Start the season with a clean fallow.

Consider any herbicide plant back restrictions.

Manage weeds using an Integrated Weed Management plan (IWM).

It is important that weeds are managed with an IWM plan to reduce weed seed set and future weed pressures. The Roundup Ready® Weed Resistance Management Plan and Roundup Ready Weed Management Guide by Monsanto will provide further information.

Consult the Roundup Ready Flex® Cotton Weed Management Guide for clear recommendations for weed control practices in a Roundup Ready Flex cotton crop. The guide includes a range of herbicides which offer different modes of action throughout the season, reducing the risk of glyphosate resistance developing on your farm and saving you time and money in the future.

The Roundup Ready Flex Cotton Weed Resistance Management Plan details strategies that can be implemented to minimise the risk of glyphosate resistance developing in weeds on-farm.

Act on early season weeds when they are small.

Ensure cotton is fully destroyed post harvest as then it becomes a woody weed.

Additional information is available from Monsanto on volunteer and ratoon cotton management.
