Before spraying Arrest or Slay:, Check the Arrest label and the Slay label  to be sure that the forage you want to spray is one that should be sprayed with that herbicide.  Arrest can be used to control most kinds of grass in any Imperial perennial blend, and in most other non-grass forages.  Slay can be used to control many broadleaf weed species, and a few of the heavier sedge-type grasses, in Imperial Whitetail Clover and any other clover or alfalfa. 

Before spraying Arrest or Slay:, Check the Arrest label and the Slay label to be sure before spraying that the grass or weed you want to control is one that Arrest or Slay is designed to control.  Slay will control most broadleaf weeds.

            Once you have confirmed these things, be sure to follow the mixing and herbicide-application instructions on the Arrest label and the Slay label. 

Surefire Surfactant and Surefire Seed Oil Plus:  Arrest and Slay are designed to offer optimum control of grasses or weeds before they mature.  The key is the age of the grass or weed - once it matures, it can be harder (but not necessarily impossible) to effectively control.  For best results, Arrest and Slay should be used when the grasses or weeds to be controlled are still in seedling stage (have not grown taller than 6-12 depending on the type weed or grass”).

If you are trying to control seedling grasses with Arrest, you do not have to add Surefire Surfactant or Surefire Seed Oil to the spray mixture. 

If you are trying to control perennial grasses, or any grass that has been allowed to mature beyond seedling stage (6” in height), then add Surefire Seed Oil Plus to the tank mixture.    

If you are trying to control seedling broadleaf weeds with Slay, add either Surefire Surfactant or Surefire Seed Oil to the spray mixture.  If you are trying to control broadleaf weeds that have matured beyond seedling stage, add Surefire Seed Oil Plus to the spray mixture.
