Managing White Mold in Soybean

July 7, 2014

Farmers in the Midwest may be concerned about white mold (also called Sclerotinia stem rot) in soybean this year. The disease, caused by the fungus Sclerotinia sclerotiorum, is not common every year, but farmers who have battled the disease in the past will want to assess the risk of white mold development as soybeans approach flowering (growth stage R1 – plants have at least one open flower at any node).

Foliar Fungicide Decisions for Late-Planted Crops

July 22, 2019

A new article recently released through the Crop Protection Network (CPN) discusses how to make fungicide decisions in corn and soybean, given the delayed planting scenarios across the Midwest. The article takes into account yield potential at various planting times throughout the North Central region, as well as the previous wet and cool conditions when evaluating for a positive return on investment, in 2019. Also considered in the article is the potential damage that frost can do to overall yield, which also impact your return on investment. 

Sporecaster - Predicting white mold in soybean

Sporecaster is a new smartphone application designed to help farmers predict the need for a fungicide application to control white mold in soybean. The app, which is free to use, was developed with support from the Wisconsin Soybean Association and Wisconsin Soybean Marketing Board. It was programmed by personnel in the UW-Madison Nutrient and Pest Management Program. In this video Iowa State University Plant Pathology graduate student Andrew Penney discusses using the Sporecaster app.
