Cercospora leaf blight in soybeans
Flown by Adam Shanks, Agriculture & Natural Resources Educator, Purdue Extension – Clinton County
Premature leaf drop triggered the detection of the fungus Cercospora kikuchii which attacks both leaves and seeds of soybeans. The field was flown to see the widespread impact, and the diseased areas were quantified. The disease pattern (in blue) raised questions regarding soil type and influence on the diseased areas. A soil map was layered (in orange) with the annotated UAV map to observe variation, but it appeared independent of the soil type.
