The disease tar spot, caused by the fungus Phyllachora maydis, was first discovered in the United States in 2015. Since 2015, tar spot has become a major corn disease in the Midwest, causing yield losses up to 60 bushels per acre in fields where it is established. The disease was confirmed via laboratory diagnosis in two counties in Kentucky in 2021. While the impact of tar spot in Kentucky is not yet known, Kentucky farmers are concerned about the disease and potential for yield loss. Confirmin

As reported earlier, 46 Todd County soybean fields in the fall of 2021 to determine the level of soybean cyst nematode (SCN) activity. The results of those tests were reported in terms of the number of nematode eggs per 100 cubic centimeters of soil. Based upon those egg numbers, the fields were evaluated for the odds of SCN related yield reductions. The 46 fields sampled belonged to 33 different producers.After the results from the tests were received in January, I personally
This year, plant pathology specialist Dr. Carl Bradley requested soil samples from Kentucky soybean fields to survey for plant-parasitic nematodes (other than soybean cyst nematodes (SCN)) that can negatively affect soybean yields. Dr. Bradley also promoted the opportunity to test fields for SCN through a program where the Kentucky Soybean Association would pay the laboratory analysis fees. Taking advantage of these opportunities, I sampled 46 producer fields for soybean cyst nematod
