WHEAT, BARLEY AND TRITICALE - WEEDS CONTROLLED LIGHT INFESTATION
DuPont AGILITY SG must be used only in accordance with instructions on this label or in supplemental DuPont publications.
DuPont will not be responsible for losses or damages resulting from the use of this product in any manner not specified by DuPont.
AGILITY SG is for use on wheat, barley, triticale and fallow in most states, check with your state extension service or Department of Agriculture before use, to be certain AGILITY SG is registered in your state. AGILITY SG is not registered for use in Alamosa, Conejos, Costilla, Rio Grande, and Saquache counties of Colorado unless use is directed otherwise by supplemental labeling.
AGILITY SG herbicide is a water soluble granule that is used for selective postemergence weed control in wheat (including durum), barley, triticale and fallow.
The best control is obtained when AGILITY SG is applied to young, actively growing weeds. The degree and duration of control may depend on the following:
- weed spectrum and infestation intensity
- weed size at application
- environmental conditions at and following treatment
AGILITY SG is noncorrosive, nonflammable, and does not freeze. AGILITY SG should be mixed and completely dissolved in water and applied as a uniform broadcast spray (See Tank Mixtures and Mixing Instructions sections for use with Liquid Nitrogen Fertilizer Solutions).
- Do not use AGILITY SG plus Malathion or Lorsban as crop injury may result.
- Do not harvest sooner than 45 days after the last application of AGILITY SG.
- AGILITY SG is only registered on wheat, barley, triticale and fallow. Do not use on any other crop.
- Do not apply to wheat, barley or triticale undersown with legumes and grasses, because injury to the forages will result.
- Do not treat irrigation ditches or water used for crop irrigation or domestic uses.
- Do not apply this product through any type of irrigation system.
- Varieties of wheat (including durum), barley and triticale may differ in their response to various herbicides. DuPont recommends that you first consult your state experiment station, university, or extension agent as to sensitivity to any herbicide. If no information is available, limit the initial use of DuPontAGILITY SG to a small area.
- Under certain conditions such as heavy rainfall, prolonged cold weather, or wide fluctuations in day/night temperatures prior to or soon after AGILITY SG application, temporary discoloration and/or crop injury may occur. To reduce the potential of crop injury, tank mix AGILITY SG with 2,4-D and apply after the crop is in the tillering stage of growth.
- Application to wheat, barley or triticale that is stressed by severe weather conditions, drought, low fertility, water-saturated soil, disease, or insect damage, may result in crop injury. Risk of injury is greatest when crop is in the 2 to 5- leaf stage. Severe winter stress, drought, disease, or insect damage following application also may result in crop injury.
- For ground applications applied when dry, dusty field conditions exist, control of weeds in wheel track areas may be reduced. The addition of 2,4-D or MCPA may improve weed control under these conditions.
- Injury to or loss of desirable trees or vegetation may result from failure to observe the following:
- Do not apply, drain or flush equipment on or near desirable trees or other plants or on areas where their roots may extend, or in locations where the chemical may be washed or moved into contact with their roots.
- Do not use on lawns, walks, driveways, tennis courts, or similar areas. Prevent drift of spray to desirable plants.
Sensitive Crop Precautions
AGILITY SG may cause injury to desirable trees and plants, particularly beans, cotton, flowers, fruit trees, grapes, ornamentals, peas, potatoes, soybeans, sunflowers, tobacco, tomatoes, and other broadleaf plants when contacting their roots, stems, or foliage.
These plants are most sensitive to AGILITY SG during their development or growing stage.
Directions to avoid herbicide drift near sensitive crops:
- Do not make applications when spray particles may be carried by air currents to areas where sensitive crops and plants are growing.
DO NOT spray near sensitive plants if wind is gusty or in excess of 5 mph and moving in the direction of adjacent sensitive crops. Leave an adequate buffer zone between area to be treated and only sensitive plants. Coarse sprays are less likely to drift out of the target area than fine sprays.
- Use coarse sprays (volume median diameter of 400 microns or more) to avoid potential herbicide drift. Select nozzles that are designed to produce minimal amounts of fine spray particles (less than 200 microns). Examples of nozzles designed to produce coarse sprays via ground applications are Delavan Raindrops, Spraying Systems XR (excluding 110° tips) flat fans, Turbo Teejets, Turbo Floodjets, or large capacity flood nozzles such as D10, TK10, or greater capacity tips.
- Keep the spray pressure at or below 20 psi and the spray volume at or above 20 gallons per acre (for ground broadcast applications), unless otherwise required by the manufacturer of drift-reducing nozzles. Consult your spray nozzle supplier concerning the choice of drift-reducing nozzles.
