Why are there so many nozzles? Some pesticides work differently than others. Different types of nozzles are suited for applying different kinds of pesticides. For example, controlling aphids with an insecticide takes a different kind of droplet than controlling velvetleaf with a systemic herbicide (systemic means it can move within the plant to disrupt portions of the plant other than where the droplet landed)

Some nozzles make smaller droplets, while some make larger droplets. gernerally, we want droplet size to increase as we go from applying fungicides to insecticides to foliar (leaf-applied) herbicides to soil applied herbicides.

Nozzles are also important for making droplets the right size so they don't blow away, or "drift." So, we control the size of droplet we use by selecting a nozzle that makes the right droplet size and sprays them in a uniform pattern.
