What is the purpose of adding stickers to herbicides?

Adding stickers to herbicides primarily serves to help these chemicals adhere to leaf surfaces more effectively. To achieve the intended herbicidal action, it is crucial for the herbicide to remain on the foliage long enough to be absorbed by the plant. Stickers, or surfactants, improve the wetting and spreading properties of the herbicide solution, which enhances coverage and increases the likelihood of effective absorption by the target plant.

This adhesion is especially important in situations where environmental factors such as rain or heavy dew could wash away the herbicide before it has had a chance to work. By improving the adherence of the herbicide to the leaf surface, stickers contribute to more effective weed control and help ensure that the application achieves its desired results.
