Late-season scouting efforts pay off
Other risks for soybeans include spider mites. Indiana, Illinois, Missouri, Iowa and some areas across the North are encountering this pest. Double-crop or late-planted soybeans have greater potential to host spider mites. Soybeans planted early are past the peak feeding time for spider mites and therefore, are less susceptible.
"Spider mites thrive in hot, dry weather," Bremer says. "Growers should scout the edges and corners of fields first, shaking the bottom leaves over a sheet of white paper. If a grower sees 'moving dirt' they may have spider mites."
As the season progresses, growers in Illinois and Indiana should scout for sudden death syndrome (SDS) due to rains early in the growing season.
"SDS will show up in fields with prime soils. The plant will have yellowing and defoliation in the upper leaves," Bremer says. "Typically the disease is confined to an area and likely will not take an entire field."
If a grower sees SDS in a field, he or she should consider choosing a variety with high tolerance ratings to the disease; Pioneer brand varieties offer growers a choice in level of SDS tolerance.
"Each growing season offers growers the opportunity to reflect and learn lessons," Bremer says. "It's a good time to gather data and use it to make informed seed purchases for the 2012 growing season."
