Out-manage herbicide resistance with help from Liberty – the only Group 10 herbicide

InVigor plus Liberty equals profits plus herbicide resistance management.

InVigor canola is not just a great contributor to your bottom line it is also a great resistance management tool. Liberty is used in-crop on InVigor hybrids and other LibertyLink® canola varieties. It’s an excellent tool to limit the possibility of herbicide resistance developing on your farm. Liberty introduces a unique mode of action (Group 10) into your rotation. It’s better to manage the chance of resistance now before it develops.

Don’t limit your future crop potential. Understand your choices. Use a Group 10 with LibertyLink this season and keep your future cropping and herbicide options wide open, while maximizing your profits.

Liberty’s unique mode of action prevents weeds from detoxifying ammonia, a natural product of plant metabolism. When ammonia builds up to a critical point, the weeds die. Liberty is the only herbicide that works this way, so Liberty is in a herbicide class – Group 10 – that’s all on its own.

“The only time Group 10 is used in Western Canada is in canola with Liberty, which means a lower risk of weed resistance developing,” says Blaine Woycheshin, Portfolio Manager for Liberty with Bayer CropScience. “It also allows you to save your glyphosate for where and when you need it most. And it reduces the introduction of volunteer canola plants that affect weed control options in future years.”

Avoid using glyphosate when there are effective alternatives

Most growers know the importance of implementing integrated weed management practices and rotating herbicide groups every year. But sometimes glyphosate use becomes routine. Glyphosate has many uses and is a valuable tool on most farms, sometimes making it easy to slip into a pattern of over-use. Growers could conceivably use glyphosate three times in the same season on the same piece of land. The best remedy for limiting this use pattern is to rotate out of the group whenever other viable alternatives are available.

Liberty offers the weed control farmers need to grow a top-yielding canola crop while helping canola producers save glyphosate for field cleanups when it is needed the most. There are plenty of reasons to choose Liberty this season – aside from the fact that you’ll get excellent weed control.

Liberty tolerant hybrids set the bar higher

Prior to 2007 Pioneer’s 46A65 canola was the check for the Canola Council of Canada’s Prairie Canola Variety Trials (PCVT). InVigor hybrids tolerant to Liberty herbicide forced that bar higher and in the 2007 PCVT’s InVigor 5020 became one of the standard canola checks.

To see the latest PCVT trial results that were published in the Canola Digest click here. They demonstrate how InVigor hybrids are the only canola to yield as much as 115% above the check. (See 2007 all zone average column)

Out-manage herbicide resistance

Ways to avoid herbicide resistance:

• Where possible, rotate the use of Liberty, the only Group 10 herbicide with different herbicide groups that control the same weeds in a field when you are not growing InVigor hybrids or LibertyLink canola varieties.
• Tank mix herbicides from different groups when possible. By tank mixing, you are using two or more modes of action. For example using a tank mix of Liberty and Centurion is a sustainable management practice if you need to control advanced populations of wild oats. The Liberty will have activity on the smaller grasses and the Group 10 chemistry will mitigate any Group 1 resistance concerns. Ideally control wild oat populations before the tillering stage with an application of Liberty alone.
• Herbicide use should be based on an integrated pest management (IPM) program that includes scouting, historical information related to herbicide use and crop rotation, and considers tillage and other mechanical, cultural, biological or chemical control practices.
• Monitor treated weed populations for resistance development.
• Prevent movement of resistant weed seeds to other fields by cleaning harvesting and tillage equipment and planting clean seed.
