Fact Sheets

Pre-emergent (residual) herbicides are becoming increasingly important in weed control strategies in Central Queensland.

Ramularia leaf spot (RLS; grey mildew) in tropical cotton is a foliar disorder caused by Ramulariopsis sp. that can be easily identified by the presence of white to greyish spores on the underside of the leaf.

Rapid population growth of silverleaf whitefly (SLW) can occur from mid season onwards, particularly when natural enemies have been disrupted by insecticides. To reduce the amount of time required and help make SLW management more efficient, the recommendations for SLW sampling and thresholds have been simplified as of early 2024.

Gross Margin risk analysis: Water Use Efficiency.

Cavitoma is a rare phenomenon which is not experienced often locally, however there have been several incidents reported in Australian cotton growing valleys in 2023.

Download your copy of this new fact sheet to find out more about Cavitoma in cotton, some of the causes and how it can affect your crop.

Gross Margin risk analysis: nitrogen prices and NFUE

While there is little that can be done about the cost of nitrogen, growers can still manage their N input costs by looking at their nitrogen fertiliser use efficiency (NFUE).

This 2-page fact sheet from AgEcon produced for CottonInfo explains best practice in this space and what the current situation means for the cotton gross margin.

Seed cotton that is delivered to the gin contains three main components: fibre, seed, and trash. One of the major tasks of the gin is to separate the fibre from the seed and remove trash. From a grower’s perspective the amount and percentages of each of the three components are very important as they will determine their economic return.

This is commonly referred to as turn out and mostly quoted in percentage, with lint turn out (LTO%), sometimes to as gin turn out (GTO%) the most important, followed by seed and trash percentages.

This fact sheet looks at the costs and benefits of installing a floating photovoltaic (FPV) array. Three scenarios are explored using a case study site near Goondiwindi, QLD.

• Small scale (100 kW) off-grid
• Small scale (100 kW) on-grid
• Large scale (42,000 kW / 42 MW) on-grid
