What is the general rule of thumb for treating the surface area of water?

The general rule of thumb for treating the surface area of water emphasizes treating only a portion of the area at a time, typically around one-quarter to one-third. This approach is important for several reasons.

First, treating too much of the water surface at once can lead to sudden shifts in the ecosystem. A full treatment may remove a large number of aquatic plants or organisms, which can disrupt the balance of the aquatic environment and negatively affect water quality or fish populations.

Second, treating in smaller sections allows for better management of the results. By monitoring the effects of the treatment on a smaller scale, applicators can make more informed decisions about the need for further treatment and adjust their strategies based on observed outcomes.

Lastly, treating only a portion at a time helps to reduce the potential for pesticide resistance among aquatic pests, as it allows untreated areas to serve as refuges for pests that may otherwise develop resistance if large-scale applications were made consistently.

In summary, treating only one-quarter to one-third of the surface area at a time is a responsible approach that aims to balance effective pest control with the health of the aquatic ecosystem.
