Wheat Grower update

02-16-2018

 

FHB is the problem that has cut our yields in half and ruined the quality of our wheat for the last three years. Rainfall or irrigation will increase infection if it occurs during the 5-6 days of Flowering.  Wheat growers MUST change their fungicides to control FHB.

Please look at labeled fungicides and CHOOSE WISELY for FHB control. Below you will find what we have been doing wrong in the past years to control FHB.

Strobilurins can actually increase vomitoxin (DON) relative to an unsprayed check.  This effect of increasing DON gets worse the closer you get to flowering, so it’s best not to apply a strobilurin-containing fungicide after flag leaf. That goes for pure strobilurins and also strobilurin-triazole mixes. Some triazoles are more effective than others at reducing FHB kernel damage and vomitoxin.  The best ones are Caramba, Proline, and Prosaro. Tilt and Folicur do some good, but not enough in a bad scab year.

Bottom line: use Propiconazole or Tebuconazole to correct any early problems.  When your wheat normally flowers Feekes 10.5 (see photo) and  up to 5 days after flowering put out Caramba, Proline, or Prosaro. This approach should decrease your exposure to FHB while keeping the other diseases in check.

 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) will kill aphids and reduce the incidence of BYD and increase yields.

 A spray at Wheat Flowering will be one of the most important tools a wheat grower can use in 2018. Wheat should be  flowering from 03-14-18 to 04-10-18 (Tifton, GA). Wheat gets FHB or SCAB during this flowering time.

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.

Wheat Update – Freeze Damage

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.

Good Growing!

Soybean Update

It appears this year will be a very bad stink bug year. If you put out an early spray you could help your soybeans and any other crops on your farm. Look closely at your cotton, peanut, and soybean fields; especially if they are close to a harvested corn field. There has likely been several generations of stink bug in your corn already.

Most areas have had some rain, but  we need much more. 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 usually enough.  A good fungicide has proven to give a yield increase of 6-8 bu per acre over non-treated soybeans in a university test.  A good fungicide applied at the R1-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  Early MAY are now in early 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. If you have stink bugs think about putting in some pesticide.  And watch for Kudzu bugs, I have found them in every field.

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.

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.  Always follow all label instructions.

Good Growing!
