What does a solvent primarily do in pesticide formulations?

In pesticide formulations, a solvent primarily acts as a carrier for the pesticide. This means that it dissolves the active ingredient of the pesticide, allowing for an even distribution of the pesticide when it is applied. Solvents help to facilitate the application process by keeping the active ingredients in solution, which can enhance the effectiveness of the pesticide by ensuring that it can be delivered to the target area effectively.

While other choices may express attributes that are associated with pesticides in different contexts, they do not accurately describe the primary function of a solvent. For instance, solvents do not inherently increase the strength or volume of a pesticide; rather, they maintain the concentration of the active ingredients. Additionally, solvents do not play a role in reducing toxicity levels; instead, their purpose is to ensure that the pesticide can be applied safely and effectively while maintaining its intended potency.
