Bonide Sedge Ender Concentrate contains both a pre-emergent herbicide (Prodiamine) and a post-emergent herbicide (Sulfentrazone). Post-emergent would need to be reapplied if you have renewed weed growth. The pre-emergent will last up to 60-90 days depending on the rate used and rainfall in your area. Per the product label: In areas of extended growing season and heavy pressure weed control will be enhanced by second application of this product 60-90 days after initial application. Be sure to follow the label directions for rates depending on the type of turfgrass you have.
