Good afternoon,

The Hardin Field Day was a success with about 190 people in attendance.  There were several speakers for attendees to hear over a wide range of topics that were related to the theme ‘Agriculture Conservation- Protecting Water: Keeping Soil and Nutrients in the Field.’  Although we had perfect weather for the day, the recent rains made the field too wet to do field demonstrations.  However, there were several conservation and water quality structures and equipment for people to see.  To read a recap of the event, see the attached reminder article that was written by Hardin SWCD’s Kathy Bash.

 Agriculture Conservation News Release

This Wednesday (8/31) will be the Ohio No-Till Field Day in Hardin County as well.  Jan Layman’s farm (15238 Twp. Rd.119 – Kenton) will be the host site for this year’s statewide field event.  Registration will begin at 8:00, with a $60 on-site registration fee for those who didn’t pre-register for $40.  Dave Brandt, president of the Ohio No-Till Council will give the welcome at 8:45 am, followed by a host of presenters and field demonstrations.  There will also be a cover crops plot along with a soil pit, demonstrating water infiltration.  Soil health will be a key theme of this field day, as described both in the article below and the attached article taken from the Ohio No-Till News.  This field day rotates around the state, so you won’t want to miss it while it is in our backyard.

Bt Resistance in Western Corn Rootworm—The 3rd Shoe Has Dropped – Andy Michel, Kelley Tilmon

Western corn rootworm is a highly adaptable insect, and it was just a matter of time before we saw resistance to Bt traits designed to protect against root damage.  In the Western Corn Belt, growers have noticed many field failures due to heavy rootworm feeding. Most of this research was led by Dr. Aaron Gassmann’s laboratory at Iowa State University.  In 2011 they discovered resistance to Cry3Bb1 (which may be present in Yieldgard or Genuity traits). In 2014 they discovered resistance to mCry3A (which may be present in Agrisure traits).  Now, in 2016, they have discovered resistance to Cry34/35Ab1 (which may be present in Herculex or Optimum traits).

Late season diseases are making their appearance – Anne Dorrance

Sudden death syndrome.  I was scouting the sudden death syndrome study and symptoms have started.  And due to the calls I am getting it is also in some producer’s fields.  Sudden death syndrome (SDS) is a fungal disease of soybean and is limited to a few locations in Ohio.  Interestingly, these fields where SDS occurs in Ohio, also have high SCN populations.  To read more about Sudden death syndrome, White mold or Sclerotinia stem rot, Diaporthe Stem canker, and Phytophthora stem rot in soybean, go to http://agcrops.osu.edu/newsletter/corn-newsletter/late-season-diseases-are-making-their-appearance. 

 

Ohio No-Till Field Day – August 31 – Mark Badertscher

Are you thinking about switching to no-till and have some questions you need answered before taking the leap?  Maybe you‘ve been planting no-till soybeans for years and are thinking about adapting this practice to corn.  Adopting no-till requires understanding how it affects drainage, soil structure, organic matter, weed control, and the application of pesticides and chemical fertilizers, all of which influence both yields and environmental impacts.  For more information about this field day being held in Hardin County, go to http://agcrops.osu.edu/newsletter/corn-newsletter/2016-26/ohio-no-till-field-day-august-31.

 

Contract Termination – The Big Data Confusion: Part 12 – John Fulton, Kaylee Port

Termination signifies ending an obligation under a contract. Sometimes, terminating a contract can be a difficult process. Verbiage used within a contract about terminating can vary as it relates to the ability of the customer to cancel the contract or services being provided.  One should take the time to read contracts or agreements specific to termination and what it means to you as a user but also the company or agency, if you decide to cancel.  The 11th principle of the American Farm Bureau Federation’s “Privacy and Security Principles for Farm Data” includes Contract Termination stating that “farmers should be allowed to discontinue a service or halt the collection of data at any time subject to appropriate ongoing obligations. Procedures for termination of services should be clearly defined in the contract.”  Go to http://agcrops.osu.edu/newsletter/corn-newsletter/contract-termination-big-data-confusion-part-12 to finish reading this article.

