Runoff
:
To reduce runoff from treated areas into aquatic habitats, avoid application to areas with a moderate to steep
slope, compacted soil or clay. Avoid application when heavy rain is forecast. Contamination of aquatic areas as a
result of runoff may be reduced by including a vegetative strip between the treated area and the edge of the water
body.
