John Wilder sprays big clumps of blackberry with an
effective herbicide, lots of water and a big tractor.
Surmount also controls broadleaf weeds
and provides soil residual activity to control
weeds that germinate for weeks after spraying.
“In 2006, I sprayed berry vines and
persimmons and weeds I’ve never seen,”
Wilder says. “It did a good job. Some of
the persimmons came back, but there’s no

= 14 days and nights.
That’s how long Intrepid 2F insecticide controls
armyworms, including fall armyworms, southern
armyworms, beet armyworms and true armyworms —
pests that can chew up a pasture overnight.
Given the high value of intensively managed
forage, it makes sense to protect it.
Now, just in time for the 2008 season,
Intrepid 2F is labeled for use in pastures and forage
grasses grown for hay.
“Armyworms are ferocious eaters, and they can
come at you over a period of time,” says Ralph
Lassiter, Dow AgroSciences product technology
specialist. “So, having 14-plus days of residual
control, as Intrepid 2F does, can save you repeat
treatments compared with other insecticides.”
Intrepid 2F also puts a halt on armyworm
appetites quickly.
Intrepid 2F has a novel mode of action that
mimics the action of the molting hormone of
armyworms. Upon ingestion of the insecticide,
armyworms undergo an incomplete and lethal
premature molt. This process stops their feeding.
He has 3 rules
for better brush control.
John Wilder’s landlords depend on him
for more than just lease payments.
He defends their pastures from
encroaching brush that would turn their
tame grassland into the East Texas woods.
He’s gotten pretty good at it, too.
From the headquarters ranch he owns
at Tyler, Texas, Wilder operates mostly on
3,000 leased acres scattered around the area.
Those acres support a cow/calf herd and
a significant hay business. In pastures, he
continually fights blackberry, persimmon,
locust and other woody species.
“If we don’t do something, they’ll take
over a place,” Wilder says. “Cows won’t go
in these bushes. They stay away from that
stuff. And there’s no grass under these big
clumps of berry vines anyway.”
To control that brush,
