Alfalfa Weevil is in the County

For those of you who have Alfalfa in the county, be on the lookout for Alfalfa weevil. These are pictures shared with me last week.  A few weeks ago in the CORN Newsletter information was shared about scouting for this pest.

Alfalfa fields should be scouted weekly for weevils until at least the first harvest.  Follow-up scouting may be needed after the first harvest in heavily infested fields.

Spot problem fields early by checking alfalfa tips for feeding damage – small holes and a tattered appearance.  Fields that have a south-facing slope tend to warm up sooner and need to be checked for weevil earlier.

eBarns- Putting Data in Producers’ Hands

by: Garth Ruff, Beef Cattle Field Specialist
Source: https://u.osu.edu/beef/2022/08/24/ebarns-putting-data-in-producers-hands/
In 1914, the Smith-Lever Act called for the establishment of an Extension program within land grant universities. The Act spells out that Extension is to disseminate “useful and practical information on subjects related to agriculture” and to disseminate reach being conducted at the experiment stations (OARDC here in Ohio). Over the year this “translation” of research has been done in a variety of ways including field days, seminars, one-on-one instruction, and via printed or digital newsletters. Traditionally, faculty who had Extension responsibilities on campus led research efforts, wrote academic journal articles, and then it was up to someone to share and interpret data that was meaningful to clientele in the counties across the state. eBarns, much like Ohio State Extension’s eFields publication does just that, putting the data of applied research into the hands of producers who can then interpret the research to make production decisions. eBarns in new in 2022, focusing on applied livestock, forage, and manure management research across Ohio. The report can be found online at go.osu.edu/ebarns2022. Within the report readers will find forages, dairy, beef, small ruminants, manure nutrients, and swine research projects highlighted and summarized in a user-friendly format. If there are questions regarding a study within the 2022 eBarns report or interest in becoming involved with eBarns efforts in the future contact Garth Ruff at ruff.72@osu.edu.

Timely Frost Seeding Improves Pasture, Hay Stands!

Chris Penrose, Extension Educator, OSU Extension, Morgan County

If and when the seed can reach the soil in late winter while there is still freezing and thawing activity, clover can fill in bare spots and add to the density of the pasture stand.

In the past, as we’ve talked about the virtues of frost seeding, we’ve suggested it’s something that is best to occur in February or March during the period when the ground is freezing and thawing almost daily. In recent years freezing and thawing temperatures haven’t always happened after mid-February. Since it’s the freezing and thawing over time that gives frost seeding a great chance to work, the time for frost seeding may be upon us soon.

Frost seeding is a very low-cost, higher-risk way to establish new forages in existing fields by spreading seed over the field and letting the freezing and thawing action of the soil allow the seed to make “seed to soil” contact allowing it to successfully germinate. When you see soils “honeycombed” in the morning from a hard frost, or heaved up from a frost, seed that was spread on that soil has a great chance to make seed to soil contact when the soil thaws. I think the two biggest reasons why frost seeding fails is people wait too late to frost seed and the seed never makes good contact with the soil. I have heard some say that they like to “overseed” or just spread seed over an established stand. Let’s face it, if the seed does not land on the soil but on existing living or dead vegetation, it does not have a chance to successfully germinate: you need exposed soil. In light of the recent snow that’s arrived and/or expected throughout Ohio, it’s important to also note that frost seeding can be done over a thin layer of snow, however, it’s important to realize that rapid snowmelt can cause the seed to be washed away from where it’s needed.

Don’t get Burned by Hopperburn—Check Alfalfa for Potato Leafhoppers

By:  Andy Michel, Mark Sulc, Curtis Young, CCA, Kelley Tillmon

alfalfa leaf hoppers on dimePotato leafhopper (PLH) adults arrived in Ohio during the last week of June and the first week of July. Since then, the eggs have hatched and we are now seeing late-stage nymphs and adults infesting alfalfa fields.  A few fields are showing the typical “hopper burn”, which is a triangular yellowing from the center of the leaf to the leaf margin. The more mature the crop of alfalfa is since the last cutting, the more the hopper burn symptoms will be showing. Hopper burn will also become more pronounced in areas of the state that are short on rain or are predicted to become drier because the alfalfa will not be able to outgrow the feeding activity of PLH.  Scouting now and making appropriate management decisions based on the scouting can help avoid serious damage to the crop.

Alfalfa Weevil Infestations Becoming Severe in Some Fields

GDD

Figure 1: Accumulated growing degree days (base 48°F sine calculation method) for January 1- May 2, 2021, at several CFAES Ag Weather System (https://www.oardc.ohio-state.edu/weather1/) locations and additional NOAA stations around Ohio (data courtesy of the Midwestern Regional Climate Center (https://mrcc.illinois.edu).

