A rotational plan to control weeds

Cotton Field and Harvester

Rotating away from a cereal-based program with a broadleaf crop such as cotton allows the insertion of a disease and weed break into the crop rotation plan. The added ability to apply Roundup Ready herbicide with PLANTSHIELD® by Monsanto over the top of Roundup Ready Flex® cotton simplifies weed management.

Cotton’s fit into the rotation

There are countless ways of incorporating cotton into a dryland rotation. The below table shows some examples of rotations that are currently being used by growers. The key to these rotations is flexibility – being able to adjust depending on moisture availability, disease risks and the likely returns for each crop.

*Millet is a sacrificial crop grown for only 6 weeks and then sprayed out to provide ground cover, which helps harvest rainfall.

“Biotech has transformed cotton growing. The GM varieties make for simpler, cheaper and more effective weed and insect control.”

Jimmy King, Dryland Cotton Grower, Mullaley, NSW

“Having a broadleaf crop, in a predominately grass-crop system, provides a good opportunity to control problem weeds and the Roundup Ready technology has allowed people to get on top of problems, which benefits future crops.”
