The soybean gall midge, Resseliella maxima (Diptera: Cecidomyiidae), is a relatively new pest in soybean. A recent report showed that soybean gall midge is spreading rapidly, reaching 144 counties by September of 2020, including two western counties in Missouri. Thus far, the soybean gall midge has not been detected in Kentucky.
Read MoreSome years have gone by since I summarized UK research about soybean yield response to sulfur (S) here in Kentucky. The objective of this article is to update my previous summary, a meta-analysis which included research work done between 2007 and 2012, reported in 2013.
Read MoreSeedcorn maggots in corn and soybeans have been seen during cool and damp seasons and organic rich soils (manured can be a source of this) or fields with reduced tillage, or decaying residue from the previous.
Read MoreRainy and cloudy days with soggy and cool nights are favorable for mollusk activity. These conditions describe the past 3 to 4 week’s weather conditions in Kentucky, and the damages these organisms are causing to soybean seedlings.
Read MoreCorn and Soybean planting progress is ahead of schedule in Kentucky, according to the USDA NASS Crop Progress & Condition Reports. We normally think about that being a good occurrence. But many farmers and crop consultants have reported that the corn and soybeans appear to be standing still. The forecast suggests that will change in a few days.
Read MoreSoybean that has emerged is at risk of being frozen off below the cotyledons. If the plants are frozen off below the cotyledons, they will die.
Read MoreThe successful control of waterhemp and Palmer amaranth in soybean has consistently come back to the use of a residual herbicide at soybean planting.
Read MoreThe soybean cyst nematode (SCN) causes greater annual yield losses in Kentucky than any other pathogen of soybean.
Read MoreSoybean cyst nematode (SCN) is the most damaging pathogen of soybean in Kentucky and across the U.S. This pathogen can cause yield losses even though no above-ground symptoms may be apparent. A three-part webinar series conducted by Dr. Kaitlyn Bissonnette (University of Missouri) and Dr. Carl Bradley (University of Kentucky) is coming in February.
Read MoreIn such a turbulent year it is a real pleasure to announce all the records that were set in the 2020 soybean production contest! Congratulations to Ken-Maur Farms in Daviess County for achieving a yield of 106.51 bu/A with AgriGold G3722RX seed.
Read MorePreliminary results from a new on-going SCN survey initiated in 2019 show that 84% of Kentucky fields are infested with SCN.
Read MoreA nice good-looking stink bug was observed in western Kentucky on several occasions during mid-July and mid-August this year. Euthyrhynchus floridanus (Pentatomidae) (Figure 1), known as the Florida predatory stink bug, has been previously detected in Kentucky and several northern states (Ohio, Pennsylvania, Illinois, etc.). This recent occurrence was the first time in nearly 5 years that I have observed this beneficial insect.
Read MoreIn 2020, tallies completed in western Kentucky during the last week of August and first 3 weeks of September resulted in the capture of BMSB in 17 out of 19 counties (Figure 1). Tallies were conducted in 29 commercial soybean fields and three research sites at the REC using sweep nets. This outcome may show a geographical expansion of BMSB colonization of western Kentucky.

Read MoreThis group of insects is especially damaging during the late part of development of soybeans. Adult and immature stink bug stages feed by piercing tender terminals and developing pods causing direct damage to beans. These injuries may cause poor seed formation, aborted seeds, reduced seed size, or seed deformation. Therefore, it reduces yield and quality of beans.
Read MoreAlthough soybean rust has not yet been observed in Kentucky this year, it is likely present in the state. Soybean rust was recently reported in southern Illinois (Union County, IL).
Read MoreSymptoms of sudden death syndrome (SDS) of soybean have begun to appear over the last couple of weeks in Kentucky.
