Which statement about emulsifiable concentrates (EC) is true?

• A. They can deteriorate equipment parts due to solvents.
• B. They are relatively easy to handle, transport, and store.
• C. They have no odor.
• D. They never plug screens or nozzles.

Answer: (B)

Emulsifiable concentrates are solvent-based liquid pesticide formulations that mix with water to form an emulsion. Because they’re concentrated liquids, they’re typically straightforward to measure, mix, and use, and their containers are easy to store and transport in standard sprayer kits. This makes them relatively easy to handle, transport, and store compared with some other formulations such as dry powders or granules that may require special handling or more careful packaging. The statement about having no odor isn’t accurate, since ECs usually carry noticeable solvent odors. The notion that they never plug screens or nozzles isn’t correct either—solvent-rich emulsions can clog or foul screens and nozzles if not properly filtered and rinsed after use. And while solvents can affect certain equipment components over time, proper sprayer materials and regular maintenance help manage that risk. So, the general, practical takeaway is that ECs are typically easier to handle, transport, and store, compared with many other formulations.
