Soybean Rust Status Through August 11, 2008
Since January of 2008,
soybean rust has been reported in two counties in Alabama; one
county in Georgia, 16 counties in Florida; three counties in
Louisiana; one county in Mississippi, and four counties in Texas.
Rust was also reported in three states (five municipalities) in
Mexico on yam bean and soybean. These were destroyed or are no
longer active infections.
Glyphosate Resistant Weed Survey:
Do you have a RR soybean field with suspicious
broadleaf weed escapes?
The University
of Minnesota Extension and North Dakota State University are
collaborating on a survey of RR soybean fields to evaluate possible
resistance to glyphosate in broadleaved weeds that have survived
herbicide treatment.
Glyphosate Control Concerns Come Closer to
Home
On August 5, sugarbeet growers and industry representatives toured a
plot near Mayville, North Dakota where common ragweed is proving
difficult to control with glyphosate.
Soybean Aphid Update:
Never Walk Away
Nope, I'm not talking about the new song from that venerable and
aging rock band Journey. Lots of fields
that were treated earlier in the year for soybean aphids are being
ignored. With seasonal aphid movement underway and good
environmental conditions for reproduction, it would be a mistake to
assume fields treated earlier in the summer will remain aphid free
for the remainder of the season.
