WHEAT (INCLUDING DURUM) - ANNUAL AND PERENNIAL BROADLEAF WEEDS
Use CleanWave herbicide for selective control of annual and perennial broadleaf weeds in wheat (including durum) that is rotated with canola, corn, fallow, flax, grain sorghum, grasses, or mustard.
Not for use on wheat underseeded with a legume.
Use Precautions and Restrictions
- Do not apply CleanWave directly to, or allow spray drift to come in contact with, broadleaf crops or other broadleaf plants, including, but not limited to, alfalfa, canola, beans, cotton, flowers, grapes, lettuce, lentils, mustard, peas, potatoes, radishes, soybeans, sugarbeets, sunflowers, tobacco, tomatoes, vegetables, or other desirable broadleaf crops or ornamental plants or soil where sensitive crops will be planted the same season.
- In South Dakota, use of CleanWave is limited to counties west of the Missouri River.
- Avoid application where proximity of crops or other desirable plants is likely to result in exposure to spray or spray drift.
- Use directions in Dow AgroSciences supplemental labeling for CleanWave may supersede directions or limitations in the labeling.
- Do not contaminate irrigation ditches or water used for domestic purposes.
- To avoid crop injury, do not apply to fields with saturated soils.
- Maximum Application Rate: The total amount of CleanWave applied broadcast or as a spot treatment per year, must not exceed 14 fl oz per acre per growing season.
- Chemigation: Do not apply this product through any type of irrigation system.
- Do not transfer livestock following consumption of treated straw to sensitive broadleaf crop areas without first allowing 3 days consumption of feeding of untreated forage. If livestock are transferred within less than 3 days of eating untreated forage, urine and manure may contain enough aminopyralid to cause injury to sensitive broadleaf plants.
This product may be applied in tank mix combination with labeled rates of other products provided (1) the tank mix product is labeled for the timing and method of application for the use site to be treated; and (2) tank mixing with products containing fluroxypyr or aminopyralid is not prohibited by the label of the tank mix product. Use as directed in the Directions for Use section of the tank mix partner. When tank mixing with 2,4-D, users should make certain that the crop has reached the minimum growth stage for application (4-leaf with 3-4 tillers). Applications of 2,4-D made prior to the 4-leaf, tillering stage of growth can result in crop injury.
Apply to actively growing weeds. Extreme growing conditions such as drought or near freezing temperatures prior to, at, or following application may reduce weed control and increase the risk of crop injury at all stages of growth. Only weeds that have emerged at the time of application will be controlled. If foliage is wet at the time of application, control may be decreased. Applications of CleanWave are rainfast within 1 hour after application.
Generally, application rates at the lower end of the specified rate range will be satisfactory for young, succulent growth of weed species and biotypes of kochia resistant to ALS herbicides. For less sensitive species, perennials, biotypes of kochia tolerant to dicamba herbicides, and under conditions where control is more difficult (plant stress conditions such as drought or extreme temperatures, dense weed stands and/or larger weeds), the higher rates within the rate range will be needed.
Use sufficient spray volume to provide thorough coverage and a uniform spray pattern. Do not broadcast apply in less than 3 gallons of total spray volume per acre. For best results and to minimize spray drift, apply in a spray volume of 10 gallons or more per acre. As vegetative canopy and weed density increase, spray volume should be increased to obtain equivalent weed control. Use only nozzle types and spray equipment designed for herbicide application. To reduce spray drift, follow precautions under Avoiding Injury to Non-Target Plants on the label.
To prevent misapplication, apply spot treatments only with a calibrated boom or with hand sprayers according to directions provided:
Hand-Held Sprayers: Hand-held sprayers may be used for spot applications. Care should be taken to apply the spray uniformly and at a rate equivalent to a broadcast application. Application rates in the table on the label are based on an area of 1000 sq ft. Mix the amount of CleanWave (fl oz or ml) corresponding to the desired broadcast rate in 1 gallon or more of spray. To calculate the amount of CleanWave required for larger areas, multiply the table value (fl oz or ml) by the area to be treated in “thousands” of square feet, e.g., if the area to be treated is 3500 sq ft, multiply the table value by 3.5 (calc. 3500 ÷ 1000 = 3.5). An area of 1000 sq ft is approximately 10.5 x 10.5 yards (strides) in size.
