SPRAYING field headlands next to watercourses can be a time consuming and laborious operation under LERAP regulations.
The usual procedure is to spray herbicide around the field headland followed by a separate application of insecticide mix with the sprayers outer boom sections shut off. This is followed by a tank mix of both chemicals used for the remainder of the field.
To reduce the number of procedures, Gwent-based Application Control Systems has developed a system using Raven Chemical Injection to allow the operator to shut-off tank mix insecticides from certain boom sections – for use on land bordering watercourses.
The system works using a high pressure injection pump which selectively injects the required concentrated chemical just before the boom distribution valves.
A single channel control console governs the output of the pump according to forward speed, number of boom sections being fed and desired application rate.
In addition to spraying field boundaries, ACS says the system can be used for spot spraying with specific products, or for use with Roundup to spray off set-aside without having to wash out the main tank.
Designed to be retrofitted to any make of sprayer, the chemical injection system is priced at £5000 including extra spray valves, wiring harness and other components.
LERAP buffer zones can now be sprayed in one pass thanks to a chemical injection system from Application Control Systems.
