Targeted aerial application of herbicides onto individual and small clumps of trees is an important tool for wilding conifer control, particularly in inaccessible or hazardous areas such as steep alpine country. In these situations, scattered trees can be sparsely spread over large landscapes resulting in targeted aerial spraying of herbicides using helicopters as the only current practicable control method. There is a variability in the amount of herbicide used during targeted Aerial Basal Bark Application (ABBA) and foliar spot spraying. Operators want to ensure the trees are ‘killed’ given the often-remote locations and costs associated with any follow-up control work. It is likely that application amounts can be reduced.

The objective of this project is to obtain the research required to carry out two experiments looking at quantifying the spray drift amount and optimal herbicide application rates for targeted aerial spray.
