Our soybean cyst nematode counts from the fall of 2013 sampling brought us some surprise results. Cyst counts have dropped dramatically from the direction we had seen in the pas years’ samples. This was not just a one field phenomenon but across all fields sampled.
I would like someone to take a shot of explaining this to me. Is it weather related? We have been using PI88788 soybeans for many years on these fields in a corn soybean rotation.
This blog has been rather quiet through the winter. You would think that there’s lots of time to post once in a while but it just seems to fall to the bottom of my list.
Winter started with a bang. All was going well but we still had one more job to do, pull soil samples in the corn ground to test for soybean cyst nematodes. Sounds simple enough but not when you have an impending snow breathing down your neck. November 5, 2013 was the beginning of the end of our nice fall weather. Samples were pulled on three fields and as snow began to fall we scrambled to get the most critical areas sampled of the last field.
By the time the fourth and final sample was pulled, we already had 1″ of snow on the ground and it was coming down heavy and wet. One of the soil probes gave up working in these conditions. We woke up the next morning to this. Fall was officially over.
As we work our way through harvest, one of the events we look forward to is harvesting our corn test plot. A lot of time and thought go into choosing hybrids for this plot. This plot is an extremely vital part of our operation’s decision making process for the next year’s corn varieties.
Because our operation focuses heavily on corn varieties that use hybrids with less insect traits than the companies are pushing, there is little plot data available to help us make decisions on these hybrids. This is a part of our broad plan to deal with corn insect resistance issues. Continue reading
The 2013 harvest began this week. Not as unusual as it used to be, we started harvest with corn instead of soybeans. The corn stalks are quite weak this year from drought stress driving us to fire up the corn dryer and get moving taking the weakest corn first. Not all corn is created equal and some is falling before we can harvest it.
We tried harvesting the variety that was the worst but the kernels would not come off the cob so it waits longer and falls more.
We prefer to dry corn rather than let it naturally dry in the field. This saves us from phantom losses as well as over dry kernels shelling off in the corn head and dropping in the field.
The combine is out of the shed, the heads are ready, the grain system is ready and very soon the crops will be ready to harvest. A few neighbors have started to take out both corn and soybeans. At last check our corn was too wet and beans are a few days away as well.
The time has come to do our post-emerge application of Roundup on our soybeans. This spring we used a pre-emerge herbicide on our our fields. The soybean fields looked so clean we delayed longer than usual with our post emerge application. When we started spraying we realized the mistake we had made. The remaining weeds were 1 foot or taller. Too large for Roundup to do significant damage to. Many will burn down and then come back. Scouting the field one week later we already saw signs of new growth on waterhemp that looked dead from a distance. We also found 1 1/2 foot tall waterhemp than had little or no damage to the plant from our Roundup application of 38oz/acre.
On two fields we chose to take more drastic measure and hired migrant workers to hoe out our resistant weeds. They showed up two weeks after spraying and spent a few days walking the fields.
We also dug our old bean rider out of the shed and did some field border spraying from that.
Not to leave any weed patches untouched, we finally brought out our own hoes and went after some stray weeds with them.
