NON·LIBERTYLINK COTTON - POST-HARVEST
IMPORTANT CROP SAFETY INFORMATION READ BEFORE USING THIS PRODUCT
Reckon 280SL may be applied as a burndown treatment prior to planting or prior to emergence of any conventional or transgenic variety of canola, corn, sweet corn*, cotton, olive, rice*, soybean or sugar beet. Reckon 280SL may be applied to conventional cotton not tolerant to the active ingredient in Reckon 280SL using a hooded sprayer.
*Not for use in CA
Post emergence row crop applications of Reckon 280SL may be made only to crops tolerant to the active ingredient in this product. Orion GFS, LLC does not warrant the use of this product on crops other than those designated as LibertyLink® to safely withstand the application of Reckon 280SL.
The basis of selectivity of Reckon 280SL in crops is the presence of a gene in LibertyLink crops which results in a plant that is tolerant to the active ingredient in Reckon 280SL. Crops not containing this gene will not be tolerant to Reckon 280SL, and severe crop injury and/or death may occur. Do not allow spray to contact foliage or green tissue of desirable vegetation other than crops tolerant to the active ingredient in this product.
Applications to trees, vines and berries should avoid contact of Reckon 280SL solution, spray, drift or mist with green bark, stems, or foliage, as injury may occur to trees, berries and vines. Only trunks with callused, mature brown bark should be sprayed unless protected from spray contact by nonporous wraps, grow tubes or waxed containers. Contact of Reckon 280SL with parts of trees, berries or vines other than mature brown bark can result in serious damage.
Reckon 280SL is a water-soluble herbicide for application as a foliar spray for the control of a broad spectrum of emerged annual and perennial grass and broadleaf weeds in LibertyLink canola, corn, cotton and soybean, and in trees, vines and berries. Reckon 280SL may also be applied for potato vine desiccation. Reckon 280SL may also be applied as a broadcast burndown application before planting or prior to emergence of any conventional or transgenic variety of canola, corn, sweet corn*, cotton, olive, rice*, soybean or sugar beet.
*Not for use in CA
Reckon 280SL is only foliar-active with little or no activity in soil. Weeds that emerge after application will not be controlled. Apply Reckon 280SL to actively growing weeds as described in the Weed Control Recommendations for Row Crops section to get maximum weed control. Uniform, thorough spray coverage is necessary to achieve consistent weed control. Necrosis of leaves and young shoots occur within 2 to 4 days after application under good growing conditions.
- Reckon 280SL is rainfast four (4) hours after application to most weed species; therefore, rainfall within four (4) hours may necessitate retreatment or may result in reduced weed control.
- Applications should be made between dawn and 2 hours before sunset to avoid the possibility of reduced lambsquarters and velvetleaf control.
Consult your local Cooperative Extension Service or Orion GFS Representative for guidelines on the optimum application timing for Reckon 280SL in your region.
- Weed control may be reduced if application is made when heavy dew, fog and mist/rain are present; or when weeds are under stress due to environmental conditions such as drought, cool temperatures or extended periods of cloudiness.
- To maximize weed control, do not cultivate from 5 days before an application to 7 days after an application.

Integrated Weed Management
The active ingredient in Reckon 280SL is glufosinate-ammonium, which is a glutamine synthetase inhibitor (Group 10). Integrated weed management guidelines promote an economically viable, environmentally sustainable and socially acceptable weed control program regardless of the herbicide(s) used. The highlights of a successful integrated weed management program include:
1. Correctly identify weeds and look for trouble areas within field to identify resistance indicators.
2. Rotate crops.
3. Start the year with clean fields.
4. Rotate herbicide modes of action by using multiple modes of action during the year and apply no more than two applications of a single herbicide mode of action to the same field in a two-year period. One method to accomplish this is to rotate herbicide tolerant trait systems.
5. Apply listed rates of herbicides to actively growing weeds at the correct time with the right application techniques.
6. Control any weeds that may have escaped the herbicide application.
7. Thoroughly clean field equipment between fields.
Contact your local agronomic advisor for more specific information on integrated weed management for your area.
