More wet weather this week (June 10-14)

More wet weather ahead in the forecast makes for tough hay drying weather, and more rain is the last thing we need on some of the wetter ground that we have been waiting to plant all season long. Also, this cool wet weather favors pythium in the soybeans and we have been finding some dead seedlings in several fields across the area.

In the potatoes, the second hilling is getting finished up and fields should be checked for weed escapes. Also, Colorado potato beetles are laying eggs in full force, expect the first generation of larvae to emerge next week. The black light traps are extremely quiet right now with only a few cutworm moths.

Looking forward into the future, consider doing some nematode testing on your farm this year. Nematodes are microscopic worms that exist in almost all soils and, while many are harmless or even beneficial, there are several plant parasitic nematodes that may be secretly robbing yield year after year. Many of you are probably familiar with soybean cyst nematode, but there are many other nematodes that affect other crops. Nematodes that are particularly damaging in corn are dagger, lance, root lesion, and needle.

At Pest Pros, a division of Allied Cooperative, we sample and test soils for nematodes to measure a fields relative risk for nematodes in the future. Such information can help you identify and begin to manage a nematode problem. Sampling can also help you asses your Poncho/Votivo and Avicta programs. For more information on nematode testing, contact the Pest Pros lab at (715) 335-4046.

Watch out for moths

Much of the corn across the area is emerging and some is already at V1 to V2. With the cool spring we have had we are seeing a lot of yellowing in the corn as it emerges. Due to the cold weather, insects have been slow to emerge and migrate in. Not many corn insects have been observed this week. We will be setting up our black light traps later this week to capture and monitor the levels of moths in the area. Key moths we watch out for are European corn borer, corn earworm, black cutworm, various armyworms, stalk borer, and hop vine borer. We monitor these moth counts to better focus our scouting operations on what pests are in the area at what times of the season. Watch out for frost damage later in the week as it is set to get almost to freezing on Thursday across much of our area. Many times the cold air can settle into low parts of the field and do damage.
