FORESTRY Commission Scotland is to step up the fight against tree pests and diseases by quantifying drift patterns by spraying a common food colouring from a helicopter.
Commission staff will undertake an aerial spraying trial, with no pesticides, to improve their understanding should this technique ever need to be used.
The trial will take place near Meall Mor approximately 10km south of Inverness and, subject to weather conditions, is scheduled within a ten day window from August 1 to 10.
