  1. List four factors to consider in choosing the equipment for applying a pesticide.
    • Target pest.
    • Site of application.
    • Size of the job.
    • Formulation used.
  2. List four factors a pesticide applicator must consider to carefully control the amount of pesticide deposited on the target.
    • Concentration of pesticide in the tank.
    • Rate of delivery.
    • Speed.
    • Area covered (swath width).
  3. List six components of ground spray application equipment.
    • Tank.
    • Agitator.
    • Strainer.
    • Pump.
    • Pressure regulator and gauges.
    • Control valves.
    • Hoses.
    • Nozzles.
  4. Describe solid cone (full) nozzles.
    Solid circular pattern; used for spraying foliage.
  5. Describe off-center nozzles.
    Wide flat fan patterns; used on boomless sprayers or directed spray rigs.
  6. Describe even flat fan nozzles.
    Uniform pattern across its width; used for band spraying.
  7. Describe hollow cone nozzles.
    Circular pattern with little or no spray in the center; used for spraying foliage.
  8. Describe flooding flat fan nozzles.
    Wide angle spray pattern; used for broadcast spraying.
  9. Describe flat fan nozzles.
    Narrow oval pattern with lighter edges; used for broadcast spraying.
  10. Describe solid stream nozzles.
    Compact jet used in handguns to spray a distant target or fixed to apply a narrow band or to inject into the soil.
  11. List the advantage and disadvantage of using a brass nozzle.
    The advantage of using a brass nozzle is that it is inexpensive. The disadvantage of using a brass nozzle are that it wears quickly from abrasion.
  12. List two advantages and one disadvantage of using a stainless steel nozzle.
    The advantages are that it will not corrode, and it resists abrasion. The disadvantage is that it is relatively expensive.
  13. List the advantage and disadvantage of using a plastic nozzle.
    The advantage is that it resists corrosion and abrasion. The disadvantage is that it swells with some solvents.
  14. List the advantage and disadvantage of using an aluminum spray nozzle.
    The advantage is that it resists some corrosive materials. The disadvantage is that it is corroded by some fertilizers.
  15. List the advantage and disadvantage of using tungsten carbide and ceramic spray nozzles.
    The advantage is that it is highly resistant to corrosion and abrasion. The disadvantage is that it is expensive.
  16. Name three variables that you can adjust to alter the delivery rate of a sprayer.
    • Change pressure.
    • Change speed.
    • Change nozzle tips.
