Zamzows Defendz Crabgrass Preventer is a pre-emergent herbicide to control crabgrass in your lawn before it germinates!

This product contains Dimension herbicide and provides pre-emergence control of crabgrass and control or suppression of other listed weeds when applied prior to their germination. In addition, this product provides post-emergence control of seedling crabgrass after germination and emergence. Post-emergence control is limited to crabgrass only, but is effective up to 4 weeks after crabgrass has germinated!

Performance is improved if the application is followed by half an inch of rainfall or sprinkler irrigation. Erratic weed control may result if not activated by rainfall or irrigation within 30 days after application.
