Wyoming Pesticide Applicator Certification Practice Test

An Emulsifiable Concentrate (EC) is usually formed as a milky emulsion when combined with water, making it the correct answer. This type of pesticide formulation is designed to mix easily with water, allowing it to be sprayed effectively with minimal clogging of equipment. The other options, a Drift Control Additive, Drop Spreader, and Dry Flowable (DF), are not formulated as emulsions when combined with water. A Drift Control Additive is specifically used to reduce spray drift during pesticide application and does not form an emulsion. A Drop Spreader is a type of spreader used to evenly distribute granular pesticides, while a Dry Flowable (DF) is a type of dry powder formulation that can be easily mixed with water and does not form an emulsion. These options are not the best fit for the given question.