By Mark Sulc, Aaron Wilson, Kelley Tilmon, Greg LaBarge, CPAg/CCA, Curtis Young, CCA, Andy Michel, Beth Scheckelhoff

Alfalfa fields across Ohio have been observed with alfalfa weevil infestations, some with high numbers and severe feeding damage to the alfalfa.

Accumulation of heat units (growing degree days or GDDs) for alfalfa weevil growth have progressed across Ohio and are now in the 325 to 575 heat unit range indicative of peak larval feeding activity (Figure 1). We are about 2 weeks ahead of GDD weevil accumulation last year.

From the road, severe weevil feeding can look very much like frost injury (Figure 2). Do not be fooled, get out and scout! We have observed very minor frost injury to alfalfa from last week’s cold nights, so if you see “frost injury” in alfalfa, it is more likely to be severe alfalfa weevil feeding damage.  For more information on scouting and signs of damage, see the April 20 article in this newsletter: (https://agcrops.osu.edu/newsletter/corn-newsletter/10-2021/alfalfa-weevil-%E2%80%93-it%E2%80%99s-closer-you-think).

Forage Planting – How to Do It Well

By:  Mark Sulc and Jason Hartschuh, CCA

The window of opportunity for spring forage seedings has been very tight the past three years. Are you ready to roll?

Early spring provides one of the two preferred times to seed perennial cool-season forages, the other being late summer. The outlook for this spring is for probabilities of above-average precipitation in April and May. Planting opportunities will likely be few and short. An accompanying article on preparing now for planting along with the following 10 steps to follow on the day you plant will help improve chances for successful forage establishment.

  1. Check now to make sure soil pH and fertility are in the recommended ranges.  Follow the Tri-state Soil Fertility Recommendations (https://forages.osu.edu/forage-management/soil-fertility-forages).  Forages are more productive where soil pH is above 6.0, but for alfalfa, it should be 6.5 – 6.8. Soil phosphorus should be at least 20 ppm for grasses and 30 ppm for legumes, while minimum soil potassium should be 100 ppm for sandy soils less than 5 CEC or 120 ppm on all other soils. If seedings are to include alfalfa, and soil pH is not at least 6.5, it would be best to apply lime now and delay establishing alfalfa until late summer (plant an annual grass forage in the interim).

Precautions for Feeding Frosted and Drought-Stressed Forages

Hay bales in the field

Livestock owners feeding forage need to keep in mind the potential for some forage toxicities and other problems that can develop this fall. High nitrates and prussic acid poisoning are the main potential concerns. These are primarily an issue with annual forages and several weed species, but nitrates can be an issue even in drought-stressed perennial forages. There is also an increased risk of bloat when grazing legumes after a frost.

Nitrate Toxicity

Drought-stressed forages can accumulate toxic nitrate levels. This can occur in many different forage species, including both annuals and perennials. Several areas in Ohio have been dry of late. Corn, oat, and other small grains, sudangrass, and sorghum-sudangrass, and many weed species including johnsongrass can accumulate toxic levels of nitrates. Even alfalfa can accumulate toxic nitrate levels under severe drought stress.

Before feeding or grazing drought-stressed forage, send in a forage sample to be tested for nitrates. Most labs now offer nitrate tests, so it is likely that you can get a forage nitrate test by your favorite lab. Several labs are listed at the end of this article that does nitrate testing. This list is for your convenience and no labs are intentionally omitted. Check your chosen lab’s website or call them and follow their specific instructions about how to collect and handle the sample. The cost is well worth it against the risk of losing animals.

See the following references for more details:

Nitrates in Cattle Sheep and Goats (University of Wisconsin Extension) https://fyi.extension.wisc.edu/forage/nitrate-poisoning-in-cattle-sheep-and-goats/

Nitrates and Prussic Acid in Forages (Texas Cooperative Extension) http://forages.tamu.edu/PDF/Nitrate.pdf

Nitrate accumulation in frosted forages. Freezing damage slows down metabolism in all plants, and this might result in nitrate accumulation in plants that are still growing, especially grasses like oats and other small grains, millet, and sudangrass.  This build-up usually is not hazardous to grazing animals, but green chop or hay cut right after a freeze can be more dangerous. When in doubt, test the forage for nitrates before grazing or feeding it. Continue reading →

Scout now for cressleaf groundsel in hayfields, or pay the price in May

Cressleaf GroundselBy Mark Sulc, OSU

Some hay producers have been unpleasantly surprised in the past when cressleaf groundsel infestations became evident in their hay fields in May prior to first cutting.  Cressleaf groundsel in hay or silage is toxic to animals, and infested areas of the field should not be harvested and fed.  Groundsel is a winter annual, emerging in late summer into fall when it develops into a rosette that overwinters.  Growth restarts in spring, with stem elongation and an eventual height of up to several feet tall.  The weed becomes evident in hayfields when it becomes taller than the alfalfa/grass and develops bright yellow flowers in May.  The problem with passively waiting until this point to discover that the hay is infested with groundsel is that: 1) it’s too late to control it with herbicides; and 2) hay from infested areas has to be discarded instead of sold or fed, and large plant skeletons are still toxic even if herbicides were effective on them.  Groundsel plants finish their life cycle in late spring, once they flower and go to seed, so it should not be a problem in subsequent cuttings.

