USE REQUIREMENTS FOR ATRAZINE-CONTAINING PRODUCTS
Atrazine 4L herbicide controls* many annual broadleaf and grass weeds in the crops included on this 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 this 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 this 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 this 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.
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.
Chemigation: Do not apply this product through any type of irrigation system.
Atrazine 4L in water application
Atrazine 4L, a liquefied formulation, should be mixed with water and applied as a spray. Pour Atrazine 4L into the tank during or after filling.
Hydraulic (jet) or mechanical agitation is recommended during mixing and application to keep the materials in suspension. All return lines to the tank must discharge below liquid level and agitation should not be so violent as to cause air bubbles to form in the liquid.
Wash sprayer thoroughly after use.
TANK MIX REQUIREMENTS
When tank-mixing or sequentially applying atrazine and/or simazine or products containing atrazine and/or simazine to Corn or Sorghum, do not exceed a combined application rate of 2.0 pounds combined active ingredient per acre for any single application and the total pounds of atrazine and/or simazine applied (pounds per acre) must not exceed 2.5 pounds combined active ingredient per year. When tank-mixing or sequentially applying atrazine or products containing atrazine to crops other than corn or sorghum, the total pounds of atrazine applied (pounds active ingredient per acre) must not exceed the specific seasonal rate limits as noted in the use directions.
Atrazine 4L in liquid fertilizer applications
Nitrogen solutions or complete liquid fertilizers may replace all or part of the water as a carrier for pre-emergence and preplant applications of Atrazine 4L on corn or sorghum. Mixing should be accomplished as described under water applications. Do not apply after corn or sorghum has emerged as there is danger of liquefied fertilizers causing crop injury.
IMPORTANT - Check the compatibility of this product with liquid fertilizers and/or nitrogen solutions before use. Prepare the proposed mixture on a small scale and evaluate its suitability for spraying before mixing a large quantity.
Dry Bulk Fertilizer Impregnation Uses:
- Impregnation of bulk fertilizer is restricted to commercial facilities. On-farm fertilizer impregnation is prohibited.
- No more than 500 tons of dry bulk fertilizer can be impregnated per day.
- No single facility may impregnate fertilizer with this product for more than 30 days per calendar year.
- The commercial facility impregnating the dry bulk fertilizer must inform, in writing, the user (applicator) of the dry bulk fertilizer that:
- Applicators must wear long-sleeved shirt, long pants, shoes and socks.
- The restricted entry interval is 12 hours.
Application in water plus emulsifiable oil or oil concentrate
Adding emulsifiable oil or oil concentrate to postemergence water-based sprays may improve weed control in corn and sorghum.
However, under certain conditions, use of either emulsifiable oil or oil concentrate may seriously damage corn or sorghum. To minimize this possibility, follow directions, procedures, and use precautions below. Use a crop oil designed for use with this product containing 1 to 2% suitable emulsifier, or a suitable crop oil concentrate designed for use with this product and containing not more than 20% emulsifier or surfactant blend. Several oils and crop oil concentrates of these types are on the market. Emulsifiable oil and oil concentrate contaminated with water or other materials can cause compatibility problems and/or crop injury.
Use Precautions for Application of Atrazine 4L plus Emulsifiable Oil or Oil Concentrate in Water to Corn and Sorghum
- Do not use oil in Atrazine 4L sprays when crop is under stress from prolonged cold, wet weather, poor fertility or other factors or when crop is wet and succulent from recent rainfall as crop injury may occur.
- Do not use oil in Atrazine 4L sprays when treating inbred lines or any breeding stock as injury may occur.
- Adding other insecticides, herbicides, liquid fertilizers or other materials is not recommended because they may cause compatibility problems or crop injury.
- Store and handle emulsifiable oil carefully. Oil contaminated with even a small amount of water may not emulsify properly when added to the tank.
- Do not make more than one application of Atrazine 4L and emulsifiable oil in water per season.
Mixing procedures - all uses:
1. Be sure sprayer is clean and not contaminated with other products like 2,4-D or other materials, as crop injury may result.
2. Fill tank 1/2 to 2/3 full with clean water.
3. Start agitation.
4. Pour product directly from container into tank.
5. Add emulsifiable oil, or oil concentrate, or a tank mix herbicide.
6. Finish filling tank with water, nitrogen solution, or liquid fertilizer.
7. Empty tank as completely as possible before refilling to prevent buildup of oil or emulsifiable concentrate residue in tank. Maintain agitation to avoid separation of other materials from water, nitrogen solution, or liquid fertilizer remaining in tank.
8. If an oil or oil concentrate film starts to build up in tank, drain it, and clean with strong detergent solution or solvent.
9. Clean sprayer thoroughly immediately after use by flushing system with water containing a detergent.
10. For liquid nitrogen or liquid fertilizer, use suction screens of 16-mesh or coarser.
ROTATIONAL CROP DIRECTIONS FOR ALL USES
- Land treated with Atrazine 4L should not be planted to any crop except corn or sorghum until the following year or injury may occur.
- If Atrazine 4L is applied after June 10, do not rotate with crops other than corn or sorghum the next year or injury may occur.
- In the High Plains and Intermountain areas of the West where rainfall is sparse and erratic or where irrigation is required, use Atrazine 4L only when corn or sorghum is to follow corn or sorghum, or a crop of untreated Sorghum or Corn is to precede other rotational crops.
- In Western Minnesota and Eastern parts of the Dakotas, Nebraska, and Kansas, corn or sorghum treated with Atrazine 4L should not be followed with Soybeans if the broadcast rate applied was more than 4.0 pints per acre (or comparable rate in a band) or injury may occur.
- Injury may occur to Soybeans planted in North Central Iowa and South Central Minnesota the year following an Atrazine 4L application on Harps, Canisteo, Stroden or other soils having calcareous surface layer.
- Do not plant sugar beets, tobacco, vegetables, (including dry beans), spring-seeded small grains or small-seeded legumes and grasses the year following Atrazine 4L application or injury may occur.
