Septoria brown spot

Septoria brown spot is a very common foliar disease of soybean that has been reported to cause insignificant to minor losses.
Septoria glycines is a fungal pathogen that overwinters on infected plant debris and may be seedborne.
Symptoms:
▪ Infections begin on lower leaves and develop later on upper leaves.
▪ Small, dark brown spots (pinpoint to 1/5″ in size) develop on both surfaces of leaves. The spots may grow together to create irregular brown patches.
▪ Infected leaves turn brown and yellow and may drop prematurely.
