Peanut Acreage Up in 2015

Posted by romeethredge on July 20, 2015

Georgia Plants Highest Peanut Acreage Since 1991

The NASS USDA Acreage Report was released on June 30 giving the first planted acreage estimates based on surveys.   Planted acres of peanuts in Georgia were pegged at 800,000 acres, up 200,000 acres over last year for an increase of 33.3%.   The US peanut planted acres is estimated as 1.6 million acres.   This is an increase of 18% from 2014 and the highest since 2012 figure of 1.638 million acres.   Growers   have until July 15 to certify planted acres with FSA.   The first release of FSA reported acreage should come in mid-August. Thanks to Dr Nathan Smith, UGA Extension Ag Economist, for this report.

Bermudagrass Stem Maggot

Posted by romeethredge on July 20, 2015

We have been seeing and getting reports of bermudagrass stem maggot damage all across the southern 2/3 of Georgia. Most folks have cut their second cutting and many have started on their third cut. I took the photo below of damage last week.

Dr Dennis Hancock, UGA Extension forage scientist, gives this report, “I’ve had a fairly sizeable number of Agents reporting that they have producers who have gotten 3-8 inches of regrowth on their third cut’s regrowth, only to have it stunted by the BSM. This is often enough regrowth (>6 inches) to shade the base of the bermudagrass such that it won’t try to grow through the damage. As such, this is the worst case scenario, and the only thing for it is to clip the bermudagrass back and use an insecticide to suppress the BSM population long enough for the bermudagrass to grow up.


Following the recommendations found here (, many producers have successfully used a pyrethroid to suppress the BSM fly populations. But, timing is CRITICAL! Producers spraying 7-10 days after the previous crop was mowed have found that this one application will protect the crop at least until it is 3-4 weeks old.

Meaning: the second spray is not likely to be needed. By the time it gets 3-4 weeks old, the damage done to the top 2-3 leaves at that point would not be enough to justify the cost of the spray and the damage done by the spray rig driving across the field. If it is 3-4 weeks old and starting to show signs of damage, it would be better to harvest the crop and protect the regrowth.

Also, keep in mind that the more susceptible varieties  are common, Alicia, Coastal, Russell, and Tifton 44.”

Ten Peanut Insect Questions

Posted by romeethredge on July 17, 2015

TEN PEANUT INSECT QUESTIONS and ANSWERS for 2015 Dr. Mark Abney, UGA Extension Entomologist

Q1. Lesser Cornstalk Borer (LCB) took me to the cleaners last year. What do I spray this year, what rate and how often?

  • Do you have any LCB now? If not, do not treat. 2014 was the worst LCB year in memory, and treating fields this year just because there was a problem last year is not a good strategy. Scout your peanuts!

Q2. Everybody is talking about Diamond (novaluron) & Prevathon (chlorantraniliprole) for LCB. Which one do I spray and how much?

  • Neither of these products is currently recommended by UGA Extension for LCB because there are not enough data. Nevertheless, both look promising. If you choose to use one of these products, consult the label for rates.

  • IMG_7244

Q3. How good is Dimilin (diflubenzuron) on lesser cornstalk borer?

  • Trial results are variable. It is not listed in the UGA Pest Control Handbook for LCB.  Dimilin is an insect growth regulator and it is not as hard on beneficials as Lorsban or other broad spectrum materials, and it will control foliage feeding caterpillars.

Q4. Can I apply liquid chlorpyrifos to my peanut for burrower bug and/or LCB?

  • NO.

Q5. Should I apply granular Lorsban for burrower bugs?

  • Do you consistently have burrower bug damage? If not, then NO. If yes, then you probably should; there are no other options for controlling this pest. Be sure to scout Lorsban treated fields for caterpillars and spider mites.

Q6. I hear they are catching burrower bugs in light traps this year. What does that mean?

  • No one really knows at this point. Burrower bugs are native to the US and feed on a lot more than peanut. We cannot predict if 2015 will be a bad year.

Q7. Spider mites killed me last year; do I need to be worried about spider mites in my peanuts in 2015?

  • You should be monitoring fields for pests including spider mites. Spider mite infestations usually start at field borders, especially those adjacent to dirt roads, and dry corners. Comite and Omite (same AI) are the only legitimate option(s) available. Early detection and good miticide coverage are essential to control.

  • Q8. When do I spray for three cornered alfalfa hopper?

  • There is no validated economic threshold. A threshold that was proposed in the early 2000’s in response to increasing TCAH populations on “Georgia Green” peanut is:


This threshold is probably too low for current varieties. Work is being done now at UGA to determine thresholds for this pest.

Q9. What can I spray for TCAH?

  • Pyrethroids are pretty much it, but they will kill beneficial insects, and you will probably have more caterpillar pressure.

Q10. Should I spray these caterpillars in my peanuts?

  • PART I. Probably not, but since you are going to spray them anyway, please do not mess up. Pyrethroids are cheap, but they kill beneficials, and they do not kill all caterpillar species. There are plenty of good, selective caterpillar materials listed in the UGA Pest Management Handbook.

