LITTLE ROCK — The Environmental Protection Agency said Tuesday that it was seeking
to cancel registration for a key insecticide used to combat crop-hungry pests such
as fall armyworm and corn earworm.
At issue is flubendiamide, an insecticide commonly known as Belt, made by Bayer Crop
Science product. It’s also known as Tourismo, labeled for tree fruits and grapes,
and Vetica, labeled for strawberries and squashes, made by Nichino America. The insecticide
has been labeled for use in more than 200 crops, including row crops, pistachios and
Last month the Environmental Protection Agency has asked two manufacturers to voluntarily
cancel uses of four pest control products containing flubendiamide, including Belt,
made by Bayer Crop Science.
The move follows a Jan. 29 effort by the EPA to get Bayer and Nichino America to voluntarily
cancel registration for the insecticide, which was rejected.
Gus Lorenz extension entomologist for the University of Arkansas System Division of
Agriculture, said Belt is currently the “go-to” product for controlling caterpillar
pests in soybeans and other crops.
“It’s been the major product used for control of soybean caterpillars for a long time.
So boll worms or corn ear worms, and soybean loopers, the army worm complex — all
those pests, we use Belt for control."
The EPA initially issued a temporary registration for Belt in 2008, which was contingent
on the findings of long-term studies on any adverse affects of the insecticide. According
to an EPA statement released Tuesday, several studies indicated the product may be
toxic to benthic invertebrates, part of the aquatic food chain.
In response to the EPA’s request for voluntary cancellation, Bayer issued a statement
Feb. 5, publicly rejecting the request, explaining that Bayer “believes the methods
used by the EPA exaggerate environmental risk and would deny farmers access to a critical
pest management tool.”
Out of reach
Lorenz said the second most commonly used insecticide to control caterpillar pests
in crops is Prevathon, a DuPont product. Both Belt and Prevathon belong to the diamide
class of insecticides, a fact that Lorenz said may put both out of reach for growers
in the state and elsewhere.
“It only stands to reason that if there’s an issue with Belt, there might be a similar
issue with Prevathon,” Lorenz said. “Between the two products, you can account for
about 90 percent of efforts to control caterpillars in soybeans, as well as grain
sorghum, corn, and to some degree, cotton.”
Lorenz said the current label for Belt is still active, and the product is legal to
use in Arkansas. If both Belt and Prevathon become illegal or unavailable, growers
will still have access to several other insecticides that can control caterpillars,
Lorenz said, although none of them are known to be as effective.
“We have a limited number of insecticides that are still reasonably effective for
control of caterpillar pests,” Lorenz said. “But these two products are extremely
efficacious, and have longer residual control than most of the other products currently
“There’s a reason why they’re the product of choice — it’s because they’re very safe,
with low mammalian toxicity — not toxic to off-target organisms, specifically us,”
he said. “There’s been no impact on honey bees, and other than the benthic organisms,
there’s been very little indication that there’s any off-target issued.
“We don’t have any other products outside that class that provide quite that level
of control. So that’s a big concern,” Lorenz said.
