Farmers Watch for Soybean Rust

All eyes are on the south right now for signs of a potentially
devastating fungus that attacks soybeans. A serious outbreak there could
bring soybean rust to the Midwest – where most of the nation’s soybeans are
grown. The Great Lakes Radio Consortium’s Tracy Samilton reports:


Soybean rust spores are carried on wind currents, so it is easily spread.
So far this year, only Georgia has had a small outbreak.


Ray Hammerschmidt is a plant pathologist at Michigan State University. He
says every step is being taken to protect soybean crops, including dotting
the Midwest with what are called sentinel plots.


“And once a week, starting in a few weeks, each of these plots will be scouted very intensively, looking at at least a hundred plants, looking for any signs or symptoms of the disease.”


Advance warnings will allow farmers to apply fungicide to their crops as
soon as possible. Soybean rust can’t overwinter in the cold north.
So if southern states have good luck – or do a good job treating it – it’s less
likely to make it here.

Setting Traps for Emerald Ash Borer

The emerald ash borer has been destroying ash trees in Michigan, Ohio, Ontario, Virginia and Maryland – and the bug is spreading. Now, agricultural officials in Michigan are developing an early warning system. By detecting the insects early, they hope to slow or even prevent their spread.

The emerald ash borer has been destroying ash trees in Michigan, Ohio,
Illinois, Maryland, and Ontario – and the bug is spreading. Now,
agricultural officials in Michigan are developing an early warning
system. By detecting the insects early, they hope to slow or even
prevent its spread. The Great Lakes Radio Consortium’s Tracy Samilton
reports:


Forestry agents will be designating a number of so-called trap trees in
every township in Michigan. The ash trees will act as sentinels. A
strip of bark will be removed from the trees, which stresses them and
makes them attractive to insects. A sticky substance called tanglefoot
will then be applied to the trees to catch the borers. Kara Bouchay is
with the Michigan Department of Natural Resources.


“Part of the struggle with having a borer that you can’t see most of
time because it’s underneath the bark, is when it’s in a low level
population, it basically flies under the radar. So the trap tree is a
way to bring it to a single location to detect it.”


If borers are found on a tree, all ash trees within a half-mile will be
destroyed to contain its spread. Bouchay says if the early detection
system proves itself, it will likely be implemented in other states as
well.
