BushelUp | Late Season Push | 08.18.2026

This week on Bushel Up, the update comes from Aurora following a stretch of much-needed moisture paired with a return of sunshine in the forecast. As corn moves into the final stages of grain fill, attention shifts to late-season management decisions and the common misconception that denting signals the end of yield accumulation. In the field, it’s clear that today’s hybrids continue to build significant starch, kernel depth, and overall weight well beyond the initial dent stage, which makes irrigation, fertility, and crop protection decisions especially critical during this period. Field observations also highlight the importance of scouting for disease pressure, with tar spot and southern rust being monitored closely after recent weather patterns that included humidity, dew, fog, and extended leaf wetness periods. These conditions can create opportunities for disease development, making timely evaluation of fungicide needs an important consideration. At the same time, later-planted and replanted corn is progressing on a different timeline, reinforcing the need to track each field individually rather than assuming uniform maturity across the farm. While the finish line is approaching, yield potential is still very much in play, and continued attention to field conditions, hybrid characteristics, and disease pressure remains key over the next couple of weeks.
