Agronomy: 2016 ILSoyAdvisor Field Days
If you grow soybeans, then you can’t miss out. The Illinois Soybean Association checkoff program has one goal—to help our state’s soybean farmers be the most knowledgeable and profitable soybean producers in the world. That’s why we launched the checkoff-funded ILSoyAdvisor.com platform—to help you become better soybean managers, increase your yields and make more money from every acre. For the second year in a row, we’re hosting a series of regional field days throughout the state—and we want to see you there. Come hear about the technology and practices that are increasing yields and profits at one of three regional [...]
Agronomy: Post Tank Mixes for Waterhemp
Controlling waterhemp is a challenge for growers across Illinois and the Corn Belt and the No. 1 subject of questions I received during the last week of June. So I decided to do a quick review of the 10 sites of action that make up 99.9% of what we have available for controlling weeds in corn and soybeans. Group 1 – ACCase inhibitors – These are products like Select Maxx®, Assure® II and Fulisade®. They are selective herbicides that only control grass weed species postemergence. Our main usage is controlling volunteer corn in soybeans. Because these do not control broadleaf [...]
Agronomy: Yellowing of Soybeans
One of the things we may observe in soybeans in June is yellowing, generally not field wide like nitrogen-deficient corn but more spotty and localized on some regions of the field landscape. Usually the crop grows out of it as the weather warms, soils dry and roots expand into a larger soil volume. However, there are a number of possible causes for yellowing, including: Failure to form nodules on roots Nitrogen immobilization Compaction Iron chlorosis Glyphosate flash Soybean cyst nematode Nutrient deficiency Nitrogen shortages: After a cool, wet spring into June your soybeans may yellow. I refer to this yellowing as [...]
Disease Management: Another Tool to Add to the SCN Armory
Soybean cyst nematodes (SCN) and root knot nematodes are both major pests in soybeans and reduce field yield potential. Genetic resistance is imperfect and the best solution is to rotate away from soybeans for at least a year or maybe longer if egg counts are in the thousands. Fortunately, a couple of seed treatments have come along that provide some additional control as part of a set of best management practices that includes crop rotation and genetic resistance. Those two products, VOTiVO® from Bayer and Clariva® from Syngenta, are applied to seed in combination with fungicides and insecticides. There is [...]