- DO NOT apply AGILITY SG adjacent to sensitive crops when the temperature on the day of application is expected to exceed 85° F as drift is more likely to occur.
- Agriculturally approved drift-reducing additives may be used.
- Carefully observe all sprayer cleanup instructions both prior to and after using this product, as spray tank residue may damage crops other than wheat, barley or triticale.
ENVIRONMENTAL CONDITIONS AND BIOLOGICAL ACTIVITY
AGILITY SG is absorbed through the roots, shoots, and foliage of plants, rapidly inhibiting the growth of susceptible weeds. One to three weeks after postemergence application to weeds (2 to 5 weeks for wild garlic), susceptible plants are controlled. In warm, moist conditions, the expression of herbicide symptoms is accelerated; in cold, dry conditions, expression of herbicide symptoms is delayed.
AGILITY SG will provide up to 4 to 6 weeks of residual weed control. Susceptible weeds may germinate and emerge a few days after postemergence applications, but growth then ceases and leaves become chlorotic 3- 5 days after emergence. Death of leaf tissue and growing point will follow in some species, while others may remain green but stunted and noncompetitive.
AGILITY SG provides the best control of weeds in vigorously growing crops that shade competitive weeds. Weed control in areas of thin crop stand or seeding skips may not provide satisfactory control. However, a crop canopy that is too dense at application can intercept spray and reduce weed control.
The herbicidal action of AGILITY SG may be less effective on weeds stressed from adverse environmental conditions (such as extreme temperatures or moisture), abnormal soil conditions, or cultural practices. In addition, weeds hardened-off by drought stress are less susceptible to AGILITY SG.
AGILITY SG, which contains the active ingredients thifensulfuron methyl, tribenuron methyl, metsulfuron methyl and dicamba, is both a Group 2 and a Group 4 herbicide based on the mode of action classification system of the Weed Science Society of America.
When herbicides with mode of action classifications that affect the same biological sites of action are used repeatedly over several years to control the same weed species in the same treatment area, naturally-occurring resistant biotypes may survive a correctly applied herbicide treatment, propagate, and become dominant in that area. Adequate control of these resistant weed biotypes cannot be expected. If weed control is unsatisfactory, it may be necessary to retreat the problem area using a product affecting a different biological site of action. To better manage herbicide resistance through delaying the proliferation and possible dominance of herbicide resistant weed biotypes, it may be necessary to change cultural practices within and between crop seasons such as using a combination of tillage, retreatment, tank-mix partners and/or sequential herbicide applications that affect a different site of action. Weed escapes that are allowed to go to seed, and movement of plant material between treatment areas on equipment will promote the spread of resistant biotypes. It is advisable to keep accurate records of pesticides applied to individual fields to help obtain information on the spread and dispersal of resistant biotypes. Consult your agricultural dealer, consultant, applicator, and/or appropriate state agricultural extension service representative to determine appropriate actions for treating specific resistant weed biotypes in your area.
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.
Application and Spray Volumes
Ground or aerial application equipment which will give good spray coverage of weed foliage should be used. HOWEVER, DO NOT USE AERIAL APPLICATION EQUIPMENT IF SPRAY PARTICLES CAN BE CARRIED BY WIND INTO AREAS WHERE SENSITIVE CROPS OR PLANTS ARE GROWING.
Apply 3 to 50 gallons of diluted spray per treated acre when using ground application equipment, or 2 to 10 gallons of diluted spray per treated acre when using aerial application equipment. Use the higher level of the listed spray volumes when treating dense or tall vegetation. Use coarse sprays.
Select nozzles designed to produce minimal amounts of fine spray particles. Spray with nozzles as close to the weeds as is practical for good weed coverage.
AGILITY SG should not be applied during periods of gusty wind or when wind is in excess of 15 mph as uneven spray coverage may occur.
Avoid disturbing (e.g. cultivating or mowing) treated areas for at least 7 days following application.
For optimum spray distribution and thorough coverage, use flat-fan or low-volume flood nozzles.
For flat-fan nozzles, use a spray volume of at least 5 gal per acre (GPA).
For flood nozzles on 30" spacing, use flood nozzles no larger than TK10 (or the equivalent), a pressure of at least 30 psi and a spray volume of at least 10 GPA only. For 40" nozzle spacing, use at least 13 GPA; for 60" spacing use at least 20 GPA. It is essential to overlap the nozzles 100% for all spacings.
"Raindrop RA" nozzles are not recommended for AGILITY SG applications, because weed control performance may be reduced.
Use screens that are 50-mesh or larger.
Use nozzle types and arrangements that provide optimum spray distribution and maximum coverage at 1 to 5 GPA. Use at least 3 GPA in Idaho, Oregon, Washington, or Utah.
