The last USDA crop progress report indicates 72% of corn in or past the dent stage with 5% of the corn acres mature and soybean with 26% leaves turning color. Heat unit accumulation has been and continues to be slower than normal resulting in a crop that is not maturing as early as planned. With the 50% probability of a 28oF frost generally being mid- to late-October, there is some concern with a fall frost killing the crop before maturity is reached, especially for corn.
