What characteristic do surfactants provide to pesticide sprays?

Surfactants are substances that reduce surface tension, allowing pesticide sprays to spread more evenly across the surface of plants or pests. By enhancing adhesion to surfaces, surfactants ensure that the pesticide remains in contact with the target area for a longer period, increasing its effectiveness. This characteristic is crucial for achieving thorough coverage on various surfaces, such as plant leaves, which can be smooth or waxy.

The role of surfactants in pesticide formulations contributes significantly to their performance by promoting better distribution and reducing the risk of runoff. This means that the pesticide can penetrate more thoroughly into the target organism or tissue, leading to improved control of pests or diseases. Surfactants play a vital part in the efficacy of pesticide applications and are essential for achieving optimal results.
