Wet Conditions Likely Into Fall Season
Many locations in South Dakota have already received as much precipitation this year as they do in an entire average year. The latest climate outlook from NOAA’s Climate Prediction Center shows increased chances of wetter than average conditions to continue into the fall season.
August 2019 Climate Outlook: Cool and Wet
According to the latest climate outlook update, odds are favoring that August 2019 will be cooler than average. The update was released by NOAA’s Climate Prediction Center on July 31, 2019.
Fungicide Seed Treatments for Winter Wheat
As producers are preparing to plant winter wheat, one of the decisions to make is whether to use a fungicide seed treatment, and if the answer is yes, which product to use.
McFadden and Borlaug: Pioneering Rust-Resistant Wheat
During a brief period of time in the Dakota Territory in the late 1800’s, wheat acreage increased from just over 100,000 acres to well over a million acres. During one year in the height of this heyday, 1897, it has been stated that two-thirds of the world’s wheat was shipped from present-day Eureka, SD, and wagons bearing the crop rolled in from as far as 75 miles away.
Yellow Soybeans
Yellow soybean areas within fields are being noticed in some areas of the state. There are six factors which could be causing the soybean plant yellowing: nitrogen (N), potassium (K), or sulfur (S) deficiency, iron deficiency chlorosis (IDC), soybean cyst nematode (SCN), or yellow flash from Roundup application.
Soybean Pests: Bean Leaf Beetles and Bean Pod Mottle Virus
With the number of bean leaf beetle observations in soybean fields during 2016, the need for monitoring soybean for Bean pod mottle virus (BPMV) development increases. Bean pod mottle virus was first identified in South Dakota in 1998, and is recognized as a very economically important disease in soybean due to the potential for it to cause devastating losses to soybean yields.
Gall Midge Larvae in Soybean Stems
Gall midge larvae were observed recently in soybean stems from a field in South Dakota. These insects were found under the epidermis of the stem that was slightly above the soil line.
Test Your Soil for the Soybean Cyst Nematode (SCN) This Spring
The soybean cyst nematode (SCN) is a major soybean pathogen that causes significant yield loss. Fields that were not tested for SCN last year can still be sampled this spring to determine the presence of SCN or SCN population changes if testing was done in the past.
Pre-weaning Pneumonia in South Dakota Beef Herd: A Persistent Problem, Suddenly Gone
This case report describes a southeastern South Dakota cow-calf herd’s experiences with pre-weaning pneumonia. Unlike many beef herds that experience pneumonia in calves on pasture, this herd’s problems were consistent year after year: widespread calf illness was documented in each of 6 consecutive summers. Anecdotally at least, the occurrence of pre-weaning pneumonia in beef herds is more likely to be sporadic and unpredictable from year to year. This herd’s persistent problems were followed by a year in which, after a change in calf vaccination protocol (informed by herd diagnostics), very little pre-weaning pneumonia was observed.
Bigger Cattle. Warmer Weather. What Can Go Wrong?
The disruptions in the beef processing sector caused by COVID-19 continue to interfere with the orderly marketing of finished cattle. While we all hope that the situation is resolved quickly, the reality is that because the shipment of so many harvest-ready cattle has been delayed, there will be increased numbers of heavier cattle on feed for the foreseeable future.
