While heated air drying is the fastest way to prepare late harvested crops for storage, bin drying with no/low heat (5 to 10 degrees) is often a more readily available second choice.

The soybean cyst nematode (SCN) causes greater annual yield losses in Kentucky than any other pathogen of soybean. The last time a formal survey was conducted by the University of Kentucky in 2006 and 2007, approximately 76% of soybean fields in the state were infested with SCN.

We are receiving calls, texts, etc. regarding poor quality soybean seed. Some have asked about grain inspection options. Whether a farmer brings in an inspector or takes them to a grain buyer, the soybeans must be harvested to get a grade rating.

After soybean plants have matured in the field, many organisms begin to grow and colonize these plants. Rainy weather often promotes growth of and colonization by these organisms. The longer that plants have been sitting in a field after they are mature, the more likely that they will be colonized by all types of organisms. Some of the organisms that are colonizing the soybean plants at this stage are soybean pathogens. The soybean pathogens that are best at colonizing these dead soybean plants generally are also good saprophytes, which means that they are able to grow and obtain nutrients from dead organic matter.

In 2017, there were several reports of Dectes presence in commercial fields in Webster, Henderson, and McLean counties in Kentucky. Soybean plants infested with Dectes larva or tunneling caused by this insect ranged from 25% to 55% (Villanueva et al. 2017). In 2018, I have received reports of fields infested with this pest from Christian, McLean, and Hickman counties, and from southern Illinois and southern Indiana.

Although soybean yields have been pretty good this year, the seed quality of harvested soybeans has not been great in some areas of the state. Seed diseases have been prevalent in areas that have received a lot of rain since harvest season began. Phomopsis seed decay (usually caused by Diaporthe longicolla, formerly known as Phomopsis longicolla) and purple seed stain (caused by Cercospora kikuchii and Cercospora flagellaris) are the two main culprits of poor quality seed.

The excessive rains of September and early October are more than many soybean plants can handle. The wet weather occurred as soybean seeds were at physiological maturity or approaching it. The entire plants were beginning to shut down as their mission of making seed was complete.

Several University of Kentucky soil scientists, an economist, a forage specialist, and other experts gathered in Princeton on October 3 to share findings from research that looked at getting rid of an issue for many western Kentucky farmers, the fragipan.

As Kentucky grain producers look ahead to 2019, they may want to consider adding wheat seeding to their plans this fall. The combination of wheat followed by double-crop soybeans is appearing to be more profitable for the upcoming marketing year compared to a corn-soybean rotation, said Todd Davis, University of Kentucky agricultural economist.

Rainfall and temperatures influences corn yield throughout its lifecycle, but especially during the seed fill period.

If flooding fully submerges corn in fields with soil temperatures above 70 degrees Fahrenheit for more than 24 hours, the corn will not survive. For corn at blacklayer, seed fill was complete. The flooding event, itself, will not affect seed fill. For corn that was near blacklayer, these plants will die prematurely, reducing yields. In either scenario, flooding will slow grain drying and possibly complicate harvest.
