LibertyLink® Soybeans Shine in 2012

MaxYield Coop Answer PlotWhen herbicide-resistant marestail and waterhemp began showing up in Wayne Koehler’s area two to three years ago, this Meservey-area farmer knew the LibertyLink® system could offer a viable solution.

“I’ve had good weed control in LibertyLink beans,” said Koehler, who began using LibertyLink system four years ago to grow seed beans. “I planted all LibertyLink beans this year, and they yielded just as well or better than other varieties in the area, which ranged from the mid-40s to 50 bushels per acre.”

Koehler’s success with LibertyLink hasn’t gone unnoticed, and some of the neighbors have also started switching to the LibertyLink system.

Take control of weed resistance issues

While LibertyLink is not a new technology, it has come to the forefront as herbicide-resistance issues have become more serious. LibertyLink can help manage the herbicide-resistant waterhemp, giant ragweed, and lambsquarters that are showing up in MaxYield’s trade territory, said Greg Sweeney, a MaxYield seed solutions specialist.

“Liberty herbicide does a good job of killing weeds,” said Sweeney, who noted that proper seed placement is important for success with LibertyLink varieties. “While other fields had major weed escapes in 2012, the LibertyLink fields in our area were extremely clean.”

Paying attention to details is the key to success with the LibertyLink system, added Koehler, who relies on Sweeney for seed solutions. “Some growers who tried Liberty in the past didn’t like it, but when you use the right sprayer nozzles and the right amount of water at the right pressure, you’ll have good results.”

Lessons from the South

These results are evident in the southern United States, where growers have been using both the LibertyLink and Roundup Ready® systems to manage herbicide resistance issues. “When some Iowa growers and I toured Mississippi and other areas of the South this summer, we saw how clean those fields were,” said Sweeney, who added that LibertyLink varieties yields are competitive with Roundup Ready varieties.

Southern growers have also adjusted their weed control systems to include more pre-emerge herbicides and no longer rely on just one chemistry or one mode of action, said Scott Gaskill, a Bayer CropScience field sales representative who works with MaxYield. In addition, these growers use full rates, rather than partial rates, of both pre-emerge and post-emerge herbicides.

“In the past, growers were using partial rates of glyphosate, because it controlled weeds and saved money. Over time, however, the weeds began to metabolize these reduced rates while continuing to grow. While glyphosate was dinging the weeds, it was no longer killing them.”

This is one reason why there’s a growing interest in LibertyLink among area farmers, said Mark Grundmeier, a seed product manager with Latham Hi-Tech Seeds, which offers a wide range of LibertyLink soybean varieties. “When farmers try the LibertyLink system for the first time, they are amazed at the level of herbicide performance they see and how clean their fields are.”

LibertyLink also offers an alternate method of weed control that will extend the useful life of glyphosate and Roundup Ready technology, Grundmeier noted. The importance of rotating crop protection products should be taken seriously, Koehler added.

“We shot ourselves in the foot by relying only on glyphosate. I’m glad we have options like LibertyLink. I’ve had no problems with this system and have been very satisfied with the results.”

LibertyLink varieties also perform well in high pH soils, which are common in MaxYield’s trade territory and can lead to iron chlorosis deficiency, said Sweeney, who encourages growers to try the LibertyLink system on one field. “We have enough options to put together a complete package for you in 2013.”
