What is the main purpose of a sticker in pesticide application?

The primary purpose of a sticker in pesticide application is to prevent pesticides from being washed off treated surfaces. Stickers are adjuvants formulated to improve the adhesion of pesticides to the target area, which is particularly important in aquatic environments. When a pesticide is applied to surfaces like leaves, soil, or water, factors such as rain, irrigation, or water movement can wash the pesticide away, reducing its effectiveness. By enhancing adhesion, a sticker ensures that the pesticide remains in place, allowing it to work effectively against pests or weeds.

This function is vital for maintaining the efficacy of the treatment, particularly in environments prone to water movement or precipitation. Utilizing a sticker helps ensure that the pesticide can fulfill its intended role without being easily displaced.
