NCGA and ASA are concerned that a pending announcement from the U.N. World Health Organization’s International Agency for Research on Cancer will only lead to more confusion and concern about two widely-used herbicides that have been mainstays for farmers for decades. These two substances play an especially important role in corn and soybean farming as they allow us to manage weeds in a sustainable way....More

Most, but not all, soil residual herbicides can be applied after corn has emerged. Labels usually indicate a maximum corn growth stage beyond which applications should not occur. These growth stages can range from as early as two leaf collars to as late as 40-inch tall corn, so be sure to consult the respective product labels....More
This spring, let your smart phone help you as you head to the field. Download these apps to calculate seeding rates and fertilizer applications, as well as input calculators.

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
In the 5 ag stories to read this week, get some considerations for seed treatments when trying to cut costs this spring. If you plant cover crops, be aware of residual herbicides, and there's still time to sign up for the Conservation Stewardship Program. Read 5 tillage myths, and watch a video thanking farmers, that also helps FFA.
In the 5 ag stories to read this week, learn how farmers are becoming more compliant when planting a refuge for Bt corn, and make your farm bill choices in seven steps.

New weed control options, which include both veteran and new active ingredients, cleared major milestones on the road to commercialization in 2014. Dow AgroSciences, Monsanto and Syngenta have new herbicides available (or soon to be available) to growers to help combat resistant weeds in 2015....More
The spread of multi-resistant waterhemp has led to increasing use of Group 14 herbicides, the protoporphyrinogen oxidase (PPO) inhibitors that include Cobra, Flexstar, Ultra Blazer and others. Repeated use is exerting intense pressure on this diverse group of chemicals, weed experts warn....More
This is the second of a two-part article highlighting what happened agriculturally in 2014. Last week’s article provided a review of 2014 crop production and weather conditions. This week we will focus on some highlights regarding input costs, grain prices and the overall farm economy for 2014....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
