SORGHUM POSTEMERGENCE WINTER WEED CONTROL IN TEXAS

General Information

PRODUCT INFORMATION

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.

APPLICATION PROCEDURES

Ground Application

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.

Aerial Application

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.

Limitations, Restrictions, and Exceptions

SORGHUM POSTEMERGENCE WINTER WEED CONTROL IN TEXAS

For use on fall bedded land and in the Gulf Coast and Blacklands of Texas. Broadcast 0.8 to 1.0 quart per acre postemergence for control of winter weeds only, such as Henbit, Seedling dock and Annual thistle on land that will be planted to corn, grain sorghum, or forage sorghum the following spring.

For best results, add a suitable surfactant such as X-77 or Activator 90, at a rate of 0.5% of spray volume, an emulsifiable oil at a rate of 1.0% of spray volume, or an oil concentrate at rate of 1.0 quart per acre.

Normal weed control programs may be used in the following corn, grain sorghum, or forage sorghum crop.

Note: Do not plant any crops except Corn, Grain sorghum, or Forage sorghum the spring following this treatment.

Restricted Entry Interval

12 hours

Exception: if the product is soil-injected or soil incorporated, the Worker Protection Standard, under certain circumstances, allows workers to enter the treated area if there will there will be no contact with anything that has been treated.
