PRODUCT INFORMATION
F9870 HERBICIDE is a water dispersible granule formulation. F9870 HERBICIDE is to be mixed with water and applied to labeled crops for selective postemergence control of broadleaf weeds. Weed control is best when the product is applied to actively growing weeds up to 4 inches in height. F9870 is a contact and translocated herbicide with minimal residual activity at labeled use rates. F9870 HERBICIDE is rapidly absorbed through the foliage of plants. Within a few hours following application, the foliage of susceptible weeds show signs of desiccation, and in subsequent days, necrosis and death of the plant occur. Under some environmental conditions and with certain spray tank additives, herbicidal symptoms may appear on the crop. However, the crop recovers quickly with no loss in yield. Extremes in environmental conditions such as temperature, moisture, soil conditions, and cultural practices may affect the activity of F9870. Under warm moist conditions, herbicide symptoms may be accelerated. While under very dry conditions, the expression of herbicide symptoms is delayed, and weeds hardened off by drought are less susceptible to F9870.

APPLICATION INFORMATION 
Methods of Application 
F9870 HERBICIDE is a versatile herbicide utilizing several different application methods to achieve the desired results. If F9870 HERBICIDE is being applied in standing crop situations, application methods and adjustments must be precise to prevent undesirable effects to the desirable green stem tissue, foliage, blooms or fruit of the crop.

Ground Applications 
Utilize a boom and nozzle sprayer equipped with the appropriate nozzles, spray tips and screens and adjusted to provide optimum spray distribution and coverage at appropriate operating pressures. Utilize nozzles which produce minimal amounts of fine spray droplets. Apply a minimum of 10 gallons of finished spray per acre. Higher spray volumes are required when there is a dense weed population or crop canopy. Spray booms should be adjusted to position spray tips at the minimum height of 18" above the crop and operated to avoid the application of excessive herbicide rates directly over the rows and/or into the whorl of the crop. Be aware that overlaps and slower ground speeds while starting, stopping or turning while spraying may result in higher application rates and possible crop response.

Aerial Application 
Use nozzles and arrangements that will provide optimum coverage while producing a minimal amount of fine droplets. Use a minimum of 3 gallons of finished spray per acre. Higher spray volumes are required when there is a dense weed population or crop canopy. Take care to ensure that the application does not drift to non-target areas when applying by air.
