Which is a disadvantage of both EC and ULV formulations?

The correct choice identifies a significant disadvantage associated with both Emulsifiable Concentrate (EC) and Ultra-Low Volume (ULV) pesticide formulations: the potential for solvents to damage rubber or plastic components such as hoses, gaskets, pump parts, and other surfaces. EC formulations contain solvents that can dissolve or degrade certain materials, which is especially concerning in agricultural and application equipment that frequently uses these products. This deterioration can lead to equipment failure, leaks, and ultimately an increase in operational costs and safety hazards.

This issue is particularly relevant when considering the maintenance of application equipment that relies on these materials, which may compromise both performance and safety if not carefully monitored. Understanding the materials in use and their compatibility with different pesticide formulations is essential for effective management of pesticide applications to minimize risks and maintain equipment integrity.