  • PART II. The threshold for foliage feeding caterpillars in peanut is 4-8 larvae per row ft. Use the lower end (4) on smaller or stressed peanuts and the upper end (8) on healthy, vigorously growing plants.

Question of the Week – Crepe Myrtle and Aphids

Posted by romeethredge on July 17, 2015

Yes, last week I had a photo of a Crepe Myrtle tree. Dusty Smith, Seminole County Ag teacher, answered correctly and he also knew that aphids are often the problem with them causing sticky honeydew and black sooty mold in the bottom of the canopy.

Here’s a link to a good UGA publication concerning growing Crepe Myrtles.


Here’s this week’s question.  What is this I found on some peanut leaves this week and why are some of the “caps” off? Is this a good or bad thing to find these?

Ultra Late Soybeans after Corn Harvest

Posted by romeethredge on July 16, 2015

Ultra late soybeans after corn are being planted now and getting them in early will help yields.  Here are some links to past information I’ve posted about this subject.

Ultra Late Soybeans – Water Critical

Ultra Late Soybeans after Corn

Here’s some good information from UGA Soybean and Cotton Scientist, Dr. Jared Whittaker, concerning Ultra Late soybeans. Some of these charts represent only one year of data and so we know we could get different results if averaged over several years however it’s still good information and these results follow what we’ve experienced.

It’s important to know that in some years we don’t get these yields. Weather affects this a lot.

Mid-Season Irrigation for Peanuts

Posted by romeethredge on July 16, 2015

We are in a critical water stage for our summer crops, except for corn. Rains have been spotty with some dry areas remaining. Remember we’re never more than about 3 days from an agricultural drought, especially on sandy ground.  DrWesley Porter, UGA Engineer gives us some good peanut watering advice.

“Our ample rainfall seemed to stop later in May and into June.  With the lack of rainfall we also had an excess of heat move in.  Typically peanuts do not require much water early in the season but the lack of rainfall and extreme continual heat may have pushed some producers to turn their pivots on.  I would say that this was a good decision and recommended practice.  We had depleted much of our non-irrigated soil moisture due to the hot and dry period.

We have as of the end of June began to pick up some rainfall from scattered mid-afternoon Thunderstorms.  These rains are beneficial and very welcome.  However, high intensity rainfall does not do a very good job of refilling your soil water profile.  Keep that in mind and don’t bank fully on these high intensity events to fully provide the required water you need.

Based on the split planting of peanuts due to the warm early season weather we will be moving into one of two stages during July, either ramping up to peak water use and then dropping off, or just getting ready to move into peak water use.  The graphic to the right should give you a good idea of where we will stand for the 4 weeks of July.  Keep track of your rainfall, and supplement it with irrigation.  On rainfall events from 0.25” to 1” it is good to assume a 90% efficiency and on events over 1” it’s probably safest especially if it is a high intensity event to assume around a 75% efficiency.  Make sure you don’t short yourself on soil moisture as this can be detrimental.   Remember this requirement is IRRIGATION and RAINFALL! “

Corn Harvest

Posted by romeethredge on July 15, 2015

Corn Harvest is going on this week in several fields.  Rain has slowed harvest in some areas, but its needed on other crops.  I’m surprised the moisture is so low for this time of year, 25 to 23%, I even heard a 21% grain moisture.  Grain quality looks very good. Yields are good. I’ve heard of 258 to 274 to 280 yields over large areas of 3 different fields.  We are seeing some corn falling in areas due to weather so we need to get it out as we can.

 Some soybeans have been planted already behind  corn harvest, as soon as the combine gets out of the way. That’s good as these will have more time to grow and produce beans. I’ve had some questions about if soybeans planted like this, when peanuts are in the rotation, if it hurts peanut yields in the future. We’ve not really seen that happen. Growers are aware that soybeans could cause problems in a peanut rotation and are careful to use good soilborne disease chemistry  on the peanuts and also to use nematicides if needed. Some of the best , high yielding peanut growers we have also grow some ultra late soybeans after corn.

Georgia-14N Peanut

Posted by romeethredge on July 14, 2015

I looked at these Georgia-14N peanuts yesterday and they really look good. They are 70 days old in an irrigated sandy field that has had severe peanut rootknot nematodes. Vines are good on this new nematode resistant, small seeded, high-oleic variety developed by Dr. Bill Branch, UGA Scientist.

“Georgia-14N is a high yielding, medium-seeded, high-oleic runner-type peanut (Arachis hypogaea L. subsp. hypogaea var. hypogaea) cultivar with resistance to tomato spotted wilt virus (TSWV) and root-know nematode (RKN).  Georgia-14N originated from a cross made between Georgia-02C x F4 (Georgia-01R X COAN).”

Question of the Week – Red Breast Sunfish

Posted by romeethredge on July 10, 2015

Last week I had a photo of a Red Breast Sunfish that we often call Red Belly bream, they are fun to catch and good to eat.

Here’s are comments from Dr. Gary Burtle UGA Scientist,”This is a red breast sunfish.  Note the long black opercular flap.  Some confuse with the long ear sunfish, but that one is not as likely to be red bellied.”


This week I have a photo of a yard ornamental tree and I want you to identify it and tell me what are the problems that folks have with them?
