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.


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!
