Which of the following is NOT listed as a liquid pesticide carrier?

• A. Water
• B. Liquid fertilizers
• C. Vegetable oils
• D. Gasoline

Answer: (D)

Pesticide carriers are liquids that transport or dissolve the active ingredient so the product can be applied effectively. Water is the most common carrier because it works with many formulations and is easy to handle. Vegetable oils are used as carriers for oil-based formulations, helping the active ingredient stay suspended or dissolved in an oil medium. Liquid fertilizers can be used in some tank-mix situations, depending on label directions and compatibility; they’re not typical carriers, but they can be involved in certain applications when approved. Gasoline, on the other hand, is not listed as a liquid pesticide carrier. It is highly flammable, toxic, and poses serious safety and regulatory concerns, so it’s not an approved carrier for pesticides. Therefore gasoline is the one not listed as a liquid pesticide carrier.
