Which term describes a diluted pesticide?

• A. EC
• B. Suspension
• C. Concentrate
• D. Solution

Answer: (D)

A solution describes a diluted pesticide because it refers to a uniform liquid in which the active ingredient is dissolved in the solvent, giving an evenly mixed spray. When you follow label instructions and mix the pesticide with water, if the active ingredient dissolves completely, you end up with a true solution that distributes evenly and won’t separate or leave settled solids. This is different from an emulsifiable concentrate, which forms an emulsion with water and consists of droplets rather than a single dissolved phase. A suspension contains solid particles dispersed in liquid and may settle unless stirred. A concentrate is simply the undiluted form that must be diluted before use, but it doesn’t specify the state after dilution.
