Sclerotinia stem rot, or white mold, of soybean is a disease most commonly reported in high-yield soybeans in the North Central Region of the United States. Overall disease incidence and severity vary from year to year and from field to field. In Ohio, growers have faced localized outbreaks of this disease every year since 2009. Infection and disease development are favored by wet conditions and cool temperatures (less than 70 degrees Fahrenheit) prior to, during and following the flowering stage.

Soybean rust (SBR), caused by the fungus Phakopsora pachyrhizi, is one of the most important diseases of soybean in several regions around the world. The pathogen was first identified in Asia but later spread to Africa (1997) and South America (2001). The first report of SBR in the continental United States occurred in 2004, most likely brought from South America by the winds of Hurricane Ivan. It has been proposed that the widespread adoption of soybean as a crop around the world may have contributed in part to this movement.

Calibrating grain yield monitors at harvest can be discouraging and time consuming for a combine operator. However, improperly calibrated yield monitors can generate erroneous data that becomes useless or difficult to interpret. Taking the time to calibrate a yield monitor properly pays off when it comes time to using yield map data for post-harvest analyses or supporting decisions based on your yield data.