 

Potential for Nitrate Problems in Drought Stressed Corn – Peter Thomison, Laura Lindsey

Have very dry soil conditions increased the potential for toxic levels of nitrates in corn harvested for silage? Nitrates absorbed from the soil by plant roots are normally incorporated into plant tissue as amino acids, proteins and other nitrogenous compounds. Thus, the concentration of nitrate in the plant is usually low. The primary site for converting nitrates to these products is in growing green leaves. Under unfavorable growing conditions, especially drought, this conversion process is retarded, causing nitrate to accumulate in the stalks, stems and other conductive tissue. The highest concentration of nitrates is in the lower part of the stalk or stem. For example, the bulk of the nitrate in a drought-stricken corn plant can be found in the bottom third of the stalk. If moisture conditions improve, the conversion process accelerates and within a few days nitrate levels in the plant returns to normal. Go to http://agcrops.osu.edu/newsletter/corn-newsletter/potential-nitrate-problems-drought-stressed-corn to read more about this potential issue.

August 20, 2016

Good evening,

This coming week is a big week in Hardin County for agriculture.  Monday (8/22), farmers will be able to dispose of unwanted pesticides (herbicides, insecticides, fungicides, etc) at the fairgrounds from 9:00 am – 3:00 pm as part of the Ohio Department of Agriculture Clean Sweep program.  We are fortunate to have this free service available in our county this year.  I was told by ODA that the largest container that can be accepted is a 55 gallon drum.  So, if you have mini-bulks or totes that are larger, you need to put the chemicals into smaller containers for transport by the contractor.  See the article below for more information about this opportunity to dispose of unwanted pesticides.

Tuesday (8/23) evening at 7:00 pm will be our second Twilight Tour.  This field event will take place at one of our OSU Extension Nitrogen Timing plots at 6000 County Road 110, Alger.  Paul Ralston will be discussing his use of Y-drops to apply late season nitrogen on his corn crop, and his sprayer with these attachments will be on display.  This particular plot had 20 gallons of 28% N applied in strips at V6, V8, V10, and VT.  One strip in the plot had 0 gallons applied.  These treatments were replicated three times across the plot.  There will also be a demonstration of the 360 Soil Scan testing system to instantly check nitrate and pH levels in the soil, as well as information about the field received from aerial imagery.  For more information about this program, see the attached flyer.

MRI Late Season Nitrogen Twilight Tours Flyer

The Hardin Field Day, Agricultural Conservation – Protecting Water: Keeping Soil & Nutrients in the Field will be this Friday (8/26) in Chris Kurt’s field on the corner of US 68 and County Road 50, one mile south of Dunkirk.  Several partners have been planning this event for months, and we believe that you will be amazed with the work that Hardin County farmers are doing to protect the water and soil through the efforts demonstrated and shared during this field day.  We have several presenters from all over Ohio and Indiana, including The Ohio State University’s Stone Laboratory on Lake Erie and the Toledo Collins Park Water Treatment Plant.  See the attached flyer for more details about the day, which begins with registration at 8:30 am.

Hardin County Field Day Flyer

Next week the Ohio No-Till Field Day will take place August 31 at Jan Layman’s farm.  This event is also jam packed with very informative presenters and field demonstrations, so you won’t want to miss it either.  To read more about this field day, see the news article that I attached to this email.  Even though we have been receiving rainfall this past week, the drought conditions of our recent past are not removed from our memory.  During the month of July, Extension rainfall reporters recorded an average of 1.68 inches of rain in Hardin County.  You might be interested in taking a look back at July’s Extension rainfall report summary that it is included with this week’s Hardin County Agriculture and Natural Resources Update.

SPRAYING INSECTICIDES ON SOYBEANS AND HONEY BEES – Andy Michel, Reed Johnson

Although soybean aphids remain at low levels in Ohio, we are aware that many growers are adding insecticides to spray tanks when applying fungicides for plant health purposes and even late applications of herbicides because: “Well, I’m going over the field anyway so I thought I’d add an insecticide for insurance purposes!  The insecticide is relatively cheap and soybeans are worth so much!”  As we have always stated, we do NOT recommend this practice, and feel an IPM approach is much better for everyone and everything, including the environment.  We do NOT recommend an insecticide application unless there is a REAL need.  Go to http://agcrops.osu.edu/newsletter/corn-newsletter/spraying-insecticides-soybeans-and-honey-bees to continue reading this article.

