QAL Laws & Regulation Practice Exam

What is the defining characteristic of a Pesticide Dust (D)?

1. It should be applied in liquid form

2. It must not be used near electrical outlets

3. It is intended for broadcast application

4. It should be used with a duster

The correct answer is: It should be used with a duster

The defining characteristic of a Pesticide Dust is that it should be used with a duster. This application method ensures that the dust is evenly distributed in the targeted areas, allowing for effective pest control. Dust formulations are designed to be applied in this manner to achieve a thorough coverage of surfaces where pests may reside. In contrast, the other choices do not accurately reflect the unique qualities of pesticide dust. For example, applying pesticide dust in liquid form is incorrect, as dusts are specifically formulated to be dry and airborne. Additionally, while precautions may need to be taken around electrical outlets, this is not a defining characteristic of dusts but rather general safety advice. Lastly, broadcast application typically refers to liquid pesticides rather than dusts, which are usually applied in more targeted areas. Thus, the correct answer emphasizes the application method crucial for the use of pesticide dust, which directly impacts its efficacy.
