What does using spreader-stickers in pesticides relate to?

Using spreader-stickers in pesticides primarily relates to improving adhesion. Spreader-stickers are adjuvants that enhance the ability of the pesticide solution to adhere to the surface of the target organisms or the plants being treated. By promoting better adhesion, these additives ensure a more uniform application, which can result in more effective pest control.

When a pesticide adheres better to its intended target, it can remain on the surface longer and reduce the chances of being washed off by rain or irrigation. This increased adherence can significantly enhance the efficacy of the pesticide, leading to improved control of pests.

Other factors like absorption, toxicity, and evaporation also play a role in pesticide effectiveness, but spreader-stickers do not primarily focus on those aspects. Instead, their main function is to ensure that the applied pesticide stays in contact with the surface it is meant to treat for as long as possible.
