How should the boom be oriented to the crop canopy?
The boom height should assure good coverage over the canopy. Match boom height to nozzle spacing to provide good coverage and avoid skips in the top canopy. A combination that works well is a nozzle spacing of 20 inches and a boom height of 12 to 18 inches above the canopy for wide-angle (110-degree) nozzles. Adjust the boom height as necessary to improve coverage and penetration. Some of the twin-nozzle configurations help with canopy penetration.
