What primarily determines the type of nozzle used in aquatic applications?

The method of application is a critical factor in determining the type of nozzle used in aquatic applications. Different methods of application, such as surface spraying, sub-surface application, or aerial application, have specific requirements for droplet size, distribution pattern, and spray angle to effectively deliver the pesticide or herbicide to the intended target.

For instance, if a lower volume of product needs to be applied to the water surface, a nozzle that produces fine droplets may be more suitable to achieve optimal coverage and efficacy. Conversely, if the application method involves injecting chemicals directly into the water column, a nozzle designed for that purpose would be required.

In contrast, while the type of chemical and the size of the pump can influence the selection of equipment, they are secondary considerations when it comes to the precise needs dictated by the chosen application method. Environmental conditions can also play a role but are primarily related to safety and effectiveness rather than the nozzle selection itself.
