CROP STATUS
According to NDSU’s (NDAWN) weather center, sunflower planted in central ND on May 25 is fifteen days ahead of last year’s development pace and 5 days ahead of the five-year average. The crop planted on that date is at or near petal drop. Harvesting at this planting date could easily take place in September with a harvest aide, depending on growing degree days from here on. There are late planted sunflower in areas that were too wet for timely planting in the first half of June. This late planted crop is now approaching the bloom period so additional time and growing degree days will be needed for that late planted crop. In general, the sunflower crop throughout the production region is progressing well with good yield potential. Banded moth numbers have declined significantly. Rust does not appear to be at economic levels in any area from the Canadian border to Texas.
