Information Management to Maximize Your Yields

Sun Scald in Soybeans

Soybeans are starting to show sun scald on leaves, and the amount is higher than normally seen at this time of year.  Sun Scald in soybeans is created by overcast conditions followed by days of bright sunlight and heat, conditions occurring this June.

Sun Scald in soybeans is seen on the top trifoliate of the plant usually where the leaflet has turned over.  The leaves effected often show a distinct line of the exposed surface and the under surface.

Sun Scald in beans shows a brownish, rusty look to the effected leaves.  Unlike a disease, this is not scattered throughout the entire plant making it easy to identify.

These conditions often make the leaves ideal for spider-mites to explore on, but other than that, no yield lost is expected.
