Soybeans are growing quickly. The only serious yield limit this year has been planting date. Brown spot is the only disease I've seen while walking fields. This disease results in speckling of lower leaves and premature leaf loss. It, too, is a result of the wet weather we've had.
Some varieties seem to be more resistant than others.
Many farmers and I continue to be amazed that white mold has not shown up on a large scale this year. I've only heard one report of scattered infections. I have not seen any myself.
