Texas Pesticide Applicator Practice Exam

Which type of formulation requires less overall agitation during application?

1. Fumigant

2. Wettable powder

3. Granular

4. Emulsifiable concentrate

The correct answer is: Emulsifiable concentrate

The type of formulation that requires less overall agitation during application is emulsifiable concentrate. Emulsifiable concentrates are designed to mix well with water and create a stable emulsion. This stability means that once mixed, they maintain their consistency without needing continuous agitation, allowing for a smooth application process. Fumigants typically are gases or volatile liquids that require specialized application equipment to distribute. Wettable powders often necessitate more agitation to keep the particles suspended in the solution, as they tend to settle at the bottom. Granular formulations are usually applied directly to the soil or surface without mixing in a liquid, which does not involve the same process of agitation but can be less effective for certain applications compared to a properly mixed emulsion. Therefore, the ease of application with emulsifiable concentrates due to their lower agitation requirements makes them a convenient choice in many pest control scenarios.
