The Roundup -

Resistant, Persistent Weeds Focus Ag Research Summit Webinar Feb. 25


February 17, 2021 | View PDF

Whether herbicide resistant or just aggressive spreaders, weeds are a constant plague in both crops and pastures, which is why management options are a key research subject for university and federal scientists. For Dr. Brian Jenks, North Dakota State University’s North Central Research Extension Center weed scientist, Minot, weeds have been at the heart of his research program for more than two decades.

That research and its application to local farms and ranches is featured in the fourth webinar of the 2021 MonDak Ag Research Summit Series – entitled 2021 weed control update in the MonDak – to be held at 10 a.m. MT, 11 a.m. CT, Thursday, Feb. 25.

As the keynote speaker for the Feb. 25 webinar, Dr. Jenks will share his take on difficult to control weeds such as kochia, horseweed and narrowleaf hawksbeard, as well as added information on weed resistance to commonly used herbicides; methods for making spring burndowns more effective, and new herbicides coming available.

Jenks’ holds a PhD in weed science from the University of Nebraska-Lincoln and conducts applied weed control research in most crops grown in western North Dakota.

Following him are three shorter presentations by USDA and MSU weed researchers in Sidney and Huntley, addressing weed issues found in rangeland, sugarbeet and aquatic systems:

• Purging Spurge: where are flea beetles most effective? - Dr. Natalie West, Pest Management Unit; USDA Agricultural Research Service; Northern Plains Agricultural Research Laboratory research ecologist, Sidney.

• Management of herbicide resistant weeds in sugarbeet systems - Dr. Lovreet Shergill, MSU Southern Agricultural Research Center Weed Scientist, Huntley.

• Aquatic invasive weeds in Montana and North Dakota - Dr. John Gaskin, Pest Management Unit; USDA Agricultural Research Service; Northern Plains Agricultural Research Laboratory research leader and research biologist, Sidney.

The webinar concludes at 11:30 a.m. MST/12:30 p.m. CST and is eligible for one pesticide recertification credit for Montana participants attending the live webinar. Sorry, viewing the subsequent recordings – to be made available online – does not qualify for points.

All interested persons are invited to participate and anyone can join the day of the event by using the following (Zoom program) link: No registration is needed to participate.

The MonDak Ag Research Summit is coordinated by MSU’s Eastern Agricultural Research Center; USDA ARS’s Northern Plains Agricultural Research Lab, both in Sidney; and NDSU’s Williston Research Extension Center, Williston. Normally a one-day, in-person event, this year’s MonDak Ag Research Summit was moved online due to COVID-19.

Remaining webinar dates and keynote presentations in the 2021-webinar series include the following:

• March 11: Seasonal Outlooks and Potential Climate Change Impacts for eastern Montana and western North Dakota - Patrick Gilchrist, NOAA, National Weather Service Station warning coordination meteorologist/service coordination hydrologist, Glasgow.

• March 25: Topic: marketing; Title: pending; Keynote - Dr. Vincent Smith, Initiative for Regulation and Applied Economic Analysis, Department of Agricultural Economics and Economics, Montana State University Professor, Bozeman.

Note, all webinars run from 10 a.m.-11:30 a.m. MST/11 a.m.-12:30 p.m. CST and include opportunities to ask questions of the speakers during the live sessions.
