Ground Application of
Fungicide for the
Suppression of Fusarium Head Blight
The North Dakota State University Extension Service
has a new publication to help small-grain producers fight
Fusarium Head Blight. The publication
describes the latest research and includes
recommendations on the most effective application
techniques.
Water Use by Small
Grains
For high yields, small grains need 14 to 17 inches of
water, depending on weather conditions and length of
growing season. The water used for optimum growth is a
combination of stored soil moisture, rain and sometimes
irrigation.
Small Grain Disease Update
(06/13/06)
Small grain disease outlooks based on risk models
continue to be encouraging. In general, current weather
conditions would suggest the risk for Fusarium head blight
(scab) are low. However, rainfall, such as occurred on
June 11 and 12, would place
susceptible wheat varieties at moderate risk. It is
important to begin monitoring growth stage of fields and
check for model updates on a regular basis as local fields
reach the boot to heading stages.
Cereal Aphids: Worth
Watching
As small grains reach the flag leaf - boot - heading
stages, we focus on cereal aphids and the plant diseases
that could impact yield and quality. Field scouting
activities this week did locate aphids, but the news isn’t
all bad.
Iron Deficiency
Chlorosis (IDC) in Soybean
Yellowing of some soybean plants (IDC) can be seen in
a number of soybean fields in the region. Although there
is sufficient iron in most of our soils for plant growth,
the soybean plants displaying the yellowing have
difficulty taking up the iron during this early stage of
growth (first and second trifoliate just expanding).
What’s Happening with
Soybean Rust ?
Scouting has intensified in soybean sentinel plots
especially in the south. Most of the soybean sentinel
plots have been planted throughout the country with plants
in some early planted plots starting to reach maturity.
Scouting continues on kudzu patches from Florida to the
north as far away as Nebraska.
Risk Forecast for
Sclerotinia of Canola in
Minnesota and North Dakota
are now
available
Sclerotinia risk model for
canola is now being updated regularly through the Northern
Canola Growers website.
Rust Infections
Observed in Ryegrass Seed Production
Rust infection on the leaves in ryegrass seed production fields near
Baudette and Roseau have been reported by producers and agronomists. The first
observation of rust in ryegrass of the 2006 season was observed on the afternoon
of 6/5/06.
2006 Annual Grass Seed
Plot Tour near Roseau
Wednesday
June 28, 2006
The annual Grass Seed Plot Tour will take place
near and at the Magnusson research site northwest of
Roseau on Wednesday June 28.
