On April 16, NOAA’s Climate Prediction Center released their climate outlook for May and the coming three-month period of May through July. There is a lot of uncertainty in the temperature outlook for the next one-to-three months in the Northern Plains Region.
This list aids planning and decision-making for 4-H member families and volunteers in light of the ongoing COVID-19 pandemic.
Spring green-up is the time to be watching for black grass bug activity. Large populations of this early-season pest can cause severe damage to pasture (up to 90% forage reduction) and infest the edges of wheat fields.
Soil temperature is an important consideration for deciding when to begin planting spring crops. If producers in South Dakota would like a quick reference for soil temperatures in their area, the SD Mesonet network measures soil temperature at several weather stations throughout the state.
In South Dakota, the spring can come with a wide range of temperature fluctuations. This will affect the performance of burndown herbicides. Depending upon the target weed, type of herbicide and application rate, there will likely be decreased weed control in cooler temperatures.
The goals of applying any crop protection products include: increasing effectiveness, mitigating drift, and maximizing profits. We will focus on mitigating drift, even though all three interact with each other.

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.
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.
Some herbicides can persist in soil, especially dry soil. Herbicide carryover could be an issue in 2021 across the state depending upon last year’s moisture levels and field conditions.
Having a drought plan in place ensures that you can overcome the inhibitions surrounding a drought response, the basis of which is figuring out trigger dates.
