Rotational Crop Restrictions
This product may persist in the soil past the cotton growing season. To avoid difficulties in establishing rotational crops, follow the restrictions in Table 1 of the label.
- If this product is used for two consecutive years in the same field, only plant cotton, peanut or sweet potato the following year in those fields.
- In the event of poor cotton stand due to adverse weather or other circumstances, a field treated with this product may be replanted with cotton following light tillage or planted in the undisturbed soil. During replanting, minimum tillage is recommended to preserve the herbicide barrier for effective weed control.
- If a field needs to be replanted with cotton due to poor stand or stand failure, do not apply a second application of this product. If tank-mix combinations were initially used, refer to product labels for any additional replanting instruction.
- Follow the crop rotation intervals specified in Table 1. For any crop not specifically listed in Table 1, do not replant for at least 18 months in fields treated with this product, as crop injury may occur.
- Over-application may result in crop injury or injury to rotational crops. Avoid overlapping spray swaths, as injury may occur to rotational crops.
MIXING AND APPLICATION DIRECTIONS
Apply this product evenly and uniformly to the soil surface with a minimum spray solution of 10 gallons per acre. Fill spray tank partially full with water (e.g. ½ full). Start agitation. Add correct quantity of this product. Maintain continuous agitation while filling spray tank to required volume and during application. Do not stop agitation prior to or during application. Nozzle selection should meet manufacturer’s volume and pressure recommendations for preplant surface or preemergence applications. Uniform spray coverage is essential for good efficacy.
Spray Additives and Fertilizers: No adjuvants are needed for application of this product. However, if this product is part of a tank-mix that includes a burndown herbicide or combination, follow label use directions for the adjuvant/surfactant and other herbicides used in the tank-mix. Conduct a jar test before mixing this product with adjuvants and/or fertilizer to ensure compatibility. Generally, tank mix additives should be added last to the tank mix. Do not mix this product with spray adjuvants or drift control agents containing polyacrylamide.
Soil Preparation – Start Weed Free
This product will not control established weeds. It is important to start Weed Free by controlling all existing weeds prior to and/or during this product’s application. Depending on the type of tillage, established weeds could be covered with soil and shielded from exposure to the burndown herbicide. Therefore, for best results, apply burndown herbicides 24 to 96 hours prior to cultivation in conventional and strip tillage systems. Depending on environmental conditions, tillage can also disturb the seed bank and cause more weeds to germinate. Therefore, it is recommended to tank-mix this product with a burndown herbicide, such as Gramoxone (active ingredient paraquat labeled for use in cotton), at the time of planting. It is the pesticide user’s responsibility to ensure that all products in the listed mixtures are registered for the intended use. Users must follow the most restrictive directions for use and precautionary statements of each product in the tank mixture.
Apply this product as a preplant surface or preemergence application. Refer to Table 2 for specific rates by soil type. Use lower rates in areas where weed pressure is low and higher rates in areas where weed pressure is heavy. Application of this product to soils with high clay content may require higher rates. Application of this product to soils with high organic matter (e.g. >3%) may result in reduced efficacy.
This product may be applied as a banded application. When this product is applied on a band, calculate the amount of herbicide and water volume needed for band treatment by the formulas given in the label.
Band width must not exceed 50% (one-half) the cotton row width. Best coverage is obtained with a minimum of two nozzles, one directed to each side of the planted row. Application with a single nozzle directed over the top of the row is suitable for preemergence applications. Cultivation of untreated areas may be needed following band applications.
This product contains a Group 12 herbicide. Any weed population may contain or develop plants naturally resistant to Group 12 herbicides. Combining active ingredients through tanking mixing is one way to delay development of herbicide resistance. However, weed species with acquired resistance to Group 12 may eventually dominate the weed population if Group 12 herbicides are used repeatedly in the same field or in successive years as the primary method of control for targeted species. This may result in partial or total loss of control of those species by this product or other Group 12 herbicides.
Do not apply a product containing fluridone to the same field more than two years in a row. After the second year’s application, use an alternative herbicide from Groups other than 12, effective in controlling the weeds of concern the following year.
To delay herbicide resistance consider:
- Avoiding the consecutive use of this product and other target site of action Group 12 herbicides that have a similar target site of action, on the same weed species;
- Basing herbicide use on a comprehensive Integrated Pest Management (IPM) program;
- Monitoring treated weed populations for loss of field efficacy and treat weed escapes immediately with another group herbicide - start weed free and stay weed free;
- Contacting your local extension specialist, certified crop advisors, and/ or manufacturer for herbicide resistance management and/or integrated weed management recommendations for specific crops and resistant weed biotypes;
- Consulting your agricultural dealer, consultant, applicator, and/or appropriate state agricultural extension service representative for specific alternative cultural practices or herbicide recommendations available in your area.
- Contacting a SePRO Corporation company representative for further information or to report suspected resistance.
