What does using spreader-stickers in pesticides relate to?

Using spreader-stickers in pesticides primarily relates to improving adhesion. These additives are designed to enhance the ability of the pesticide to adhere to the surfaces of plants and pests, ensuring that the chemical remains in contact with the target for a longer duration. This improved adhesion is essential for increasing the effectiveness of the pesticide by allowing it to work as intended, leading to better pest control.

While other factors like absorption, toxicity, and evaporation are important in pest management, spreader-stickers specifically target the surface interaction of the pesticide with the application area, thus making them more effective in their action.
