Oat Planting

Posted by romeethredge on October 16, 2014

We’ve been talking about oats for grain. It’s too early to plant it now if you want to harvest the grain. Some folks want to grow some for seed for the following year. We need to wait until close to Thanksgiving for that because if we plant it too early the heads will shoot up when we will be having some hard cold and they will be damaged.

Of course lots of oats are being planted now for grazing and that is fine. We had problems with caterpillars and seedling disease in the past few weeks but we are hopefully past  the worst of that now.

Here’s a good UGA publication available on the web concerning Southern Small Grains http://extension.uga.edu/publications/files/pdf/B%201190_2.PDF  and it has a good section concerning Oats with the following valuable planting  chart.

Cotton Picking Time

Posted by romeethredge on October 16, 2014

Lots of cotton being picked now, finally. It looks ok, not a tremendous crop but pretty good, it seems so far. We think it would have been better, except for the excessive rain the first 2 weeks of September. Dryland suffered due to the summer drought and then when it was opening all our cotton got too much rain.

Some areas will have good dryland yields due to the spotty rains.

Here’s some irrigated cotton that is doing well.

Question of the Week – Tobacco blooms

Posted by romeethredge on October 16, 2014

Last week I had some Tobacco blooms in the photo I asked about. I took the photos at the Museum of Agriculture (formerly Agrirama) in Tifton. Here’s another shot.

This week I saw these in some soybeans. What are they and should we be worried or glad to see these in the soybeans? See the tiny spaceships they arrived in?

Late Leafspot a Problem in Peanuts

Posted by romeethredge on October 9, 2014

We are seeing more and more late leafspot in peanuts. Here’s a field of irrigated Ga o6G peanuts that are 125 days old. They have been sprayed with fungicides all season but we have a problem. We’ve lost most of our leaves to the disease.

 

_DSC8976 _DSC8979 _DSC8983 _DSC8984 _DSC8987

 

Management Points for Leaf Spot, UGA Peanut Production Update 2014

1. Practice good crop rotation.

2. Destroy any volunteer peanuts that may grow in a field and bury/remove old peanut
hay that can serve as a source of spores for leaf spot diseases.

3. Do not delay the start of a leaf spot fungicide program.

a. When using chlorothalonil (e.g. Bravo Ultrex, Bravo WeatherStik, Echo,
Equus, or other generics), Tilt/Bravo, Echo-PropiMax, Stratego, Elast 400F,
Eminent 125SC + Echo, or Headline (at 6 fl oz/A), and you have adequate
crop rotation, your first leaf spot spray will typically be applied somewhere
between 30 and 35 days after planting (unless weather has been dry and
unfavorable for development of foliar diseases.

b. In fields where risk to leaf spot has been calculated as low-to-moderate, we
have maintained good control of leaf spot when using a single application of
Tilt/Bravo (2.5 pt/A) 40 days after planting

c. Growers who use the AU-pnut forecasting system, automated at
http://www.AWIS.com, can more effectively time their first application based upon
environmental conditions.

d. If you are planting peanuts after peanuts, you will likely need to begin your
leaf spot program earlier than 30 days after planting because of the increased
risk of disease.

e. If you are using Headline (at 9 fl oz/A) for your first leaf spot spray, it is
appropriate to combine your first two fungicide applications for leaf spot
control (for example at 30 and 44 days after planting) into a single application
of 9 oz of Headline at 38-40 days after planting.

4. Traditionally, fungicides are applied on a 14-day calendar schedule beginning after
the first application. This 14-day interval may be modified for reasons such as those
below:

a. The interval should be shorter than every 14-days if conditions:

i. Rainfall has been abundant and conditions are favorable for leaf spot.

ii. You are using the AU-PNUT leaf spot advisory and it calls for an early
application.

iii. Peanuts follow peanuts in a field and leaf spot is expected to be
severe.

iv. Rainfall came on quickly after your last leaf spot spray and you are
concerned that some of the fungicide may have been washed off the
plants in the field too quickly.

