Conditions the past couple weeks were generally favorable for fieldwork. Growers kept busy applying herbicides and fungicides, hauling manure, harvesting hay, tilling fields, and planting cover crops. See the attached August 19 Ohio Crop Weather Report for additional information. Parts of Hardin County received much needed rains to help the corn, soybean, and hay crops. I have included a news release about the dry weather stress and how it affects the corn crop which was written by Hancock County OSU Extension Educator Ed Lentz. The OSU The Ag Safety and Health program has a grain dust research study to quantify the amount of dust present inside on-farm storage bins during load-out periods, and specifically when workers are using sweep augers and actively cleaning the bin. They are seeking farms that will allow dust samples to be collected from their bins during the load out periods. The farm will receive a dust analysis report approximately 1 week later. In the report, the results will show the amount of Total Dust and Respirable Dust present in the environment. The program will provide an N-95 respirator for all workers – upon request at the scene. See the attached document if you are interested in participating in this OSU Grain Dust study. Also, OSU Ag Engineers want information from a wide range of folks, including those who do not have residue managers on a planter. They have a survey they would like farmers to complete regarding planter residue management. You can participate in this survey at https://osu.az1.qualtrics.com/jfe/form/SV_6iquxSX5KmnuzeB.

The Farm Science Review is coming up September 17-19 at Molly Caren Agricultural Center in London. Each year over 100,000 people gather for this annual farm show with over 700 exhibitors and over 100 acres of exhibits. Engage with a diverse group of experts in the agricultural industry, explore over 4000 product lines and services to help enrich your future in agriculture. If you are interested in attending this year’s FSR, we have tickets available at the Extension office for $7 each through Monday, September 16. Each ticket we sell keeps $1 in Hardin County to benefit Hardin County AgNR Extension programs. If you are interested in visiting sheep farms and learning more about this livestock industry in Ohio, OSU Extension is organizing the annual Hardin County Sheep Management Tour for September 14-15 in cooperation with the Hardin County Sheep Improvement Association. This year our group is touring farms and industry visits in Ashland and Wayne Counties. See the attached letter for more information.
Have you seen any evidence of bagworms in your trees or shrubs? I have been receiving calls about this insect pest and have provided an article about them attached to this email. There’s not a lot you can do about them this time of year short of hand removing them, so read the article to learn more about your options. Are you a gardener interested in becoming and OSU Extension Master Gardener Volunteer? Logan County and Champaign County Extension are offering a daytime MGV training course this fall in West Liberty where you could get trained and then volunteer in Hardin County. See the attached flyer for details. Do you have unused pesticides that you need to dispose of safely? There will be a Clean Sweep pesticide disposal program do properly dispose of them in Miami County as indicated below on August 29. Household or non-farm pesticides will not be accepted. For more details and information about a later location in Wayne County, go to https://www.agri.ohio.gov/wps/portal/gov/oda/divisions/plant-health/news-and-events/.
|August 29||Miami County||Miami County Fairgrounds (North end), 650 N County Rd. 25 A, Troy, Ohio 45373||9:00 am – 3:00 pm|
Pesticide Disposal Day
Other events in our region include an Upland Wildlife Habitat Management Workshop in Auglaize County August 27; Cattlemen’s Fall Roundup in Shelby County September 3; Cover Crops and Soil Health workshop in Logan County September 5. Check the attached flyers for more information about these events. Local events coming up include a Fairboard meeting Wednesday, August 28 starting at 7:00 pm in the Community Building at the fairgrounds and the Hardin County Fair September 3-8. This week’s attached farm stress fact sheet is about “How to Cultivate a Productive Mindset.” I hope you are staying positive and productive. See the ag crops articles below for further reading.
Corn Earworm in Field Corn; Watch for Molds – Kelley Tilmon, Pierce Paul, Andy Michel
There have been recent reports of high corn earworm populations in certain grain corn fields. Corn earworm is a pest with many hosts including corn, tomatoes and certain legumes. In Ohio it is typically considered a pest of sweet corn rather than field corn, but this past week substantial populations have been found in certain field corn sites. Corn earworm moths are most attracted to fields in the early green silk stage as a place to lay their eggs. These eggs hatch into the caterpillars that cause ear-feeding damage, open the ear to molds, and attract birds. With a wide range of planting dates this year, different fields may be at greater risk at different times.

Frogeye Leaf Spot – Is It Worth Spraying in 2019? – Anne Dorrance
Several reports over the last two weeks of heavy frogeye leaf spot pressure in some fields as well as low to moderate pressure in others. This disease will continue to increase and infect new foliage as it develops on these late planted soybeans. Based on our previous research, only once (2018) in 14 years of studies did applications at the soybean growth stage R5 contribute to preserved yield. At the R5, the leaf at the terminal is fully developed and the pods at any one of the top four nodes is fully expanded, but the seeds are just beginning to expand. Soybeans that have frogeye and have just begun to flower, are at full flower, or have just reached the R3 growth stage, these decisions are going to be challenging. In full disclosure, we don’t have data or examples to rely on here. This late planting and late development is all new territory for all of us. But there are some sound principles to rely on.

Estimating Yield Losses in Stressed Corn Fields – Peter Thomison
Many corn fields are still silking (and some are just past the mid-vegetative stages)….so, it may seem a little early to discuss estimating grain yields. However, according to the most recent NASS crop report, for the week ending Aug. 8, 2019, 25% of the corn crop has reached the dough stage (compared to 63% for the 5 year average). Corn growers with drought damaged fields and late plantings may want to estimate grain yields prior to harvest in order to help with marketing and harvest plans. Two procedures that are widely used for estimating corn grain yields prior to harvest are the YIELD COMPONENT METHOD (also referred to as the “slide rule” or corn yield calculator) and the EAR WEIGHT METHOD. Each method will often produce yield estimates that are within 20 bu/ac of actual yield. Such estimates can be helpful for general planning purposes. Finish reading this article at https://agcrops.osu.edu/newsletter/corn-newsletter/2019-26/estimating-yield-losses-stressed-corn-fields to learn how to calculate corn yield estimates in the field.
Poultry Litter Applications – Glen Arnold
Stockpiles of poultry litter can be seen in farm fields across Ohio. While common each year in wheat stubble fields, there are also stockpiles showing up in prevented planting fields. Poultry litter is an excellent source of plant nutrients and readily available in most parts of the state. Poultry litter can be from laying hens, pullets, broilers, finished turkeys, turkey hens, or poults. Most of the poultry litter in the state comes from laying hens and turkey finishers. Typical nutrient ranges in poultry litter can be from 45 to 57 pounds of nitrogen, 45 to 70 pounds of P2O5, and 45 to 55 pounds of K2O per ton. The typical application rate is two tons per acre which fits nicely with the P2O5 needs of a two-year corn/soybean rotation. Like all manures, the moisture content of the poultry litter greatly influences the amount of nutrients per ton. Handlers of poultry litter have manure analysis sheets indicating the nutrient content. Go to https://agcrops.osu.edu/newsletter/corn-newsletter/2019-26/poultry-litter-applications to find out more about poultry litter and its regulations.
