Single-Generation
European Corn Borer Management . . .
Begin Scouting
The European corn borer (ECB) is still the region’s number one
insect pest of corn, though Bt corn has helped take much of
the guesswork out of management. The challenge of managing borers in
northwest Minnesota has always been due to the lengthy interval of
moths emerging from overwintering sites.
Wheat Streak Mosaic Confirmed in
the Red River Valley
Plants in the small grains disease management research site located
near Foxhome in west central Minnesota have leaf symptoms that
aren’t normally noted in the RRV. Scattered plants have yellow and
green leaf striping symptoms which have lead to
the confirmation of wheat streak mosaic
virus infections.
Musings On Iron Deficiency
Chlorosis (IDC)
According to Webster, to muse is to consider or to ponder. There
is probably no easy, simplistic answer. Iron Deficiency Chlorosis is
the end result of a complex combination of factors. So, let's review
what we think we know.
Crop Rotation and Legumes
Legumes in rotations will fix nitrogen from the atmosphere into the
soil. The amount of nitrogen fixed depends on the legume and the
management system. Dry matter accumulation for well-adapted legumes
seeded in the spring can range as high as 4 tons/acre, but more
commonly ranges from 2 to 3 tons/acre.
Coping with Drought Conditions
in Pasture
Dry conditions are not uncommon in much of our area, but this
spring and summer have been dryer that usual. Although the dry
conditions have an upside, such as less mosquitoes and great weather
to harvest hay, the drought is taking its toll on much of our
pasture and hayland.
