What is a potential disadvantage of certain pesticide formulations?

The selected answer, which highlights increased cost as a potential disadvantage of certain pesticide formulations, is valid because some formulations may require advanced technology or specialized ingredients that can drive up their price. Additionally, high-quality formulations often formulated for effectiveness might come at a premium compared to basic or generic versions. This can limit accessibility for some users and may affect the overall cost-effectiveness of pest management strategies, making it a crucial consideration for applicators and consumers.

While lower efficacy is a concern in some cases, it's not a universal characteristic of all formulations. Moreover, ease of application is generally seen as a benefit rather than a disadvantage. Enhanced environmental safety would also be considered an advantage because formulations designed with this in mind aim to reduce adverse effects on non-target organisms and ecosystems. Thus, increased cost stands out as a relevant drawback when evaluating the practicality of pesticide use.
