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?
