Agronomy Talk: White Mold in Soybeans

Author: Eric Wilson

White Mold (a.k.a. sclerotinia stem rot) is a disease caused by the pathogen Sclerotinia sclerotiorum, and if present, can devastate soybean yield. Farmers are often faced with making management decisions that leave them choosing between what is best for disease management and what is best for maximum yield potential.

Concerns for Corn and Soybeans Heading Into Harvest

Author: Chad Kalaher

Record precipitation totals for June have caused concern for corn and soybeans heading into harvest. Many corn fields lost nitrogen and will have a limited ability to adequately fill kernels. Because of this, I expect many corn fields will have ears displaying aborted kernels. In addition, saturated soils may have pre-disposed corn plants to stalk rot infection.

Agronomy Update

White Mold, Soybean Fungicides, and Pollination

Author: Mark Apelt

White Mold
The last year we had a significant amount of white mold pressure was 2009. As you may (or may not) recall, 2009 was below average as far as temperatures were concerned. Highs were generally in the 70s and low 80s and lows were in the 50s and 60s during July. When we look at July 2014 so far, we are following a similar pattern.

Soybean Fungicides: Are they worth it?
We are approaching or are at the R3 stage of soybeans in many fields. The R3 stage is when there are pods developing on the lower nodes (there still will be flowers on the upper nodes as the stages in soybeans overlap). As a general rule, most fungicides are recommended at the R3 stage of growth. The question is, are they worth it?

Checking for Successful Pollination
Many areas are just beginning pollination while many other areas are completing pollination. How successful has pollination been this year? An easy way to determine is to do the shake test.
