What type of adjuvant is specifically designed to enhance the adhesion of solid particles to the spray target?

Stickers are specifically designed to enhance the adhesion of solid particles to the spray target. When applied, they create a strong bond between the pesticide formulation and the surface being treated, which is particularly important for ensuring that solid particles, such as dust or granules, remain attached to surfaces like plant leaves, soil, or other substrates. This increased adhesion helps improve the effectiveness of the pesticide by reducing wash-off from rain or irrigation and ensuring that the active ingredients have ample time to act on the target organisms.

In contrast, surfactants primarily lower the surface tension of the liquid, which helps with the spreading and wetting of the spray solution across surfaces, but they do not specifically enhance adhesion like stickers do. Emulsifiers are used to stabilize mixtures of oil and water, helping to keep the formulation consistent and effective, but do not focus on adhesion. Spreaders are designed to increase the spread of the pesticide solution over the target surface, improving coverage, but again, their primary function does not involve enhancing adhesion in the same way stickers do.
