Product Q&A

Answer:

There is no way to accurately mix down each Criterion 75 WSP Systemic Insecticide pack. You would need to use the whole pouch. You should apply 1 pouch or 1.6 oz of criterion for every 24 to 48 inches of trunk diameter.  You should apply the pouch in at least 10 gallons of water to apply the drench.  It really does not matter how much water you use, it just matters how much product you are applying over the area.  The more water you apply it with the deeper the ground will soak it up. Denser soils such as clay do not accept water as readily, so the lower volume of water is suggested.  Since sandy soils can accept more water, using the higher volume of water is preferred.
