Black spots, dark or black kernels, and light weight kernels have been an issue for many growers this season. Stink bug damage can be more than just a small black spot. When feeding on the kernel, they can inject digestive materials in the kernel to cause black areas. Embryo rot is found where to the two halves attach. This can be caused by a few different things but "vivipary" is one cause. The pecan germinates in the shuck due to high humidity in the shuck/shell, and high temperatures during ripening. The radicle dies back and leaves the black area where the kernels attach. Shuck decline is another possible cause.
One of the biggest issues this season were the huge crops. Overcropping a tree can affect nut quality greatly. Rainy cloudy spring days and then dry weather during the summer was also another problem for pecan development.
