The spray mechanism has advantages over mechanical devices (e.g. swinging or spinning blades) because they do not disturb the soil or cut roots, and in addition, they have less inertia and can be quicker in responding to a signal from the computer. However, spray mechanisms can potentially drift or wafting control materials onto the...
