Which carrier is typically not used for ULV pesticide spraying?

In the context of Ultra-Low Volume (ULV) pesticide spraying, oil is typically not used as a carrier. ULV spraying techniques rely on carriers that can effectively disperse the pesticide particles into fine droplets for efficient application. Air and gases are essential in ULV methods, as they help achieve the atomization of the pesticide, allowing for uniform and wide-area coverage.

Water is commonly used as a carrier in various pesticide formulations, including ULV applications, because it can dissolve or suspend many active ingredients, facilitating their delivery to the target area. Oil, on the other hand, while used in some pesticide formulations, does not align with the purpose of ULV application, which focuses on minimizing volume while maximizing efficacy through smaller droplet sizes. Therefore, it is not a standard carrier for ULV pesticide treatments.

This understanding highlights the importance of selecting appropriate carriers based on the desired application method and the characteristics of the pesticide being used.
