DOUGLAS B. GUCKER UPDATES



Soil moisture conditions across the three counties vary from normal to moderate drought.
Soybeans planted in April are in the R5 stage (Full Pod), and the April-planted corn is in the R4 stage (Dough), with ear tip kernels starting to dent.
Over the past two weeks, heavy rains have fallen in some areas, and Red Crown Rot is beginning to appear where those high rainfalls occurred. If you suspect Red Crown Rot, send a plant sample to the University of Illinois Plant Clinic for positive identification.
Remember, interveinal chlorosis of soybean leaves can be caused by Brown Stem Rot, Sudden Death Syndrome, or Red Crown Rot.
