    Two similar field day events will be held in NW and SW Ohio. The Soil Health team, part of the OSU Agronomic Crops team, will be hosting a Cover Crop Field Day in Paulding County on Monday, August 16 starting at 6:30 PM. The event will feature speakers Jason Hartschuh, with a topic of Interseeding and Alyssa Essman, with a topic of terminating Cover Crops. The second event will be on Tuesday, August 17th starting at 2:00 PM in Fayette County.

    Paulding County Extension will be hosting two events in Northwest Ohio in August: a soil health tour and a follow-up event with a guest speaker. The soil health tour includes stops around Northwest Ohio showcasing different practices to help improve soil health. A map of tour stops can be found at go.osu.edu/soilhealthtour and will be updated as tour stops are confirmed. The tour stops will be accessible from Friday, August 13th to Thursday, August 19th.

    Fayette County is known for its rich heritage in the agricultural industry. What better place for agricultural organizations such as Ohio State University Extension, Southwest Ohio Corn Growers Association, Fayette County Agronomy Club, Fayette County Chamber of Commerce, Fayette County Agricultural retailers, and the Fayette County Farm Bureau to come together on one day to showcase how important the agriculture industry is to its community.

    We have been screening a random sample of waterhemp populations for herbicide resistance over the past two years.  Herbicides used in the screen include mesotrione, atrazine, 2,4-D, fomesafen, and metolachlor.  Results of our research show that it’s possible for Ohio waterhemp populations to have some level of resistance to one, several, or all of these herbicides.  Glyphosate is not included because we assume almost all populations are already resistant to this.  We are also part of a regional project that has been screening for dicamba and glufosinate resistance with populations that we s

    The month of August provides a window of opportunity for establishing perennial forage stands or filling in seedings made this spring that have gaps. The primary risk with late summer forage seedings is having sufficient moisture for seed germination and plant establishment. The decision to plant or not will have to be made for each individual field, considering soil moisture status and the rainfall forecast. Rainfall and adequate soil moisture in the few weeks immediately after seeding is the primary factor affecting successful establishment.

    While some parts of Ohio have been rather dry this spring and into summer, other areas have been consistently wet throughout.  Either scenario can cause significant problems for grazing and haymaking.  If you are looking for alternative forages to either graze or harvest for hay yet this season, oats in one crop to consider, in part because of its flexibility as a feed, yield potential, and low-cost establishment.  While traditionally planted as the first crop in early April as a grain crop or an early season forage, One of the beauties of oats is its versatility in planting date.

    Cover crops are used for a variety of reasons in a crop rotation. Adding cover crops can improve soil structure, retain nutrients, suppress weeds, reduce water and wind erosion, increase soil organic matter and provide forage. The presence of a cover crop can also influence the amount of nitrogen, phosphorus  and sediment in surface and subsurface water leaving at the edge of field. A summary of cover crops water quality impacts from Ohio field comparisons was recently published.

    Recent concerns and management questions have arisen from equine owners and managers about clover slobbers. One of the causes of excessive salivation in horses is a fungal disease of clover, commonly referred to as “blackpatch”. This pathogen infects legumes (especially clover species) when temperatures exceed 80F with humid/wet conditions, like we have been experiencing in Ohio. Here we are re-running an article about blackpatch  written a number of years ago by Lanny Rhodes, Emeritus Professor of Plant Pathology at OSU.

    Stockpiles of poultry litter can be seen in farm fields across Ohio. While common each year in wheat stubble fields, there are also stockpiles commonly found in soybean fields. Poultry litter is an excellent source of plant nutrients and readily available in most parts of the state.

    Numerous underground oil and gas pipelines have been installed through Ohio farmland over the past several years. This has left many growers wondering if this installation will have lasting impacts on their soils and crops.

    Adult western bean cutworm (WBC) numbers continue to rise for the week ending July 25. Counties currently experiencing high WBC trap counts are primarily located in Northern Ohio (Figure 1). This past week, 11 counties were at the egg mass scouting threshold including: Ashtabula, Defiance, Fulton, Geauga, Henry, Huron, Lake, Lorain, Lucas, Trumbull and Williams. The statewide average for WBC moths also increased, more than doubling from the last week average (6.0) resulting in 14.3 moths per trap. Overall WBC numbers are higher than what we observed in 2020.
