What is a disadvantage of using an ultra low volume concentrate formulation?

• A. It is difficult to handle, transport, and store
• B. Specialized equipment is required
• C. The amount of visible residue on treated surfaces
• D. It tends to plug screens and nozzles

Answer: (B)

Ultra-low volume concentrate formulations are meant to be applied as extremely fine droplets, so they have to be atomized with equipment designed specifically for ULV use. That equipment carefully controls droplet size, flow, and application rate, and often relies on specialized nozzles, high precision regulators, and sometimes air or high pressure assistance. Because of this, the main downside is the need for that specialized equipment to apply the product correctly and safely—and the associated costs and training that come with it.

The other points aren’t as central to ULV use: handling, transporting, and storing ULV concentrates aren’t inherently more difficult than other concentrates; visible residue on treated surfaces isn’t a defining issue of ULV formulations, and plugging screens and nozzles isn’t a general problem specific to ULV concentrates.
