Grow More Hay

Posted by romeethredge on March 23, 2015

I’ve had a couple of growers lately say that hay is a profitable part of their farm and they would like to grow more of it per acre. Here’s a great meeting to go to to get some good hay and forage growing information.  Go to Georgia Forages.com and click on upcoming events. It’s on April fool’s day but it’s no joke.

Wheat – Flag leaf Stage

Posted by romeethredge on March 20, 2015

Some of our wheat is in the flag leaf stage, now. I took these photos yesterday in a field of  wheat that was planted about November 20th and is the Pioneer 26R94 variety.

Notice the head emerging in one photo. This was pretty rare though, in this field.

This is entering a critical stage for wheat as we want to protect the flag leaf for maximum grain yield.

I found no rust in this field and just a little powdery mildew. There has been leaf rust found in Mitchell county, however, already.  If we plan to make a preventative fungicide then we need to be preparing to make that application as soon as all the heads emerge unless disease threatens before that point.

Corn Popping up in Rows

Posted by romeethredge on March 20, 2015

With our recent heat the corn is really popping up in rows for us.

 This corn in photo below was only in the ground for a week. But check out the growing degree days (GDD) for last week (georgiaweather.net) . Over 100 compared to half that in the same time frame for the last 2 years.

Corn Planting Going Strong – Test Plots Going in

Posted by romeethredge on March 20, 2015

A lot of corn was put in the ground this week. We dodged some of the rains and a lot got done here lately.

Grady County Agent, Brian Hayes and I helped  put in 2 corn hybrid test plots in Decatur and the edge of Grady Counties. We also put one in at the Mim’s Farm in deep southern Seminole County.

We also have a Corn Southern Rust Sentinel Plot at the Mim’s farm about as far south as you can get and still be in Georgia, so we can tell when Southern rust moves in from the south.

These first photos are of Clint Mims, Jason Roberts on the planting rig, and Ethan Fiveash was running the rip stripper ahead of the planter rig. They are using the twin row “peanut” planter to plant corn as they usually do. These are 9 inch twins based on a 36 inch middle._DSC0595

Check out Clint’s shirt.

Next we have Jud Greene’s test plot going in near Brinson, Georgia. Marvin Stewart and Jud’s crew were helping. You can see that they have everything hooked together on the 6 row rig, 36 inch spacing.

Now near Whigham Georgia, Jerry Jones, Brian and Kevin Vantrees of Dow and he’s also an ABAC Student, put in another plot.

We work with growers and industry to put these in to get local data concerning available corn hybrids to help growers make good seed selection decisions.  These growers use their own precious time and resources to make this happen to help us all out.

Data from the last 2 years of these trials is available on this blog here, Corn Hybrid trial results 2014,2013.

Austrian Winter Peas for Cover Crop

Posted by romeethredge on March 20, 2015

Austrian winter peas make a good cover crop and they leave organic matter and some nitrogen for a future crop in the soil since they are a legume. Local grower Stan Deal is growing some this year. He plans to take it to seed harvest in this case so he can market the seed.

He wanted to get it planted in mid December but rains hampered that and he planted 2 fields on Jan 3 with a 7.5 inch spacing, no till drill into soybean stubble.

He ‘s getting some pretty good growth now and will have considerably more before the season is over.

Later we will take a Biomass Sample to send to our UGA lab to determine how much Nitrogen will be available for the future crop. We will use the Cover crop nitrogen prediction tool developed by UGA’s Julia Gaskin.

Nodulation is good on the roots, he put out a good innoculant at planting specific for Austrian winter peas to ensure the right rhizobium is present to make the process work well.

Here’s a chart from Julia showing what we can plan to get from cover crops.

Canola Aphids

Posted by romeethredge on March 20, 2015

I remember that when we grew canola back in the early nineties it seemed like we had to spray for aphids a fair amount. In the past few years we have had limited acreage but we haven’t seen a whole lot of aphids. We are seeing some aphids now in canola. Fields I’ve been in lately weren’t at treatable levels but we need to be on the lookout, and treat if needed.

Here ‘s a photo I took recently of an infested stalk.

IMG_5930

Treat seedling and rosette stage plants if populations exceed 5 aphids per leaf or15% infested plants.

Treat bud and early bloom stage if infestation exceeds 15% infested stalks (racemes).

Late flower and pod stage – Do not treat.

During bloom apply pesticides early in the morning or late in the day to avoid harming bees.

A little natural predation going on here, ladybugs love aphids.

