Spring Broadleaf Weed Control in Wheat (1:08 minutes)
Audio/Video Script:
Susan Scott
County Extension Agent - Agriculture
Not many broadleaf weeds in wheat reduce yield or are quality concerns. This
is Susan Scott, County Extension Agent with the University of Arkansas, Division
of Agriculture.
Controlling key broadleaf weeds will increase harvest efficiency
and protect grain quality.
Garlic and onion complex reduce grain quality and are easily controlled with
the full rate of Harmony Extra. Buttercup, chickweed, mustards, mayweed and
shepherdspurse will also be controlled with Harmony Extra.
2,4-D provides more primrose control along with improved horseweed control
and adequate suppression of garlic and other broadleaf weeds.
Dr. Bob Scott emphasizes the importance on never missing a chance to kill
horseweed.
“If severe infestations of horseweed are present apply 1.5 pints of
2,4-D + 0.5 oz Harmony. Also remember the 2,4-D timing is after tillering but
before jointing. Do this for your soybean crop, as much as your wheat. It will
be much easier to treat the horseweed in wheat than to deal with glyphosate
resistant horseweed in-season.”
Read and follow label directions regarding tank-mix partners for ryegrass
control. For more information contact the Lonoke County Extension Office or you
local County Extension Agent.
