Indiana Pesticide Applicator Core Practice Exam

Which of the following options describes a limitation of dust formulations?

1. Attracts non-targets

2. Bulky to carry and apply

3. Requires agitation during mixing

4. Can degrade in moisture

The correct answer is: Attracts non-targets

Dust formulations have certain characteristics that can limit their effectiveness in specific situations. One key limitation is their tendency to attract non-target organisms. This can be a significant issue because the dust may not only affect the intended pest but also have negative impacts on beneficial insects or other wildlife. When using dust formulations, applicators need to be aware of this potential risk and take precautions to minimize unintended consequences in the surrounding environment. By attracting non-target species, dust formulations can disrupt local ecosystems and lead to a need for more targeted and careful application strategies. While the other options present valid considerations of dust formulations, they do not capture the specific ecological implications that come from the attraction of non-targets, thus highlighting why this answer addresses a critical limitation.
