Herbicide Resistance Summit, 2016

The 2016 Herbicide Resistance Summit was held in Saskatoon on March 3, to a full house of farmers and scientists.

Robin Booker from The Western Producer teamed up with Lisa Guenther from Grainews and interviewed event presenters.

The following video is a collection of their interviews, which include:

Australian weed scientist, Ian Heap, is the director of the International Survey of Herbicide Resistant Weeds and he presented an overview of the state of herbicide resistant weeds in the world.

Hugh Beckie, weed scientist at Agriculture and Agri-Food Canada, speaks on the herbicide resistant weed problem on the Prairies.

Jason Norsworthy has been studying the development of herbicide resistant weeds in the U.S. and he discusses what producers should be aware of when using herbicides that have two modes of action.

Ontario weed scientist Peter Sikkema discusses how Canada fleabane is spreading in Ontario, and what producers can do to stop it.

Breanne Tidemann is working towards a Ph.D. at the University of Alberta, and she discusses some of her work that looks a which Prairie weeds might be vulnerable to harvest weed seed control.


Here are some stories from the 2016 Herbicide Resistance Summit:

No chemical solution for resistance: There is no chemical solution to the problem of herbicide resistance, says University of Arkansas weed scientist Jason Norsworthy.

Instead, industry should focus on integrating weed management techniques to combat resistance.

Study examines harvested weed seed control: Harvested weed seed control is a strategy to prevent viable weed seeds from returning to the field at harvest.

It has proven useful in Australia in the fight against herbicide resistant weeds such as rigid ryegrass.

Herbicide resistance major problem in Canada:  Canada places third on the list of countries with the highest number of herbicide resistant weeds.

North America has more resistant weeds than other continent.


Resistant weeds found on half of Sask. acres:  The latest Saskatchewan weed survey indicates herbicide resistance continues to spread, and more than half of the seeded fields in the province have herbicide resistant weeds.

Growers urged to develop wild oats management plan:  Wild oats costs farmers in Western Canada half a billion dollars to control annually.

That’s more than double any other weed species.
