Good evening,

Another week has passed and our Hardin County online rainfall reporters (www.cocorahs.org) have collected an average of 1.55 more inches of rain.  The recurring rains have made it difficult to finish up planting and replanting corn and soybeans.  Some first cuttings of hay have also been delayed as a result of the weather.  The weather has been good for the wheat crop.  Wheat is now flowering in parts of northern Ohio and will continue to flower over the next week or so.  According to the Fusarium Head Blight forecasting system (http://www.wheatscab.psu.edu/), the risk for head scab is low in central and northern Ohio for fields flowering at this time.  Although it has rained over the last 2-4 days in parts of the flowering regions, conditions were relatively cool and dry last week, which likely reduced the risk of the head scab fungus infecting the wheat spikes. To read more about wheat diseases, see the attached article.  Armyworm adult moth catches this past week in the county were down to one moth per trap, while black cutworm moth captures were at zero.

There has been a lot going on from a farm management standpoint.  CAUV changes are being considered in both the House budget bill and in the Senate.  Ohio Farm management budgets for corn, soybean, and wheat are showing low to negative returns in 2017.  This is also the year for the U.S. Census of Agriculture, so farmers will be encouraged to participate even if they are not selected to participate.  These topics as well as others are included in the attached May edition of the Ohio Ag Manager.  I have also attached a copy of an article written by Hardin County Master Gardener Volunteer Barb Snyder regarding patching lawns.  Although this is best done in early spring or mid-August to mid-September, the information provided is useful if you have areas of your lawn that need attention.

Upcoming local activities include Dairy Feeder Weigh-in and tagging tomorrow (5/27) morning from 8:00-10:30 am at the fairgrounds.  Ag Council will be meeting on Friday, June 2 starting at 7:00 am at Henry???s Restaurant.  If you have yet to register your children or grandchildren for the June 3 Children???s Day at the Friendship Gardens, I have attached a flyer with more information about that event.  Other than that, I hope you have a restful Memorial Day weekend.  If you are not busy working in the fields, I have included some agronomy articles below for you to read if interested.

CORN REPLANT DECISIONS – SOME TIPS TO CONSIDER – Peter Thomison
Farmers confronted with poor stands due to excessive soil moisture, freezing temperatures and frosts, fungal seed decay and seedling rots, soil crusting, as well as other problems that affect corn stands, may be considering replanting their fields. Most corn that’s been planted has yet to emerge or develop much beyond the VE or V2 stage. According to the NASS (https://www.nass.usda.gov/Statistics_by_State/Ohio/Publications/Crop_Progress_&_Condition/index.php ) as of Sunday May 14, 49 percent of Ohio’s corn crop was planted – only 3 percent more than the previous week and 7 percent below the five year average. Only 24% of the crop has emerged.
Replant decisions in corn should be based on strong evidence that the returns to replanting will not only cover replant costs but also net enough to make it worth the effort. Don’t make a final assessment on the extent of damage and stand loss too quickly.  Go to https://agcrops.osu.edu/newsletter/corn-newsletter/2017-13/corn-replant-decisions-–-some-tips-consider to read more.

REPLANTING FAILED CORN STANDS – HERBICIDE CONSIDERATIONS – Mark Loux
Replanting a corn field due to weather-related stand problems usually involves killing the first planting, which otherwise really just turns into a weed.  A recent article by Dr. Aaron Hager in the U. of Illinois newsletter, “The Bulletin – pest management and crop development information for Illinois”, summarizes this and other herbicide issues for corn replant situations  (http://bulletin.ipm.illinois.edu/?p=3874).  Bottom line – the only methods to ensure complete control of the first stand of glyphosate-resistant corn are tillage or application of Select Max.  Use of Select Max must be followed by a wait of six days before replanting corn, to avoid risk of herbicide injury.  Gramoxone and glufosinate (assuming it’s not LibertyLink corn) can have substantial activity on the first stand of corn, but usually do not completely control it.  These herbicides are most effective when applied with atrazine or metribuzin, and also when corn is tall enough that the growing point is out of the ground.