When applying AGILITY SG by air in areas near sensitive crops, use solid-stream nozzles oriented straight back. Adjust swath to avoid spray drift damage to downwind sensitive crops and/or use ground equipment to treat border edge of field. See the Spray Drift Management section of this label.
For aerial application in Washington, follow the directions in the Spray Drift Management Section of this label and the following Washington state restrictions:
Applications of DuPont AGILITY SG must be made in equipment that meets the most restrictive Washington Agricultural Codes (WAC) for the prevention of herbicide drift for the respective county.
Do not apply in equipment that does not meet these WAC standards.
AGILITY SG can be applied either before or after applications of other products registered for use in wheat, barley, triticale or fallow. Read and follow all label instructions on timing, precautions, and warnings for these herbicides before using these in sequence with AGILITY SG. If those instructions conflict with this label, do not use that product in sequence with AGILITY SG. It is the pesticide user’s responsibility to ensure that all products are registered for the intended use. Read and follow the applicable restrictions and limitations and directions for use on all product labels involved in tank mixing. Users must follow the most restrictive directions for use and precautionary statements of each product in the tank mixture.
- DuPont ALLY, ALLY EXTRA, and other products containing metsulfuron methyl should not be used as a sequential treatment with AGILITY SG.
- If using DuPont HARMONY EXTRA as a sequential treatment with AGILITY SG, do not exceed 0.7 ounce of HARMONY EXTRA per acre per crop season.
- If using DuPont EXPRESS as a sequential treatment with AGILITY SG, do not exceed 0.25 ounce of EXPRESS per acre per crop season.
- If using products that contain dicamba as a sequential treatment with AGILITY SG, do not exceed the following amounts of acid equivalent dicamba per acre per season: 8.4 ounces in wheat, 5.6 ounces in barley, 2.1 ounces in triticale, and 16.8 ounces in fallow.
Do not exceed 2.0 pounds acid equivalent dicamba per acre per year.
A field bioassay is necessary if crops other than wheat, barley or those listed on this label are to be planted on land previously treated with AGILITY SG. To conduct a field bioassay, grow test strips of the crop or crops you plan to grow the following year in fields previously treated with AGILITY SG. Crop response to the bioassay will indicate whether or not to rotate to the crop(s) grown in the test strips.
If a field bioassay is planned, check with your local DuPont representative for information detailing field bioassay procedure.
Do not graze treated forage within 7 days after application. Do not feed forage from treated areas to livestock within 7 days after application. Do not feed hay from treated areas to livestock within 30 days of application. Harvested straw may be used for bedding and/or feed. Do not harvest grain within 45 days after application.
WHEAT, BARLEY AND TRITICALE
Apply AGILITY SG at the rate of 1.6 to 3.2 ounces per acre to wheat, barley and triticale. See SPRAY ADJUVANTS for proper adjuvant rates.
Use 1.6 to 2.4 ounces per acre of AGILITY SG for light infestation of the weeds listed under Weeds Controlled. Conditions at application should be optimum for effective treatment of these weeds.
Note: See Tank Mix Section for additional info on required combinations when used at less than 3.2 ounces per acre.
Fall-seeded Wheat, Barley, and Triticale
Make applications after the crop is in the 2-leaf stage but before the jointing stage.
Make applications after the crop is in the 2-leaf stage but before it exceeds the 6-leaf stage. Early developing wheat varieties (such as TAM 107, Madison, or Wakefield) must receive application between early tillering and the jointing stage (stagger planting dates with these varieties to be certain that the applications occur before jointing). Durum and Wampum variety must receive application after tillering but before it exceeds the 6-leaf stage and should be made in combination with 2,4-D. See Tank Mix Section for additional information.
Make applications after the crop is in the 2-leaf stage but before it exceeds the 4-leaf stage.
Do not tank mix AGILITY SG with 2,4-D in early season applications on spring-seeded barley.
Make applications after the crop is in the 2-leaf stage but before it exceeds the 6-leaf stage.
Additional Timing Information
Weed control may be reduced if rainfall or snowfall occurs soon after application. Six hours of dry weather are needed to allow AGILITY SG to be sufficiently absorbed by weed foliage.
If applied to irrigated wheat, barley or triticale the first post-treatment irrigation should be delayed for at least 6 hours after treatment and should not exceed 1 inch of water.
Applications of DuPont AGILITY SG to stressed crops may cause crop injury. To reduce the potential of crop injury, tank mix AGILITY SG with 2,4-D (ester formulations perform best-see TANK MIXTURES for more information) and apply after the crop is in the tillering stage of growth.
