[Narrator] [Picture of pigweed] The University of Arkansas Division of
Agriculture is testing new tactics for defeating a difficult foe. [Picture of
Dr. Smith] Dr. Ken Smith, an extension weed scientist, says herbicide-resistant
pigweed has an Achilles’ heel: its short-lived seed [Picture of pigweed seeds].
Knowing that ninety-nine-plus percent of pigweed seed will be gone at the end of
four years, Smith is trying two new directions. [Video shows a tractor tilling –
deep tillage]One is deep tillage. The deeply buried seed won’t have enough light
to germinate. [Picture of a pigweed in a cotton field – zero tolerance] Another
tactic being field-tested this summer in cotton is “zero tolerance,” where
hand-hoeing and a supplemental herbicide will kill the pigweed before it can go
to seed. The tactic will eventually be tested in soybeans as well.
[Pictures of pigweeds in a field] Smith says this represents an important
shift in thinking for farmers. Instead of trying to kill weeds when they reach a
certain density that will result in yield loss, now they’ll try to eliminate
them before they make seeds.