 
 OHIO APPLICATOR FORECAST AND WEATHER UPDATE – Jim Noel
The wetter than normal pattern will likely continue into the first half of June now. Weather models have been trending wetter and that is important to note. The risk is increasing toward the wetter side the next 30-days. This applies to much of the corn belt as well not just Ohio. The outlook for the rest of May is for cooler and wetter than normal. It appears we have a rain event this week later Wednesday into part of Thursday then again for the weekend. Each event will average a half inch to inch but there will be variability from 0.25 inches to 1.5 inches. Even next week there could be another system about the middle of next week. It does not appear we will have a five day dry period for hay crops anytime in the next two weeks.

 DID YOU MISS THAT HAY-MAKING WINDOW? – Mark Sulc
Hats off to those who got their first cutting made during the nice weather earlier, but some of us missed it! Now we have more rain in the forecast about every three days and very wet soils from the heavy rains this past weekend across much of Ohio. While we are eager to get that first cutting made, haste will make waste if we drive on hay stands before the soils are firm enough to support the equipment. When we run hay equipment on soft soils, the wheel compaction damage to plant crowns will be like a plague for the remaining life of the stand. It will lead to lower forage yield, weed invasion, and frustrating attempts to “fill-in” the damaged stand,  and ultimately a premature termination of the stand.

Good afternoon,

The dust is flying as farmers are back in the field planting corn and soybeans.  There was little progress made on corn planting the last two weeks due to persistent rains and saturated field conditions.  As prospects for a timely start to spring planting diminish, growers need to reassess their planting strategies and consider adjustments.  Since delayed planting reduces the yield potential of corn, the foremost attention should be given to management practices that will expedite crop establishment. The attached article includes some suggestions and guidelines to consider in dealing with a late planting season.  With the emerging corn, army worm and black cutworms are pests that local farmers need to keep a watchful eye over.  Although not at economic levels, this past week army worm moth counts averaged 9 per trap, while the black cutworm moth counts averaged 26 per trap.  There are two sets of traps out so far, one near Ridgeway and another near Alger.  See the attached fact sheet from Penn State University about armyworm damage to field corn.

Corkscrewed” mesocotyl development causing emergence problems in corn – Peter Thomison

Last week I received several reports of abnormal corn emergence. Often the problems were associated with corn seedlings leafing out underground and it’s likely weather and seedbed conditions were responsible for the occurrence of the abnormal growth. Seedlings exhibiting abnormal emergence may have a twisted appearance because internal leaves start expanding before the seeding has elongated. “Corkscrewed” mesocotyl/coleoptile development may occur when the coleoptile encounters resistance (like soil crusting or a dense soil surface) as the mesocotyl elongates. Several factors (or combination of factors) may be responsible for this abnormal growth are explained at https://agcrops.osu.edu/newsletter/corn-newsletter/2017-13/%E2%80%9Ccorkscrewed%E2%80%9D-mesocotyl-development-causing-emergence-problems.

Above Normal Temps will be the Trend – Jim Noel

The wetter than normal pattern has lasted longer than expected this spring. Temperatures have behaved as expected though. The outlook for the remainder of May calls for above normal temperatures and near normal to above normal rainfall. The week of May 16 will be much warmer than normal with highs reaching into the 80s in many areas with rainfall more limited this week but by late week into this weekend rainfall be increasing again so the big window for planting this week will be through Thursday.

Soybean seedling issues – a perfect storm – Anne Dorrance, Mark Loux

Several calls last week with pictures of injured and/or diseased soybean seedlings.  For most of these situations we have the following scenario:  PPO herbicides (flumioxazin, sulfentrazone, saflufenacil) included as a component of the preplant burn down, fields planted 7 days later with fungicide treated seed, followed by 1 to 2 weeks of suboptimum growing conditions (between 40 to 50oF) for 2 weeks, and greater than 2” rain.  These conditions are very conducive to both Pythium damping-off and PPO injury.  Some of the reports from the field were with seedlings that have already croaked.  Wispy skeletons of soybean seedlings could be found on or below the surface.  Go to https://agcrops.osu.edu/newsletter/corn-newsletter/2017-13/soybean-seedling-issues-%E2%80%93-perfect-storm to finish reading this article.

