EARLY SEEDED WINTER WHEAT
REPORT must be used only in accordance with recommendations on the label or in separate published Cheminova recommendations. Cheminova will not be responsible for losses or damages resulting from the use of this product in any manner not specifically recommended by Cheminova.
Do not apply this product through any type of irrigation system.
REPORT herbicide is recommended for use on land primarily dedicated to the long-term production of wheat, barley, or oat.
APPLICATION TO CEREALS
REPORT is a dry-flowable granule that controls weeds in wheat (including durum), triticale, barley, and spring oat.
In addition, REPORT may also be used on winter oat in Texas, Western Oregon, and Western Washington. REPORT is mixed in water or directly into liquid nitrogen fertilizer solutions and applied as a uniform broadcast spray. A surfactant should be used in the spray mix unless otherwise specified on the label.
Note: For definitions of portions of States recommended on the label, see listings of counties or area definitions on Crop Rotation Interval charts of the label.
REPORT is noncorrosive, nonflammable, nonvolatile, and does not freeze.
REPORT controls weeds by both preemergence and postemergence activity. For best preemergence results, apply REPORT before weed seeds germinate. Use sprinkler irrigation or allow rainfall to move REPORT 2 to 3” deep into the soil profile.
For best postemergence results, apply REPORT to young, actively-growing weeds. The use rate depends upon the weed spectrum and size of weeds at time of application.
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.
Environmental Conditions and Biological Activity
REPORT is absorbed through the roots and foliage of broadleaf weeds, rapidly inhibiting their growth. One to 3 weeks after application to weeds, leaves of susceptible plants appear chlorotic, and the growing point subsequently dies. Postemergent application of REPORT provides the best control in vigorously-growing crops that shade competitive weeds. Weed control in areas of thin crop stand or seeding skips may not be as satisfactory. However, a crop canopy that is too dense at application can intercept spray and reduce weed control. REPORT may injure crops that are stressed from adverse environmental conditions (such as extreme temperatures or moisture), abnormal soil conditions, or cultural practices. In addition, different varieties of the crop may be sensitive to treatment with REPORT under otherwise normal conditions. Treatment of such varieties may injure crops.
In warm, moist conditions, the expression of herbicide symptoms is accelerated in weeds; in cold, dry conditions, expression of herbicide symptoms is delayed. In addition, weeds hardenedoff by drought stress are less susceptible to REPORT.
Rainfall is needed to move REPORT into the soil for preemergence weed control, but postemergence weed control may be reduced if rainfall occurs soon after application.
Preplant Incorporation (PPI) and Preplant Surface (PPS) Applications to Early Seeded Winter Wheat
NOTE: Preplant incorporation and preplant surface treatments are only recommended for early seeded winter wheat where growing conditions are favorable (good soil moisture, moderate temperatures) for good stand establishment prior to winter dormancy.
Apply REPORT as a uniform broadcast spray not more than 3 weeks prior to the anticipated planting of early seeded winter wheat.
Winter wheat may be planted anytime after treatment.
INCORPORATION (PPI)—Follow spray application with shallow (not deeper than 3 to 4’) mechanical incorporation. Use either single pass or double pass incorporation (second pass at right angle to first pass) with sweeps (duckfoot cultivator), spring tooth or field cultivator. Incorporation may be improved if a harrow is pulled behind the primary incorporation implement.
SEEDING AFTER EITHER PPI OR PPS TREATMENT—The use of disc type drills is recommended because of minimal soil disturbance. A hoe type drill may be used if drill spacing is not more than 10” wide and tractor speed is at least 5 mph. if a hoe drill is used, weed control results may be variable depending on amount of soil displacement in seed row. Where practical, a harrow pulled behind a hoe drill should increase the effectiveness of this treatment.
Because of variations in incorporation equipment and seeding techniques, it is recommended that growers limit first use of either PPI or PPS to a small area to be sure weed control results are satisfactory.
Excessive displacement of treated soil may result in poor weed control in the seed row.
Do not apply prior to late fall plantings as cold/dry weather can delay seedling emergence and reduce seedling vigor, making crop more vulnerable to the combination of herbicide and weather stress, resulting in crop injury.
Do not make a preplant incorporated or preplant surface application prior to planting barley or spring oats. In high rainfall situations or on low pH soils (pH less than 6.5) a second application may be needed in the spring. Refer to instructions for split applications.
