We finally received a nice rain shower but could use more rain to help with corn pollination and soybean growth. During the month of July, Extension rainfall reporters recorded an average of 3.96 inches of rain in Hardin County. Last year, the average rainfall for July was 3.76 inches. Although adequate rain has been received this year during July, some townships have had much more while others have received considerably less. This has caused crops in some areas to need more rain at a crucial time during the growing season. Read more about Hardin County township rainfall and its effect on crops in the attached July 2019 Rainfall Summary. Statewide, 71% of the corn is silking and 69% of the soybeans are blooming according to the August 12 Ohio Crop Weather Report. I have attached this report along with the previous week’s report for August 5.
The Ohio August 1 Crop Forecast has Ohio’s projected corn yield at 160 bushels per acre and soybean crop at 48 bushels per acre. Wheat yield was estimated at 61 bushels per acre. This attached report does mention that Ohio growers will harvest 710,000 fewer acres of corn and 810,000 fewer acres of soybeans in 2019 as compared to 2018. That is in line with a report that came out last night with Hardin County having 91,389 prevented planting acres out there, which ranks it second only to Wood County in Ohio with 120,480 acres not planted. Other area counties in the top ten for prevented planting were Hancock with 74,169 and Wyandot with 53,860 acres not planted.
Don’t forget that there is an “Essentials in Financial Risk Management” workshop with dinner coming up August 20 at Mid-Ohio Energy in Kenton at 6:00 pm. See the attached flyer for details about how to register for this event sponsored by Nationwide Insurance, Hardin and Wyandot County Farm Bureaus, Ag Credit, and OSU. I have also included a Michigan State University Extension Fact Sheet on Stress to this email which includes strategies of dealing with this condition. Another event coming up locally is the Monarch Butterflies workshop being hosted by the OSU Extension Hardin County Master Gardener Volunteers on Saturday, August 17 starting at 9:00 am at the Friendship Gardens of Hardin County located in Kenton. See the attached news release and flyer for more details about this program. Other local events include the Soil and Water Conservation District meeting Thursday (8/15) starting at 1:00 pm at the fairgrounds shelter house and the SWCD annual meeting and customer appreciation event Thursday (8/15) starting at 5:00 pm at the fairgrounds shelter house. The Hardin County Fair work day is scheduled for Saturday (8/17) starting at 8:30 am at the fairgrounds. The Cattle Producers picnic is August 24 starting at 6:00 pm in the Community Building at the fairgrounds. I hope you have the time to read the ag crops articles that I have included below.
Delayed Corn Planting the Disease Risk in Corn – Pierce Paul
In Ohio, several foliar diseases are of greater concern in late-planted corn for a number of reasons, including: 1 – for diseases like gray leaf spot (GLS), northern corn leaf blight (NCLB), and eye spot that are caused by pathogens that overwinter in corn stubble, delayed planting allows more time for inoculum (spores) to buildup, especially in no-till, corn-on-corn fields and 2 – for diseases like common and southern rust that are caused by pathogens that do not overwinter in Ohio, planting late allows more time for spore for blow up from southern states. So, with late planting, not only are more spores likely to be available to infect the crop, they are also more likely to infect the crop at an earlier growth stage and under conditions that are more favorable for disease development. Make sure you scout for these diseases if the hybrid is susceptible and conditions become favorable as described at https://agcrops.osu.edu/newsletter/corn-newsletter/2019-23/delayed-corn-planting-disease-risk-corn.
Are Crops Catching Up? – Laura Lindsey, Peter Thomison
Corn. Crop development varies tremendously across Ohio because of planting dates that range from late April to early July. According to field agronomists in some areas of the state, it looks like late-planted crops are “rushing through development” …Unlike soybean, corn development is directly related to temperature, i.e. heat unit accumulation. Above average July temperatures (especially nighttime temperatures) have promoted rapid corn growth and development. After corn reaches the V10 stage (and most of our June plantings are near or beyond this stage), leaf collar emergence occurs at approximately one leaf every 50 GDDs. Late planted corn fields (especially those that have adequate soil moisture and good soil fertility and weed control) may appear to be “catching up” with neighboring fields planted earlier. The rapid growth of late planted corn is associated with greater vegetative growth and faster canopy closure, which will help optimize yields. However, it does not mean that the rate of development of later plantings is greater than earlier plantings.

Drought and Heat Stress – Peter Thomison
One of the corn production scenarios agronomists least like is an exceptionally wet spring followed by a hotter and drier than normal July and August. The spring of 2019 was one the wettest on records throughout much of the state and now, as the dry weather that started in July persists, such a scenario seems to be a possibility in many Ohio corn fields. A combination of warm temperatures and inadequate rainfall is beginning to stress corn fields across Ohio. What’s exacerbating this problem are the marginal roots evident in some corn fields. Several factors, including poor planting conditions, surface/sidewall compaction and/or excessively wet soil conditions in June have inhibited good root development in many fields.

2019 Ohio Wheat Performance Test – Laura Lindsey, Matthew Hankinson
Yield results from the 2019 Ohio Wheat Performance Test are online at: https://www.oardc.ohio-state.edu/wheattrials/default.asp?year=2019 Disease information will be available soon. The purpose of the Ohio Wheat Performance Test is to evaluate wheat varieties, blends, brands, and breeding lines for yield, grain quality, and other important performance characteristics. This information gives wheat producers comparative information for selecting the varieties best suited for their production system and market. Varieties differ in yield potential, winter hardiness, maturity, standability, disease and insect resistance, and other agronomic characteristics. Selection should be based on performance from multiple test sites and years.

“Working Lands” Forage Field Days Planned – Garth Ruff
The Ohio Department of Agriculture Working Lands Buffer Program allows for forage to be grown and harvested from field edge buffers in the Western Lake Erie Basin. Join OSU Extension, Ohio Forage and Grassland Council, and your local Soil and Water Conservations Districts to learn about the Working Lands Program. Topics to be covered at these field days include: Soil Fertility ~ Seed Bed Preparation ~ Forage Species Selection ~ Seeding Methods ~ and More!
Field Days will be held at various locations throughout the Western Basin watershed including Hancock County: August 22 at 4:00 pm – 19178 Twp Rd 65 Jenera. Gary Wilson 419-348-3500. Find out more at https://agcrops.osu.edu/newsletter/corn-newsletter/2019-25/working-lands-forage-field-days-planned.
