Why are some pesticides premixed with an emulsifier?

To prevent the active ingredient from dissolving in water.
To keep dry particles from sticking together in the tank mix.
To solidify the pesticide formulation for slow release.
To make the pesticide change color when applied.

The correct answer is: To keep dry particles from sticking together in the tank mix.

Pesticides are often mixed with an emulsifier to prevent the active ingredient from dissolving in water. This allows for a more uniform distribution of the pesticide when it is applied to crops or plants. A is incorrect because the emulsifier does not prevent the active ingredient from dissolving in water, rather it helps to distribute it evenly. C is incorrect because emulsifiers typically do not have a solidifying effect on pesticide formulations. D is incorrect because emulsifiers do not affect the color of the pesticide when applied. The purpose of an emulsifier is to keep dry particles from sticking together in the tank mix, making option B the correct answer.
