The soybean stem borer (Dectes texus) is a long horn beetle that can cause lodging in soybean plants, resulting in harvest difficulties and significant yield loss.
Wet and cool conditions during flowering are ideal for development of the fungus Sclerotinia sclerotiorum.
No variety is completely resistant to white mold, particularly under severe disease pressure, but differences in tolerance exist among varieties.
Late season rains are hard on crop root systems. Standing water can cause suffocation-like conditions where oxygen deprived soil cause death to plant roots and subsequent deterioration of above ground foliage.