Wheat Heading, Flowering, and Head Scab Risk  – Pierce Paul

After being slowed down by cold temperatures over the last 7-10 days, the wheat crop is now heading-out or flowering in some parts of the state – do not be deceived by the fact that plants still look short in some fields. Heading and flowering will continue over the next few weeks. These are very important growth stages from the standpoint of disease management, since it is critical to maintain the health of the heads and the leaves during grain fill to enhance yield. Go to https://agcrops.osu.edu/newsletter/corn-newsletter/2017-12/wheat-heading-flowering-and-head-scab-risk to read about important management decisions that must be made at these wheat growth stages.

Crop Walk Series – Amanda Douridas

Join specialists in the field this summer to see hands on what insect and disease pressure is present. The specialists will help participants identify insects and diseases and then discuss management strategies. The series begins with a Pasture Walk on May 23 at 5:30 pm. The field borders the Ohio Caverns so an optional group tour of the Caverns has been set up at 4pm ($15). The rest of the crop walk schedule is listed at the link below. The locations will be determined about a week or two ahead of time in order to find one that will display some of the issues that will be discussed. These will be in fields in Champaign County.

Good evening,

Just as it seemed the rainfall was going to end, we got more last night.  Our Extension township rainfall reporters have recorded the rainfall for April 15-30, with an average of 3.16 inches of rain in Hardin County.  Last year, the average rainfall for the same time period was 1.46 inches. Rainfall for the April 15-30 time period is 1.12 inches more than the ten year average rainfall during the same dates.  This is the 25th year of this rainfall research being conducted in our county.  If you are interested in reading the monthly summary and its effect on crops, see the attached news article.   It appears that this weekend will be a nice weekend weather-wise, so this will be a great chance for you to go to the OSU Extension Master Gardener Volunteers annual plant sale in the Arts & Crafts building at the fairgrounds.  This year’s plant sale starts at 10:00 and ends at 12:00 noon this Saturday, May 13.  See the attached flyer for more details if you are interested in purchasing some plants from local gardeners to beautify your home and landscape.

If you are like me, you are trying to keep your lawn mowed in between the rains.  There are some guidelines that should be followed when mowing your lawn to keep it healthy as pointed out by Master Gardener Volunteer Barb Snyder in attached article about Turf Tips – Mowing.  This past Friday I checked the first set of armyworm and black cutworm traps and found 3 armyworm moths and 3 black cutworm moths so they have begun their flight in the area and will soon be laying eggs in grassy areas.  Since the black cutworm is the earliest of these two pests, this week I have attached a fact sheet from Penn State University that you can read to learn more about the damage this pest causes to wheat and corn, as well as how to scout for it in the event that it becomes a problem in local fields.

Turf Tips – Mowing News Release

Black Cutworm Fact Sheet

Do you raise strawberries and are looking for a way to extend the growing season?  A practice that can accomplish this involves using plasticulture.  There will be a Strawberry Field Night at the OSU South Centers in Piketon if you are willing to travel to southern Ohio to learn about it on May 25.  I have attached a copy of the flyer for this event in case there any growers in the area who would be interested in attending.  Another event happening soon is the Soil and Water Conservation District meeting Thursday, May 18 starting at 7:30 am.  Until then, hopefully we will get some warm, dry, and windy days so that the fields can become fit again for planting.   I have included some agronomy articles below for your reading that include some timely information about this subject and others.

Frost Damage in Wheat  – Laura Lindsey, Douglas Alt, Pierce Paul

Air temperatures dropped to an average of about 25-32 degrees on at least two nights over the last few days. Understandably, some wheat producers are concerned that these temperatures may have caused some damage to their crop. We will have to see what happens over the next few days. Based on information coming out of a Kansas State University publication http://www.bookstore.ksre.ksu.edu/pubs/c646.pdf, at our current growth stage, between Feekes 9 and 10, in northern counties and between heading and flowering in southern Ohio, the yield effect of frost can range from moderate to very severe if temperatures drop to 24 – 28° F for two or more hours. Go to https://agcrops.osu.edu/newsletter/corn-newsletter/2017-12/frost-damage-wheat to read more.

