Tools Needed

Peters Professional Liquid S.T.E.M. Fertilizer should be applied with a backpack sprayer, spray rig, or injector equipment.

How to Use

• Step 1: Depending on the application method, the rates will vary so it would be best to refer to the product label. To drench with a 1:100 injector, use 2 to 8 fl. oz. of Peters Professional Liquid S.T.E.M. Fertilizer per gallon of stock solution. To drench with a 1:200 injector, mix 4 to 16 fl. oz. of product per gallon of stock solution. Drench applications without an injector will use 2 to 8 fl. oz. of product in 100 gallons of water. For foliar spray application, apply 2 to 4 fl. oz. of product in 100 gallons of water.
• Step 2: To mix for injector equipment, you will need to pour half the amount of water needed and measured amount of Peters Professional Liquid S.T.E.M. Fertilizer into a separate tank. Add the remaining half of water into the tank and agitate until solution is well-mixed. You can repeat this mixing process for backpack sprayers with the exception of mixing in the sprayers tank instead of a separate one.
• Step 3: Spray the mixed Peters Professional Liquid S.T.E.M. Fertilizer as a drench or foliar spray until the top and bottom of crop leaves are wet, but not to the point of runoff.
