Forage research indicates that, although alfalfa is considered to have good cold temperature tolerance, minor frost damage may occur when plants are exposed to air temperatures slightly below freezing for several hours, and more severe damage will be seen when temperatures drop below 25°F for four or more hours.
Low temperatures during the early morning hours of May 9–11, 2020 may have had detrimental effects on winter wheat in some areas of South Dakota. However, cooler spring temperatures that have slowed the winter wheat development this year may have actually been beneficial to S.D. producers, as later-maturing wheat is not as susceptible to injury from freezing temperatures.
The most common type of pea in American gardens is the shelling pea, also called the “garden pea” or “English pea.” Tender, sweet peas are removed from thin, tough pods before eating.
Snap beans, also called “green beans” or “string beans” (although most modern varieties do not have strings) are harvested when the pods contain immature seeds, and the pods are still succulent.

With alternating cool and warm weather patterns throughout the last few months and the summer season ahead, temperature continues to be a challenge for climate forecasters in South Dakota.
While research has shown that pollinators, specifically honey bees, can’t survive on dandelion pollen alone, this doesn’t mean that the dandelions aren’t still important for pollinators.
Spring planting progress of corn in 2020 has been much ahead of a typical year in South Dakota. Crop development, however, seems slow.
Activity of alfalfa weevils has been documented in many areas of South Dakota during the last week. At this time, the entire state has accumulated enough degree days for alfalfa weevils to be active.
The 2018 and 2019 alfalfa weevil populations were relatively low, and as a result, we didn’t receive very many calls regarding this pest during those years. However, 2020 has been quite a bit different, and alfalfa weevil populations seem to be much higher.
Of all of the potential early season pests, the seedcorn maggot is rarely an issue in South Dakota. However, we have started receiving reports of soybean fields that have poor emergence or seedling stand reductions occurring.
