TOMATOES
Tomato brown rugose fruit virus concerns US growers
By Stephen Kloosterman
Associate Editor
Growers and officials across the
country are watching produce aisles
for imported tomatoes with tomato
brown rugose fruit virus, or ToBRFV,
which they say could disrupt domestic
growers of tomatoes and peppers.
Although tomato seeds or plants
can contract the virus at any stage,
the symptoms often are not displayed
until the tomato turns red, said
Michigan State University Extension
Educator Ron Goldy. The virus was
first reported to be in tomatoes in
Israel in 2013.
" It's fairly new, and has moved
around since then, " he said.
Many tomatoes are shipped
green, and even many vine-ripened
tomatoes are not shipped fully red,
so it's possible for the virus to go
undetected until reaching grocery
stores, he said. While the virus isn't
harmful to people, visibly blotchy
fruit are unmarketable.
" It could be a real problem, and
we don't need another problem, "
Goldy said. " It's one more thing in an
industry that doesn't have a big profit
margin to begin with. "
Growers in many locations have
some degree of concern. The Florida
Department of Agriculture and
Consumer Services in early October,
reported it had recently identified
the virus in packaged, Mexico-grown
tomatoes. Florida officials found infected
tomatoes in Naples and Gainsville
and destroyed them. University of
California, Davis plant pathologist Bob
Gilbertson recently spoke to openfield
tomato growers about the virus.

the ToBRFV virus are a serious

threat to Florida, the nation's leading
producer of tomatoes and a $262
million industry in our state, " said
Florida Agriculture Commissioner
Nicole Fried. " We need the USDA
to step up, initiate tracebacks to
Mexican producers, and fulfill its
responsibility to protect American
growers and consumers. "
In November, Fred Leitz, a vineripened
tomato grower near Sodus
in southwest Michigan, saw a
blotchy tomato at a store, and he
contacted Goldy.
" If a grower sees it (ToBRFV) in
Michigan, he needs to buy it and get it
to Michigan State so they can test it, "
Leitz said.
USDA Animal and Plant Health
Inspection Service (APHIS) said it
will restrict tomato and pepper
imports that could be carrying
ToBRFV. The temporary measure
began Nov. 22, 2019.
" APHIS will require tomato and
pepper fruit imported from Mexico,
Israel and the Netherlands (countries
approved to export tomatoes where
ToBRFV is present) to be inspected
at the point of origin to ensure it is
free of disease symptoms, " according
to APHIS's order. " Because Canada
Although tomato seeds
or plants can contract
the virus at any stage,
the symptoms often are
not displayed until the
tomato turns red.
The virus is spread by seed as
well as by physical contact, Goldy
said. He's most concerned about the
infection cropping up at an industry
" bottleneck, " such as batch of seeds
or a greenhouse growing tomato
plants for transplant, that would affect
many growers at once. Unfortunately,
it's thought to be a " stable " virus,
meaning it could live on in the ground
for quite some time after infected
plants are destroyed.
If infection of the virus occurs,
Goldy said, control would be similar
to how growers currently deal with
tobacco mosaic virus or tomato
spotted wilt. Sanitation practices
for field workers, greenhouses and
equipment can help contain its spread.
" We have the tools and knowledge as
to how to handle it, " he said. VGN
