The specifications detail the treatment rate, aircraft spray system, nozzle type and configuration, spray boom pressure, nozzle flow rate, volume median diameter (VMD) of the spray droplets, aircraft speed, treatment swath, and coverage rate for each type of aircraft. The State reserves the right to change or modify these requirements at its discretion.
This aerial application of insecticide is part of a state and local contract opportunity (ID: 668db6c4b7220a2c410c3b5e) for the California Department of Food and Agriculture to obtain a contractor to provide this service on an "as-needed" basis.
