What is a characteristic of ultra low volume (ULV) formulations?

Ultra low volume (ULV) formulations are characterized by their high concentration of active ingredients, which allows for effective pest control with the application of a significantly lower volume of product compared to traditional formulations. This high concentration enables the active ingredients to be delivered effectively while minimizing the volume of the carrier liquid, thereby reducing the environmental impact and potential harm associated with larger volumes of pesticide application.

This efficient use of active ingredients in ULV formulations is critical for targeting pests while also extending the range of application methods, such as fogging or aerosol dispersal, which can maximize coverage and efficacy.

In comparison, other characteristics denoted in the question, such as requiring large volumes or producing significant residue, do not align with the defining traits of ULV formulations.
