With some crops being replanted in areas where there was hail damage, newly seeded crops are just coming up and susceptible to insect damage. As we move through the summer, older soybeans are also susceptible to insect pests. It is just important to scout fields periodically to monitor new infestations of pests. Also, CropWatch, https://cropwatch.unl.edu/ is a good resource for information on current crop conditions in Nebraska. In southeast Nebraska, we have been subject to isolated infestations of insect pests over the years. More recently the thistle caterpillar, which is the larval stage of the Painted Lady Butterfly. Many people were concerned about the millions of butterflies that invaded us, but it is larval stage which come from the eggs that the butterflies lay that can cause defoliation of soybeans. There were some fields that required treatment in southeast Nebraska. Another pest that showed up was the garden webworm. These types of insects would cause more issues with newly replanted soybeans due to much less foliage. Generally soybeans in the vegetative stage require treatment when defoliation reaches 30%. Here is a link to a graphic reference showing different levels of defoliating; https://cropwatch.unl.edu/soybean-defoliation-7-24-09 . Defoliation usually is not as much as we think it is, so good to have a reference.
