Producers need to plan in advance on how to deal with bare fields that contain an overabundance of weeds. Weeds in these fields have deposited significant amount of seeds on the soil surface, which can easily germinate when adequate moisture and temperature are available.
For many of us, this time of year is tough for our zucchini, squash and pumpkin plants. A close inspection of wilting plants may reveal a sawdust-like substance around the soil surface or on the base of the stem. When pushed, the plants typically break and reveal clear evidence of insect feeding through the stem.
September 2019 has been pleasantly warmer than usual, and our crops need every bit of that warmth to reach maturity before our first frost arrives. Fortunately, temperatures have cooled slightly this week but just to near average for this time of year.
Southern rust was found in a few corn fields scouted last week. This rust is developing very late in the season and therefore its impact on corn yield will be minimal.
One of the insects that starts to attract attention this time of year is the bumble flower beetle.
Ripe fruit that has been injured as well as ground fall fruits often attract undesirable insects into an area.
This week we received a report of insects infesting a soybean field. However, they weren’t insects that we generally think of when the term "soybean insect pests" comes up.
Marestail (also known as horseweed) is considered either a winter annual or biennial species that is often difficult to identify at the rosette stage. In the Dakota’s, marestail will germinate in the fall and bolt in the spring.
2019 has been a year fraught with challenges for ranchers across South Dakota. Abundant precipitation is usually a blessing, however, wet conditions coupled with a cool spring followed by warmer temperatures has caused another problem across the rangelands of South Dakota: ergot poisoning.
