Runoff Management Practices Implementation
Sound management of runoff benefits landowners, farmers and the environment. Land managers/ applicators must effectively implement mitigation measures that reduce, to the maximum extent practicable, runoff from treated fields. A variety of factors must be considered, including: Application Scheduling: • Do not apply this product when soil is saturated or at field capacity, or when a storm event likely to produce runoff from the treated area is forecast (by NOAA/National Weather Service, or other similar forecasting service) to occur within 48 hours following application. • Do not irrigate a treated field within 48 hours of application. Soil Hydrologic Grouping And Corresponding Mitigation Measures: • Users must know the soil hydrological type where application is occurring to implement required mitigation measures to prevent runoff. Soils are grouped into one of four categoies based on runoff potential; refer to the Enlist ® herbicide label for futher information about these hydrologic soil group (HSG) categories. • The required minimum criteria described for runoff mitigation measures are outlined at Enlist.com/MitigationMeasures . • The farmer/land manager will achieve mitigation measure “credits” toward the total required by implementing mitigation measures, such as using residue tillage; by managing field strips, buffers and neighboring vegetation; or by using contour farming, as shown in the table.
Mitigation Measures
Credits
Reduce number of applications: reduced number of applications of Enlist ® herbicides per year. Applications may be made at any time during crop development but must maintain a minimum 12-day re-treatment interval. Residue tillage management: no-till, strip-till, ridge-till and mulch-till
