Indiana Pesticide Applicator Core Practice Exam

Which disadvantage is associated with soluble powders in pesticide application?

1. Very safe for applicator

2. Difficult to achieve uniform application

3. Inhalation hazard

4. Can harm non-targets

The correct answer is: Inhalation hazard

The choice regarding inhalation hazard is correct due to the nature of soluble powders. When these powders are mixed with water and applied, they can create aerosolized particles that are fine enough to be easily inhaled by the applicator during mixing or application. This poses a significant risk to respiratory health, especially in poorly ventilated areas or without appropriate personal protective equipment. While the notion of safety and the potential for non-target harm are important considerations, they do not highlight the precise disadvantage connected with soluble powders themselves. Similarly, the challenge of achieving uniform application is a practical concern; however, it is less directly tied to the inherent risks posed by the application of these specific types of formulations compared to inhalation hazards.