Corn Management Practices for Later Planting Dates – Changes to Consider – Peter Thomison, Steve Culman

There was little progress made on corn planting last week due to persistent rains and saturated field conditions (https://www.nass.usda.gov/Statistics_by_State/Ohio/Publications/Crop_Progress_&_Condition/index.php).  As of Sunday May 7, 46 percent of Ohio’s corn crop was planted – only 4% more than the previous week. Moreover, according to NASS estimates, only 12% of the crop has emerged.  Weather forecasts indicate the possibility of more rain this week possibly continuing through the weekend. As prospects for a timely start to spring planting diminish, growers need to reassess their planting strategies and consider adjustments. Since delayed planting reduces the yield potential of corn, the foremost attention should be given to management practices that will expedite crop establishment.  To find out more, go to https://agcrops.osu.edu/newsletter/corn-newsletter/2017-12/corn-management-practices-later-planting-dates-%E2%80%93-changes-consider.

Adapting soybean burndown programs for large marestail – Mark Loux

As a result of the warm winter and early spring, weed growth in no-till fields is ahead of schedule.  Fields not treated with burndown herbicides last fall or during the earlier drier period this spring can have some large weeds at this point.  Many fields need time to dry out following the most recent rains before they will tolerate traffic, which will allow weeds to get even larger and more challenging to kill.  Large marestail can be especially problematic due to the combination of glyphosate and ALS resistance in most populations.  Cool weather can reduce the activity of the herbicides that have activity on marestail.  The standard “glyphosate + 2,4-D” burndown is not likely to control large marestail plants based on recent history, and increasing the 2,4-D rate or adding metribuzin won’t necessarily result in effective control of these plants either. Find out more about how to adjust soybean burndown programs at https://agcrops.osu.edu/newsletter/corn-newsletter/2017-12/adapting-soybean-burndown-programs-large-marestail.

Wet Weather and Evaluating Soybean Stand – Laura Lindsey, Alexander Lindsey

Saturated soils after soybean planting can cause uneven emergence and stand reductions of varying extent depending on the stage of the soybean plant and other environmental factors including temperature and duration of saturated conditions. Additionally, increased disease incidence may further reduce plant stand. While soil moisture is necessary for germination, soybean seeds will not germinate when soils are saturated because oxygen is limiting. Saturated soils during soybean germination may cause uneven emergence.

First Cutting of Forages is Fast Approaching – Mark Sulc

The warm temperatures this spring have stimulated growth of hay crops in Ohio and they are well ahead of normal development for early May. The only exception is where spring freezes significantly damaged the crop a few weeks ago. But for most stands, timing for first harvest of high quality forage is coming earlier than normal. Below are the optimal neutral detergent fiber (NDF) targets for high quality forages: Forage NDF for high producing and early lactation dairy cows is legumes: <44 (<42% is ideal), grasses: < 53% (50% is ideal), mostly legume mix: 42 to 45%, 50/50 Mix: 44 to 48%, and mostly grass mix: 46 to 49. Pure grass stands should be harvested in the late boot stage just before the heads start to peek out. If any heads can be seen, the NDF is probably 55%, past the optimal for dairy cows.

Good afternoon,

It seems as the rain won’t stop.  I overheard a lady in the lobby mention that if it keeps on raining, we might have to build an ark.  Well it hasn’t rained that much and I don’t suspect it will either.  What I do know is that about 42% of the corn is planted statewide along with about 14% of the soybean crop.  See the attached report on Ohio Crop Weather from USDA for the month of April.  The heavy rains have caused ponding in the fields here in Hardin County and that has several farmers concerned about replanting.  Will the corn and soybeans that were planted emerge okay?  What about the seedlings that are already up?  Will they survive?  There are some guidelines about this topic that I included in this week’s news article titled ‘Ponding Effects on Corn’ written by OSU Extension State Corn Specialist Dr. Peter Thomison.  It is attached to this email if you have some questions that need answered.