APPLICATION AND MIXING PROCEDURES
Do not use flood jet nozzles, controlled droplet application equipment or air-assisted spray equipment. Uniform thorough spray coverage is important to achieve consistent weed control.
Ground Application: Refer to the Rate Tables for proper application rates. DO NOT apply when winds are gusty or when conditions will favor movement of spray particles off the desired spray target. To avoid drift and insure consistent weed control, apply Reckon 280SL with the spray boom as low as possible while maintaining a uniform spray pattern. Reckon 280SL should be applied broadcast in a minimum of 15 gallons of water per acre using a minimum spray pressure of 40 psi and a maximum ground speed of 10 mph. The use of 80 degree or 110 degree flat fan nozzles is highly recommended for optimum spray coverage and canopy penetration. Application of the spray at a 45-degree angle forward will result in better spray coverage. Under dense weed/crop canopies, 20 to 40 gallons of water per acre should be used so that thorough spray coverage will be obtained. Apply Reckon 280SL using nozzles and pressures that generate MEDIUM (about 250 to 350 microns) spray droplets category as reported by the nozzle manufacturer and in accordance to ASABE S 572. Do not use nozzles and pressures that result in COARSE sprays. FINE sprays should also be avoided to minimize spray drift risk. Boom height should be based on nozzle manufacturer recommendations. See the Spray Drift Management section of this label for additional information on proper application of Reckon 280SL.
Aerial Application: Poor coverage will result in reduced weed control. For optimal weed control, apply Reckon 280SL in a minimum of 10 gallons per acre. Apply Reckon 280SL using nozzles and pressures that generate MEDIUM (about 300 to 400 microns) spray droplets category as reported by the nozzle manufacturer and in accordance to ASABE S 572 based upon the selected air speed. Do not use nozzles and pressures that result in COARSE sprays. FINE sprays should also be avoided to minimize spray drift risk. See the Spray Drift Management section of this label for additional information on proper application of Reckon 280SL.
APPLICATION METHODS TO NON·LIBERTYLINK COTTON
Application of Reckon 280SL to cotton varieties not labeled as LibertyLink requires the use of hooded spray equipment designed to minimize exposure of the spray to the cotton stand. A hooded sprayer directs the spray onto weeds, while shielding the cotton stand from contact. Use nozzles that provide uniform coverage within the treated area. Keep hoods on these sprayers adjusted to protect desirable vegetation. Extreme care must be exercised to avoid exposure of the desirable vegetation to the spray.
With a hooded sprayer, the spray pattern is completely enclosed on the top and all 4 sides by a hood, thereby shielding the crop from the spray solution. This equipment must be set up and operated in a manner that avoids bouncing or raising the hoods off the ground in any way. The spray hoods must be operated on the ground or skimming across the ground. Tractor speed must be adjusted to avoid bouncing of the spray hoods. Avoid operation on rough or sloping ground where the spray hoods might be raised off the ground. If the hoods are raised, spray particles may escape and come into contact with the cotton, causing damage or destruction of the crop.
Herbicide rates and spray volume instructions are presented as broadcast equivalents and must be reduced in proportion to the area actually treated.
Reckon 280SL may be applied as a post-harvest burndown treatment to fields (after cotton harvest). Up to 43 fl oz/A of Reckon 280SL may be applied in a single application to control larger weeds growing in the crop at the time of harvest. If more than 29 fI oz/A is used in a single application, the yearly total may not exceed 72 fl oz/ A, including all application timings. Refer to the Rotational Crop Restrictions section of this label for appropriate rotational crop information.
APPLICATION DIRECTIONS COTTON SEED PROPAGATION
Reckon 280SL may be applied to select out susceptible "segregates," plants that are not tolerant to glufosinate-ammonium during seed propagation.
- Cotton: Reckon 280SL may also be used in cotton seed propagation as a foliar spray to selectively eliminate cotton plants that do not carry a gene that imparts tolerance to glufosinate-ammonium and as such, can be applied to remove susceptible segregates during cotton seed propagation. Breeding material not possessing the glufosinate-ammonium tolerance gene will be severely injured or killed if treated with this herbicide. See Application Use Directions for Use on Cotton for use rates and application timing.
