TREE NUTS, VINES, AND TREE FRUITS - WEEDS GREATER THAN 6 INCHES IN HEIGHT AND/OR GRASSES THAT HAVE TILLERED
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.
ROTATIONAL CROP RESTRICTIONS*
Rotational crop planting intervals following application of Reckon 280SL are listed below. Failure to comply with these restrictions may result in illegal residues in rotated crops.
Plant Back Interval (Minimum Rotational Crop Planting Interval from Last Application)
Canola, Corn, Sweet Corn, Cotton, Rice, Soybean and Sugar Beet: May be planted at any time
Root and Tuber Vegetables, Leafy Vegetables, Brassica Leafy Vegetables and Small Grains (barley, buckwheat, oats, rye, teosinte, triticale, and wheat): 70 Days
All Other Crops: 180 Days
*See Application Directions for Potato Vine Desiccation for Rotational Crop Restrictions specifically after Reckon 280SL applications to potatoes.
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 DIRECTIONS FOR USE ON LISTED TREE, VINE, AND BERRY CROPS
Apply Reckon 280SL to the tree, vine, and berry crops listed below. Uniform, thorough spray coverage is necessary to achieve consistent weed control.
- Citrus: lemon, orange, grapefruit, lime, mandarin, tangerine, tangelo, calamondin, kumquat, pummelo, citron and tangor; cultivars, varieties and/or hybrids of these
- Pome Fruits: apples, pears, crabapple, loquat, mayhaw, quince, azarole, medlar and tejocote; cultivars, varieties and/or hybrids of these

APPLICATION RATE AND TIMING
For best results, apply to emerged, young, actively growing weeds. Warm temperatures, high humidity, and bright sunlight improve the performance of Reckon 280SL. Refer to the Weed Control for Row Crops section of this label for selection of the proper rate dependent upon weed species present and size. Weeds under stress or in dense populations will require application at the highest specified label use rate. Stressed conditions also include prior treatments of other contact or systemic herbicides. Do not retreat these weeds with Reckon 280SL until sufficient regrowth has occurred.
Apply Reckon 280SL as a directed spray to control undesirable vegetation in tree, vine and berries listed on this label. Apply as a broadcast, banded, or spot treatment application depending on the situation to control weeds listed under the heading “Weeds Controlled in Tree, Vine and Berry crops”. Avoid direct spray or drift to desirable vegetation. Regrowth may occur due to the weed stage of growth at application, low use rate, or environmental conditions. Repeat applications of Reckon 280SL may be necessary to control plants generating from underground parts or seed.
Avoid contact of Reckon 280SL solution, spray, drift or mist with green bark, stems, or foliage, as injury may occur to trees 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 or vines other than mature brown bark can result in serious damage.
Application Methods for Broadcast Applications
Apply Reckon 280SL at the rates listed below for broadcast applications based on weed size and stage of growth.
Application Methods for Banded Spray Applications
Banded applications may be used using formula given in the label to calculate the amount of herbicide needed for orchard or vineyard strip sprays
