The purpose of adding utility agents to a tank mix is to enhance the effectiveness of the primary pesticide. Utility agents can serve various roles, including improving the spread and adhesion of the pesticide on the target surface. They may act as surfactants, helping the pesticide to penetrate plant tissues more effectively or to remain effective longer in challenging environmental conditions.

When utility agents are included, they help to create a more uniform distribution of the pesticide, maximizing its performance by ensuring that active ingredients can reach their targets efficiently. This can ultimately lead to better results in pest control, as the pesticide is able to work more effectively due to the presence of the utility agent.

While buffering and stabilizing pH levels, increasing application speed, and enhancing visibility can all be important in certain contexts, the core role of utility agents is fundamentally tied to improving the pesticide's efficacy.
