Overwintering S.D. Bean Leaf Beetles: 2017 predicted mortality
The overwintering generation of bean leaf beetle adults emerge in the spring and can cause serious defoliation injury to seedling soybean plants. However, the abundance of overwintering bean leaf beetles is negatively affected when the air temperatures get too cold. Therefore, an estimate of the emerging populations can be made based on how cold the winter was.
Winter Wheat Breaking Dormancy Early
A threshold indicator for winter wheat emergence is to consider average temperatures over a 14-day period. When that 14-day average temperature is equal to or above 5°C, or 41°F, then hard red winter wheat can break dormancy.
Spring Storm Fronts Impact Calving Patterns
While the changes in calving patterns in association with weather fronts is nothing new to producers, it is beneficial to keep this in mind as calving season shifts into high gear. Cold fronts are the type of weather systems that will create the pressure and temperature changes associated with increased birth rates.
