Fall Weed Control Considerations (09/23/21)

Fall is often one of the best, and most overlooked, times for weed control. Here are a few considerations for different weed control scenarios as the calendar approaches October.

Weed Management is a Strategy and not a Tactical Activity (09/23/21)

Congratulations for navigating a challenging field season.

Controlling Broadleaf Weeds in Small Grains Stubble (08/05/21)

Small grain harvest is underway in eastern North Dakota and western Minnesota.

Preharvest Weed Control Options in Wheat (07/29/21)

The amount of kochia and other weeds poking their heads above our wheat canopies has triggered a lot of questions about options for preharvest weed control in wheat and other small grains.

Waterhemp is Flowering (07/21/21)

I was taking notes last week and observed flowering structures on waterhemp plants. Why is flowering important?

Waterhemlock Reported in Cass County (07/21/21)

I have received a couple questions and ID samples for spotted waterhemlock over the last two weeks.

Weed Control in Row Crops, a July 1 Assessment (07/08/21)

The Monday rain event meant some much-needed office time for administration. (07/08/21)

Grazing and Haying Restrictions for Herbicides (07/01/21)

Last week’s Crop and Pest featured a thorough article on considerations for haying or grazing small grain crops.

Project Safe Send Waste Pesticide Collection Dates and Location (07/01/21)

Farmers, ranchers, pesticide dealers and applicators, government agencies and homeowners should bring unusable pesticides to any of the 12 Project Safe Send collections in July.

Perennial Weed Control in Hot, Dry Weather (06/24/21)

I have been receiving several questions regarding control of noxious weeds during this year’s drought.

Postemergence Herbicide Applications in Hot, Droughty Conditions (06/10/21)

Some areas have received rainfall this week and that’s a brief relief from the above 90° temperatures, but the weather forecasts still predict some hot and dry weather as we enter peak postemergence spray season.

Controlling Weeds under Difficult Environmental Conditions. How Can I Control Waterhemp with Ultra Blazer without Injuring my Sugarbeet Crop? (6/10/21)

The good news is sugarbeet growers have been granted emergency exemption to use Ultra Blazer in sugarbeet. The bad news is environmental conditions are challenging, sugarbeet stands are inconsistent, and sugarbeet growth stage range from cotyledon to 6-lf stage in commercial fields in 2021.

Growth Stage Cutoffs for Herbicide Applications in Corn (06/10/21)

Despite our challenging start to 2021, many early planted corn fields are rapidly approaching the growth stage and height-restriction cutoffs for postemergence corn herbicides.

Controlling Waterhemp with Ultra Blazer without Injuring my Sugarbeet Crop? (06/10/21)

The good news is sugarbeet growers have been granted emergency exemption to use Ultra Blazer in sugarbeet. The bad news is environmental conditions are challenging, sugarbeet stands are inconsistent, and sugarbeet growth stage range from cotyledon to 6-lf stage in commercial fields in 2021.

EPA Approves Ultra Blazer in Sugarbeet (06/10/21)

The Environmental Protection Agency (EPA) approved our request for a Section 18 emergency exemption on June 2, 2021 for Ultra Blazer for control of waterhemp in sugarbeet in Minnesota and North Dakota.

Postemergence Herbicides in Wheat: What a Year (06/03/21)

What a week of temperature extremes. Many were still scouting for frost and freeze damage by the time forecast highs in the mid to upper 90’s were announced.

Common Lambsquarters Control with Glyphosate is Challenging under Environmental Stress Conditions (06/10/21)

One of my sugarbeet cooperative agriculturalist called and declared he has found a field with glyphosate resistant common lambquarters. Of course, I will investigate. However, I wonder if environmental conditions might explain this observation.

Dicamba Mixing Order for Xtend Soybeans (05/27/21)

Recently, my colleagues in the southern US have reported some issues on the commercial level when spray applicators are mixing dicamba formulations approved for use in Xtend soybean, glyphosate, and Sentris (a Volatility Reducing Agent/pH Modifier).

Dry Soils and Low Humidity Will Impact Air Temperature Inversion Timing, Duration, and Intensity (05/20/21)

North Dakota’s drought situation continues to grip most of the state. Because soils are drier than normal, they do not absorb as much solar radiation during daytime hours.

Germination Depth of Weeds (05/20/21)

Despite the ongoing dry conditions across the state, we are seeing a significant amount of summer annual weed emergence in many areas.

When Does Waterhemp Emerge and are there Tools to Forecast? (05/13/21)

Controlling waterhemp in sugarbeet has been my most important weed control challenge since arriving at NDSU in 2014.

You Planned for Lay-By Treatment in Sugarbeet? Consider a Preemergence Application. (05/13/21)

We often plan our weed management strategies during winter meetings or in brain-storming meetings around the coffee pot.

Soil Erosion and Herbicide Injury (05/13/21)

Off-target movement of herbicides is often associated with physical drift at the time of application. In addition, herbicides can move off the target site after application as a gas (volatility), in runoff water, and on sediments from wind-blown soil erosion.

Early Season Oddball Weeds (05/13/21)

Every spring we receive weed id samples of a few weeds that are easy to find across the landscape, yet do not pose much of a threat to crop production.

Weed of the Week Archives (05/13/21)

Starting last September, my team and I have been writing a weekly “weed of the week” article for the ANR Exchange e-newsletter.

It Has Not Rained. What is the Fate of my Preemergent Sugarbeet Herbicides?

Sugarbeet growers use soil residual herbicides at planting to control kochia or waterhemp.

Herbicide Supply Concerns in 2021 (05/06/21)

By now I am sure that most readers of Crop and Pest Report are aware of the supply concerns of certain herbicides this spring.

Weed Seed in Wind-Blown Soil (05/06/21)

The wind erosion events in late March and early April certainly caused a lot of coffee shop and Twitter talk for a number of good reasons worth discussing.
