Many diseases start with subtle symptoms that are easy to miss if fields aren't being monitored consistently.
Pay attention to any unusual discoloration, spots, lesions, or changes in plant appearance. Diseases such as leaf rust and stripe rust can spread quickly under favourable conditions, while tan spot and septoria leaf blotch often begin in the lower canopy before moving upward through the crop.
Not all crop issues are disease related. Environmental stresses such as heat and moisture shortages can cause symptoms including leaf rolling, premature maturity, and white heads. These symptoms are often most noticeable in lighter soils, hilltops, and other areas prone to moisture stress.
π If you're unsure what you're seeing in your field, contact your Rep for help identifying crop concerns and discussing the best management options for your operation.
