Downy in Soybean
Posted by romeethredge on August 27, 2014
Downy mildew of soybean is being found now in most all the fields I go into at low levels. Downy mildew is easily identified as yellow spots on leaves with a characteristic tuft of fungal growth on the underside of each spot. One may need to look carefully to see the fungal growth, which is typically a grey color.
Dr. Bob Kemerait, UGA Extension Scientist says, “The University of Georgia typically does not recommend spraying fungicides for control of downy mildew because a) the disease is not believed to cause significant yield losses, and b) our fungicides for control of soybean diseases less effective against that type of fungus.”
