Quality wine grapes can be grown in South Dakota with careful attention to growing site, cultivar selection and production techniques. View selected information available from SDSU Extension and other sources that will help you in deciding whether grape growing is for you, and to grow quality fruit.
The alfalfa weevil is a major spring insect pest of South Dakota alfalfa. Before 2018, this insect was reported as having large populations throughout much of South Dakota. However, during 2018 and 2019, we received fewer reports of alfalfa weevils, which may have been a result of the cooler and wetter spring conditions that were observed.
Due to current grain prices and other reasons, growers may be considering planting spring wheat into fields that were planted to corn or milo last season. While this type of crop rotation is not generally recommended, economic and logistical challenges sometimes may dictate otherwise.
During the last week, the colder weather that we experienced across South Dakota resulted in very little degree day accumulation. However, in some areas enough degree days have accumulated to potentially lead to adult activity within alfalfa fields.
Spring is a busy time for South Dakota farmers and ranchers with planting, calving, and other field preparations. Soil sampling and fertilizing pastures, alfalfa, or other forages might be overlooked.
The arrival of spring in South Dakota means warmer weather and more outdoor activities. However, it also brings an increase in tick activity.
It is finally warming up across much of South Dakota and that means the degree days are beginning to accumulate more rapidly. Alfalfa weevil activity is likely in areas around Rapid City, Hot Springs, Cottonwood, Mission, Pierre, Winner and Vermillion.
Although bean leaf beetles won’t be emerging for a while yet, it is important to be prepared for potential early season defoliation. Once soybean are planted and begin emerging, the overwintering population of bean leaf beetle adults will move into soybean fields and begin feeding on the seedlings.
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.
