It is difficult to make a direct comparison between spraying systems that are relevant to every spray operator and the needs of each grain-growing enterprise.

Table 1 below ranks each spraying systems’ capacity to meet certain requirements. In some categories a function may not be currently available (indicated by ‘X’) or may be an option, which is indicated by a question mark.

Various operators will place different levels of importance on certain functions. For example, for some operators speed or volume range may be more important than canopy penetration; alternatively, ease of decontamination may be more important than single nozzle section control.
