What does the "75" in the name Lorsban 75WG refer to?

1. 75 lbs container

2. 75% active ingredient

3. 75% inactive ingredient

4. EPA registration number of the pesticide

The correct answer is: 75% active ingredient

The "75" in the name Lorsban 75WG signifies that the formulation contains 75% active ingredient. In pesticide products, the percentage of active ingredient is crucial as it indicates the strength and efficacy of the product. In this case, a higher percentage suggests that the product is more effective in its intended pest control application. When examining the other options, consider that the 75 lbs container option does not align with the typical naming conventions for pesticide products, which focus on the composition rather than the packaging size. The notion of 75% inactive ingredient is also misleading; while all pesticide formulations have inactive ingredients, the name typically highlights the percent of active ingredient instead. Lastly, the EPA registration number is a distinct identifier for regulatory purposes and would not be indicated in the product name itself. Thus, understanding that the "75" designates the proportion of the active ingredient helps clarify its significance in the product's effectiveness.
