National Ag Week is being celebrated March 15-21 all across the United States, with Wednesday, March 18, designated as National Ag Day. As we celebrate National Ag Week, it is a good time to reflect on all the traditions and advancements that help make the U.S. agriculture industry second to none! Here are some interesting statistics about today’s agriculture industry....More
Emerged weeds have the potential to reduce crop yield. Agronomists and weed scientists recommend using more soil residual herbicides at full use rates to take weed stress off non-residual postemergence herbicides by introducing multiple, effective modes of action, different chemistries and controlling weeds for longer periods of time before they emerge. This strategy is called the Overlap System....More
What's an effective herbicide alternative to combat weed resistance? That's a question Bryan Young, associate professor of weed science, Purdue University, gets asked often. Being effective has to do with making sure that the herbicide alternative you're using can control the weed species, he says....More

Managing editor Susan Winsor spoke with Ford Baldwin about weed resistance problems and how growers can manage the resistance issues that keep moving farther north. Baldwin offered farmers 5 things they can watch and do to keep weed resistance from becoming and even bigger problem....More
Can soybean seeding rates be used as part of an integrated herbicide resistance management program? That's the question in a study published in Weed Science. Researchers conducted studies in 2012 and 2013 to determine the most effective seeding rates when used with or without pre-emergence herbicides....More
Mike Morgan lives the pigweed nightmare and wants to spare others. The Clay County, Ark., farmer teamed up with his neighbors to defeat Palmer amaranth in ditches, turnrows (headlands) and communal areas. This new weed weapon, a collaboration of farmers, is bent on stopping resistant weeds wherever they grow....More
Herbicides applied in the fall often can provide improved control of many winter annual weeds, including marestail, compared with similar applications made in the spring, says Aaron Hager, a University of Illinois weed scientist....More
The 5 ag stories featured this week offer management tips for wet soybeans, as well as advice for fall herbicide treatments. Read about possible corn acreage in 2015, and check out one farmer's strategy for keeping his farm ahead during lower-price years. For the weather obsessed (like me), see what NOAA is predicting for weather conditions across the U.S. this winter.
The EPA is registering the herbicide Enlist Duo with first-time ever restrictions to manage the problem of resistant weeds. The pesticide is for use in controlling weeds in corn and soybeans genetically-engineered (GE) to tolerate 2,4-D and glyphosate....More
“Do we need to till or not?” Purdue University weed scientist Bryan Young often hears this question from Midwest soybean growers fighting herbicide-resistant marestail, waterhemp and Palmer amaranth....More
This installment of 5 Agriculture stories to read reminds growers to adhere to herbicide rotation, and offers new research about using clover as a nitrogen source for corn. There is also help for making farm bill decisions regarding yield updates, and information on GMO safety and labeling, and the consumer's willingness to pay for it. Finally, read about a farmer who lost his cell phone in a grain bin, and had it turn up in Japan....More
If wet weather has delayed postemergence herbicide application to your soybean fields, there may be some large giant ragweed that needs treating. Mark Loux, Ohio State University, offers tips for herbicide application, depending on resistance levels....More
The USDA Economic Research Service released finding from a pesticide use study. Over the last five decades, pesticide use on corn, soybeans and other crops, as well as active ingredients, has changed dramatically in U.S. agriculture, including herbicide and insecticide use.
Wet or windy conditions may have kept farmers from applying a preemergence herbicide this spring. However, Bill Johnson and Travis Legleiter, experts from Purdue Extension say that many of these herbicides are still safe for farmers to use after corn has emerged so long as they pay close attention to product selection and application timing....More
This roundup of 5 agriculture stories you should read offers steps to decide if soybeans should be replanted, as well as some info on soybean injury from soil-applied herbicides, and corn-soybean price ratios. Also, see how one farmer makes aerial scouting affordable, and check out some jazz-loving cows....More
Due to late planting, and then wet, cool weather last week, some farmers were unable to apply a pre-emergence herbicide to corn. The University of Nebraska-Lincoln has some tips for applying a residual herbicide after corn emergence, including reminding growers to not apply herbicide with nitrogen, There is also a chart with corn stages, weed growth and the appropriate herbicides to apply....More
A recent trial by the University of Minnesota showed that using a preemergence (pre) herbicide in soybeans is beneficial, offering a significant reduction in weed densities early in the season. Weed escapes at the end of the season were nearly eliminated when using a pre herbicide, as well....More
Geez, the margin for error shrinks constantly, especially with weed resistance. The latest bulletin on this theme relates to Palmer amaranth’s tight control window—before 4 inches high. That gives you about 10 days....More
