Controlling glyphosate-resistant volunteer corn is a major challenge in some soybean fields this year as preemergence herbicides aren't very effective. Postemergence herbicides will be critical to its management.
Cool, wet conditions in May may be contributing to soybean seedling injury from disease. Scouting is recommended to identify diseases and differentiate injury from that caused by herbicides when determining potential stand loss.
Cool, wet soil conditions in late April and May may have enhanced the potential for soybean injury from PPO-inhibiting herbicides. The author describes plant injury symptoms to look for when scouting young soybean seedlings.
For the week ending June 4, with warmer temperatures and rain limited to the western Panhandle, planting progressed with 6.4 days suitable for fieldwork, according to the June 5 report from the National Agricultural Statistics Service.
For the week ending May 28, cool and mostly dry conditions prevailed, according to the USDA’s National Agricultural Statistics Service. Average temperatures ranged from three to nine degrees below normal. Some areas of the Panhandle and southeast Nebraska received up to an inch of rain; however, much of the state remained dry.
Nebraska soybean and corn yields steadily increased from 1971 to 2016, in both irrigated and rainfed production fields. Charts based on USDA National Agricultural Statistics Service numbers track these changes.
