MDARD Michigan Core Pesticide Applicator Practice Exam

What is a key disadvantage of using gas (D) as an applicator method?

1. Usually ready-to-use

2. Good alternative where liquids could cause damage

3. High drift risk

4. Effective for indoor use

The correct answer is: High drift risk

Choosing gas as an applicator method has a notable disadvantage associated with high drift risk. This is particularly significant because gases can disperse easily into the air and travel considerable distances from the application site, potentially affecting non-target organisms and environments. The volatility of gas makes it difficult to control precisely where the pesticide will end up, increasing the likelihood of drift during application, especially in windy conditions. While gas may have some advantages, such as being ready to use or serving as a good alternative in some contexts, the primary concern revolves around the environmental safety and control issues linked with high drift potential. This characteristic limits the effectiveness and safety of gas application methods, necessitating careful consideration during pest management decisions.
