If it's the new formula, it contains zeta-cypermethrin and bifenthrin. Originally Sevin products contained carbaryl (different Sevin products have changed active ingredients but I'm not sure which and when). The label on the new formula says "Certain plants such as annuals may be sensitive to the watered-in granules. A limited area should be treated and observed for one week prior to application to the entire planting." It also says don't apply at a rate more than 4lbs per 1,000 sq ft.
