Here’s a pivot that has full season soybeans on the left side. On the right a crop of field corn was grown and then these Ultra late soybeans were planted and they are still green and growing strong. The beans that were planted early are turning yellow and dropping leaves as they approach maturity.
I’ve had questions lately about irrigation termination on soybeans. You are generally safe to terminate irrigation if you have good soil moisture when the seeds fill the pods and the pods start to change to the yellow color in the top 4 nodes of the plant. Mississippi State has a good blog post concerning this subject. Soybean Irrigation Termination
Some full season soybeans will be harvested soon. These warm days will help finish out the season for the Ultra late planted soybeans.

Downy mildew of soybean is being found now in most all the fields I go into at low levels. Downy mildew is easily identified as yellow spots on leaves with a characteristic tuft of fungal growth on the underside of each spot. One may need to look carefully to see the fungal growth, which is typically a grey color.
Dr. Bob Kemerait, UGA Extension Scientist says, “The University of Georgia typically does not recommend spraying fungicides for control of downy mildew because a) the disease is not believed to cause significant yield losses, and b) our fungicides for control of soybean diseases less effective against that type of fungus.”

Ultra late soybeans planted after corn harvest are having foliage feeder problems. This field I was in had many Beet Armyworm (BAW) hatchouts that were eating quite a bit. They looked good otherwise. Grower will soon go in with a herbicide for weeds and volunteer corn. They are watering very often to the the beans growing well as we need good growth on this quick crop.

I looked at 2 blooming soybean fields today, and one had a good hatchout a few days old of juvenile kudzu bugs and the other had some just coming out of the eggs.
The grower chose to spray the one that has many juveniles hatched out. He also has a lot of various caterpillars and some foliage damage so he will piggyback a spray for caterpillars as well or use a combination product that will get both.
It was kind of surprizing that we’re seeing a few Velvet bean caterpillars (VBC), it’s a little early for them. We are seeing several types of caterpillars, mainly fall armyworms, beet armyworms and soybean loopers.
The other grower will wait a few days to make sure most all of this second generation is hatched out so we can get a good kill. He doesn’t have many foliage feeders so he will just go with a pyrethroid for the bugs and some boron.
In this photo below you can see the white egg cases.

We are seeing good numbers of kudzu bugs in soybeans now. Folks are asking what to do.
We don’t need to treat until the second generation in soybeans. In other words we need to wait until we see the young fuzzy nymphs before we treat them. This is usually when we have young pods on the plants.
If you go by a patch of Kudzu, you can see all phases of bugs now, nymphs, eggs and adults. The second generation on Kudzu has moved to soybeans in many fields.
Here’s a link back to a comprehensive Kudzu bug post I made a while back. http://seminolecropnews.wordpress.com/2013/05/30/seeing-more-and-more-kudzu-bugs/

Here’s Jim Dozier in some of his soybeans we recently looked at. They had a few foliage feeders but nothing bad enough to treat.

Soybeans are growing well. Soybeans don’t do well with hot soil so it’s important to have the soil moist before planting.
It’s interesting that thrips are in them like we see in other crops but they don’t affect them nearly as badly.
This field is planted into wheat stubble in 36 inch rows.
Here we have some planted into wheat stubble with a grain drill in 7.5 inch rows.

The Ga Fla Soybean / Small Grain Expo is coming up and it will be in Perry Georgia. Here’s the details.

Ultra late soybeans are turning colors and dropping leaves in many fields. Usually this does happen about the third week in October in deep south Georgia. We were late planting these soybeans after field corn this year and they don’t look as good as usual. Also, the plant stands in some fields aren’t very good. They didn’t get the height that we would like to see but they are full of soybeans.
