We need to have a long conversation about nematodes in MS. The first part of that conversation starts with “sample your soil to determine what’s present (species and # present)”. SOIL SAMPLES sent to @MSUextPlantLab ARE FREE through 3/31/2026 @MSSOY @changliunema #mscrops

Septoria brown spot is one of our most common foliar diseases. However, rarely does it become a “problem”, but when it does…. it’ll blow out the top of the canopy. In 18 years, only the fifth time I’ve seen it this bad and the field received a fungicide (QoI + DMI) #mscrops
