Grower Report
Kief, North Dakota grower Myron Dieterle says his sunflowers need rain. He has had no significant rainfall. 19 hundredths of an inch on August 9th and 3 to 4 hundredths on August 11th. His fields are currently at the end of their bloom stage. Hot temperatures during the pollination bloom period affected his sunflower heads. They are filled on the outside but not on the inside. As far as insects or diseases nothing to speak of except for spraying the field perimeter for grasshoppers.
Scout for Grasshoppers
Be vigilant on scouting for grasshoppers. Adult grasshoppers are becoming more common and can do more damage quickly to maturing field crops. NDSU IPM Scouts detected increasing numbers in most areas of North Dakota last week. Action Threshold for Adult Grasshoppers: 21-40 per square yard in field margins or 8-14 per square yard in the field. See maps on NDSU’s IPM website: Grasshoppers — ND IPM (
Nearby and new crop prices established new market highs this week at the crush plants. Old crop was up 20 cents to $1.25 per cwt. with new crop gaining 20 to 50 cents. August 12th was a huge day for commodity markets as USDA released its latest supply and demand report and first report of FSA certified acres. USDA trimmed new crop soybean production average yield by nearly a bushel to 50 bpa, which dropped projected new crop production to 4.339 billion bushels. Both changes were within analysts' pre-report estimate range. USDA boosted old crop soybean ending stocks to 160 million bushels (mb), which was on the high end of analyst estimates, based on lower 2020-21 crush and exports. New crop soybean ending stocks were left unchanged from July at 155 mb.  Globally, old crop soybean ending stocks were boosted 1.32 million metric tons (mmt) to 92.82 mmt, slightly above analyst pre-report estimates. For the new growing season, ending stocks were also on the larger side, at 96.15 mmt, a 1.66-mmt increase from July. USDA Farm Service Agency released its initial reported acres figures this week for all crops. Oil-type sunflower planted acreage was pegged at 1.12 million acres with confection acres at 104,500. The figures were within the average trade estimates. FSA will update the acreage report in mid-September. USDA will provide their initial yield and production estimates for the 2021 oil-type and confection sunflower crop in October.
Examine Crop for Rust
Rust is most often found on the lower under-side of leaves. The pustules are cinnamon-red and readily recognizable. Yield loss can occur, and control measures should be considered when rust reaches approximately 1% severity on the upper four leaves and the plant is in the vegetative stages until it reaches the R6 stage. An infestation on the upper leaves at R6 or later will not likely have a negative yield affect. Fortunately, rust can be managed with well-timed fungicide applications.

Continue Scouting for Insects
With sunflower fields blooming trap catches for banded sunflower moth (BSM) and Arthuri sunflower moths (SM) have increased in the last week and are at economic thresholds for control in some locations. See maps on NDSU’s IPM website: Sunflower Insect Trap — ND IPM ( Severe infestations of RSSW and moths can be very damaging to the sunflower head and result in seed loss. Once the decision to treat has been made, it is critical to time the spray application correctly to get effective management of all sunflower head insects including RSSW, BSM, SM, and Lygus bug. The best sunflower plant stage to treat is when the majority of plants are in the R5.1 growth stage. To read more about scouting for insects and the best treatments, visit
