This year's planting season had an abundance of rainy days and as a result, many Iowa soybean fields are wet with water pools. The season is ideal for soybean seedling damping off, a disease familiar to producers. With this amount of rain, the first two weeks of June should be the time to find seedling diseases if they occur in your soybean fields. In our fungicide treatment experiments, we already have seen great differences in stand counts between treated and untreated control. Producers who did not treat soybean seeds may experience some damping off and may want to begin scouting for soybean seedling disease. Seed treatment may be needed for replanting if damping off is the cause of reduction. Proper identification of seedling disease also is essential in correcting the problems in the future.
