Question of the Week – Predacious Stink Bug Eggs

Posted by romeethredge on July 23, 2015

Last week I had a photo taken under magnification of Spined Soldier Bug (beneficial stink bug) eggs. I saw an adult sucking the life out of a caterpillar in the peanut field a few days ago. Here’s the small stink bugs that had just hatched out. The white capsules with the open tops where where they came from.

 Caterpillars in peanuts have decreased in some fields this week due to this predator and others and due to parasites working on the caterpillars, too. stink bugs stink bug eggs

Here’s the same egg mass without magnification, as I found it in the peanut field.


This week, another entomology question. I found this large moth in a soybean field this week. What is it?

Cotton Angular leaf Spot

Posted by romeethredge on July 23, 2015

 COTTON ANGULAR LEAF SPOT (aka bacterial blight):   Angular leaf spot is a bacterial disease caused by the pathogen now known as Xanthomonas axonopodis pv. malvacearum.  We have not seen a major outbreak in many years but are seeing it more frequently this year.   I have seen it in a couple of fields here in Seminole county, and I’ve had reports of it from consultants in Decatur county.

Here’s advice from Dr. Bob Kemerait, UGA Extension Plant Pathology. 

A.  The disease is caused “angular leaf spot”  because the water-soaked lesions are typically defined by the veins of the cotton leaf and take on an angular appearance.

B.  As the lesion develops, it can take on an appearance more like target spot  ( like in second photo below)  but is typically differentiated from target spot because of a yellow halo around the spot and because the initial water-soaked lesion is still discernable in the larger lesion.

C.  Angular leaf spot CAN NOT be managed with a fungicide or anything else applied to the leaf.

D.  While the bacteria can be spread through moisture and splash from irrigation and rain, reducing irrigation is likely to cause more harm to the crop during hot weather than it will help manage the disease.

E.  Angular  leaf spot may produce rapid defoliation of the cotton crop in severe cases.  However, yield losses are not reported to be catastrophic and in a worst-case-scenario may approach 10% (note:  worst-case-scenario).

F. The angular leaf spot found thus far in Georgia has been south of Tift County and west of I-75; it is currently relatively confined.

Farm Program Update

Posted by romeethredge on July 22, 2015

Farm Program Update from Dr Nathan Smith, UGA Extension Ag Economist

HIP Provision Rescinded

On Monday, July 6, FSA released notice CM-770 providing notification that the policy requiring covered commodities to have similar HIP’s for farms to be combined is now rescinded.   HIP stands for Historical Irrigation Percentage and applies to the ARC-CO program in HIP counties where at least 25% of a commodity’s acreage is irrigated and 25% non-irrigated.  Commodity groups worked with FSA to take another look at the policy due to concerns that it would effectively eliminate combinations of farms and create problems with crop rotations if producers couldn’t combine farms because of different HIP’s.

No PLC Payment on 2014 Barley, Oats or Wheat

The June 30 Agricultural Prices report showed final 2014 season average price for small grains.   The final prices for barley, oats and wheat are above the Reference Price, thus not triggering a PLC payment for the 2014 crop.  Peanuts project a payment rate of $95.73 per ton before the 85% payment factor and any sequestration subtracted.   Corn could have a zero or small PLC payment while grain sorghum and soybeans will not trigger a PLC payment for 2014 crop year.   However, ARC-CO payments should trigger for most counties based on price.

2014 Marketing Year Average Price

Commodity Marketing Year Reference Price 2014 MYA Price PLC Rate*
Barley Jun. 1-May 31 $4.95 $5.30 $0.00
Oats Jun. 1-May 31 $2.40 $3.21 $0.00
Wheat Jun. 1-May 31 $5.50 $5.99 $0.00
Peanuts Aug. 1-Jul. 31 $535 $439.27 $95.73
Corn Sep. 1-Aug. 31 $3.70 $3.69 $0.01
Grain Sorghum Sep. 1-Aug. 31 $3.95 $7.27 $0.00
Soybeans Sep. 1-Aug. 31 $8.40 $10.08 $0.00

Good News – We are Eating More Peanut Butter!

Posted by romeethredge on July 21, 2015

Edible Use of Shelled Kernels Up 4.5%

The June 30 Peanut Stocks and Processing Report by NASS USDA indicates that total use of shelled edible kernels is up 4.5% over last year.  The increase is being driven by the peanut butter category, up 9% over last year.  This is a strong increase and is being credited toward innovative products being introduced in the market.  Candy use is down according to the report snack use about the same.  In-shell use is down which is not encouraging for the Virginia-type market.

Scouting for Sorghum Midge

Posted by romeethredge on July 21, 2015

Sorghum Midge is tough to scout for. They are smaller than house flies, orangish and can be elusive. Dr Angus Catchot, entomologist in Mississippi, uses some good concepts in this blog post, Scouting for Sorghum Midge with Confidence, to check for midge in grain sorghum which can really hurt yields. Soon after head comes out is the critical time and he has a method of putting a gallon ziplock bag over the grain head and thumping it and the midges will fly up to the top of the bag, you don’t even have to close the bag.

Dr. David Buntin, UGA Entomologist, says we need to scout and not do automatic sprays due to possibility of flaring white sugarcane aphids. Also use chemistry that doesnt kill beneficials if possible.

Here’s one of the site’s photos. Go to Dr. Catchot’s blog post for lots of information and more photos.

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.