Broadleaf Weeds Controlled or Suppressed
Broadleaf Weed Control and Management Practices
Management of Kochia Biotypes: Research has demonstrated that many biotypes of kochia can occur within a single field. While kochia biotypes can vary in their susceptibility to CleanWave, all known biotypes will be suppressed or controlled by the 14 fl oz per acre labeled rate. Application of CleanWave at rates below the 14 fl oz per acre rate can result in a shift to more tolerant biotypes within a field.
Best Resistance Management Practices: Extensive populations of dicamba tolerant kochia have been identified in certain small grain, fallow, and corn production regions (such as Chouteau, Fergus, Liberty, Toole, and Treasure counties in the state of Montana). Apply CleanWave at a rate of 14 fl oz per acre for the control of dicamba tolerant Kochia biotypes. In addition, use of CleanWave should be rotated with products that do not contain dicamba to minimize selection pressure. Use of these practices will preserve the utility of CleanWave for control of dicamba tolerant kochia biotypes. Unless specified by Dow AgroSciences, do not use less than 14 fl oz of CleanWave per acre for control of known dicamba tolerant biotypes of kochia.
Weeds Suppressed: Weed suppression is expressed as a reduction in weed competition (reduction population or vigor) as compared to an untreated area. The degree of weed control and duration of effect may vary with weed size, density, application rate, coverage, and growing conditions before, during and after treatment.
Effect on Perennial Weeds: CleanWave will suppress the initial top growth and inhibit regrowth during the season of application. At higher use rates shown on the label, CleanWave may cause a reduction in shoot regrowth in the season following application; however, plant response may be inconsistent due to inherent variability in shoot regrowth from perennial root systems.
Refer in the supplemental label For Control Of Annual And Perennial Broadleaf Weeds In Wheat (Including Durum) For Use Only in Montana.
WHEAT (INCLUDING DURUM)
Application Timing: Apply as a broadcast postemergence spray to actively growing wheat from the 3 leaf growth stage up to early jointing stage (Zadoks 30) for control of listed broadleaf weeds. Apply when weeds are actively growing and at specified growth stages. For best activity on perennial weeds such as Canada thistle, apply when the majority of the basal leaves have emerged from the soil up to bud stage. Only weeds that have emerged at the time of application will be controlled.
Application may be timed to control later-emerging weeds when wheat is between early joint and second node stage (Zadoks 32); however, do not apply unless the risk of injury is acceptable. Factors which can influence crop tolerance at later application stages include inaccurate determination of crop growth stage, tank mix partners or environmental factors. Do not apply after the second node stage.
Extreme growing conditions such as drought or near freezing temperatures prior to, at, and following time of application may reduce weed control and increase the risk of crop injury at all stages of growth. Do not use this product if the cereal crop is underseeded with a legume.
Spot Application: Spot applications may be made; however, to prevent over-application spot treatments should be applied at rates and spray volumes equivalent to broadcast application. See instructions for Spot Treatments in Application Directions section.
- Do not tank mix CleanWave with Osprey or Osprey+MCPA
- There are no restrictions on grazing following application of CleanWave at labeled rates.
- Preharvest Interval: Do not apply within 14 days of harvest for hay or within 50 days of harvest for grain and straw.
WEEDS CONTROLLED AND SUPPRESSED:
For best control or suppression, apply up to the 2 to 4 leaf stage of growth of the following weeds:
Cocklebur common, Lambsquarter common, Marshelder, Nightshade (black, cutleaf, Eastern black, hairy), Ragweed common, Ragweed, giant, Sunflower, Buffalobur, Ladysthumb and Smartweed, green.
Bedstraw: For best control, apply in the 1 to 4 whorl stage of growth.
Buckwheat, wild: For best control, apply in the 1 to 3 leaf stage of growth, before vining.
Kochia: Includes herbicide tolerant or resistant biotypes up to 8 inches tall. Best control is achieved when weeds are at least 1 inch tall. Refer to Broadcast Application Rates table for additional information.
Sowthistle, perennial, Thistle, Canada: For best control or suppression, apply from rosette to bud (preflower) stage of growth.
