Crown rot infections are caused by both fusarium and pythium species. These fungi enter the plant via the root system during periods of prolonged saturation, predominately between the V2 and V7 growth stage. Because these fungi persist in higher moisture environments, infections are more prevalent in wetter soils, tighter clay soil textures, higher magnesium soils, and ponded areas of fields. While these infections occur early in corn development, they can persist much longer as the visual signs are not easily detected until later in the grain fill period.

With the next round of treatments for soybeans happening soon, tissue samples are critical to ensure the plant is getting what it needs and confirming that we are applying nutrients that will benefit the crop. This week, sales intern Christy Kettler takes us through some best practices when it comes to tissue testing and some updates on the corn diseases she has been seeing throughout central Indiana.

Corn Disease Update
Last week we reported that Gray Leaf Spot was being found in many corn fields. This week there is Northern Corn Leaf Blight (NCLB) moving into some areas, especially those areas that had a rain early last week.
The next few days are forecast to be well below average for temperatures. Usually this time of year we are talking about heat and drought and its effect on pollination.
Although soybeans appear to be improving, there are still some areas where soybeans are staying yellow. Most of this yellowing has to do with water tolerance.
Most growers in our area have harvested wheat this year and many were surprised by how good the yields were. With the colder than normal winter and warmer than normal temperatures during grain fill, why were the yields so good?
