Crop rotation may reduce infection. Long-term crop rotation with corn or small grains may reduce but will not eliminate the disease. Avoid rotating soybeans with white beans, sunflowers or vegetable crops. Searching for genetic solutions to white mold in soybeans. Pioneer researchers have developed a greenhouse screening technique.
Field screening for white mold is very difficult.
Even after two or three years of screening, variation in field environments may not provide conclusive results about the tolerance levels exhibited by specific varieties. Using the new greenhouse screening technique, researchers can now evaluate varieties year-round and measure infection levels accurately in seven to 10 days after inoculating the plants. This will help improve screening accuracy, speed development of tolerant varieties and improve characterization of tolerance levels. Misting systems have been added to four soybean research stations where soybeans are tested for white mold tolerance. The disease requires a cool, humid environment to flourish and now these conditions can be created in areas where they do not regularly occur.
