If your wheat/oats are 4 inches (three or more tillers) tall or taller then you may need to put out your winter weed control. The weeds have really been growing because of the warm weather, and also can really hurt your yields. Chemical prices are up this year so please don’t cut out application because of the price, it will pay to control the weeds.
Take time to walk your wheat fields while the wheat is still young and you can count the plants per foot of row. If you find a row that is too thin or too thick flag that row on your drill and correct the seeding rate before you plant next year. A count of 18-20 plants per foot (7-8 inch row) is great, 25-30 is way too thick.
(See Small Grains 2014 from UGA)
Harmony Extra SC, per label always add surfactant per label.
Express Plus MCPA, per label always add surfactant per label. Gives good to excellent control on most winter weeds. DO NOT USE THIS ON OATS.
POWERFLEX and others, per label gives excellent weed and ryegrass control. Read label for plant back restrictions.

The below paragraph was taken from Seminole Crop New.
It was a cold March. Here is the info from our Donalsonville Weather station that shows we had an average low of 42.7 degrees F. and the long-term normal is 47 degrees. The average daily low last March was 56.3, so 13 degrees different. March was cooler than January this year… January average temperature was 57.6 about 3 degrees warmer than the March average temperature. Go to http://www.georgiaweather.net/ for more info.
The photo below shows freeze damage. This was on early maturing wheat planted at the correct time. Also we have aphids (2nd photo below), kudzu bugs, and stink bugs in most wheat fields. Looks as if we are in for a bad year on insects; a warm January really allowed the insects to survive.

Spray your wheat with a fungicide at the Feekes 10.1 (if label allows) stage and add an insecticide to the tank mix – it will pay off.
*Follow label on all Pesticides, rinse and dispose of empties properly. Info Georgia Pest Management Handbook 2013
A low area in a field in Plains taken on Monday.
Some of the stems are freeze damaged and will not recover. Other tillers of the same plant will make wheat and this area will suffer some yield loss. This was a small low area and the rest of the field had very little damage.
I have checked oats and wheat from Plains to Donaldsonville and found damage only in the low areas, not in most of the field. It appears damage occurred more from Camilla North. At this time I think we have a very good wheat crop. This will change if we get another cold snap.
The second photo is of Power Flex on large radish. Weeds can and will hurt your yields if not treated.
Thanks to Kevin Alford for the photo.
To make the most of your fields check for winter weeds and please consider using Harmony TotalSol or Power Flex. Wheat and WEEDS will grow a lot in the next week as weather continues to warm .
Please do not use 2-4-D this late in the growing season.
