Wheat Update

If you did not get ¾ of an inch or more of rain in the last week you may need to water. Dig down 2″ and if the soil does not hold shape when balled in your hand, then water. It is best not to water when flowers are visible on more than 25% of wheat heads (FEEKES 10.5+);  just wait until flowers fall off (about 3 days later). You need ¾” to 1” of water (rain or irrigation) every week until 75% of wheat heads in your field are at Soft Dough Stage. Do not over water wheat.

Today, I think wheat (AGS 2035) planted on time is 4-5 days ahead of last year. Most wheat is at Feekes early 10.2 or older. This means the wheat head is visible in the leaf seath. (AGS 2035 planted 11-24-2014 in Seminole county is at Feekes 10.2 to 10.4) You need to spray as late as possible per the label of fungicide used, because most fungicides do not translocate well in the plant. We need to protect the head of wheat and the flag leaf during this time. If you see rust call me. I have seen very little rust but lots of Septoria, Stagonnospora leaf blotch, Powerdery mildew, BYD and Tan Spot.

FungicidesAbsolute 500 SC, Headline, Stratego, Quilt, Quadris, Folicur+Tilt, or one of many others.

All should be put out at per the label of fungicide used.

Aphids are out, but you need to have 10+ per flag leaf before you treat. Always watch for beneficials. Lady bugs, Aphid lions (lady bug larvae), parasitic wasp, and syrphid fly larvae all eat aphids.

Foliar insecticide treatments for aphid control: A well-timed insecticide application of a persistent pyrethroid insecticide such as lambda cyhalothrin (Warrior, Karate, Lambda, Silencer, others) can reduce the incidence of BYD and increase yields.  Lambda cyhalothrin can only be applied twice to a crop so use another product at heading such as Baythroid XL or Mustang MAX/Respect.  These can be combined with a foliar fungicide application and also will control cereal leaf beetle if it is present.

As always, follow all label instructions.

 Good Growing!

Wheat Update

Most wheat is at Feekes scale 10.1 or older, this is often called the early heading stage. At this growth rate wheat is about 3-5 days behind normal heading date. You need to spray a late as possible per the label of fungicide used, because most fungicides do not translocate well in the plant. We need to protect the head of wheat and the flag leaf during this time. You may want to add an insecticide to help control aphids and stink bugs. The picture below is a stink bug on the head of triticale in an oat field.

Fungicides

Headline, Stratego, Quilt, Quadris, Folicur+Tilt, or one of many others.

All should be applied per the label of fungicide used. Most full heading (10.3) should occur before April 1, 2013.

Soybean Grower Update

I have had several calls about growers with no or very little pods after the plant started blooming. The soybean plant has a main bloom stem that will bloom out first, if no or few pods are set then an auxalary bloom node (at the base of each joint) will form blooms. Often during any type of adverse weather the pods and blooms will abort, this is normal. The soybean plant will continue to make blooms and try to set pods until the growing season is over or the plant/nutreint yield threshold is met.

Please spray with a good fungicide.  One spray per season is usually enough.  A good fungicide has proven to give a yield increase of 6-8 bu/acre over non-treated soybeans in university test. ( R-3 = Pods at least 3/16 inch on the fourth node from top of plant )  This usually occurs about  7 to 10 days after full bloom. You lose some effectiveness if you apply too early. To control  velvetbean caterpillar and make loopers and stink bugs less of a pest add Dimlin. This year appears  to be a very bad stink bug year.  Look close at your soybean, cotton, and peanut fields especially if they are close to a harvested corn field because there has been several generations in your corn already. If you have stink bugs think about putting in some pesticide.  Watch for Kudzu bugs; I have found them in every field.

Soybean Update

All  area’s have had too much rain. This type of weather brings on plant disease and a tropical storm could bring soybean rust  to your fields.  My advice is to spray with a good fungicide.  One spray per season is usally enough.  A good fungicide has proven to give a yield increase of 6-8 bu/acre over non-treated soybeans in university test.  A good funcicide applied at the R2-R3 stage did a very good job last year (R-3 = Pods at least 3/16 inch on the fourth node from top of plant ). This usually occurs about  7 to 10 days after full bloom, soybeans planted in  mid MAY are now in R3.  You lose some effectiveness if you apply too early. To control  velvetbean caterpillar and make loopers and stink bugs less of a pest add Dimlin. This year appears  to be a very bad stink bug year.  Look close at your fields – cotton, peanut, and soybean – especially if they are close to a harvested corn field because there has been several generations in your corn already. If you have stink bugs think about putting in some pesticide.  Watch for Kudzu bugs I have found them in every field. For Information go to: http://www.kudzubug.org/grower.html

Wheat Update

Wheat has gone through a lot of weather change in the last 10 days. Most wheat should be coming out of a water logged state (see photo below). This week will give a a really big change in the way your crop looks.

Water logged wheat. Picture taken by Travis in Madison, FL.

