SORGHUM (GRAIN) - MEDIUM OR FINE TEXTURED SOIL - 3% OR MORE ORGANIC MATTER - PREPLANT SURFACE APPLICATION
Sortie ATZ Lite herbicide is a selective preemergence herbicide for controlling most annual grasses, many annual broadleaf weeds, and sedges in field corn, seed corn, sweet corn, popcorn and grain sorghum.
Some weed species may have triazine-resistant biotypes that will not be controlled adequately by this product. If resistant biotypes are suspected, use an alternate program, or use non-triazine products such as Clarity or Prowl herbicide in combination with Sortie Lite or use Distinct sequentially.
Sortie ATZ Lite may be applied preplant surface, preplant incorporated, preemergence or early postemergence to corn or sorghum. Sortie ATZ Lite will provide most effective weed control when applied (by ground or aerial equipment), and subsequently incorporated into soil by rainfall, sprinkler irrigation, or mechanical tillage prior to weed seedling emergence from soil. Sortie ATZ Lite may be applied using either water or fluid fertilizer as the spray carrier, or impregnated onto and applied with dry bulk fertilizer. Sprayable fluid fertilizer as a carrier is not recommended for use after crop emergence unless the typical fertilizer burn symptoms on the crop are acceptable. Refer to Additives section for more information.
Use rates of this product vary by soil texture and organic matter.
When use rates are expressed in ranges, use the lower rates for more coarsely textured soils lower in organic matter and use the higher rates for more finely textured soils that are higher in organic matter. Reduced rates may be used where partial control or reduced length of soil residual control is required.
Aerial Application Methods and Equipment
Water Volume: Use 2 or more gallons of water per acre. The actual minimum spray volume per acre is determined by the spray equipment used. Adequate spray volume must be used to provide accurate and uniform distribution of spray particles over the treated area and to avoid drift of spray particles to nontarget areas.
Ground Application (Banding)
When applying Sortie ATZ Lite herbicide by banding, determine the amount of herbicide and water volume needed using the given formula in the label.
Ground Application Methods and Equipment (Broadcast)
Water Volume: Use 5 or more gallons of water per acre. The actual minimum spray volume per acre is determined by the spray equipment used. Adequate spray volume must be used to provide accurate and uniform distribution of spray particles over the treated area and to avoid drift of spray particles to nontarget areas.
RESTRICTIONS AND LIMITATIONS
- Restricted Use Pesticide: This product is a restricted use herbicide due to ground and surface water concerns. Users must read and follow all precautionary statements and instructions for use in order to minimize potential for atrazine to reach ground and surface water.
- DO NOT apply through any type of irrigation system. DO NOT contaminate irrigation ditches or water used for domestic purposes.
- Maximum seasonal use rate: DO NOT apply more than a total of 3.5 pints of Sortie ATZ Lite herbicide per acre, per season. Sortie ATZ Lite contains 2.75 pounds of the active ingredient atrazine per gallon (0.34 pounds of ai per pint). When tank mixing or sequentially applying atrazine or products containing atrazine to corn or sorghum, the total pounds of atrazine applied (lbs ai/A) must not exceed the specific seasonal rate limits from preemergence, or postemergence, or preemergence + postemergence sequential applications, as noted below:
Prior to crop emergence: DO NOT exceed 1.6 pounds of atrazine ai per acre on highly erodible soils (as defined by Natural Resource Conservation Service) with less than 30% plant residue cover. DO NOT exceed 2.0 pounds of atrazine ai per acre on other soils.
After crop emergence: DO NOT exceed 2.0 pounds of atrazine ai per acre on any soil.
Prior to and after crop emergence (sequential applications): DO NOT exceed a total of 2.5 pounds of atrazine ai per acre on any soil per year.
The total pounds of atrazine applied from all sources must not exceed 2.5 pounds of active ingredient per acre per year.
- Sortie ATZ Lite is not for sale, distribution, or use in Nassau or Suffolk counties in New York state.
