Texas Pesticide Applicator Practice Exam

Which formulation is most appropriate for agricultural environments where visibility of pesticide residues is a concern?

1. Granular

2. Aerosol

3. Emulsifiable concentrate

4. Wettable powder

The correct answer is: Emulsifiable concentrate

In agricultural environments where visibility of pesticide residues is a concern, emulsifiable concentrates are particularly advantageous. This formulation type creates a clear or transparent solution when mixed with water, which typically results in less visible residue on crops, surfaces, and soil after application. This is especially important for growers who want to maintain the visual appeal of their produce and minimize aesthetic concerns for consumers and markets. Granular formulations are generally more visible when applied, as they consist of small solid particles that can remain on the surface of plants or soil. Aerosols often leave a visible spray pattern and can produce a mist that may settle unevenly, while wettable powders can leave a visible white or colored residue after drying on the target surfaces. Therefore, for environments where minimizing visual residue is crucial, emulsifiable concentrates stand out as the most suitable choice.
