South Central ND (09/15/16)
Based on NDAWN, the region’s rainfall during September 1-13 ranged from 0.4 inches (Brampton) to 4.6 inches (Jamestown). The abundant rainfall received during the last half of summer has produced saturated areas and generally soft soil conditions in fields – hampering harvest besides having wet crops. Hail was still occurring last week (e.g. LaMoure County). On September 14, NDAWN air temperatures reached below freezing (31 degrees F) at Brampton and Harvey.
Dry bean and flax harvest is in progress, with dry bean acres about half completed. Soybean growth stages range from R7-8 (1 pod to 95% pods/plant with mature color) and would expect harvest to begin next week throughout the region (with cooperative weather and soil conditions). Corn will reach maturity the last half of September and sunflower are nearing or at maturity (see picture).
Goss’s wilt (in corn) appears more common in the region this season. As an example, a field in Foster County was infected early with this bacterial disease, resulting in heavy damage (see picture) and currently the plants are completely dried down. Late-season rust can be found in sunflower at significant but not economic (due to late crop stage) severity levels.
