Stored Grains and Flooding

According to the Food and Drug Administration, grain inundated by watercourses is considered adulterated and must be destroyed. The portion of the grain that is not affected by the water can still be salvaged for its use.

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.

Flooded Gardens

Soil from gardens that were recently flooded may not be safe for growing fruit and vegetables this summer. Depending on the location, flood waters may contain contaminants or disease-causing organisms.

Septic systems may not always be a homeowner’s first concern during a flood. However, as South Dakotans continue to navigate an exceptionally wet spring, some consideration should be given to your septic system to prevent damage to your home and protect your family’s health.

A Case of Mistaken Caterpillar Identity

Tweets about European corn borer (Ostrinia nubilalis) caterpillars in the stems of conventional corn and feeding in the whorls of corn are crossing my Twitter feed.

Bean Leaf Beetles Are Back: Adults Observed Near Beresford

Earlier this year, we observed a large emergence of overwintering bean leaf beetles throughout much of the state. We are again observing quite a few bean leaf beetles beginning to emerge. These emerging beetles are the result of overwintering beetles mating and laying eggs.

How to Scout For Soybean Gall Midge

Soybean gall midge have been reported in three counties in South Dakota in the past week: Clay, Union and Lincoln. Scouting for soybean gall midge can be as simple as finding wilting or dying plants along the edge of the field, or it can be rather difficult if the plants are currently asymptomatic.
