How many ounces are in a full backpack of Bifen?

• A. 0.5 ounces
• B. 0.25 ounces
• C. 2 ounces
• D. 1 ounce

Answer: (C)

Understanding how to mix concentrate with water for a spray device is key here. When using Bifen, you dilute the concentrate with water at a specific rate per gallon of spray solution. A typical full backpack sprayer holds about 4 gallons of solution. If the label directs using 0.5 ounce of Bifen per gallon of water, then the total amount of concentrate needed for a full backpack is 0.5 oz/gallon × 4 gallons = two ounces. So, a full backpack requires two ounces of Bifen concentrate to achieve the correct dilution. Using less per gallon would under-dose and reduce effectiveness, while using more per gallon would overshoot the label’s guidance and could raise safety or efficacy concerns.