Fall Forage Management Tips

Alfalfa Field

By Mark Sulc, OSU Extension

Fall is a great time to take care of some very important aspects of managing forage hayfields and pastures. Below is a list of things that when done in the fall can help avoid big headaches this winter and next spring or even next summer.

  • One of the most important things to do now is to pull soil samples and get a soil test. Ask for the 2020 Tri-State Fertility Recommendations to be applied to the results. Apply fertilizer to correct any soil deficiencies and replace nutrients that were removed in hay and silage. Fall is a great time to apply both P and K to prepare established forage stands for winter. Soil sampling and testing are especially critical in preparation for making new forage seedings next spring or summer. Now is the time to apply lime to raise low soil pH levels for next year’s seedings. Soil preparation now will also help you be ready to plant when the first break in the weather comes next spring. Many headaches with forage stands can be greatly alleviated with proper fertility levels. Deficient fertility leads to weak forage stands that are susceptible to stresses (including winter injury) and especially weed invasion. Links to additional soil fertility resources can be found at https://forages.osu.edu/forage-management/soil-fertility-forages. Continue reading →

Late Season Forage Harvest Management

Alfalfa Harvest

The best time to take the last harvest of alfalfa and other legumes is sometime in early September in Ohio, for the least risk to the long-term health of the stand. These forages need a fall period of rest to replenish carbohydrate and protein reserves in the taproots that are used for winter survival and regrowth next spring.

 

Many forage producers around the state have been cutting this past week and are continuing into this week. It will be ideal if this is indeed the last harvest of the season. But some growers might try to squeeze out another late cutting, and others have fields that are not quite ready for harvest right now. Like most farming decisions, there are trade-offs and risk factors to consider when making a fall harvest of forage legumes after the first week of September. This article reviews the best management practices and risk factors affecting fall cutting management. Continue reading →

Short-Season Forages for Late Summer Planting

Figure 1. Early November growth of Italian ryegrass (left) and oat+winter rye (right) after mid-September planting in Ohio

By Mark Sulc, Bill Weiss

Short-season forages planted in late summer can be sources of highly digestible fiber in ruminant livestock rations. There are several excellent forage options that can be considered for no-till or conventional tillage plantings in the late summer or early fall planting window. These forages can be a planned component of the overall forage production plan. They can be utilized on land that would otherwise sit idle until next spring, such as following wheat or an early corn silage harvest.

Oat or Spring Triticale silage
These cereal forages can be planted for silage beginning the last week of July and into early September. Dry matter yields of 1.5 to 3 tons per acre (about 5 to 5.5 tons at 30 to 35% DM) of chopped silage are possible if planted in late July to early August. Harvesting between late boot, or early heading, will optimize quality. Yields will be lower for plantings made in early September, in which case late autumn grazing would be a more viable option.

The potential feed value of oat silage can be similar to mid-bloom alfalfa.  As a grass, maximum inclusion rates in diets for animals with high nutritional demand (e.g. lactating cows) are less than those for alfalfa, but it is a very acceptable feed.

Spring Triticale is the biotype of the hybrid cross between cereal rye and wheat (there is also a winter biotype that acts like winter wheat). In our research, oat averaged slightly higher fall yields than spring triticale, but this varied across years. If cut at the proper maturity, spring triticale forage has a higher feed value than oat, similar to early-bloom alfalfa. Seed cost for spring triticale is usually higher than oat, but it is later maturing than oat or barley and will maintain its forage quality for an extended harvest window. Continue reading →

Late Summer Establishment of Perennial Forages

Preparing a firm seedbed for foragesBy Mark Sulc

The month of August provides the second window of opportunity for establishing perennial forage stands this year. The primary risk with late summer forage seedings is having sufficient moisture for seed germination and plant establishment, which is a significant risk this summer given the low soil moisture status across many areas.

The decision to plant or not will have to be made for each individual field, considering soil moisture and the rain forecast. Rainfall/soil moisture in the few weeks immediately after seeding is the primary factor affecting successful establishment.

No-till seeding in August is an excellent choice to conserve soil moisture for good germination. Make sure that the field surface is relatively level and smooth if you plan to no-till seed because you will have to live with any field roughness for several years of harvesting operations.

Sclerotinia crown and stem rot is a concern with no-till seedings of alfalfa in late summer and especially where clover has been present in the past. This pathogen causes white mold on alfalfa seedlings and infects plants during cooler rainy spells in late October and November. Early August plantings dramatically improve the alfalfa’s ability to resist the infection. Late August seedlings are very susceptible to this disease, with mid-August plantings being intermediate.
