Michigan Commercial and National Pesticide Applicator Practice Test

The ultra low volume (ULV) formulation is designed to be applied in small volumes of liquid, which means it requires significantly less water when compared to other pesticide formulations. ULV formulations are concentrated products that can be effective even when mixed with very little carrier volume, often less than 1 gallon per acre. This makes them particularly useful for applications in situations where minimizing water use is critical, such as in areas with sensitive ecosystems or in situations requiring targeted pest control.

In contrast, ready-to-use (RTU) formulations are pre-mixed and typically come in consumer-friendly packages that do not require additional water but usually contain more liquid than ULV. Water-dispersible granules (WDG) require water to dissolve the granules before application, leading to a higher overall water requirement. Granular pesticides are solid formulations that do not require any water for application but are spread directly on targeted areas, making them suitable for certain applications but not defined by low water volume requirements.