- Crop Rotation Restriction:
If the crop treated with Sortie ATZ Lite is lost to adverse weather or for other reasons, the area treated may be replanted to corn and grain sorghum immediately. If the original Sortie ATZ Lite treatment was broadcast, DO NOT make a second application of Sortie ATZ Lite if the combined rate exceeds the maximum rate per season. If the original application was banded and the second crop is planted in the row middles, a second band application may be applied.
Corn, sorghum, soybeans, cotton or peanuts may be planted the year following treatment. Injury may occur to soybeans planted on soils having a 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 application, or injury may occur.
Stress: DO NOT apply to crops under stress such as stress due to lack of moisture, hail damage, flooding, herbicide injury, mechanical injury, or widely fluctuating temperatures, as injury may result.
See label for the tank mix information/directions.
Sortie ATZ Lite may be applied preplant, preplant incorporated, preemergence or postemergence to grain sorghum up to 12 tall.
All Sortie ATZ Lite applications must only be made to sorghum seed that has been properly treated by the seed company with an approved chloroacetamide herbicide safener or severe injury may occur.
DO NOT use Sortie ATZ Lite on sorghum planted in coarse- textured soil.
For best performance, make preemergence surface applications within 5 days of the last preplant tillage. Under high soil moisture or cool conditions, Sortie ATZ Lite application may cause temporary stunting or leaf wrapping of sorghum. Sorghum will normally outgrow these symptoms in 10-14 days.
Sortie ATZ Lite is not registered for use on sweet or forage sorghum.
Sorghum forage may be grazed or fed to livestock 60 days or more after preemergence application of Sortie ATZ Lite.
Sorghum forage may be grazed or fed to livestock 45 days or more after postemergence application of Sortie ATZ Lite. Grain and fodder may be harvested and fed 80 days or more after application of Sortie ATZ Lite.
Preplant Surface Applications: For use in minimum tillage or no-tillage production systems, apply Sortie ATZ Lite alone or in tank mixes up to 45 days before planting. When making early preplant applications (15-45 days prior to planting), use 3.5 pints of Sortie ATZ Lite on all soil types. Early preplant applications are not recommended for use on coarse-textured soils or in areas where average annual rainfall (or rainfall + irrigation) typically exceeds 40. Early preplant applications may be applied as part of a split application program where the second application is made after planting (use 2/3 of Sortie ATZ Lite rate early followed by 1/3 of rate after planting). A split application is recommended when the initial application is made more than 30 days prior to planting. Tank mixes with post- emergence herbicides such as Clarity, glyphosate, Gramoxone Extra, or Touchdown must be used when weeds are more than 1.5 tall at the time of application.
Split Applications: Sortie ATZ Lite may be used in split application programs where applications are made as part of the methods described in the label. If applications are less than 2 weeks apart, the total Sortie ATZ Lite rate used must not exceed the maximum rate given for each specific soil type. If applications are 2 weeks or more apart, a total Sortie ATZ Lite use rate of up to 3.5 pints per acre per year may be used on any soil type.
NOTE: To assist in determining product use rates of Sortie ATZ Lite when it is important to manage application rates of atrazine active ingredient (ai), refer to the following quick calculation guide:
- 2.0 pints of Sortie ATZ Lite delivers 0.7 lbs ai/A of atrazine
- 2.5 pints of Sortie ATZ Lite delivers 0.85 lbs ai/A of atrazine
- 3.0 pints of Sortie ATZ Lite delivers 1.0 lbs ai/A of atrazine
- 3.5 pints of Sortie ATZ Lite delivers 1.2 lbs ai/A of atrazine
For all early preplant applications, use 3.5 pints of Sortie ATZ Lite per acre.
On all soils with 8-20% organic matter, use 3.5 pints of Sortie ATZ Lite per acre. Sortie ATZ Lite is not recommended for use on soils with more than 20% organic matter.