 

 

 

 

 

WARM NIGHTS MAY IMPACT CORN YIELD – Peter Thomison

Weathercasters are calling for continued above average temperatures in August, especially higher night time temperatures.  Past studies show that night time temperatures affect yield potential.  High night temperatures (in the 70s or 80s degrees F) can result in wasteful respiration and a lower net amount of dry matter accumulation in plants.  The rate of respiration of plants increases rapidly as the temperature increases, approximately doubling for each 13 degree F increase.  With high night temperatures more of the sugars produced by photosynthesis during the day are lost; less is available to fill developing kernels, thereby lowering potential grain yield.  High night time temperatures result in faster heat unit (GDD) accumulation that can lead to earlier corn maturation, whereas cool night temperatures result in slower GDD accumulation that can lengthen grain filling and promote greater dry matter accumulation and grain yields.  To finish reading this article, go to http://agcrops.osu.edu/newsletter/corn-newsletter/warm-nights-may-impact-corn-yield.

 

 

 

 

 

PESTICIDE DISPOSAL COLLECTION DAYS – Mark Badertscher

Do you have pesticides sitting in storage that you do not intend to use?  The Ohio Department of Agriculture will be sponsoring four Ohio Pesticide Clean Sweep Days around the state for farmers wishing to dispose of unwanted pesticides on four different dates in August.  The pesticide collection and disposal service is free of charge, but only farm chemicals will be accepted.  Paint, antifreeze, solvents, and household or non-farm pesticides will not be accepted.  The disposals are limited to farmers only.  Commercial entities are not supposed to bring product.  Pesticides do not have to be in original containers or identifiable for disposal.  The largest container that can be accepted is a 55 gallon drum as long as it has a good sealed bung.  There is no limit to the amount of pesticides that a farmer can bring, although ODA would like to know if someone is bringing anything larger than a pickup load.  To read more, go to http://agcrops.osu.edu/newsletter/corn-newsletter/pesticide-disposal-collection-days.

 

 

 

 

 

SCREENING CONSERVATION COVER SEED FOR THE PRESENCE OF PALMER AMARANTH – BE INFORMED BEFORE YOU PLANT – Mark Loux

The three primary sources of new Palmer amaranth infestations in Ohio so far have been:  1) presence of Palmer seed in the cotton-based feeds that are brought here from the south; 2) movement of contaminated combines from Palmer-infested areas of the south to Ohio; and 3) presence of Palmer seed in seed for conservation plantings (cover crop/CRP/wildlife/pollinator), which comes from states farther west such as Texas and Kansas.  The latter mechanism has gained some notoriety lately in Iowa, where Palmer amaranth was found in conservation plantings in four counties due to the planting of a likely contaminated seed mix.  We currently know of at least two sites here in Ohio where Palmer was introduced this way, one of which resulted in the contamination of several large fields along the Scioto river, and the other where the producer chose to destroy an extensive new conservation planting rather than risk spread to his crop fields.  Go to http://agcrops.osu.edu/newsletter/corn-newsletter/screening-conservation-cover-seed-presence-palmer-amaranth-be-informed to find out how to get this seed tested for free before planting.

 

 

 

 

 

 

 

 

FERTILIZER APPLICATOR CERTIFICATION & TRAINING – Jeff Stachler

A three-hour fertilizer applicator certification training program will be held by The Ohio State University Extension on Monday, August 29, from 6:30 to 9:30 PM at the Palazzo in Botkins, Ohio.  Refreshments will be served at 6:00 PM.  Topics that will be discussed include the current status of water quality, soil sampling, and phosphorus and nitrogen management.  Anyone involved in agricultural production and applying fertilizer to greater than 50 acres must obtain this certification prior to September 30, 2017.  After this date, a test could be required to obtain this certification.  This program is specifically for those individuals not having a pesticide license, although those having a pesticide license may also attend.  Agricultural Professionals please help in reminding your clientele about this fertilizer applicator certification and training program.  Thanks to TruPointe for sponsoring location and refreshments.  Pre-register for the meeting prior to August 26, 2016 by calling the Auglaize County Extension office at 419-739-6580.

