Drift
Injury on Soybean and
Interactions with Scheduled Postemergence Herbicides
As fields of small grain, sugarbeet, and corn recover
from wet conditions, you will quickly see spray rigs
actively treating fields with herbicides.
Soybean is very susceptible to
drift from plant growth regulator (PGR) herbicides used in
many tank mixes.
Rapid
Corn and Soybean Growth is matched by “Weed” growth!
Consider corn growth stages when making
postemergence
herbicide choices.
Corn and soybean growth is now accelerating because of the
recent warm and wet weather. While the recent weather has
been more favorable to the growth of corn and soybeans it
also has been just as favorable to the growth of weeds.
The prolonged period of rain in May and June has prevented
timely application of postemergence herbicides in many
corn fields for the control of weeds. By the time
conditions allow field work, corn may be beyond the
optimum size for postemergence applications.
Fusarium Head Blight of
Wheat
FACTS ABOUT FUSARIUM HEAD BLIGHT (FHB, SCAB) OF
WHEAT
Major Armyworm Flight Detected
in Blacklight trap
Captures at Crookston
The blacklight trap at Crookston recorded
significant moth captures recently.
In the past, blacklight trap catches this high have
been an indication of a major flight creating a high risk
of an armyworm outbreak.
Scout for Diamondback Moth in
Canola
If you are planning to spray fungicide for sclerotinia
control, you may want to scout your fields and decide if
you want to add an insecticide to control diamondback moth
larvae.
Summer Seeding For Forage Crops
Establishment of a productive stand is a major hurdle
for many forage producers. Weed control is usually a major
problem for those who seed in the spring. The competition
of weeds for nutrients and moisture can be substantial.
Late summer seeding is an option that may improve the
probability of achieving a productive stand.
Supplemental N for Spring Wheat
Excessive rainfall throughout northwest Minnesota in
late May and early June has raised serious questions about
loss of available N applied in the spring wheat crop.
Consequently, there are questions about potential benefits
from in-season application of N.