Now is the last chance to top dress before jointing (you are really three weeks late). Think about mixing 1,000 lb. of UREA and 1,000 lb. of Ammonium Sulfate per ton. This will make a 35-0-0-12 sulfur. This is a great top dress for any small grain. With the rainfall we have had most of the Nitrogen and sulfur you applied has leached out of the current shallow root zone. It is still there but the roots need to get deeper to reach the N.

If you are concerned and have already put out 95 to 110 lb. of N, then please wait until the soil dries some and the plants send up flag leaves. This will probably be around April 1.

Tissue test your FLAG leaf, do not get the largest in each plant as it will get the first choice of N in the plant and give you a reading on it only. I prefer to get one from the smaller tillers because that is where your yield will be increased. These smaller tillers will dry up if you do not have proper fertilization.

Good Growing!

Wheat Insects Update

David Buntin, professor of entomology at the UGA-Griffin Campus, sent me an email a while back and I thought I would share.

“With the extended warm weather folks should also be checking for aphid (dueto BYD transmission).  If aphids are present or if farmers are going toapply a herbicide to wheat they may consider adding a lambda cyhalothrin insecticide (like Karate Z) or gamma cyhalothrin (Declare) to the tank mix. Other insecticides may reduce the aphids but the cyhalothrin products do abetter job of also suppressing BYD.”

Good Growing!

Wheat/Oat Grower Update

Take time to walk your wheat fields while the wheat is still young and you can count the plants per foot per 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.

If your wheat is 4 inches (two 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 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.

Please do not use 2,4-D at this time I think it hurts wheat yield too much and does not control all weeds.   Chemicals below are very gentle on wheat and give a much broader window of control.

Ryegrass has been growing also. Look at your fields and use the chemical that best suits your growth stage of wheat and ryegrass. PowerFlex is a good choice.

Weed control

Harmony Extra TotalSol: 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:  Per label gives excellent weed and ryegrass control. Read label for plant back restrictions.

Good growing!

Wheat Update: watering & fungicides

If you did not get ¾ or more inch of rain in the last week you may need to water.  Dig down 2 inches and if the soil at that depth does not hold shape when balled in your hand, then water.  It is best not to water when flowers are visible on over 25% of wheat heads, just wait until flowers fall off (about 3 days later).  Then ¾  inch rain or irrigation a week until soft dough stage in 75% of wheat heads. Do not over water wheat.

Today, I think on time planted wheat is 14+ days ahead of “NORMAL” years. Most wheat is at Feekes early 10.1 or older this means the wheat head is visible in the leaf seath. ( AGS 2035 planted 11-26-2011 in Seminole county is at Feekes10.5.3 to 10.5.4  flowering is over)  You need to spray as late as possible per the label of fungicide used, because most fungicides do not translocate well in the plant.  We need to protect the head of wheat and the flag leaf during this time.   If you see rust call me.

Fungicides:Headline , Stratego, Quilt, Quadris, Folicur,   Tilt , or one of many others. All should be put out at  per the label of fungicide used.

Aphids are out , but you need to have 10+ per flag leaf before you treat. Always watch for beneficials.  Lady bugs, Aphid lions (lady bug larvae), parasitic wasp, and syrphid fly larvae all eat aphids.

Wheat Update: insect control

Most wheat and oats could use rain or irrigation now. Small grain planted on time  from Griffin Ga., south is entering the Feekes 10.1 stage or later (see Chart)  wheat head just poking through leaf sheath.  With wheat still over $6.00 on the CBOT it will pay to use one of the mixtures like Quilt, Stratego, Twinline, Propicanazole+Tebuconazole, or Headline should be used.  Add Aphid control if needed. (see Insect Control here).

You need to apply this spray between Feekes 10.3 and 10.5 for best head disease control.

Dr Steve Harrison, wheat breeder at LSU has an update (click here to view) that gives the best explanation I have seen on why we have such ragged wheat this year. Please take time to read this it will help you in planning you wheat planting this Fall. Land Grant Wheat breeders (UGA, LSU, NCS, UF, and UArk) have several hundred varieties that are tested each year for our areas climate and disease pressure.  They really need to be thanked for all they do for the Southern Farmer.

Wheat Update: powdery mildew, leaf blotch & aphids

Powdery mildew, Leaf blotch and Aphids are causing problems on wheat this week.. The 80 degree days and nights around 58 degrees will really allow diseases to infect this wheat crop.

The photo above shows mildew and possible leaf blotch (Morris Henry). It is a good example of what you could see in your fields this week. Also you can see the effects of early heading caused by the extremely warm weather after enough cold hours have been acquired by the wheat crop.  Propiconazole or Tebuconazole at the low rate should cure your mildew and leaf blotch problems.  Do not spray your primary fungicide until the wheat heads, around Feekes 10.4 is best.

The aphid photo (above) is a good example of what you found last week in your fields and shows a colony growing and getting ready to fly to another area in your field spreading Barley Yellow Dwarf which can hurt your yield. A lambda insecticide will cure that problem.
