grass control.
USE RESTRICTIONS FOR ALL APPLICATIONS 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 (pounds active ingredient per acre) must not exceed 2.5 pounds active ingredient per acre per year.
- Follow a preharvest interval of 60 days for field corn forage use and 45 days for sweet corn forage use.
- Do not graze treated area or feed treated forage to livestock for 21 days following application.
USE PRECAUTIONS FOR ALL APPLICATIONS TO CORN
- Following harvest of a treated crop, plow (moldboard or disk-plow) and thoroughly till the soil in the fall or spring to minimize possible injury to rotational spring-seeded crops, regardless of the rate used.
- For postemergence applications plus emulsifiable oil, see additional use precautions under “Application in water plus emulsifiable oil or oil concentrate.\"
- Postemergence application to Corn must be made before crop reaches 12 inches in height.
Note: For best control of Cocklebur and Velvetleaf, do not apply less than the specified 4.0 pints per acre.
Giant foxtail; Large (hairy) crabgrass; Yellow foxtail; Broadleaf weeds: Cocklebur; Kochia; Lambsquarters; Nightshade; Pigweed: Maximum rate limitations and local resistance may result in suppression only or lack of control. Refer to IMPORTANT NOTE within PRODUCT INFORMATION SECTION of the label.
Grass weeds: Barnyardgrass (watergrass); Green foxtail; Witchgrass (Panicum capillare); Velvetleaf (buttonweed): Suppression or partial control only on medium and fine textured soils.
Field Corn Forage = 60 Days, Sweet Corn = 45 Days
