Symptoms of SCN Damage Apparent Early, Yield Loss Likely Great in 2012

Mid yellowing and stunting of plants caused by SCN

The soybean cyst nematode (SCN) is widely considered to be one of the most damaging soybean pathogens in Iowa every year. Damage from SCN is usually much greater when soil moisture is limiting. The early onset of stunting and yellowing caused by SCN damage in Iowa this season seems to indicate that yield loss to this pathogen is going to be significant - perhaps even on SCN-resistant soybean varieties.
