Commercial sweet corn growers must use spray application equipment capable of depositing spray material at the ear zone. These producers often hail from […]

This article continues from Part 1. Droplet size Droplet size influences droplet behaviour. The following table lists the pros and cons to changing droplet size when overall spray volume (e.g. L/ha) remains constant. Relative Spray Quality Pros Cons Coarser Droplets Lower drift potential because they resist deflection by wind and evaporation from heat and low […]
