Per the label, for best results, Cimarron should be applied when rain is not expected for 48 hours when applied as a post emergent. Weed and brush control or suppression may be greatly reduced if rainfall, sprinkler irrigation or snowfall occurs 4 hours after the application. For pre-emergent applications 1-2 inches or rainfall or sprinkler irrigation (enough to we the top 2-3 inches of soil soil profile) is needed to move it into the weed root zone.
