Cotton Stewardship

Product stewardship is something Monsanto takes very seriously. Whether it’s ensuring environmental standards are not only met but exceeded, or protecting the safety of people and communities and ensuring the responsible use of our products. Monsanto’s stewardship commitments are a top priority.

As with all of Monsanto’s commercial traits, Bollgard® 3, Bollgard II® and Roundup Ready Flex® cotton have stewardship programs in place which are subject to ongoing monitoring, research and review. These stewardship programs ensure that all persons involved in the growing and management of the crop have a good understanding of the regulatory requirements, agronomic considerations and application options associated with the technology.

  • DEEDI also offer a Glyphosate Resistance Toolkit for growers and advisers which can be accessed on their website here.
  • WEEDpak synthesizes the results of extensive research on IWM in Australian cotton farming systems from research over the past 13 years.
    Download the WEEDpak manual which includes extensive reference material to help identify weeds, herbicide resistance, herbicides and their application, farm hygiene, the control of volunteer cotton, and weed control in rotation crops. 
    WEEDpak contains sections on Roundup Ready cotton management, the management of specific problem weeds and a species-specific best bet management guide, sourced from industry consultation.

Controlling volunteer and ratoon cotton

A key part of the Resistance Management Plan for growers of Bollgard II cotton is the control of volunteer and ratoon cotton.

This can, however, be difficult to achieve, as shown in a recent survey carried out by staff from the Queensland and New South Wales Departments of Primary Industries. Volunteer cotton plants from the previous season were present on 71% of cotton farms in QLD and 81% of cotton farms in NSW.

Volunteers can be controlled by not planting refuge crops into fields that were planted to Bollgard II the previous season. If this isn't possible, additional cultural and herbicide methods are available.

Controlling volunteers helps achieve resistance management, disease prevention and insect population control objectives.
