Wheat Fusarium Head Blight or Scab

Posted by romeethredge on April 17, 2015

Last year,2014, was the worst Fusarium Scab we have ever seen here on wheat.  We had rainy warm conditions during flowering (just as heads emerged) and everything hit just wrong.  This time we were dry when most of the wheat here was heading, so we are hoping not to see much this year. But now that conditions have worsened in terms of being favorable for the disease, we need to be thinking about it. Some growers may decide to apply fungicides but they must be applied at the right time, preemptively, and may just give us some suppression.

There is a Fusarium Head Blight Prediction Center that is showing as you see below a high risk now for our area. Go to the site and click on Georgia to get more info.  Fullscreen capture 4152015 112901 AMHere is a list of some of our wheat varieties and their resistance to this problem.

Dr. Alfredo Martinez, UGA Plant Pathologist, gives these wise words concerning the use of chemical control. “Control using fungicides can be difficult due to the specific time the fungicides need to be deployed and because selection of fungicides labeled for FHB is limited. Timing of fungicide applications is crucial for the control of FHB. Foliar sprays must be applied at the first sign of anthers extruding from the wheat (anthesis). Triazoles work best when applied right before or at early flowering on the main stem heads. The use of nozzles that provide good coverage of the spike is essential for proper disease management. The fungicides labeled for FHB disease-suppression only are listed in Table 3″

Here is what the heads look like if affected. This is from last year.

Question of the Week – Loose Smut

Posted by romeethredge on April 17, 2015

Last week I had a photo of some oats with a black powdery look where the grain should be. This is a disease called loose smut. You’ll often see this disease in very very low levels. I’ve seen it at higher levels where someone saved their own seed for several years and didn’t use a systemic seed treatment.

It also occurs in wheat and here’s an excerpt from the UGA Wheat production guide about it.

“Loose smut causes the tissues in the head to be replaced by masses of powdery spores. The fungus spores invade the embryo of the developing seed and the fungus survives there until the seed germinates.  These smut pathogens are only transmitted by seed. Planting certified seed is an effective method to control smut diseases because seed fields are carefully inspected. Seed treatment with systemic fungicides is an inexpensive way to achieve nearly complete control of loose smut.”

This week someone brought me this monster to identify. What is it?

Peanuts Cracking the Ground

Posted by romeethredge on April 17, 2015

IMG_6208

A few peanuts were planted last week and they are just cracking the ground. These Florun 107 peanuts planted in twin rows were put in the ground a week ago here in Seminole County on a Tifton type soil.  This grower has about a thousand acres to plant so he got a hundred of them in the ground so far.

It’s very wet now so planters are parked, but we’ll be good to plant when it dries out.

Wheat Fungicide

Posted by romeethredge on April 17, 2015

There has been a fair amount of wheat sprayed with fungicide in the last 2 weeks. We are seeing some rust in some fields. Here’s Brad Thompson spraying some that they have that has just completely headed out. That’s the best time to spray for maximum protective effect. Here’s the link to UGA’s Wheat Rust in Georgia publication.

Stormy Weather on Corn

Posted by romeethredge on April 17, 2015

We had some driving rains and high winds this week, although they were spotty.  Some corn was blown sideways, as you see here.  I feel like it will recover quickly, however. We are at the V6 growth stage. I dug up a plant and you can see that it was planted deeply and has good underground nodal roots that kept these plants from falling completely. In a couple of weeks, by about V9, the above ground brace roots will be growing in.  We can advance 2 leaf stages a week with these good growing conditions.

Corn Update – Dewey Lee

Posted by romeethredge on April 17, 2015

Dewey Lee, UGA Grains Scientist, has this timely corn update for us.

“This year’s corn crop is developing much faster than the corn crop over the last two years.  In 2013 and 2014, we had much cooler weather the first 35 to 40 days of corn growth. Rainfall,though has been somewhat similar.   This year it’s been much warmer.  When I look at the average temperature between this year and the last two years during this time, many areas in the corn growing region of the state are 5 to 7 degrees warmer.  What does this mean?  It means that we need to pay much closer attention to the crop in order to be timely with our inputs, particularly, nitrogen applications.  If the crop enters into a V6 to V7 stage and is showing signs of nutrient stress, some yield potential will lost as the plants begin the process of setting the number of rows that will develop on the ear.  This occurs between V7 and V8/V9.  It takes time for a plant to recover from stress.  This year, it’s not unusual for a corn plant to advance one leaf stage in three days.  This would mean that in 6 to 7 days, the corn plant can go from a V5/V6 stage to a V7/V8 stage.

Notice the bottom leaves that are N deficient. Look at the striping in the new leaves.  These are showing signs of a N/S deficiency.

The plants in the picture have had 70 lbs N  plus 8 lbs of S at planting but it is easy to see a visible sign of nitrogen and/or sulfur deficiency.  As you can see, this corn plant is between the V5 and V6 stage and, in just a few days, will begin setting the number of rows per ear.  It is imperative that this field receive both N & S right away to prevent any further yield loss.  In sandy loam to loamy sand soils, its easy for nitrogen and sulfur to leach quickly through the profile and below the root zone.  In a case like this, nitrogen and sulfur should be sidedressed by the row quickly or 40 to 50 lbs N with a small % of S injected through the pivot on a per acre basis.

A tissue analysis taken at this time and ten days to two weeks later can tell a lot about how much of the applied nutrients are having an impact.  If minor elements or other elements are showing signs of dropping below sufficiency levels, then there is time to apply any needed nutrients either by ground or through the pivot.”

Carinata Field Day – April 28, 2015 Quincy, Fl

Posted by romeethredge on April 17, 2015

The University of Florida-IFAS-North Florida Research and Education Center is pleased to announce a Carinata field day on Tuesday, April 28, 2015. University of Florida along with its partners, Agrisoma and Applied Research Associates, are developing optimum varieties of, and best management practices for, Carinata, a crop with proven potential to produce drop-in biofuels. At this field day we will have presentations focusing on our on-going research efforts, potential of this feedstock in the region, research plot tours, and an opportunity to see large acreage production of the crop.

Please see attached flyer for the day’s agenda. We are requesting an RSVP for this event by April 23, 2015. When you RSVP please indicate if you will also be going on the field tour scheduled after lunch. Your timely response will help us make adequate lunch and transportation arrangements.

 Please feel free to contact us with any questions.

No Counter on Cotton This Year

Posted by romeethredge on April 17, 2015

Dr. Bob Kemerait gives us this news concerning Counter nematicide use.

” I received official word from the Georgia Department of Ag that the EPA has denied our request to use Counter 20G on cotton.  (It is still legal on field corn.)  The reason given basically says that use on cotton would exceed the appropriate amount for the “risk cup” for terbufos (active ingredient) in the state.

  So, I am disappointed with this decision but I truly appreciate the efforts of Commissioner Gary Black, the Georgia Department of Agriculture, Mr. Richey Seaton and the Georgia Cotton Commission, Cotton, Inc., and also AMVAC for their efforts to provide cotton growers in Georgia with a tool to manage nematodes.

 However we must respect the decision by the EPA.  To be very clear, Counter 20G applied to cotton in 2015 is an illegal application.”
