From weeds to insect pests to disease, resistance to efficient, economical crop protection products is threatening their efficacy and raising costs for crop producers. So why do regulations or the chemical industry always seem to have a delayed reaction to resistance? A big part of the problem involves dueling definitions, suggests Tim Dennehy, manager, Global Insect Resistance Management, Bayer Seeds....More

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

Also, read about some successful women farmers and the roles they play on the farm. Finally, enjoy the latest parody from the Peterson Farm Brothers, Takin' Care of Livestock.
Competition from weeds up to 4 inches only minimally affected nutrient acquisition by soybeans, while competition from weeds 8 inches or taller negatively affected acquisition. Soybean yields and grain oil content were reduced....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. Track growing degree days and field operations, and get fertilizer rates. Most of the apps are free, and most are available for iPhone and Android-based phones.
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