Question of the Week – Snuggling

Posted by romeethredge on March 20, 2015

Last week I had a photo of some carrots that had recently been harvested that were twisted. Bob Youmans said that you know it’s been a very cold winter and the carrots grew that way because they were snuggling to try to keep warm.

I wrote our UGA Vegetable scientist, Dr. Tim Coolong about it and he said he can’t argue with that answer. He said, “I’ve seen this before in sweet potatoes, too. Usually I see it in a little heavier soil- typically not chemical/herbicide related just usually odd root growth due to growing conditions – it has been cold though…….”

 

 

What’s happening here? How are these seeds defying gravity, sideways on the plate?IMG_5966

Peanut Disease and Nematode Update

Posted by romeethredge on March 17, 2015

Updates for Peanut Disease and Nematode Management in the 2015 Season

Dr. Bob Kemerait, UGA Extension

Disease and nematode management will be a critical component for profitability and success in the 2015 season.

  •  It is expected that there will be a significant increase in acreage planted to peanut in 2015.  Planting more peanuts at the expense of good crop rotation will surely lead to a reduction in yield over time.

  • The 2015 Peanut Rx app is available FREE for iPhones at the App store (search “Peanut Rx”) and on Android phones at Google Play (search “UGA Peanut Rx”).  

 

  • Some growers are interested in using Proline fungicide either in-furrow or as an early-season treatment for management of white mold.

Question:  When would you consider a proline application early?

Answer: I would certainly consider an in-furrow use of Proline for fields where risk to CBR is high or where it has been a problem in the past.  An in-furrow use is an effective treatment for CBR.

I would also consider use of in-furrow Proline where additional efforts to manage white mold are desired, e.g. where white mold has been a problem, where fields are planted peanut to peanut, and perhaps in years where excessively high summer temperatures are expected.

NOTE:  An in-furrow use of Proline for control of white mold is NOT the BEST use of the product (banded early emergence applications are generally more consistent in protecting yield).  However, for growers who do not want, or are unable, to put out the banded application, an in-furrow application can have some efficacy.

From the data, the most effective way to use Proline is as a post-emergent, banded application likely between 3 and 5 weeks after emergence.  This treatment is most appropriate for fields at increased risk to white mold.  Factors that increase risk to white mold include:

A.  Short rotations with peanut.

B.  Fields with a history of losses to white mold

C.  Seasons that begin very much warmer than normal.  (Growers will have several weeks after planting to decide if such is the case.

  •  VELUM Total is now labeled for use in peanut as a management tool for nematodes and thrips.  The rate for peanut will be 18 fl oz/A.  VELUM Total can be mixed with liquid inoculants and in-furrow fungicides.

  •  Registration for ELATUS fungicide (a combination of Abound and the SDHI fungicide “solatenol”) is expected to occur in time for use this growing season, but has not occurred yet.  When it is labeled, ELATUS will be an effective fungicide for management of leaf spot and soilborne diseases.

What if Chlorothalonil is short this season for Leafspot control?

Posted by romeethredge on March 17, 2015

  • There are a number of reports suggesting that chlorothalonil (sold under many brand names to include Bravo, Echo, Equus, Chloronil, etc,) will be in short supply in 2015.  As chlorothalonil is an important fungicide for management of leaf spot diseases of peanut, a shortage could have a significant effect.  Below are some recommendations from Dr. Bob Kemerait, UGA Extension, for dealing with challenges that could occur.

    • The first two applications of chlorothalonil (30 and 40 DAP, days after planting) can be removed IF Proline, 5.7 lf oz/A is banded at approximately 35 DAP and a Provost program is initiated at 60 DAP.  The first two chlorothalonil applications can also be omitted if Priaxor is used on the crop approximately 45 DAP.

    • Chlorothalonil can be extended by tank mixing a reduced rate (e.g. 1.0 pt/A rather than 1.5 pt/A) with 2 fl oz/A Tilt/Bumper, 5 fl oz/A Topsin-M, or Alto, 5 fl oz/A.

    • Tilt-Bravo or Echo-Propimax can be substituted for chlorothalonil.

    • An application of Elast (1.5 pints/A) can be used to replace an application of chlorothalonil.

    • For a SINGLE application during a season, Topsin-M, 10 fl oz/A, can replace an application chlorothalonil.

    • Absolute (trifloxystrobin + tebucoanzole) and Stratego (trifloxystrobin + propiconazole) can be substituted for chlorothalonil.
