Including corn in a crop rotation provides growers with a great opportunity to get a handle on problematic weeds, such as Palmer amaranth. Field Crop Agent, Anthony Growe, tells us how in this short video: Corn is a very competitive crop and when it’s planted on narrow row spacings, 30 inches or even down to 20 inches, canopy closure will ...

Weed management is a year-round job, but producers take special care to make sound management decisions prior to planting— including cover crop burndown. David Russell, an Alabama Extension weed scientist, offers suggestions for planting into a weed-free field and maintaining a clean corn crop throughout the growing season. His areas of specialization include corn, soybeans, small grains, forages and non-crops. ... Read More »
Corn and soybean producers know that an essential part of pest management is crop scouting. This subject is as vast as the tasks associated with it, and the benefits are evident to farmers. The Crop Protection Network has released a crop scouting and integrated pest management web book to assist agriculturalists. Why is crop scouting important? Crop scouting is an ... Read More »
• By Larry Steckel • Ready or not, burndown season is here! There has been very little burndown applied to date. Weather permitting, some would like to start corn planting before April 1. A potential short turnaround time from burndown to corn planting is most problematic in controlling ryegrass, particularly if the ryegrass is glyphosate resistant. There are really three ...

The Environmental Protection Agency recently registered Syngenta’s Acuron GT, a post-emergence herbicide for use on glyphosate-tolerant corn. State registrations are pending. Acuron GT combines the active ingredients in Halex GT corn herbicide — glyphosate, mesotrione and S-metolachlor — with the active ingredient bicyclopyrone added. This helps helps Acuron GT provide enhanced post-emergence control of yield-robbing weeds and longer-lasting residual in ... Read More »
• By Daniel Stephenson • Managing weeds in corn can be divided into three phases: preplant, in-crop and post-harvest, but I’ll save the post-harvest phase until later in the year. Preplant is otherwise known as burndown. We suggested applying a burndown herbicide four to six weeks prior to planting. Typically, glyphosate at 1 to 1.25 lb ae/A is the first ... Read More »
Weeds are the bane of most growers’ existence. In a growing class of “superweeds,” Palmer amaranth continues to frustrate farmers with its dogged resistance to commonly used herbicides. Research has shown that left unchecked Palmer amaranth can reduce corn yield by 91%. Different chemistries have been brought to market and enjoyed some control against the weed, yet many are no ...

Helm Agro US Inc. has received federal registration from the U.S. Environmental Protection Agency for Katagon, an HPPD premix herbicide for psotemergence use in field corn. It contains two modes of action — tolpyralate and nicosulfuron — with the added benefits of a low use-rate formulation, crop safety profile and a wide application window. When used as a tankmix with ... Read More »

The transaction closed Dec. 15, although Syngenta and Gowan will work together over the next several ... Read More »
As the 2020 corn-growing season draws to a close, Syngenta engaged university agricultural researchers from across the United States to analyze the agronomic challenges farmers encountered this season and offer tips on how they can best control weeds and preserve yields heading into 2021. Although weed pressures vary by geography, weed management fundamentals remain consistent throughout the United States. Researchers ... Read More »
