Let’s act now before herbicide resistance becomes a bigger problem
The latest Herbicide Resistance news

Data from Agriculture and Agri-Food Canada's Neil Harker shows that in 2012 more glyphosate was applied to Western Canadian fields than all other herbicides combined.
"We're approaching a cliff," he says, because herbicides are "a precious limited resource." http://bit.ly/1kvl3pi
The hot topic at the recent annual California Weed Science Society meeting? Herbicide resistance.
Federal ag-scientist points out:
“We’re putting on $500 million a year in Western Canada worth of wild oat herbicides, so we can expect we’re going to get lots of resistance.” http://bit.ly/1ko2GUD

Here are some smart ways to manage and control the most problematic Group 2 herbicide-resistant weeds in your crops. http://bit.ly/1kBgrhM
89% of Canadian growers agree that they'll modify their growing practices to address herbicide resistance – but fewer than half think they actually have an issue. http://bit.ly/TblTgP
The goal for weed management can be summed up in two words: zero tolerance.
"You don’t even give these weeds a chance to go to seed.” http://bit.ly/1p5y4Xh
Australian expert says herbicide resistance is manageable:
Long before herbicide-resistant weeds were making headlines in the U.S., Australian wheat producers were taking steps to solve the problem. http://bit.ly/1cGXx1K
When members of the Certified Crop Advisor program were asked what they thought the next "silver bullet" in the fight against herbicide resistant weeds would be, 57% indicated knowledge and implementation of best management practices.

Waterhemp’s resistance mechanism to herbicides identified:
Weed science researchers at the University of Illinois have identified two unique mechanisms in the plant that have allowed the weed to "get around" these HPPD-inhibiting herbicides. To read more click here: http://bit.ly/1aS9S0g

Herbicide-resistant weed spreading fast in Indiana; threat a potential 'train wreck'
Aside from being able to produce up to a million seeds, controlling palmer amaranth requires an expensive cocktail of three or four herbicides at a cost of $50-$60 an acre, compared to $15-$20 and acre for less resistant weeds. To read more visit: http://indy.st/16miXAn
Why do soil-applied PPO-inhibiting herbicides seem to control PPO-resistant waterhemp populations that foliar-applied PPO-inhibiting herbicides do not control?
“Because the dose of the soil-applied herbicide is high enough to overcome the resistance mechanism, at least for a while,” Hager explained

Did you know:
Multiple resistance in weeds is the result of two or more separate resistance mechanisms in the same plant, whereas cross-resistance is the result of only a single resistance mechanism
6 weed management “non-negotiables” that will help growers get a handle on resistance according to weed scientist Jeff Stachler
1. Practice perimeter weed management: Anywhere weeds have a competitive advantage has to be addressed and not allowed to produce seeds
2. Practice zero tolerance: Allow no weeds to reproduce
3. Scout your fields
4. Diversify weed management strategies
5. Start clean: All weeds must be removed before planting
6. Maximize herbicide activity: Growers must choose the most effective herbicide(s) for the most difficult weeds in the field

Together, we’re going to do something about it
This campaign is designed to offer everything you need to know about herbicide resistance management, and to encourage all of us who work in Canadian agriculture to share experiences, insights and ideas.
We’ve identified the problem. Now it’s time to find a solution, together.
