Which type of additive is added to a spray mixture to reduce drift during application?

Emulsifiable Concentrate (EC)
Drift Control Additive
Diluent
Dry Flowable (DF)

The correct answer is: Drift Control Additive

A drift control additive is added to a spray mixture to reduce drift during application, which improves the accuracy and efficiency of the spray. This process helps to ensure that the intended area is targeted and reduces possible harm to nearby areas. Option A, an Emulsifiable Concentrate (EC), is a type of pesticide formulation that contains an emulsifier and is not specifically designed to reduce drift. Option C, a diluent, is a substance added to a spray mixture to reduce its concentration but does not directly address drift. Option D, a Dry Flowable (DF), is a solid formulation that needs to be mixed with water before application and does not have properties to reduce drift. Therefore, the correct and most effective option is B, a drift control additive.
