Corn Harvest Begins

Posted by romeethredge on July 31, 2014

Corn harvest is going strong this week as many growers are in the fields. The moisture is 20 to 24 % so they are having to dry it.  I think it’s a good idea to get it out as quickly as possible for best yield and quality. Also, we had bad southern rust this year so our stalk strength may not be the best. If winds or storms come in we may see more falling than in some years.

Channel 4 came over yesterday to do a story about the corn harvest and here’s a link to their video.

Question of the week – Red Spotted Purple

Posted by romeethredge on July 31, 2014

Last week’s butterfly was a Red Spotted Purple, Limenitis arthemis astyanax . The larvae like to feed on wild cherry trees. The butterflies love mud puddles.

 

This week I have a forage question for you. What is this forage crop that we were cutting for hay this week? And what likes to eat it?

Target Spot in Cotton

Posted by romeethredge on July 30, 2014

We are seeing a little Target leaf spot in cotton. It doesn’t seem nearly as bad as it has been. Probably due to lots of sun and dry weather. If we get into a rainy, cloudy period it may worsen.  It often looks like a target with the concentric rings and is about marble sized. Here’s a photo of a Target Spot lesion I found this week.

Dr. Bob Kemerait, UGA Extension Scientist, has some good information about this disease as well as a risk index to help with spray decisions.

Spider Mites in Peanuts

Posted by romeethredge on July 29, 2014

Spider mites are building in peanuts. High heat and dry weather makes them worse. They are mostly seen in dryland fields. I’ve seen a few seriously affected fields lately and I’ve seen them at low numbers in several fields.

We sometimes inadvertently make them worse with other insecticide applications because we kill off some of the beneficial insects that were holding them in check. The insecticides that we use on foliage feeding caterpillars at times make spider mites worse.  We call that flaring them.

 

Here are some good comments by Dr. Mark Abney, UGA Entomologist. ” The two spotted spider mite is a challenging pest to control. It thrives in hot, dry conditions where it completes development in as little as 7 days at 81ºF. Female mites can lay up to 100 eggs over several weeks, so it is easy to see how infestations can go from light to heavy in a very short period of time.

In the early stages of infestations mites will be found mostly on the undersides of leaves. Their position on the plant and the webbing they create make getting good contact with a miticide difficult. Once infestations progress, mites will be seen on lower and upper portions of the leaves. It is very common to see “hotspots” like the one pictured below in peanut fields when infestations are just getting started. Mites will radiate out from these areas to infest the rest of the field. Populations often get established along field borders and especially borders adjacent to dirt roads or field paths.

Georgia growers are strongly urged to scout fields for spider mites as early detection can improve the odds of effective control. The ovicidal activity of miticides labeled for use in peanut is limited, so more than one application may be needed to clean up infestations. Propargite (e.g. Comite) is currently the only real option for mite control in peanut. I do not recommend the use of a pyrethroid for two spotted spider mite in peanut.”

 

I took these photos this week in Seminole County.

Pasture Caterpillars

Posted by romeethredge on July 29, 2014

Foliage eating caterpillars have been serious in pastures and hayfields for a while now and maybe worse the last week or so.  I looked at 2 Tift 85 Bermudagrass fields today that are infested with fall armyworms. They feed very quickly, often with in a few days they can leave stems, no leaves.

Often white cattle egrets are seen in  problem fields, eating on the worms. Unfortunately they don’t eat enough to control them.

Redneck Peanut Worms getting worse

Posted by romeethredge on July 29, 2014

I’m seeing lots of these rednecked peanut worms. If your field looks stunted in growth it can be partly due to this caterpillar. You have to dig into the young leaf growth to see them.

Here’s a photo that  Brock Ward, Miller County Agent took when we were looking at some peanuts last week.20140724_113702

Moths lay their eggs one at a time, and larvae feed just in the growing tip or bud of the plant. As the small leaves unfold, the damage is seen, and the infested area takes on a ragged appearance. If damage occurs early in the season, plant stunting may result.

Worms are cream-colored with a dark brown head and a reddish colored band just behind the head. Full grown larvae are approximately 1/2 inch in length. Worms are active when disturbed.

Question of the Week – Black Racer

Posted by romeethredge on July 24, 2014

Last week’s snake was a newly hatched Black Racer.

Here’s what the adult looks like.

species photo

Here’s some info from the Savannah River Ecology Lab.  http://srelherp.uga.edu/snakes/colcon.htm

“Black racers are only active during the daytime and are most active in warm weather. At night and during cool weather they take refuge in burrows or under cover such as boards or tin. Racers hunt by sight and are often observed actively foraging during the day. They are not active at night. They eat a wide variety of prey including insects, lizards, snakes, birds, rodents, and amphibians.

Racers are faster than most other snakes, very agile, and generally flee when approached, often climbing into small trees or shrubs. If cornered, however, they do not hesitate to bite. Although primarily terrestrial, they climb well and are occasionally observed sleeping in vegetation at night. Racers mate in the spring, and females lay up to 36 eggs in early summer.”

Decatur county agent, Justin Ballew, showed me this butterfly this week. What is it?

Peanuts Good to Caterpillars, too

Posted by romeethredge on July 24, 2014

Peanuts are good to us and they also are good to many things in nature. Caterpillars love to eat their leaves and blooms. There is a wide variety of caterpillars to be found in the fields now. Mostly Tobacco Budworms, Fall armyworms, Beet Armyworms, and Soybean Loopers. A few Granulate Cutworms and Rednecked Peanut worms also.   I was surprised to see a few Velvetbean Caterpillars(VBC), it’s early in the season to see them. Many fields have had to be treated or will be treated this week for foliage feeding  caterpillars.

It’s funny though, there will be a badly infested field and right down the road a field that doesn’t have a problem? So scouting is very important.

 

Here’s a VBC coming in early this year. They are big eaters, unfortunately. They wiggle around like crazy when touched.

Here is a Tobacco Budworm feeding on a peanut bloom this week. Fortunately the peanut plant produces an excess of blooms or we would be in big trouble with this, it is still bothersome and not a good thing.

_DSC7686

 You may notice that I didn’t mention Corn earworm in worms found in peanuts. There are probably some, but they look just like the closely related Tobacco Budworms. Most moths seen lately are budworm moths. Decatur county Agent Justin Ballew and I sampled several of these Heliothis caterpillars and did some dentistry to positively ID them and all we checked were Budworms (Heliothis virescens). They are often very tough to kill with pyrethroids so other chemistry is necessary, whereas their look-a-like the Corn Earworm (Heliothis zea) can be controlled more easily. Below see the ID chart provided by Dr. Phillip Roberts, UGA Extension entomologist.

larval id

Rednecked peanut worm is a small caterpillar most often found in the growing point of the plant wrapped up in leaves. We found some this week. Sometimes a field will seem to be very slow growing and this will be the problem. I think there’s a new song about them on country radio.

“Red, Red, Red, Red, Red, Red, Red Redneck.

The worms ’round here. They cause growers some fear. Talk about bad, these worms are bad. Chew peanuts, chew peanuts, chew peanuts. Spit.

Redneck worms are bittin, chewin,

and causin farmers concern

theres a lot of things i know but

I still need to learn

How this redneck can kill those redneck worms
