What is the term used to describe a substance that enhances the adhesive properties of a spray?

The term that describes a substance designed to enhance the adhesive properties of a spray is "stickers." Stickers are additives included in pesticide formulations that improve the adherence of the spray solution to plant surfaces. By promoting better attachment, stickers help ensure that the active ingredients can remain on the foliage longer, which increases the effectiveness of the treatment against pests or diseases.

In contrast, while "adhesive," "spray modifier," and "binder" might refer to similar concepts, they do not specifically denote the purpose of enhancing adhesive properties in a spray formulation in the same way that stickers do. Adhesives are more general and may refer to a variety of binding products, while spray modifiers can refer to a broader category of substances that change the physical properties of a spray without specifically focusing on adhesion. Binders typically serve to hold particles together but may not specifically enhance the adherence of a spray to surfaces like stickers do.
