During the past few cotton seasons in the CGA region there were approximately 20 spray drift reports per season, with nearly 40 unreported events per season.

Grower-led irrigation system comparison in the Gwydir Valley aims to collect commercially relevant comparative data on different irrigation systems.

River red gums are iconic in all cotton catchments and provide a number of valuable ecosystem services to growers, such as carbon sequestration, erosion mitigation and biodiversity conservation.

The Gwydir Valley region has been experiencing varying but rising levels of the incidence of Silver Leaf Whitefly (SLW) over the last few years, and the Macquarie is only a season or two behind.

This project evaluated and demonstrated nitrogen fertiliser and irrigation management strategies, including variable rate fertiliser applications, rotational cropping with legumes and matching fertiliser rates to crop
