Turn Out

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.

Practical on-farm tips for Verticillium management

Verticillium wilt is caused by the soil-borne fungal pathogen Vertillicum dahliae. The pathogen has a large range of hosts and is easily spread through soil and machinery. A strong integrated disease management (IDM) strategy is crucial for managing for Verticillium wilt. For more detail on the disease and management, visit the CottonInfo website or read the annual Cotton Pest Management Guide. 

Grey Mildew detected in the NT

Northern Australia cotton growers (NT, Nth Qld, WA) are encouraged to monitor and report any unusual symptoms in their crops, following the recent confirmation of grey mildew disease, caused by the fungal pathogen Ramulariopsis sp. 

If you see anything unusual on your farm, call the Exotic Plant Pest Hotline: 1800 084 881.
 

Managing for black root rot

Black root rot (BRR) occurs in all cotton growing regions however the regions that experience cooler planting temperatures show higher incidence and severity of the disease. Cooler starting temperatures  will slow cotton seedling development and it makes it difficult for seedlings to ‘outrun’ disease.

This fact sheet outlines management strategies and recent research into black root rot.
