What happens when the activity of one or more pesticides is altered by mixing them in a spray tank?

Calibration
Chemical Cartridge
Chemical Incompatibility
Certified Applicator

The correct answer is: Chemical Incompatibility

When pesticides are mixed in a spray tank, the different chemicals can interact with each other which may result in a change in their effectiveness or toxicity. This is known as chemical incompatibility. It is important for farmers and applicators to be aware of this and properly read and follow the instructions for each pesticide to avoid any negative impacts on the crops, environment, or human health. Calibration (A) refers to the process of adjusting a sprayer to deliver a specific amount of pesticide. Chemical cartridges (B) are filters used in respirators to protect against chemical exposure. Certified Applicator (D) refers to a person who has met the training and experience requirements to apply pesticides safely and effectively. While these options are important in the use of pesticides, they do not directly relate to the effects of mixing pesticides in a spray tank.
