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.
