Pressure Changes Spray Angles

Soybean demo plot sprayed with a contact herbicide using 110 degree air induction flat fans at 20 psi. The collapsed spray pattern did not overlap sufficiently to burn the entire crop down, leaving a striped pattern and demonstrating the poor coverage.

This work was performed with Victoria Radaukas, 2015 OMAFRA application technology summer student. When we consult a nozzle catalogue we are interested in the flow and droplet sizes produced at a given pressure. Perhaps we should also consider the effect of pressure on spray angle. We have several articles discussing the collective impact of spray […]
