To determine how much pesticide or fertilizer is needed to do a job, first calculate the size of the area to be treated. It employs different units so it requires a different constant: [broadcast output (L/ha) x travel speed (m/min) x (swath width (m)) number of nozzles per swath)] 10,000 (m2/ha) = nozzle output (L/min). Spray Tank Capacity (L) = total capacity of the sprayer tank. A banded application is treating parallel bands (Figure one), unlike a broadcast application where the entire area is treated (Figure two). These are all key steps in a successful pesticide application. The label states that the contents of the bag will cover 5,000 square feet. Nozzle material is important in reducing inaccurate applications due to nozzle wear.
