Will Grasshoppers Be an Issue in 2021?

With much of South Dakota experiencing dry conditions this year, grasshoppers are one of the insect pests that will need to be monitored. Large grasshopper populations may cause economic loss in cash crops and reduce forage in range and pasture lands.

Watch Closely for Weed Emergence

Cool, dry conditions have slowed weed emergence and growth, but dry conditions also have limited the activation of preemergent chemicals. Given this scenario, fields need to be scouted closely to ensure that weeds do not get away.

Drought Conditions Magnifying Impact of Black Grass Bugs

With much of South Dakota continuing to experience moderate-to-extreme drought conditions, black grass bugs could become a concern in some areas. Large populations of black grass bugs can cause severe damage to pasture.

SDSU Extension to Resume Drought Hour in May

April 29, 2021

According to the latest U.S. Drought Monitor, nearly 95% of South Dakota is in some level of drought, including 19.42% that is classified as Extreme Drought (D3) in the north central region.

Dry Conditions Could Lead to Early Twospotted Spider Mite Infestations

Although it isn’t an insect, the twospotted spider mite is an occasional pest of crops in South Dakota, and its populations can rapidly increase during dry conditions.

Water Conservation and Efficiency During Times of Drought

As drought conditions continue to expand across the state this year, more thought is given towards South Dakota’s limited water resources. We live in a state where weather conditions and rain patterns seem to comfortably exist at the extremes; we either have way too much or nearly not enough. While this isn’t always the case, it is important to keep in mind that our water resources are finite and all of us should be thinking about doing what we can to protect them.

Using Drought-Stressed Corn as Forage

When drought has compromised tonnage of corn grain, silage producers may still retain part of its feeding value.

Stretching Corn Silage Supplies

During the 2002 drought there was a need to stretch corn silage supplies as a result of the drought that affected the U.S. Now we deal with the opposite scenario, where excessive spring rains have not allowed farmers to get to the fields. In both situations livestock producers face challenges.
