For what kind of applications are sprays containing polymers primarily intended?

Sprays containing polymers are primarily intended for targeting surface weeds due to their ability to enhance the effectiveness and adherence of active ingredients on plant surfaces. Polymers can create a barrier that helps retain moisture, improve the spreading of the spray, and allows for better sticking to the leaves of the target weeds. This ensures that the herbicide remains on the foliage longer, increasing the chances of successful weed control.

In addition, polymers can offer a level of protection against environmental conditions like rain, which could otherwise wash away the herbicide before it has a chance to be absorbed by the plant. While they can also potentially aid in other applications, such as improving soil penetration or minimizing drift in aquatic environments, their primary use is focused on effectively targeting and managing surface vegetation, especially weeds.
