What is added to a spray tank to assist pesticide in its application?

Injector
Adjuvant
Inert helper
Mix enhancer

The correct answer is: Adjuvant

An injector is a device used for mixing substances into a fluid system, but it is not specific to pesticide application. An inert helper is not a commonly known term in pesticide application and does not accurately describe adding a substance to assist with application. A mix enhancer may improve the overall efficacy and effectiveness of a pesticide mixture, but it is not the specific term used for a substance added to a spray tank to assist with application. An adjuvant is a substance added to a pesticide mixture to improve its application and effectiveness. It helps the pesticide spread evenly, stick to plant surfaces, and penetrate pest resistance. It also helps reduce drift and increases rainfastness. Therefore, option B, adjuvant, is the correct answer.
