Scouting for signs of virus infection
Check for leaf symptoms on young leaves, which show symptoms more readily than older leaves. Scout for plant symptoms of virus during periods of rapid growth and cool temperatures. Symptoms will be most apparant under these conditions than during dry, hot weather.
At soybean maturity, check for seed mottling and for signs of delayed maturity (green stem).
