Control Soybean Insects – 2007

The roots and nitrogen-fixing nodules of soybean plants are damaged by several insects that inhabit the soil. This list includes beetle larvae, soybean nodule fly larvae, white grubs and wireworms, etc. Additionally, there are several pests of seedling soybean above ground. No treatment thresholds have been determined yet for these pests and control measures for this kind of damage are not recommended. Seed treatments are currently being evaluated.
