Which of the following is an advantage of a blower type spreader?

Using a blower-type spreader offers the advantage of generating less dust compared to mechanical rotor centrifuge spreaders. This is particularly important in aquatic pest control, as minimizing dust dispersal helps to ensure that the granules remain on target, reducing the risk of environmental contamination and enhancing the effectiveness of the application. By limiting dust, a blower-type spreader can also contribute to safer working conditions for the applicator and surrounding wildlife, as there is less potential for unintended exposure to the chemical treatments being applied.

In contrast, while a blower type spreader does allow for faster application and can be more portable, these aspects are not as directly tied to the primary advantage highlighted in the context of reducing dust. The capacity to spread a wider variety of granules is also a valuable feature, but the focus in this instance is on the dust management capability.
