Rainfall
Continues to Affect Region
Rainfall in northwest MN and eastern ND continues to be the big
newsmaker. In the southern end of the Red River Valley, standing
water in fields continues to plague many locations as natural runoff
is hampered due to many drains and river channels already above
flood stage.
Fungicide Timing For Scab Control
Research has shown that fungicides can be effective in reducing
Fusarium Head Blight (Scab) severity and vomitoxin (DON) in small
grains when conditions are favorable for scab development and if
applied in a timely manner. Winter wheat has reached or is fast
approaching the optimum stage for applying fungicide for scab
control.
Small
Grain Disease Outlook:
Commentary from June 18, 2007
Steady rain is causing field flooding in many locations in
the Red River Valley. Yield potential may decline with extended
periods of soil saturation. If the wheat yield potential is worth
protecting from Fusarium head blight, now is the time to consider
your options.
Sclerotinia of Canola Risk Forecast
for Minnesota and North Dakota - June 18, 2007
An analysis of weather data and the top zone (0 to 4 inch) soil
moisture for the canola producing areas of North Dakota and
Minnesota for the 10 day period ending June 17th 2007, indicates
that there is a projected moderate risk of sclerotinia over much of
Minnesota and North Dakota, as indicated
in the risk map.
Whoa! Major
Armyworm Flight Detected
with Blacklight Trap Captures
Very high light trap
captures have occurred over the past few days at Lamberton and in NW
MN. Migrating moths have moved northward along the front that has
been parked along the Minnesota, North and South Dakota borders last
week.
Soybean aphid - Still Quiet in the NW
The third week in June is normally when we can begin some
expeditionary scouting for soybean aphid. Check a few of the fields
that are normally infested early if you haven't already done
so. Check field edges near buckthorn. If aphids are found, they are
likely to be in the expanding leaf at the growing point of the
plant.
Getting to the Root of the Matter
When we talk about crops and crop production, our discussions
seem to gravitate towards the plant parts that we can see – the part
that is above ground. However, at least half--and often much
more--of every crop plant is invisible. This portion consists
entirely or largely of roots which extend far into the soil profile.
Does
organic matter really matter ?
Ask any farmer which field he would choose if two are similar,
except one had a higher soil organic matter content. Chances are he
would choose the one with the higher organic matter.