Wheat Growth Stages and Associated Management: Feekes 7, 8, and 9 – Laura Lindsey, Pierce Paul, Ed Lentz

Feekes growth stage 7 is characterized by the rapid expansion of the head and the presence of two nodes. One node should be between 1.5 to 3 inches from the base of the stem and the other should be about 4 to 6 inches above the base of the stem. These nodes are usually seen as clearly swollen areas of a distinctly different (darker) shade of green than the rest of the stem. Note: the upper node may be hidden by the leaf sheath – you may have to run your fingers along the stem feel it: if only one node is present, then your wheat is still at Feekes growth stage 6. Wheat will still respond to N applied at this time if weather has prevented an earlier application; however, mechanical damage may occur from applicator equipment. To learn more about wheat growth stages 7, 8, and 9, go to https://agcrops.osu.edu/newsletter/corn-newsletter/2017-10/wheat-growth-stages-and-associated-management-feekes-7-8-and-9.

Alfalfa Weevil: An early-season pest – Andy Michel, Kelley Tilmon

While most farmers are focused on getting corn and soybean in during the next few weeks, this is also the time to be aware of what alfalfa weevil larvae are doing in your forage. While February and March were warm, warmer weather on the horizon will give larvae a boost in their development. Scouting is essential to maintain a healthy alfalfa stand. Keep in mind that, while your alfalfa may be resistant to potato leaf hopper, it is NOT resistant to alfalfa weevil. Go to https://agcrops.osu.edu/newsletter/corn-newsletter/2017-09/alfalfa-weevil-early-season-pest to read more about scouting for the alfalfa weevil.

Soybean Planting Date, Row Width, and Seeding Rate Recommendations – Laura Lindsey

Over the past few years, with funding from Ohio Soybean Council, we’ve re-examined Ohio’s soybean planting date, row width, and seeding rate recommendations. Here are some things to keep in mind, as we approach planting. Soybean planting date has a large effect on yield. Yield reduction as a result of late planting ranges from 0.25 to 1 bushel/acre/day depending on row width, date of planting, and variety. In southern Ohio, soybeans should be planted any time after April 15 when soil conditions are suitable. In northern Ohio, soybean planting can begin the last week of April if soil conditions are suitable. Soybeans should not be planted until soil temperature reaches 50 degrees Fahrenheit and moisture is present at planting depth. Planting too early (when conditions are not adequate) comes with risk such as damping-off, bean leaf beetle, and late spring frosts.  Go to https://agcrops.osu.edu/newsletter/corn-newsletter/2017-09/soybean-planting-date-row-width-and-seeding-rate-recommendations to read about row width and seeding rate.

Corn Emergence and Heat Unit Accumulation – Peter Thomison

Warm, dry weather promoted significant corn planting last week, especially in western Ohio. According to USDA/NASS estimates of April 30, 42 percent of the corn crop in Ohio has been planted. However, much cooler temperatures forecast this week may slow germination and emergence of these late April plantings. Corn typically requires 100 to 120 growing degree days (GDDs) to emerge (but emergence requirements can vary from 90 to150 GDDs). To determine daily GDD accumulation, calculate the average daily air temperature (high + low)/2 and subtract the base temperature which is 50 degrees F for corn.  To find out more about heat unit accumulation with corn, go to https://agcrops.osu.edu/newsletter/corn-newsletter/2017-11/corn-emergence-and-heat-unit-accumulation.

EPA Denies Petition to Ban Pesticide Chlorpyrifos – Kelley Tilmon, Andy Michel

Recently the U.S. Environmental Protection Agency denied a petition to ban the agricultural pesticide chlorpyrifos. Chlorpyrifos has been under review for a number of months. Chlorpyrifos, an organophosphate, is the active ingredient in Lorsban and other products, and is labeled for use against a number of insect and mite pests in various field crops. The recent decision means that it will continue to be available for these uses. As with all pesticides, OSU Extension encourages applicators to exercise proper handling and application procedures to protect workers and non-workers alike from exposure. More information about pesticide safety can be found at http://pested.osu.edu/
