CORN AND SORGHUM WEED CONTROL/SUPPRESSION - PREPLANT SURFACE APPLIED, PREPLANT INCORPORATED, OR PREEMERGENCE (OR POSTEMERGENCE AT 2.2 LBS./A WITH OIL)
Atrazine 90 WDG Herbicide controls many annual broadleaf and grass weeds in the crops included on the label. Atrazine 90 WDG Herbicide 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 and soils low in organic matter, and the higher rate should be used on heavy soils high in organic matter.
Since Atrazine 90 WDG Herbicide 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 90 WDG Herbicide where adjacent desirable trees, shrubs, or plants might be injured.
Note: Loveland Products Inc. does not recommend the use of Atrazine 90 WDG Herbicide in combination with other herbicides or oils except as specifically described on the label or supplemental labeling distributed by Loveland Products, Inc.
Ground application: Use conventional ground sprayers equipped with nozzles that provide accurate and uniform application. Be certain that nozzles are uniformly spaced and are the same size. Calibrate sprayer before use and recalibrate at the start of each season and when changing carriers. Unless otherwise specified, use a minimum of 10.0 gallons of spray mixture per acre for all preplant incorporated, preplant surface, preemergence, and postemergence applications (with or without oil or surfactant) with ground equipment.
Refer to the label for band application.
Aerial application is prohibited. 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 atrazine applied (pounds active ingredient per acre) must not exceed 2.5 pounds active ingredient per acre 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.
Aerial application is prohibited.
CORN AND SORGHUM
Broadleaf and grass control: For postemergence control of those weeds listed under Preplant Incorporated and Preemergence, broadcast 2.2 lbs. this product per acre plus emulsifiable oil or oil concentrate after weed emergence, but before weeds reach 1.5 inches in height and before corn is 12 inches tall.
Use precautions for applications with emulsifiable oil or oil concentrate in water: (1) Inbred lines or any breeding stock may be severely injured by applications with emulsifiable oil or oil concentrate. (2) Adding other insecticides, herbicides, liquid fertilizers, or other materials is not recommended, because they may cause compatibility problems or crop injury. (3) Store and handle emulsifiable oil and oil concentrate carefully. Oil contaminated with even a small amount of water may not emulsify properly when added to the tank. To avoid crop injury, (4) Do not apply 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. (5) Do not make more than one application per season.
Note: For best control of Cocklebur and Velvetleaf, do not apply less than the specified 2.2 pounds per acre.
- Giant foxtail, yellow foxtail, 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 GENERAL INFORMATION section of the label.
- Barnyardgrass, green foxtail, witchgrass, velvetleaf: Suppression or partial control only on medium and fine textured soils.
