What characterizes an Emulsifiable Concentrate (EC) pesticide formulation?

It remains insoluble in water
It creates a milky emulsion when mixed with water
It contains only solid ingredients
It is always safe for organic farming

The correct answer is: It creates a milky emulsion when mixed with water

An Emulsifiable Concentrate (EC) pesticide formulation is distinctive because it forms a milky emulsion when mixed with water. This characteristic is due to the presence of emulsifiers, which help disperse the active ingredients into smaller droplets that intermingle with water. The ability to create a stable emulsion is essential for effective application, as it allows for a uniform distribution of the pesticide when sprayed. The other options do not accurately represent the characteristics of EC formulations. For instance, while some pesticides may remain insoluble in water, emulsifiable concentrates are specifically designed to mix well with water to form an emulsion. Additionally, EC formulations often include both liquid and active ingredients—not solely solids. It’s also important to note that being classified as an EC does not inherently imply that the formulation is suitable for organic farming, as the safety and regulatory status can vary significantly based on individual ingredients and formulations.
