Which statement is true about the potential hazards of EC and ULV formulations?

• A. Increased environmental persistence.
• B. Solvents may deteriorate hoses and other surfaces.
• C. ULV formulations are always more effective.
• D. They have no odor.

Answer: (B)

Solvent components in EC and ULV formulations can attack and degrade equipment and surfaces. ECs rely on solvents to dissolve the active ingredient and enable emulsification, while ULV products use very small volumes with solvent carriers. Those solvents can soften, swell, or corrode hoses, gaskets, seals, and certain plastics in sprayer systems, leading to leaks and equipment failure. This is a practical hazard because damaged components affect spray consistency, safety, and performance. To prevent problems, use compatible, solvent-resistant materials for hoses and seals, inspect equipment regularly, and flush or clean lines after spraying. The other statements aren’t describing this equipment hazard: environmental persistence, while relevant in some contexts, isn’t a direct hazard to equipment; claims about universal effectiveness or lack of odor aren’t accurate reflections of these formulations.