Hello,


It rained!  This past weekend brought much needed rainfall to Hardin County and surrounding areas.  How much the dry conditions have stunted the crops and will have an effect on yields is another question for another day.  Hopefully the soybeans will adjust and the corn crop that was under stress will improve from this point forward.  As mentioned in last week
s Hardin County Agriculture and Natural Resources Update, there are two Twilight Tours coming up the next two Tuesdays.  Tuesday, August 16 we will be meeting at Ted Griffiths field located at 6551 State Route 701, Ada starting at 7:00 pm.  This program will discuss the Modified Relay Intercropping of soybeans into 15 inch row wheat.  Ted will also have his modified drill on hand to see, and OSU Extension will have similar on-farm and plot research data available to share with the participants.  August 23 will be the second Twilight Tour of the series, with the subject being Late Season Application of Nitrogen to Corn
.  See the attached news release and flyer for more details.  We hope to see you there.

WESTERN BEAN CUTWORM UPDATE
– Kelley Tilmon, Andy Michel
On another note, adult western bean cutworm trap counts are declining, having past their peak for the summer.  But scouting is still relevant as the later moths continue to lay their eggs.  Counties near Lake Erie have had particularly high trap counts.  Threshold populations on corn plants should be treated before larvae have a chance to enter the plants. To scout for eggs or larvae, choose at least 20 consecutive plants in 5 random locations and inspect the uppermost 34 leaves for eggs, as well as the silks for larvae if tassel has emerged. Be sure to inspect different areas of the field that may be in different growth stages. For field corn, if 8% or more of the plants inspected have eggs or larvae, consider treatment. For sweet corn, consider treatment if eggs or larvae are found on >4% of plants for the processing market or on >1% of plants for fresh-market.  Find more information at:

2016 OHIO WHEAT PERFORMANCE TEST AVAILABLE ONLINE – Laura Lindsey, Matthew Hankinson
A pdf of the 2016 Ohio Wheat Performance Test can be found at the Soybean and Small Grain website at: 
http://stepupsoy.osu.edu/node/35.   A sortable version of the Ohio Wheat Performance Test can be found at: http://www.oardc.ohio-state.edu/wheattrials/.  Test results are for 72 soft red winter wheat varieties grown at five Ohio locations (Wood, Crawford, Wayne, Darke, and Pickaway County).  Variety selection should be based on disease resistance, average yield across test sites and years, winter hardiness, test weight, and standability. Overall, grain test weight averaged 58.4 lb/bu (compared to an average test weight of 56.3 lb/bu in 2015). Grain yield averaged between 97 and 119 bu/acre at the five locations.

 

TASSEL EARS SIGHTINGS IN CORN – Peter Thomison

Tassel Ears are showing up in corn fields around Ohio. Corn is the only major field crop characterized by separate male and female flowering structures, the tassel and ear, respectively. In most corn fields it is not unusual to find a few scattered plants with a combination tassel and ear in the same structure – a “tassel ear”. The ear portion of this tassel ear structure usually contains only a limited number of kernels.  For more information on tassel ears, go to http://agcrops.osu.edu/newsletter/corn-newsletter/tassel-ears-sightings-corn.

Good afternoon,

The story of the week is that Hardin County is still in need of rain.  If you look at the latest U.S. Drought Monitor website at http://droughtmonitor.unl.edu/Home/StateDroughtMonitor.aspx?OH, you will see that most of the county is now considered in ‘Moderate Drought’ as of August 2.  Checking crops around the county, more and more corn fields are showing stress during this critical time of kernel development.  Although the northern part of the county seems drier, parts of southern Hardin County are very dry as well.  The interesting part about the corn stress, is that some fields are showing it more than others, even on the same road where rainfall was the same.  This could be the result of drought resistant hybrids, soil type, drainage, tillage, planting date, root development or a combination of more than one factor.  Soybeans are beginning to show evidence of the dry weather as well with some fields having spider mites.  Soybean plants are shorter than usual and some have fewer and smaller pods at the nodes.

