Orchardists, nurserymen and hop growers share something in common – they want to get spray to the top of a tall plant canopy with as little waste as possible. The tops of trees, for example, are a primary site of infection as they filter spores from the air, so fungicide coverage is critical. Spraying the […]

What is the effect of volume on coverage? What is the effect of spray angle on coverage? This certainly wasn’t a scientific experiment. […]