Integrated Pest Management
This product may be used as part of an Integrated Pest Management (IPM) program that can include biological, cultural, and genetic practices aimed at preventing economic pest damage. IPM principles and practices include field scouting or other detection methods, correct target pest identification, population monitoring, and treating when target pest populations reach locally determined action thresholds. Consult your state cooperative extension service, professional consultants or other qualified authorities to determine appropriate action treatment threshold levels for treating specific pest/crop systems in your area.
Germinating weeds can be controlled by soil residual activity from either preplant surface or preemergence applications of this product in no till, strip or conventional tillage situations.
Apply this product as a preemergence treatment to coarse, medium or fine textured soils at rates from 16 to 32 fluid ounces per acre. If applying less than 21 fluid ounces per acre, another residual herbicide (such as fomesafen or fluometuron) must be tank mixed with this product. Use in accordance with the most restrictive label limitations and precautions of the products used in the tank-mix. Do not exceed any labeled rate and only tank mix with other herbicides labeled for use in cotton and compatible with the cotton trait being planted. For best results, apply behind the planter (i.e. at planting) or within 36 hours after planting. Do not apply more than 32 fluid ounces per acre. Moisture is necessary to activate this product in soil for residual weed control. Dry weather following applications of this product may reduce effectiveness. For improved weed control, a minimum of 0.5 inches of rain or overhead irrigation is recommended following application.
Preplant Surface Applications
This product may be applied as preplant surface application in coarse, medium or fine textured soils at rates from 16 to 32 fluid ounces per acre up to 14 days before planting. If applying less than 21 fluid ounces per acre, another residual herbicide (such as fomesafen or fluometuron) must be tank mixed with this product. Use in accordance with the most restrictive label limitations and precautions of the products used in the tank-mix. Do not exceed any labeled rate and only tank mix with other herbicides labeled for use in cotton and compatible with the cotton trait being planted. Do not apply more than 32 fluid ounces per acre. Apply after the last tillage operation is completed. A minimum of 0.5 inches of rain or overhead irrigation must occur before planting cotton; cotton must be planted at least 0.75 inches in depth; and the seedbed must not be disturbed or reworked following application.
Controlling Early Weed Escapes
DO NOT use this product as a stand-alone herbicide. This product must be used as part of a comprehensive weed control program. Weeds may escape control prior to this product being activated by moisture. A postemergent application within 18 days after planting that includes glyphosate, glufosinate, or other post-emergent herbicide that is effective at controlling the target weed and compatible with the cotton variety, combined with a residual herbicide (e.g. Warrant or Dual Magnum), IS REQUIRED to control early germinating weeds and to overlap residual herbicides. The purpose of overlapping residual herbicides during postemergent applications is to eliminate all weed escapes for a zero-tolerance approach. Aggressive scouting is recommended and, when necessary, use secondary postemergent applications including a residual herbicide. Depending on the frequency of weed escapes, standard post-directed or layby herbicide applications are also recommended, when necessary, in addition to other cultural practices. Only use herbicides that are compatible with the cotton variety being grown. If uncertain, contact a local extension agent or crop consultant to verify herbicide tolerance for different cotton varieties.
The Brake Preemergence Four-Step System: Start Weed Free. Stay Weed Free.
1. Pre-plant burndown and/or cultivate;
2. Apply this product at planting or within 36 hours of planting with a burndown herbicide;
3. Apply a postemergent herbicide containing glyphosate, glufosinate, or other post-emergent herbicide that is effective at controlling the target weed and compatible with the cotton variety, combined with a residual herbicide within 18 days after planting; and
4. Scout and utilize postemergent and layby applications with overlapping residuals as needed (See specific directions for Roundup Ready varieties below).
Roundup Ready (glyphosate tolerant) Cotton Varieties
When planting varieties of cotton that are tolerant to Roundup (glyphosate), any escape of glyphosate resistant weeds will not be controlled with a postemergent application of glyphosate. Thus, the use of overlapping residual herbicides is required to maintain adequate control of glyphosate resistant weeds in such systems and to minimize the potential for weed seeds to germinate and become established. For best results, follow a comprehensive weed management program with timely applications of overlapping residual herbicides, such as the integrated herbicide program in Table 3. POST 1 – Application containing a glyphosate and a residual herbicide within 18 days after planting. POST 2 – Second postemergence application containing an additional residual herbicide within 18 days after the POST 1 application. LAYBY – Application containing a residual herbicide within 18 days after the POST 2 application. Additional applications may be necessary depending on environmental conditions and weed pressure. The timely application of overlapping residuals in the post-emergent program is critical for a zero-tolerance weed strategy in Roundup Ready systems and to reduce the chances of glyphosate resistant weeds from becoming established. In areas of high weed pressure and under conditions that favor weed emergence, apply postemergent herbicides following a shorter interval (e.g. 12 days).
- If applying less than 21 fluid ounces per acre, another residual herbicide (such as fomesafen or fluometuron) must be tank mixed with this product. Use in accordance with the most restrictive label limitations and precautions of the products used in the tank-mix. Do not exceed any labeled rate. Due to the many herbicide formulations available and to ensure compatibility, always conduct a jar test before field application of any tank-mix combination.
