Which of the following is NOT a disadvantage of emulsifiable concentrate pesticides?

Emulsifiable concentrate pesticides are a popular formulation due to their effectiveness and ease of use, but they do come with certain disadvantages. However, the statement about easily clogging nozzles and screens is not generally considered a disadvantage of emulsifiable concentrates.

Emulsifiable concentrates are designed to mix well with water and create a stable emulsion, which helps maintain flow through equipment during application. While they do require careful handling and proper calibration of spraying equipment to avoid clogs, the formulation itself is less likely to lead to nozzle and screen clogging compared to other types of pesticide formulations, such as wettable powders or granular formulations that can more easily block spray equipment.

On the other hand, higher phytotoxicity hazards, potential for skin absorption, and flammability are acknowledged issues with emulsifiable concentrates. They can have higher risks of causing plant damage (phytotoxicity) if not used correctly, and their formulation allows for greater absorption through the skin, which necessitates careful handling. Additionally, many emulsifiable concentrates contain organic solvents that can be flammable, creating safety concerns during storage and application.

Thus, the correct choice is that easily clogging nozzles and screens is not a disadvantage typically associated with emulsifiable concentrate pesticides.
