Oregon Pesticide Practice Test

Which statement about pesticide label names and ingredients is true?

1. All manufacturers use the same trade names for active ingredients

2. Only one trade name exists for each active ingredient

3. Various manufacturers use different trade names for the same active ingredient

4. The active ingredient is always listed first on the label

The correct answer is: Various manufacturers use different trade names for the same active ingredient

The statement indicating that various manufacturers use different trade names for the same active ingredient is correct. This reflects the reality of the pesticide market, where manufacturers often develop their own brands or trade names for products containing the same active ingredient. This practice allows for competition and differentiation in the marketplace, enabling consumers to choose from multiple products based on brand preference, marketing, or perceived efficacy. Trade names are unique to each manufacturer's product and may not necessarily reflect the chemical composition. Thus, it is common for different companies to sell products that contain identical active ingredients but under varied trade names. This variety enhances consumer options while ensuring that the same active ingredient may be used for similar pest control purposes across multiple products. In contrast, the other statements do not hold true. Different manufacturers can certainly use various trade names for the same active ingredient. Additionally, it is possible for more than one trade name to exist for a single active ingredient due to variations in formulations or product lines. Finally, while many pesticide labels do feature the active ingredient prominently, it is not a rule that the active ingredient is always listed first. This can vary based on the manufacturer and how they choose to present the information on their labels.
