What factors should be considered when selecting a pesticide formulation?

When selecting a pesticide formulation, it is crucial to consider the active ingredient's registered use. This is because the registered use indicates the specific pests, plants, or situations for which the pesticide can be applied effectively and legally. Understanding the registered uses ensures that the applicator chooses a formulation appropriate for the target problem and complies with regulations. This factor directly impacts both the efficacy of pest control and adherence to safety guidelines.

Considering factors like cost, color, and convenience of packaging can influence purchasing decisions but do not determine the effectiveness or legality of pesticide use. The main focus should always be on ensuring the pesticide is suitable for the intended application, which is inherently tied to the registered uses of its active ingredients.
