RSSW Management Workshop
NDSU and SDSU will host a joint workshop focused on red sunflower seed weevil (RSSW) management at the Dakota Lakes Research Farm near Pierre, SD on August 10 at 1PM CDT. The workshop will provide information on biology, scouting and alternative pest management options - early planting of sunflowers to reduce RSSW damage to seeds. In addition, information will be provided from insecticide field efficacy trials for labeled and non-labeled foliar insecticides for RSSW control. Dakota Lakes Research Farm is located 17 miles east of Pierre on Highway 34.
Grower Report
Brighton, Colorado grower Tom Kirkmeyer says his sunflower crop looks good. They are currently in the R-1 stage.  He has seen no insect or disease issues but plans to spray for red seed weevil in the near future. The last two weeks the weather has been in the 90’s and unusually humid for the area. They have had spotty afternoon showers which has kept their moisture conditions good. Last week they did have some hail but looks like there was only minor leaf damage.
Old crop sunflower prices were unchanged with new crop unchanged to up 25 cents at the crush plants this week. The market is watching developments in Russian attacks on Ukraine's crop export infrastructure. Traders did not report any panic buying by importers despite worries that the war could cut off all Black Sea shipments. However recent events have the fate of Black Sea exports more in doubt right now than perhaps they have ever been. Sunflowers are moving into the late bud stage or blooming in the Dakotas and Minnesota. Soil moisture conditions are mostly in good shape compared to last year at this time. However, the crop could use a good drink during this important development phase. It looks like not much will change for weather conditions in the Dakotas and Minnesota, the next two weeks. Above average temperatures and near normal precipitation are expected to continue. In Texas, harvest is moving along making good progress. Commodity traders are starting to get into position for USDA’s August crop reports. August 11th will be a huge day for commodity markets as USDA will release its latest supply and demand reports and first report of FSA certified acres. The FSA figures will be compared to the USDA June acreage report and will give the market a better idea of what got planted this year. This data and weather conditions will guide traders in the coming weeks.
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.

Start scouting for banded sunflower moth and red sunflower seed weevil
As sunflower fields begin to bloom, adults of red sunflower seed weevil (RSSW) will be emerging and will fly to the nearest flowering sunflowers. RRSW are small (2.5 to 3.1 mm long) with a snout and are reddish-orange. Banded sunflower moth (BSM) can be identified by their small size (1/4 inch long) and forewings with a triangular, dark brown band across the middle of the wing. 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 RRSW, BSM, sunflower moth and Lygus bug. The best sunflower plant stage to treat is when the majority of plants are in the R5.1 growth stge. Visit  to read more about scouting for insects and the best treatments.
