Minnesota Pesticide Applicator Practice Test

Which behavior is NOT recommended when applying pesticides?

1. Insuring good weather conditions

2. Wearing protective gear

3. Mixing several pesticides together without guidance

4. Cleaning equipment after each use

The correct answer is: Mixing several pesticides together without guidance

Mixing several pesticides together without guidance is not recommended because it can lead to harmful consequences. When different pesticides are combined, there is a risk of creating chemical reactions that may not only decrease their effectiveness but also produce toxic byproducts that can be dangerous to both the applicator and the environment. Proper guidance ensures that the chemical compatibility of the pesticides is understood, which helps in preventing unintended reactions and ensuring safe handling practices. In contrast, ensuring good weather conditions, wearing protective gear, and cleaning equipment after each use are all practices designed to enhance safety and efficacy in pesticide application. Good weather conditions minimize drift and runoff, protective gear protects the applicator from exposure, and cleaning equipment prevents cross-contamination of chemicals, all contributing to responsible pesticide use.
