Question of the Week – Ensign Wasp, Roach killer

Posted by romeethredge on October 1, 2015

Last week I had a small wasp for you to identify.

It is called an Ensign Wasp, because it waves it’s abdomen like a flag.

 The female Ensign wasps find a cockroach egg capsule and lay a single egg inside it. The wasp egg hatches and eats all the roaches inside the egg case, then emerges from the egg capsule (it chews a hole in the capsule to get out), mates and begins to look for another cockroach egg capsule. It prefers American cockroach egg capsules but will also parasitize smokybrown and similar roach egge capsules.

UGA Entomologist Dan Suiter says, “They do not sting humans. They’re very benefical. Don’t kill them.”

This week I want you to identify an old dam, that Daddy and I recently visited.  Where were we?

Georgia-14N Peanuts

Posted by romeethredge on October 1, 2015

This is a recently released peanut that is resistant to Peanut rootknot nematode. We visited the field that is about ready to be picked. It looked ok to me. It’s hard to tell what the yield will turn out to be but I did not see any signs of nematode feeding or damage, and this field is notorious for nematodes. The grower used NOTHING in terms of chemicals for nematode control this year, here in this field.

Of course the grower will anxiously wait to see how they yield and grade. Here’s Decatur County Ag Agent Kyle Brown checking them out.


Here’s a description by the plant breeder, UGA’s Dr. Bill Branch. “GEORGIA-14N” is a new high-yielding, high-oleic, TSWV-resistant, RKN-resistant, smallseeded, runner-type peanut variety that was released by the Georgia Agricultural Experiment Station in 2014. It was developed at the University of Georgia, Coastal Plain Experiment Station, Tifton, GA. During three-years averaged over multiple location tests in Georgia, Georgia-14N had significantly less TSWV and total disease incidence, higher yield, grade, and dollar value return per acre compared to Tifguard. Georgia-14N was also found to have a smaller runner seed size as compared to the larger runner-type check cultivar, Tifguard. Georgia-14N combines high-yield, TSWV-resistance and RKN-resistance with smaller seed size and the high-oleic trait for longer shelf-life and improved oil quality of peanut and peanut products.”

Downy Mildew

Posted by romeethredge on September 29, 2015

We are seeing some Downy mildew in several crops. I’ve seen it in vegetables and now in soybeans. It’s not usually a real problem in soybeans but it can be bad in vegetables.


Here’s how the underside of the leaves look, with some fungal growth.

Pecan Harvest Begins

Posted by romeethredge on September 29, 2015

With pecan harvest already started on Pawnee, pecan growers will soon be in the heat of the battle to get the crop harvested and sold. Dr Lenny Wells, UGA Extension Horticulturist, gives this report.  DSC_9425

” I wanted to offer this overview of how the crop looks to this point and our current market situation. This does appear to be the best crop we’ve had in 2 to 3 years, with an anticipated 110-120 million lbs. The wet spring weather gave way to a dry June, which really helped save most growers from scab. There are still some pockets of scab in the state, mostly in the Albany area and over into Southeast Georgia on highly scab susceptible varieties, but growers did a pretty good job of keeping the nuts clean this year. Insect problems were light until August and September but aphids and mites came on with a vengeance at that time. Most growers sprayed multiple times for both pests late in the season.

The crop appears to be at least 10 days to 2 weeks early. We are seeing shuck split beginning on most of the mid-season varieties at this time. We are probably about 2-3 weeks away from harvest really getting under way on our main varieties, at least in the western portion of the state. Growers east of I-75 have historically started a little later. Nut size is much better than we saw last year and most of the nuts I have cut into or cracked open have been well filled. I’ve been hearing of a lot of pops in the Pawnees that have been harvested. While this is not an unusual characteristic for this variety, I am hopeful that we do not find a high percentage of pops in all varieties, which would indicate a pollination issue.

Contract prices have been mostly in the range of $2.60-$2.70 for Desirable, Cape Fear and Sumner (I am told China has developed a taste for Cape Fear and Sumner) and $2.15-$2.25 for Stuart. Domestic consumption appears to be up and the over-supply of small pieces from Mexico that hurt the domestic market a few years ago has been exhausted so we should see an improvement in prices on the domestic market.  Cold storage levels are lower than they have been since 2012.”

Peanut PLC Payments

Posted by romeethredge on September 28, 2015


Dr. Nathan Smith, UGA Ag Economist explains what we should look for in PLC payments coming up.

Peanut Economic Update

Posted by romeethredge on September 28, 2015

Thanks to Dr. Nathan Smith, UGA Ag Economist for these informative slides concerning Peanuts.

Growers have been offered $400 contracts for 2015 and there has been some interest from growers at this price.   Shelled prices are in the high 40 cents range.  The large carryover stocks will keep a lid on prices.  Low corn and cotton price will influence some growers to move to more peanuts. Georgia and US acreage likely to increase due to generic base and PLC reference price of $535 per ton.

Lesion Nematodes on Peanuts

Posted by romeethredge on September 25, 2015

We sometimes in the past have seen lesion nematode, Pratylenchus spp.,effects on peanut pods. It was a cosmetic deal , they just looked spotted with very small spots on the pods. Our main attention and concern was and still should be on the peanut root knot nematode, Meloidogyne  arenaria.

This year I’ve seen peanuts from at least 3 fields however that seem to be adversely affected by lesion nematode. Dr. Bob Kemerait, UGA Extension plant pathologist, visited and said it does seem that the lesion nematode feeding or the subsequent entry of decay organisms in the feeding area caused some of the pods to come off prematurely.


In the fields we saw peanuts that were coming off before they could be harvested due to the affected stems.

Stressed Peanuts

Posted by romeethredge on September 25, 2015

When maturity testing peanuts, usually the scraped, interior hull color changes first in the saddle area, on top of the pod and then darkens with time, evenly around the pod. It usually does this evenly cream color to orangish to brown to black.   I and others have noticed over the years that we can get a very uneven change or mottling in some cases.  This is usually where the peanuts were perhaps growing well and had a sudden stress. Often I have asked farmers about it and if we see it they will often say something like, “Yes we had a problem with the irrigation system and couldn’t provide water to them when they really needed it”.

This year I’m seeing it in many more fields and growers aren’t reporting problems in many of the fields. This may be a clue to why we are seeing somewhat reduced yields in many fields so far this year.  Growers are reporting that yields are good but not as good as we have often seen in recent years.

We did have very high temperatures that may have stressed peanuts more than we realized.

Question of the Week – Silage Pit

Posted by romeethredge on September 25, 2015

Last week I had a photo of two ole timey silage pits. They were loaded by hand and packed by feet and then silage was removed later for feeding livestock by pulling it up with buckets and a pulley (aka tickle).


Here’s the view down into the pit. I’d hate to be thrown down there .  It reminds me of the story of Daniel in the lion’s den.


This week I have a question for you. What is this insect and what is it good for? It’s almost a half inch in length.
