What is one disadvantage of both EC and ULV formulations?

difficult to handle, transport, and store
require constant agitation to keep in suspension
solvents may cause rubber or plastic hoses, gaskets, pump parts, and other surfaces to deteriorate
require specialized equipment for application

The correct answer is: solvents may cause rubber or plastic hoses, gaskets, pump parts, and other surfaces to deteriorate

The chosen answer highlights a significant issue regarding the compatibility of certain formulations with various materials. Both emulsifiable concentrate (EC) and ultra-low volume (ULV) formulations often contain solvents that can adversely affect rubber or plastic components found in application equipment. This deterioration can lead to leaks, malfunctions, or device failure, posing risks during application and potentially compromising effectiveness and safety. By addressing the materials used in these formulations, it draws attention to the critical aspect of equipment maintenance and compatibility that applicators must consider. Understanding this disadvantage aids in promoting proper equipment selection and retention of functionality over time, ensuring safer and more effective pesticide application practices.
