Managing Silverleaf Whitely in Australian Cotton

Silverleaf whitefly (SLW) is a major pest of mid to late-stage cotton. SLW honeydew is a serious contaminant of cotton lint, with the potential to harm our export reputation. 

This comprehensive fact sheet covers the whitefly species found in Australian cotton, SLW characteristics, lifecycle and ecology, how to manage SLW, best sampling strategies, how to use the management matrix, IPM for SLW, and also includes a table of registered insecticides for the control of SLW.

Counter sale guide for phenoxy herbicides

Phenoxy herbicides such as 2,4-D, MCPA and dicamba can cause damage to sensitive crops such as tomatoes, grapes and cotton. These crops are very sensitive to this group of herbicides and small amounts can result in significant yield loss.

This checklist is a handy reference for anyone selling or using phenoxy herbicides. The risk of crop damage can happen any time, but it is highest over the summer months.

Wet Picking & Soil Compaction

Clay soils in Australia largely underpin the cotton industry due to their excellent water-holding capabilities. However, this beneficial trait can pose challenges when rainfall coincides with cotton harvest season, particularly between defoliation and picking. When clay soils become wet, they lose their structural stability, become plastic and are vulnerable to compaction

Climate Analysis for Cotton Production across Northern Australia

Climate is the most important factor impacting cotton growth and development and how the crop might be managed in northern Australia. Solar radiation, temperature and rainfall interact in unique ways to create both opportunity and limitations for cotton production and understanding how climate interacts with the crop is fundamental to success in northern Australia.

Northern Australia Climate Review 2025

Northern Australia is characterised by its highly variable rainfall patterns, influenced by a range of complex climatic systems. For agricultural practices, especially in cotton farming understanding these precipitation dynamics is essential. This review highlights the key regions suitable for cotton cultivation, including the Northern Territory, parts of Queensland, and Western Australia, where tropical climates provide favourable conditions.
