The Sprayer Operator

Spray application is one of the most important activities regularly done in any crop operation. It can also be one of the most expensive and time-consuming.

Many operators use budget pressure gauges on their sprayers and have never changed them or tested their accuracy. This makes assessing sprayer performance and output difficult. Sprayer performance has a direct impact on coverage, efficiency, and efficacy because a faulty gauge may cause you to spray more or less product than you intended; read more […]
