With placement (localised) spraying of broad spectrum pesticides, considerable efforts have been made to quantify and control spray drift from hydraulic nozzles. [11] Conversely, wind drift is also an efficient mechanism for moving droplets of an appropriate size range to their targets over a wide area with ultra-low volume (ULV) spraying.
Preemergent herbicides are a form of chemical weed control which prevent germinated weed seedlings from becoming established. In some areas of the world, they are used to prevent crabgrass from appearing in lawns.
