Last fall, I collected common milkweed (Asclepias syriaca) seed to establish some plots on a farmer cooperator's land over the winter. My plan was to seed directly into a standing cool-season grass adjacent to a crop field and determine the effectiveness of this method for plant...

Many people have high expectations for the new herbicide resistant traits, but it’s important to remember that these products are not the next “silver bullet” for successful weed management. A group of weed scientists in the eastern United States evaluated glyphosate resistant (GR) waterhemp and...

It looks like the month of March has arrived in December.
There have been rain amounts of 1.3 to 2.3 in the area. I know that is not much compared to the 3-4 inches of rain in central Iowa. However, it looks really wet in the area. There is water standing in the fields and water running...

In the past 10 years, herbicide resistance has grown into a significant problem that is limiting the ability of farmers to effectively control weeds. Farmers have relied on simple weed management in the past, but weeds have grown resistant to simple management systems....

It’s always difficult to forecast weather, but if dry field conditions persist, the potential for combine and field fires this fall will continue to be a problem. There have already been dozens of significant field fires around the state,...

It’s NH3 season, so here are some safety reminders from a guy who has seen how badly NH3 can injure people, first-hand. We work around it so much that sometimes we forget how caustic and dangerous it is.
