What is the function of nozzles in bottom placement or deep-water injection methods?

The function of nozzles in bottom placement or deep-water injection methods is primarily to deliver the chemical effectively at the bottom of the water body. This technique ensures that the pesticide is released directly to the targeted area where aquatic pests are typically found. By positioning the nozzles to inject the chemical at the bottom, applicators can maximize the efficiency of the treatment and minimize the potential for chemical drift or dispersion at the surface.

Using nozzles in this manner allows for more precise application, which is crucial when dealing with aquatic environments. It helps in achieving effective pest control while safeguarding non-target species and reducing environmental impact. The placement of the nozzles and the pressure at which the chemical is delivered are designed specifically for this deep-water approach. Therefore, it is important to understand that delivering the chemical to the bottom is central to the efficacy of this control strategy.