v. You are planting a variety that has poor resistance to leaf spot
diseases.

vi. Peanut rust appears in your field prior to the end of the season.

b. It may be possible to extend the spray interval beyond 14-days if:

i. Conditions have been dry and unfavorable for leaf spot, especially if
you use the AU-PNUT advisory for spray guidance.

ii. You are using a variety with increased resistance to leaf spot. For
example, if pressure from soilborne diseases is not severe, the spray
interval for such varieties could be every 21 days and it is possible to
treat the most resistant varieties only three times during the season.
(Additional information can be obtained from your local Extension
Agent).

iii. You use Peanut Rx and determine that the predicted risk of
fungal disease in a field is low to moderate and rainfall has not
been excessive since your last spray (additional information can be
obtained from your local Extension Agent).

iv. Since many fungicide applications are used to manage leaf spot
diseases and soilborne diseases, one must consider the effect that an
extended spray schedule would have on both types of disease (foliar
and soilborne) BEFORE shifting from a 14-day schedule.

Question of the Week – Salvinia (Water fern) and Duckweed

Posted by romeethredge on October 9, 2014

Last week I had a photo of 2 floating pond weeds I was asked about in a cypress pond here. Jimmy Clements answered the question correctly, they are Salvinia aka Water fern and Duckweed.  This Salvinia is not to be confused with the Giant Salvinia they have in other areas, like Louisiana. It is native to tropical America.

5 to 10 Triploid Grass carp per acre will help this pond problem after chemical control.

Here’s a link to UGA’s Dr. Gary Burtle’s Pond management info.

Univ of Florida has a good aquatic weed website you can link to here.

Texas A & M also has a good resource.

This week I have a photo of a crop bloom and I want to know what it is?  What is this crop?

Sunbelt Expo 2014, Oct 14 – 16

Posted by romeethredge on October 8, 2014

 It’s Expo time again in Moultrie Georgia and I remember my first trip there when I was a freshman at ABAC in 1981. Now my son is an ABAC freshman and I’m still learning at the Expo.  There are new things at the Expo every year and I was looking at the program and this year is no different. They will have UAV (Unmanned Aerial Vehicles) demonstrations for the first time this year. Go by the UGA Building for sure while you are there; there’s always something new to learn about and see there.

This link  below should take you to this year’s program. Which has lots of good articles including info about ABAC’s Scavenger hunt and an article about Dr. Ron Jones’ retirement as longtime member of the Expo Board of Directors.

Also there’s a great App for downloading to your smartphone to supply you with info about the Expo and when things are and where you are.

Here’s a link to a video about how to download it and what it will do.

Peanut Digging and Pickin’ full speed

Posted by romeethredge on October 7, 2014

It’s October , the driest month of the year, thank goodness. We have a lot of  peanut digging and picking and cotton picking to do. On average we get about 2 inches in October and we hope that will be the case this year. We’ve already received 1.74 inches at the weather station in Donalsonville.

Of course September is usually a dry month with an average of 4 inches over the years but this year we had over 10 inches. We’ve had a years worth of rainfall already (54 inches), we are 10 inches ahead for 2014.

Peanut Vine Condition

Two growers wanted me to see their peanut vine condition from a bird’s eye view so we could make better digging decisions, so I have some photos of peanut vines and harvest from a helicopter, thanks to Brad Thompson.

We have 2 main problems causing vines to degrade right now, late leafspot and nematodes. Also white mold is rough in some cases.

Generally we don’t want too dig a field early for any reason, and we want to look at the field as a whole and not concentrate on the worse spots, but many factors go into a farmer’s decision concerning when to dig and vine condition is an important factor.

_DSC8722 _DSC8720

Lots of digging is going on now.

You can pick a field pretty quickly with 6 of the 6 row pickers in the field.

Carinata

Posted by romeethredge on October 6, 2014

Carinata is a potential crop for the tristate area but the herbicide restrictions may not allow most folks to grow it.

Carinata is an oilseed crop that grows similar to canola, it is used in production of a biofuel that can be used in jet engines.
