What role do stickers, penetrants, and safeners play in spray mixtures?

They improve spray color.
They influence the adherence, absorption, or safety of a pesticide mixture.
They increase the speed of spray.
They decrease the effectiveness of pesticides.

The correct answer is: They influence the adherence, absorption, or safety of a pesticide mixture.

Stickers, penetrants, and safeners are additives commonly used in pesticide spray mixtures. They play an important role in improving the efficacy of pesticides by influencing their adherence and absorption onto the plant's surface. Additionally, they also ensure the safety of the pesticide mixture by reducing the potential for off-target drift and minimizing harmful effects on non-target plants and animals. Therefore, options A, C, and D are incorrect as they do not accurately describe the role of these additives in spray mixtures.
