Effects of Spring Flooding on Weed Seed Movement
How does spring flooding impact weed seed movement and dispersal? The flooding that is occurring from spring snow melt may cause weed seeds that are on the soil surface or eroded soil to move, and possibly long distances.
2018 Field Plot Summaries for Wheat Disease Management Trials
The wheat disease management field experiments conducted in the 2018 growing season evaluated several experimental and commercially available fungicides for managing foliar, head or root diseases of spring wheat. Foliar and spike/head diseases incidence and severity were assessed. The field experiments were implemented at Volga Research Farm and Northeast Research Farm (NERF) near South Shore, SD. Results of the same experiment may vary between Volga and Northeast due to environmental differences between the two locations.
Sorghum Weed Control
Early competition, especially from grass, is critical for successfully controlling weeds in sorghum. There are preemergence as well as postemergence herbicides available for this crop. Early treatment provides the best control of broadleaved weeds with crop stage also being a critical factor for some postemergence treatments.
Planting Into Wet Soils
It is evident that there are high chances of planting into wet soils this spring. This is not a good decision when normal soil conditions appear to be attainable, but this year we may not have a choice.
Lady Beetles of South Dakota
Lady beetles are one of the most familiar groups of beneficial insects. Farmers and gardeners appreciate them for devouring insect pests. Both adult lady beetles and caterpillar-like juveniles eat pests.
Woodpeckers Attacking Bur Oaks
Woodpeckers have been seen across the region chipping away at the bark of young bur oak. The woodpeckers can shred most of the bark from young trees, enough that the trees are killed by this injury.
Lady Beetles of South Dakota
A guide for monitoring, properly identify, and promoting the growth of lady beetles.
Herbicide Interactions With Cover Crops After Oats
After oats have been harvested, options exist to keep a living root in the soil. This can be done through growing cover crops. In 2018 an on-farm trial was preformed near Salem, South Dakota to observe how cover crops grown after oats would germinate after common herbicides had been applied.
Wet Conditions Likely Into Fall Season
Many locations in South Dakota have already received as much precipitation this year as they do in an entire average year. The latest climate outlook from NOAA’s Climate Prediction Center shows increased chances of wetter than average conditions to continue into the fall season.
Horse Flies and Deer Flies Becoming Abundant
The above-average precipitation this year has led to increased numbers of horse flies and deer flies across South Dakota. Widespread flooding and an overall abundance of available water has made conditions perfect for these flies.
