Knowing how to recognize and manage soybean cyst nematode is the sole focus of a new pocket guide authored by Iowa State University Extension Nematologist Greg Tylka, in partnership between Iowa State University and the Iowa Soybean Association.

The current cold weather provides some relief from the wet grain issues that have plagued farmers in 2008. There is considerable corn in storage over 18 percent moisture, with some over 20 percent. And there is still wet corn in the field that likely will not dry any more.

Prior to 2005, foliar diseases were not of major concern to soybean production in Iowa and much of the north central region, except for soybean seed production. However, since the report of Asian soybean rust in South America in 2001 and then in the United States in 2004, interest in fungicide applications in soybean production has increased consistently, making use of fungicides on soybeans a hot topic.

Rain in May and early June this year put most alfalfa producers behind two to three weeks for their first, and correspondingly their second, third, and sometimes forth cuttings. Now in mid-November, producers can look back on the season, determine if there are still some management decisions to make and guess about winter survival.

As we observed a few weeks ago, the 2008 corn crop is wetter and lower in test weight than average corn. Long, cool growing seasons produce high yields but the corn is wet and soft, with more soft white starch. This means lower test weight, and reduced storability as mold can invade the softer textured kernels more rapidly. It also takes more energy to remove water from softer corn.
Integrated Crop Management (ICM) News is your link to the latest crop and weather interviews conducted by Doug Cooper, Iowa State University Extension communication specialist. Every Monday, Cooper visits with Extension climatologist Elwynn Taylor, integrated pest management specialist Rich Pope, and corn agronomist Roger Elmore or soybean agronomist Palle Pedersen. Once a month, Chad Hart, ISU grain markets specialist, is included in the program. Together, they take a look at the latest Iowa Crops and Weather report and the most recent USDA's Crop Production report.
