The free herbicide resistance testing program is available to all growers who have grown Roundup Ready Flex® cotton in any of the prior 3 seasons. Growers can test five of the major weeds present in cotton systems for resistance to program herbicides.

• Annual Ryegrass (Lolium Rigidum)
• Awnless Barnyard Grass (Echinochloa Colonum)
• Liverseed Grass (Urochloa Panicoides)
• Red Pigweed (Portulaca Oleracea)
• Milk (Sow) Thistle (Sonchus Oleraceus)

TO PARTICIPATE IN THE RESISTANCE TESTING PROGRAM, SIMPLY FOLLOW THE BELOW STEPS:

1. Bayer have pre-printed testing envelopes that can be used for weed seed collection. Please contact your Regional Business Manager, or email australia.cotton@bayer.com.
2. Samples will be sent to Plant Science Consulting, who will do the testing and provide results directly to the grower.

For the 2022/23 season, cotton growers will be offered rebates for using participating products sprayed on Roundup Ready Flex cotton fields between 1 June 2022 and 1 May 2023.

Growers will also be eligible for a rebate on a single application of Roundup Ready® Herbicide with PLANTSHIELD® or Roundup Ready® PL Herbicide with PLANTSHIELD® Technology, if another program product is used on the same field.

Per hectare rebate is calculated at maximum label rate. Rebates will be adjusted accordingly for lower rates used. Rebates will not be paid for usage above the maximum label rate.

Growers should consult the Technology User Agreement (TUA) for full terms and conditions. Products are subject to availability and while stocks last.
