Wheat Grower update

03-30-2018

 

Wheat is  flowering from Tifton, GA south and should flower in Plains next week . Wheat gets FHB or SCAB during this flowering time from rain events.

Please use Caramba, Proline, or Prosaro at labeled rates . This approach should decrease your exposure to FHB while keeping the other diseases in check.

 

Foliar insecticide treatments for aphid and stink bug control can be added per label. A well-timed  insecticide application of a persistent pyrethroid insecticide such as lambda cyhalothrin (Warrior, Karate, Lambda, Silencer, others) will kill aphids and increase yields.

Wheat Grower update

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.

 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.

A spray at Wheat Flowering will be one of the most important tools a wheat grower can use in 2017. Wheat should be  flowering from 03-25-17 to 04-10-17. Wheat gets FHB or SCAB during this flowering time. 

Those of you who went to the Small Grain Soybean Expo in Perry today could have heard from Christina Cowger, Small Grains Pathologist USDA-ARS on this problem that has cut our yields in half and ruined the quality of our wheat for the last two 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 the chart below on fungicides and CHOOSE WISELY for FHB control. Below you will find what we have been doing wrong in the past years to control FHB.

FHB SPRAY UPDATE

FHB SPRAY UPDATE

04-11-16

In the link below, you will find a photo of wheat flowering and a slide of best time to spray for FHB control.

FHB Spray best time

5-7 days after your wheat strarts flowering, (this should occur around 04-12 to 04-20) put out Caramba, Proline, or Prosaro. (make sure your dealer has product in stock for you) This approach should decrease your exposure to FHB (not complete control, to get better you will need a wheat with the FHB gene and apply the fungicide) while keeping the other diseases in check.

Wheat/Oat Grower Update

Please see correction on timing of FHB spray from Christina Cowger, last update was in error.

Important note from Christina: If scab is your target, you will only profit significantly if you apply fungicide between early flowering and up to 7 days later. Fungicide applications before flowering will give little to no scab control. This is because the scab fungus attacks the heads through the flowering parts (anthers) once they are extruded.

Bottom line: use Propiconazole or Tebuconazole to correct any early problems. Then, if there is medium to high risk of scab, which you can see at the forecasting site www.wheatscab.psu.edu, put out Caramba, Proline, or Prosaro at early flowering or, if it is too wet then, up to 7 days later. This approach should decrease your exposure to FHB while keeping the other diseases in check. I will be sending out FHB update as soon as I prior to wheat flowering.

Wheat Update

These photos were taken today (4/19/15) south of Blountstown, Fl.  I have never seen a field so completely covered with rust and septoria. This could happen to your fields if you did not spray on time. At first I thought Wheat Take All, but this is the first I have seen wheat in this field. It was following peanuts. This field has had rain for several days straight.

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.

Fungicides

Absolute 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.

Always follow all label instructions.

Good Growing!

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.
