What’s Happening in the Fields

Posted by romeethredge on May 20, 2016

Sunny weather and dry – speeds corn growth and makes peanut thrips bad. Corn Tasseling in several fields now. Very little disease seen. We saw a spot or 2 of NCLB but no Southern rust. We did see some of the common rust but it’s no problem. A few stink bugs seen in some spots but not many anywhere.

Thrips are terrible in peanuts and several fields had to be sprayed, even some that had Thimet under them. The weird thing about thrips damage is when you see the leaf damage….. it’s too late. In other words, unless the plants are carefully scouted for thrips you can’t really tell they are working excessively, but a week later we see the damage. The good thing is peanuts are tough and can stand a lot.

We are seeing a little Aspergillis crown rot in some peanuts. It’s worse when it’s hot and dry. Watering will help this problem. We have seen a few stand problems, too… rotting seed.IMG_1177

I’d never seen a turtle like this before, he was getting around just fine in the middle of a 100 acre peanut field, why… I don’t know. Did he get Gator bit?FullSizeRender

Tassel stage is referred to as VT. And soon after we go to R1, (Reproductive stage 1) when the silks emerge from the little ears and the pollen starts falling from the tassels. The greatest production of pollen from a field will occur over 4 days, with some pollen shedding for a week or more. Over 2 million pollen grains fall from each tassel.  Peak pollen shed is mid morning and then towards late afternoon more falls, but if it’s raining or a heavy dew the plant won’t shed pollen until it dries. Also, some research shows that when the temperature goes above 86 degrees there isn’t much shed. If it’s cloudy and slightly cool, pollen may fall most of the day. Extreme heat (100 degrees) can kill some of the pollen.

Corn near Lela this week….


This is a very critical time in corn development and we don’t want any stress on the plants. Stress during silking can reduce the number of kernels per ear, not the number of rows (that was decided a while back), but the number of kernels extending out on the cob. Getting pollen shed and silking synchronized is important for high yields. Plants that came up later likely won’t get pollinated well. Other stresses like nematode spots or leached sandy spots, or overly wet spots that may be slightly behind in silking can have problems, too.

Silks are receptive to pollen for at least 5 days after coming out, they feel a little sticky. It’s amazing to me how each silk gets a pollen grain that travels to each kernel. What a miracle God does every time. The first silks come from the base of the ear. If the silks coming from the top of the ear come out too late they won’t get pollinated. The corn ear has 700 to 1,000 potential kernels and usually only 450 to 550 are expected to make it.

We saw this common rust this week, it’s cousin, Southern Rust is real bad but common isn’t.IMG_1139

Seen only a spot or 2 of Northern corn leaf blight this year. Good news as we sometimes have to spray corn early if it comes on. My son Jesse, who is helping me found this, this week.IMG_1140

Corn – A week after planting

Posted by romeethredge on March 5, 2016


Corn planted a week ago (Feb. 27th) is doing pretty well.  A pretty hard crust developed midweek in some fields and we thought we’d have to water it but the good timely rain came Thursday night. There is still danger of future frosts causing damage to this early planted corn but spreading out risk is usually a very good idea. There was some concern as we had 2 hard frosts last Saturday and Sunday mornings. Soils never did cool that much however, thankfully.

Here’s the average daily soil temperatures at the 2 inch level for this last week at the Donalsonville Weather Station.

Sat         Sun         M           Tues       Wed       Thurs     Fri

57           58           60           62           64           60           59


This next week should be just right for corn planting with less chance of future cold damage on it and warmer soil temperatures for quick emergence. When it dries off enough to plant.

Wheat – Powdery Mildew

Posted by romeethredge on February 26, 2016

Brock Ward, Miller county agent, recently posted info about what he’s seeing in the wheat fields.

He said, “Today while checking some wheat fields, I noticed some powdery mildew in the lower canopy.  This disease isn’t particularly a problem for us but under the right conditions, can warrant treatment.”

Plant Corn?

Posted by romeethredge on February 26, 2016

Whether to plant corn now or wait a while is what we are thinking about….


Lots to consider.

In some spots that question is answered due to soils being too wet. We don’t want to make a mess by planting when too wet, for sure.

Often we look at soil temperatures. On corn we look at the 2 inch depth.


As I’m writing this at 8:30 on Friday morning the 2 inch soil temperature at the Donalsonville Airport is 51 degrees. But it should rise during the day. What we really need to look at is the average over the last few days. It’s in pretty good shape. Going back in time from yesterday 58,63,64,63. At soil temps above 60 corn comes up quickly. As long as we have 55 it will still emerge but a little slower.


Tonight will be cool but after that we will be in a warming trend with no heavy rains coming so we should be good to go. I couldn’t argue with getting a field planted before then. We don’t know how cold it will get in the next few weeks, so we may want to space out plantings, but it could get real rainy in a hurry so we need to have some in the ground, too.


Here’s a photo from last year. I like the shirt. We need Doctors, carpenters, plumbers, consultants a lot but we need farmers at least 3 times a day!! I kinda like to eat that often and I like my cotton shirts, too.

Question of the Week – Horseshoe Crab

Posted by romeethredge on February 6, 2016

Last week I had a photo of something I found on the beach, a large Horseshoe Crab.  This one’s probably a female since they are usually a third larger than the males. They are amazing creatures that God created for us and our scientists and doctors are using them in amazing ways to help mankind.

The scientific name is Limulus polyphemus, and it’s found in North America along the Atlantic and Gulf coasts from Maine to Mexico. They are harmless although their tail makes us think of something that stings. They use the tail to turn themselves upright if they get flipped over. They have 10 walking legs and 9 eyes.

 I like them too, because I believe God created things pretty much as they are today and this creature confounds evolutionists. They can’t understand why it hasn’t evolved.

They are extremely important to  biomedicine because their unique, copper-based blue blood contains a substance called Limulus amebocyte lysate. It coagulates in the presence of  bacterial toxins so it’s used to test for sterility of medical equipment and intravenous drugs. The compound eyes of the horseshoe crab has helped us understand human vision.


Now for this week’s question. What is this I found in a dark drawer?
