Increasing Coverage with Crop-Adapted Spraying
Different crops require different kinds of spray coverage for best efficacy, so changing how spray is deposited can often provide beneficial results in both coverage and application efficacy. It starts with adapting how the crop is being targeted, ensuring maximizing spray deposition on the target area, and minimizing spray on less- ideal or wasted areas.
For example, using two spray tips straight down can provide better penetration through thick canopies, allowing for better interior canopy coverage; while two angled spray patterns forward & backward can lend to spray coverage at the top canopy foliage or on both front/back of a cereal head.
Why use two nozzles straight down, and not a multi-angle spray tip?
Further distance to target can mean less canopy penetration with angled

for double down spraying.
E.g. 5 + 10 gal/acre nozzles could be used for 15 gal/acre.
What about spraying vertical targets that don’t have a dense canopy?
Angled spray for vertical growing targets (e.g. cereal heads) can provide superior coverage
Spraying a vertical target is different than spraying into a canopy. Spraying forward/backward with a nozzles produces spray that can travel horizontal, making it more effective to cover vertical targets at suitable boom heights.
Picking Nozzles for Double-Down Spraying? Applicators often already have nozzles to be used in pairs
