Spray Patterns for Spot Sprays
Spot spraying promises to dramatically cut herbicide use. Data from Green-on-Brown (GoB) sprays suggest at least 50% and possibly 90% savings are possible, depending on weed density and the system employed. These savings are significant. But system performance depends on the nozzle selection even more than for broadcast sprays. What are the issues? Pattern Width […]

Coverage is King
We’ve often heard the adage “Coverage is King” but what does that mean, exactly?

Sprayer Nurse Truck Designs
We’ve recently been talking about how we can increase sprayer productivity by decreasing downtime. The main productivity robbers are time spent filling and cleaning. Using our productivity calculator, we’re able to show a 30% increase in acres per hour with some relatively simple changes to how we fill the sprayer. It’s important to actually measure the […]
