Red River
On-Farm Yield Trials and
Wheat Fungicide Research Plot Tours
A series of five plot tours to review the University of Minnesota’s
Red River On-Farm Yield Trials and Wheat Fungicide Research will be
held July 9 -16 , 2007 at locations throughout Minnesota’s
wheat-growing region.
Fungicide
on Wheat: To Spray or Not to Spray ?
This year wheat growers have and are asking if an early (4 to 5
leaf growth stage) and/or late (early flower) fungicide application
should be made. Early-season disease (aka: tan spot) is showing up
in locations that have had several days of rain.
Can We
Estimate the Potential Profit from a
Fungicide Application to Control Wheat Diseases ? *
Building upon the information provided by Hollingsworth and Holen on
estimated returns observed from actual fungicide trials conducted in
2006, there is a method that has been suggested for estimating
potential returns from a wheat fungicide program.
Small
Grain Aphids Update – June 11, 2007
Surveys in the region showed very low but relatively wide spread
populations of cereal aphids (mostly Bird Cherry Oat aphid). About
50% of plants sampled had aphids but the numbers are low
(~2-5/plant). The proportion of plants with aphids is rising and the
numbers in the SW MN and South Dakota are high.
Check
on Alfalfa Weevil Status in Fields
As we slog through the completion of our first cutting, check
alfalfa fields for weevil larvae. Larvae can usually be found in the
field for one to two months, generally during May and June. Mature
larvae move to the ground and spin a fragile, lacelike cocoon
attached to debris or the plant. A new adult emerges after 10 to 12
days. Adults can be found in the field until early fall, when they
move to their overwintering sites.

Farming for Carbon
Carbon, especially carbon dioxide, has received a lot of
attention from policy makers and the press lately. But what is
carbon and how does crop management affect it?
