Is Criterion 75 WSP Systemic Insecticide ideal for foliar spray on boxwood for leaf miner control?

My sprayer tank is 26 gallons. Can each envelop be divided to mix 300 gallon batch in portions as I use it?

Answer:

Criterion 75 WSP Systemic Insecticide is applied as a soil drench on trees, shrubs, listed flowers and groundcovers for treating leafminers or as a foliar. Each 1.6 oz pack will be mixed with 300 gallons of water (2.1 oz per acre) for foliar spray. When performing a soil drench, you will want to measure the trunk diameter or shrub height to determine mix ratio. Please let us know if you need anything else.
