Evaluating Hail Damage to Soybeans
Recent severe weather events across the Midwest have left crops in
many parts of Minnesota affected by hail damage. Assessing hail
damage to soybeans in early June can be a bit tricky, with many
variables to consider on your way to making a final decision to
replant or maintain the existing stand.
Evaluating Hail-damaged Corn
A band of hail passed through east central Minnesota last week,
damaging corn fields in Sibley and Nicollet counties. Area corn
plants lost 50 to 100 percent of their leaf area due to the storms.
How
Long can Crops Tolerate Flooding?
The severity of crop damage from flooding and ponding depends on
the depth of the water, the length of time flooded and the
temperature of the flood water.
Limits for Postemergence Corn Herbicides
Once again, spring’s cold weather and the frequent showers are
delaying plant growth and field activities. Eventually, weather will
improve and things will start growing. Here are summary tables for
corn herbicides since it is important to keep track of the right
timing to apply postemergence
Wheat
Disease Risk Models
Begin monitoring wheat disease risk models regularly to help
with crop management decisions. The models available on the web
provide an overview of risk based on environmental conditions and
the biological requirements of the pathogen.
Alfalfa Weevil Update
Sweep net sampling (in between rain showers) has found the first
small larvae of alfalfa weevil present in the fields in the southern
end of the valley. Further north, degree days suggest there is still
a little time before hatching of eggs is underway (300 DD for
hatch).
How
Well Did Soybean Aphid Survive the Winter ?
Overwintering success of soybean aphid has been monitored for the
last three fall-winter-spring in northwest Minnesota. The goal of
the project is to determine how well aphids colonize buckthorn in
the fall, determine egg laying success of the population, and
monitor egg hatch and aphid migration in the spring.
Hiring a New Employee on the Farm
Finding quality employees that will fit well into you farming
operation can be a difficult task. In recent years the strong
economy had attracted many people to the larger cities and away from
the rural areas. Recently, good jobs have been more difficult to
acquire and we seem to have more work force available in the rural
areas.

Management Field School
Thursday, June 19, 2008
NDSU Carrington Research Extension Center, Carrington, N.D.
This field school is targeted toward crop advisers, but also is
beneficial for farmers. The school will provide hands-on training in
crop, crop pest and soil management using field demonstration and
research plots.
