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.
Weed suppression is a visible reduction in weed competition (reduced population and/or vigor) as compared to an untreated area. Degree of suppression will vary with rate used, size of weeds and environmental conditions following treatment.
SPECIFIC WEED PROBLEMS
Foxtail/Pigeongrass (Green and Yellow): Fall applications at 1/3 oz/A in winter wheat or prior to planting spring wheat will suppress these foxtail species. Applications made in the spring (only on land that has been in fallow the previous year), also give suppression. For best results in the spring, apply preemergence to foxtail at 1/3 oz/A. Postemergence applications at 1/3 oz/A should be made with Surfactant before the foxtail is more than 1” tall or beyond the 1-2 leaf stage. 1/2 to 1” of rainfall is needed (after either a pre or postemergence treatment) to move REPORT into the weed root zone before the foxtail is beyond the 2-3 leaf stage, foxtail suppression may not be adequate.
Persian Darnel: Fall applications at 1/3 oz/A in winter wheat or prior to planting spring wheat will suppress Persian Darnel. Postemergence applications at 1/3 oz/A should be made with surfactant before the Persian Darnel is beyond the 2 leaf stage. Without adequate rainfall incorporation before the 3 leaf stage, Persian Darnel suppression may not be adequate.
Fall application may only provide short-term suppression. Sufficient rainfall after preemergence or postemergence treatment is necessary to move REPORT 2 to 3 inches into the weed root zone before weed seeds germinate and develop an established root system or before existing weeds grow beyond the seedling stage. In most areas, fall treatments provide the best opportunity for rainfall activation and most consistent residual weed control. Late spring applications may not receive enough rainfall after treatment resulting in poor weed control. Without sufficient rainfall to move REPORT into the weed root zone, weeds that germinate after treatment will not be controlled.
