At Corynnia Station, cotton farming has embraced cutting-edge biotechnology to maximize productivity and sustainability. Located on the edge of the NSW outback, Corynnia Station plays a pivotal role in Australia’s cotton industry, where genetically modified (GMO) cotton varieties have been used since 1996. Today, more than 99% of the cotton grown in Australia is genetically modified, and Corynnia Station is no exception. The use of GMO cotton brings significant benefits in pest management, weed control, and environmental sustainability.
The Role of GMO Cotton at Corynnia Station
Corynnia Station grows both Bt cotton and herbicide-tolerant cotton, which provide essential advantages for modern cotton farming. Bt cotton, developed using the Bacillus thuringiensis (Bt) bacterium, is resistant to the Helicoverpa spp. pest, a major threat to cotton crops. Bt cotton produces proteins toxic to this pest, dramatically reducing the need for chemical insecticides.
The current variety of Bt cotton grown at Corynnia Station is Bollgard 3®, which contains three insecticidal proteins (cry1Ac, cry2Ab, and vip3A). This “stacked” protein technology offers superior pest control, making it harder for Helicoverpa spp. to develop resistance.
In addition to pest resistance, Corynnia also grows Roundup Ready® cotton, which is herbicide-tolerant. This variety is resistant to glyphosate, the active ingredient in Roundup herbicide, allowing for more effective weed control. Herbicide-tolerant cotton reduces the need for tilling and offers greater flexibility in managing weeds, improving both crop yields and environmental outcomes.
The Benefits of GMO Cotton Farming
The introduction of GMO cotton at Corynnia Station and across Australia has led to remarkable environmental, social, and economic benefits. One of the most significant advantages has been the dramatic reduction in insecticide use. Before Bt cotton, Australian cotton farmers typically sprayed insecticides 10-14 times per season to manage pest populations. Today, that number has decreased by 97%, with cotton crops now requiring no more than 0-3 insecticide treatments per season. This reduction has not only lowered production costs but also minimized the environmental impact of pesticide use.
GMO cotton has also enhanced Integrated Pest Management (IPM) strategies, combining natural pest controls with targeted, pest-specific treatments to reduce the need for broader pesticide applications. The result is healthier ecosystems on cotton farms, with increased populations of beneficial insects and wildlife. Moreover, there is less pesticide run-off, which helps protect surrounding water resources.
The environmental benefits extend further with the use of herbicide-tolerant cotton. GMO cotton reduces the need for residual herbicides and soil tillage, which in turn decreases soil erosion and herbicide run-off. This sustainable approach helps preserve soil health and reduces the impact on the surrounding landscape.
Economic and Social Impact of Biotechnology at Corynnia Station
Corynnia Station benefits from the economic advantages that come with using GMO cotton. With improved pest control and weed management, the farm has seen increased cotton yields and reduced costs associated with labor, fuel, and chemical inputs. In fact, since the introduction of biotechnology in Australian cotton farming, the total farm income gain has been substantial. According to research by PG Economics UK, Australian cotton farmers gained an estimated $395 million in total farm income since 2010, which translates to about $180 per hectare.
For the farming community at Corynnia Station, biotechnology has also meant more time for family and a better work-life balance. With fewer pesticide applications and less tilling, farm workers spend less time in the field; leading to a safer and more sustainable working environment. Moreover, reduced pesticide use improves farm worker and community safety by lowering exposure to chemicals.
Corynnia Station’s Contribution to Sustainable Cotton Farming
Corynnia Station is the forefront of Australia’s sustainable cotton industry. The adoption of gmo cotton crops is a key factor in the farm’s ability to produce high-quality cotton efficiently while maintaining environmental stewardship. By reducing insecticide use, improving soil health, and managing water resources more effectively (60% less usage than 10 years ago), Corynnia Station is helping set a global standard for sustainable cotton farming.