If you are a fruit and vegetable grower, don’t forget that tomorrow evening, Tuesday, August 9 is the Hardin County Crop Walk program starting at 6:00 pm at Levi Yoder’s farm (15460 County Road 209) southeast of Kenton.  See the attached article for more information about this event that will feature OSU Extension Horticulturist Jim Jasinski and OSU-OARDC Plant Pathologist Dr. Sally Miller.  I have also included a flyer and news article about this year’s Hardin Field Day, ‘Agricultural Conservation, Protecting Water: Keeping Soil and Nutrients in the Field.’  This is the second year for this field day, cooperatively sponsored by the following partners: The Nature Conservancy, John Deere, Findlay Implement, Chris Kurt, Randy Boose, OSU Extension, Hardin & Putnam Soil and Water Conservation Districts, Ohio Farm Bureau/Blanchard River Demonstration Farms Network, Ohio Department of Agriculture and USDA Natural Resources Conservation Service.  It will take place on August 26 and requires participants to pre-register to ensure a lunch count for the event.  Please call the Hardin Soil and Water Conservation District at 419-673-0456, extension 3 by August 17 to attend this free event.

Insect Pests we’re Watching Now – Kelley Tilmon, Andy Michel

With continued dry weather, spider mites are one of the main pests to remain vigilant about in field crops.  They will often show up in field borders first as they move in from other habitats, for example if nearby ditches have been mowed.  Spider mites are difficult to see.  Look for injury signs — yellow spotting or stippling on the upper side of leaves.  In soybean this damage usually begins in the lower canopy and progresses upward as the mite population increases.  Heavily infested leaves may also have light webbing similar to spider webs.  Go to http://agcrops.osu.edu/newsletter/corn-newsletter/insect-pests-we%E2%80%99re-watching-now to read more about Spider Mites, Western Bean Cutworm, Grasshoppers, Japanese Beetles, and other Soybean Defoliators.

 

Developing a Plan to Keep Nutrients in the Field – Greg LaBarge

Nutrient Management Plans provide both fertility recommendations for crop production and an environmental site risk for on a field by field basis that help identify resource concerns impacting nutrient and sediment loss. The process helps identify fields with a higher risk profile and appropriate Best Management Practices that can limit losses. For water quality related to agricultural production, the impact of sediment and nutrients primarily phosphorus and nitrogen are the greatest concerns.  To learn more about nutrient management plans and how you can get one for your farm, go to http://agcrops.osu.edu/newsletter/corn-newsletter/developing-plan-keep-nutrients-field.

 

Hot, Dry Conditions Stressing Corn – Peter Thomison

Throughout Ohio, especially northern Ohio, there are corn fields exhibiting drought and temperature stress. Leaf rolling is common and uneven, stunted corn growth is widespread. Moreover, most of these stressed corn fields are now beyond the stage of development that is especially susceptible to drought and high temperature injury – pollination.  High temperature stress is usually associated with drought.  Heat stress and drought intensify damage to corn and soybean but either may cause major crop injury alone.  To read more, go to http://agcrops.osu.edu/newsletter/corn-newsletter/hot-dry-conditions-stressing-corn.

 

Got waterhemp? – Find Out the Herbicide Resistance Characteristics Now – Mark Loux

We have spent a lot of time educating and warning about Palmer amaranth, but while we were doing this, waterhemp has become a more widespread problem.  Waterhemp is only a little less fun to deal with than Palmer amaranth, and has a tendency to fairly rapidly develop resistance to any new sites of action used repeatedly against it in POST treatments.  Submitted questions and photos to confirm identification of this weed increased substantially this summer over previous years.  Waterhemp infestations can be found around the state, with a concentration in west central Ohio.  To finish reading this article about waterhemp, go to http://agcrops.osu.edu/newsletter/corn-newsletter/got-waterhemp-%E2%80%93-find-out-herbicide-resistance-characteristics-now.

 

Data Retention and Availability –The Big Data Confusion: Part 11 – John Fulton, Kaylee Port

Data retention policies represent a set of guidelines that outlines data will be archived, how long it will be kept, how it will be removed, and either destructed or returned to the farmer.  The American Farm Bureau Federation’s “Privacy and Security Principles for Farm Data” includes the principle of Data Retention and Availability stating that “Each ATP (Ag Technology Provider) should provide for the removal, secure destruction and return of original farm data from the farmer’s account upon the request of the farmer or after a pre-agreed period of time.  To read more on this series, go to http://agcrops.osu.edu/newsletter/corn-newsletter/data-retention-and-availability-%E2%80%93-big-data-confusion-part-11.
